Harsh Environment Cabling The Requirements For Harsh Environment Cabling In The Networking Era Are Getting Higher And Higher. What Are The Key Contents?

July 10, 2025

In today’s era of networking and electronic development, the requirements for Harsh (hard environmental cabling) are getting higher and higher. The so-called Harsh refers to laying and using cables, optical fibers and other wiring systems in a relatively harsh environment. Harsh environments, including deserts, deep seas, mines and other places! There is still a big gap between it and ordinary environmental wiring .

Next, let’s talk about the key content of Harsh in different modules. First of all, the material selection module must be made of materials that can withstand high and low temperatures, chemical corrosion, radiation resistance and other harsh conditions. Materials such as special plastics and synthetic rubber are a good choice. For example, corrosion-resistant polyimide is very competent! Generally, the performance attenuation of these materials at high and low temperatures is at least 30% lower than that of ordinary materials, which is very impressive.

Secondly, the wiring design module. In the design of harsh environment wiring, we cannot simply consider wiring methods like ordinary environments. For example, in a windy and sandy environment like the desert, you must pay attention to burying the cables at an appropriate depth, which can not only prevent wind and corrosion, but also ensure a relatively stable temperature. In some particularly dangerous mines such as gas, explosion-proof and anti-static wiring designs must be used. Professionals must design and plan the direction and curved arc of the wiring. Generally, the bending degree of a cable must not exceed a specific angle, as it may affect signal transmission. Also, be sure to ensure that the cables are connected firmly to various electrical components. Generally, the stability of this connection must be done by a special connection method, which is more than twice the sturdiness of the ordinary connection.

Installing the module. The installation process requires a very rigorous construction. When installing in harsh environments, some advanced tools will be used, such as high-temperature hot melt guns, underwater installation robots, etc. For example, when installing in deep sea, underwater robots can be installed at a certain depth in the bottom of the water, which is very accurate and convenient! However, the installation workers must be well trained! If the worker makes any installation errors, it may be a big deal. It is necessary to always check all parameters during the installation process, the tensile degree, temperature and other aspects of the cable must be controlled. Generally, the tensile strength of a cable must be maintained within a reasonable range.

Then maintain the module. This maintenance is also a long and arduous process. It is crucial and necessary to formulate a plan for regular inspection and maintenance of the wiring system! A monitoring system must also be installed to monitor the signal transmission quality, temperature and humidity of the wiring system in a timely manner. Any minor problems can be detected and repaired as soon as possible. Moreover, the fault plan must be handled in a targeted manner. Different harsh environments must have different solutions! For example, for a wiring failure problem in a desert, the fault range must be determined first. It may be caused by wind corrosion to cause the cable skin to become thinner. Which special repair material should be used to repair it. Repairing the signal strength can greatly improve it. After all, the maintenance conditions in the desert area are limited

OK, let’s answer some common questions here. Q: Can ordinary wiring be used directly in harsh environments? Answer: This is a big mistake! Ordinary materials can not withstand deterioration environments such as high and low temperatures, corrosion, etc. Harsh Environment Cabling, and may be damaged in a short time. Question: Is the wiring cost of harsh environment much higher than usual? Answer: There are improvements, but you consider cost-effectiveness and stability. In the long run, it is reasonable. After all, avoid a lot of troubles of frequent cable replacement and other fees!

Q: Is it okay to just wrap some electrical tape when the wiring connection is loose? Answer: At most, special connection methods and materials must be used for special environments, otherwise their connection reliability will not be sufficient! There is a problem with signal transmission and the risk of failure is quite high! In addition , it provides global procurement services for weak current intelligent products ! Overall, in short, Harsh actually plays a huge and lasting role in ensuring service for various smart devices, communications, etc. in harsh environments. It is certainly said that with the changes in the environment and the development of science and technology, its technology and experience will definitely become more and more mature in the future. I hope that this wiring system will have more development and utilization!
Zero-Gravity Fire Suppression Zero – What Is Gravity Fire Suppression? What Are The Difficulties In Extinguishing Fires Under Zero Gravity?

July 10, 2025

What are we talking about today? Zero – Fire. Actually, this is to extinguish fires in zero gravity or microgravity environments! There is gravity on the earth. When a fire is in trouble, heat and smoke will run upwards, and fire extinguishing will also be used by it. But in a zero-gravity environment, it is completely different. The fire may burn into a strange shape. Zero-Gravity Fire Suppression, without direction, which brings new challenges to extinguishing fires.

1. Difficulties and characteristics of fire extinguishing

Zero – Fire is very different from ordinary fire extinguishing on Earth! When burning on the earth, the rise of hot air will form (convective airflow), which will help to ignite the smoke, making it easier to find the source of fire and the direction of combustion. But under zero gravity, combustion is a shape (spherical), and the combustion diffusion rules are very different. For example, if a fire catches a fire in the space (space station), the fire will not burn upwards, but will spread around it casually, and it may be on fire everywhere.

Because gas won't flow as as on Earth under zero gravity (gas won't flow as regularly as it is on Earth), fire extinguishing agents are also uneven. Fire extinguishing agents may not reach the place they want to go, and they cannot extinguish Mars.

2. Applicable places and scenarios

Space : Zero – Fire is crucial if a small range of devices in space (spacecraft) and (spacewalk). After all, if it burns too much, the entire capsule will be destroyed and the lives of astronauts will be in danger.

(Scientific Experiment) : When doing zero-g (zero gravity simulation cabin) experiments and studying combustion theory and new materials, there is inevitably a fire risk. Using this fire extinguishing method can ensure the orderly conduct of experiments and ensure the safety of personnel and equipment.

Provide global procurement services for weak current intelligent products!

3. Methods and means of extinguishing fires

(Chemical fire extinguishing agent) : There is a very special fire extinguishing material that can react quickly with flames and block combustion (chain reaction). After injection it can spread out under zero gravity and extinguish the fire. For example, Halon-based (Halon-based preparation), which has good effect, but is gradually eliminated because it is harmful to the ozone layer. Now we are also studying a lot of new – (new generation of chemicals), which are environmentally friendly and have good results.

of (isolated oxygen supply) : Close the ignition area and reduce air locks (air lock chamber) (oxygen concentration). In the international space (space station), each module has good sealing performance. Once a fire occurs, it can immediately block the corresponding module. The fire will be wiped out soon after without oxygen.

(Physical fire extinguishing equipment) : Like Fire made of (fire shield made of special materials), it can block heat (heat transfer); fans used for air, evacuating air and reducing combustion opportunities

4. Technical points and key points

the Flame : Designed in zero – a fire (flame detector) that can accurately and sensitively, whether it is (infrared sensor) or (ionization detector), it must be able to capture the fire moment in time. It is important to find timely initial discoveries in some space station fire experiments!

of (effective agent dispersed) : developed-based (pressure-based injector) to ensure that no matter what posture or gaseous condition, the fire extinguishing agent can be distributed well in the space, enclosing the fire source, and all eliminated.

Here are some questions you may have:

Q: What is the difference between the fire extinguishing agent used in Zero – Fire

Answer: It is quite different from the ones used on Earth. Fire extinguishing agent flows on the earth by gravity, but this must be convenient for even dispersing without gravity. It is best to have an environmentally friendly and low-corrosion fire extinguishing agent.

Q: If a very small flame is still needed, does Zero-Fire have an advanced fire extinguishing method?

Answer: Don’t be lucky if you lit a small flame! Under zero gravity, the law of combustion spread is elusive. No matter how small the spark is, it must be destroyed quickly. Don't let it become a big deal and save it.

Anyway, I think this Zero – Fire is too important. In the future, humans will go to space more often. When facing fire risks, they must rely on this fire extinguishing method to protect our astronauts and protect our precious space equipment. When will the real interstellar migration be in the future? Maybe this is the magic weapon for security protection!
Building Psychographic Profiling The Psychological Portrait That Is Worth Discussing In The Current Era Is Extremely Useful In Market Research And Other Fields

July 10, 2025

In this era of complicated information, building a psychological portrait, that is, this is really something worth discussing and studying! The so-called psychological portrait is to deeply analyze the invisible aspects of the inner psychological characteristics, lifestyle, values, emotional needs of an individual or group! This is very useful in many fields, such as market research, precise marketing, and personalized services.

Next, let’s break down the key contents of building psychological portraits in different modules.

1. Data collection

We have to collect all kinds of data related to people’s psychology. Building Psychographic Profiling is like collecting fragments of puzzles. Only by collecting all the fragments can we restore the complete appearance. There are many sources, including social media data. Now social media is a big stage for people to express their feelings and show their lives. Various dynamics, likes and comments reflect their hearts! There are also questionnaire surveys, which set up some in-depth questions to understand people’s preferences and attitudes. However, you need to spend more time designing a questionnaire… and the consumption behavior record can show which products they are interested in and where the consumption level is.

2.Analysis method

First of all, there is a behavioral analysis method. When we observe people’s daily behavior, such as the time, frequency, habits of purchase, etc., we can see many tricks! For example, people who often buy things at night may be busy during the day. The correlation analysis method is also very useful. If you find that many people who buy milk will also buy bread, there may be potential psychological needs here. Cluster analysis method is to aggregate people with the same characteristics together to facilitate in-depth study of their commonalities…

3. Model building level

To build a model, you must base the collected analysis data. Commonly used is the decision tree model, like a layer of forks, which determines people’s psychological types layer by layer based on different data characteristics… and also a logistic regression model to find the logic between specific factors and psychological states. When choosing more models, try different parameters. Only when adjusting them properly can you accurately reflect the subject to study.

There are many details about building a psychological portrait here to talk about in the Q&A

Q: How much is the appropriate data collection?

Answer: It depends on the purpose of the research. If the survey is conducted on a large scale, the sample must be large enough to be representative! If you do a small-scale meticulous research, you can have fewer samples, but don’t forget to have a certain amount of data to ensure scientificity.

Q: Just use one analysis method or try it?

Answer: Well, it is actually best to combine multiple methods, because each method has its advantages and limitations! Maybe one method is easy to use when analyzing a certain phenomenon, but it won’t work if you change the scenario… Multiple methods can be combined to understand the object you want to study in a more three-dimensional and comprehensive manner.

Q: Can the model be universal?

Answer: No! The data attributes of different industries and scenarios vary greatly, and psychological types may not be common. Just like financial data and educational data are completely different, how can we use a unified model… we must build it according to our own needs.

I think building a psychological portrait is very complicated and complicated, but it can bring us great value. It can help you understand the deep-seated ideas and emotions of the target audience, and allow various fields to make adjustments and responses based on actual conditions, which is more helpful to carry out various activities and work. It is worth spending more time thinking about it… Provide global procurement services for weak current intelligent products!

Analysis Of Market Conditions Such As Threaded Hot Coils! Do Coking Coal Ranges Fluctuate Mainly At High Altitudes?

July 10, 2025

Recently, my country's steel and coal markets have fluctuated significantly, and product prices and supply and demand conditions have shown complex and changeable characteristics. Investors need to pay close attention to these changes in order to capture potential opportunities and avoid risks.

The finished material market: the price is relatively strong but the hidden worries are revealed

Yesterday, the price of finished materials fluctuated and the overall trend showed strong momentum. But behind this trend, there are many risks. According to specific analysis, the production of rebar has decreased compared with last month. This change is mainly caused by companies' shift to other products and equipment for maintenance and the reduction in the operating rate of electric furnaces. In addition, the loss of electric furnaces continues to intensify, and concerns about their future start-up situation are increasing. Although inventory has decreased compared with last month, the reduction is gradually shrinking. Demand has been declining continuously, and the month-on-month index shows a downward trend, and is expected to enter a seasonal sales trough soon. Meanwhile, hot coil production rose month-on-month, and the restart of production lines led to a first increase in total inventory, though there is limited room for demand growth. When formulating strategies, it is recommended to focus on short selling at high levels, but it is not advisable to pursue short opportunities too much.

Coking coal market: Futures prices rise and fall

On Wednesday, the coking coal futures market fluctuated significantly, with prices rising first and then falling. The closing price of the 09 contract was 775 yuan, with a decline of 1.71% on the day. The prices of some scarce main coking coal varieties have rebounded, and the trend of falling prices of mainstream coal varieties has also slowed down. The results of London trade negotiations show a neutral and optimistic trend. my country's mining output has declined, but Mongolia's coal imports have rebounded, and the overall supply has remained stable; at the same time, iron and water production has decreased, and downstream enterprises are not willing to replenish inventory. In the short term, futures prices are expected to fluctuate within a certain range; from a long-term perspective, the problems of oversupply and insufficient demand are more obvious. At the same time, we should also pay attention to changes in potential factors such as macroeconomic sentiment.

Coke market: Futures prices fall and face risks of lowering

On Wednesday, coke futures prices fell, with the closing price of the 09 contract at 1,341 yuan, a drop of 0.85%. Last week, the third round of price adjustment measures had been implemented, and this week the Tangshan area also further lowered prices. The decline in coal prices has brought opportunities for profit growth to the steel industry. Despite this, the profitability of steel companies is generally low and the price cut is planned to start next Monday. The decline in coal prices has led to a decrease in coke production costs, but coke prices show a tendency to fall but difficult to rise. In view of this, we suggest to investors that short selling should be considered when coke prices are high.

The thermal coal market: a delicate balance between supply and demand

During the Safety Production Month activity, the increase in production supervision has not caused significant changes to the supply chain. Coal prices in the origin are fluctuating violently. At the same time, coal prices in northern ports remain relatively stable, while imported coal prices are showing a downward trend. The typhoon has limited auxiliary effect on hydropower in coastal areas, while the high temperatures in the northwest and north China have led to an increase in the demand for electricity for residents. Foreign power demand has maintained a stable trend, showing a slight downward trend; the growth rate of power plant inventory has slowed down; the inventory in northern ports has also decreased. It is predicted that coal prices are expected to gradually reach a trough in the middle of the first half of the year, but their room for growth is relatively small.

Market macro environment: policy vacuum and trade results impact

The Sino-US trade negotiations are coming to an end, and my country is currently facing a temporary window of macroeconomic policies. The signing of the London Trade Agreement had some impact on the coking coal and coke markets, but the market's response to this showed diversification. From a macro perspective, many factors are affecting the supply and demand expectations and price trends of the commodity market, and investors should pay close attention to changes in the macroeconomic situation.

Investment advice and prospects

Overall, trading strategies should focus on high-altitude operations and should avoid blindly imitating short selling; in the short term, coking coal prices may fluctuate; in the medium and long term, macroeconomic factors such as oversupply and insufficient demand should be paid attention to; when coking prices are at high levels, short selling strategies can be considered; thermal coal may bottom out in the first and mid-month, but its upward potential is relatively limited. During the transaction process, investors need to comprehensively consider the market foundation, macroeconomic conditions and policy changes of each product. Many people have speculated about which product will be the first to undergo price adjustments in various products to be launched on the market?
Polysilicon Futures Fluctuated On June 11, 2025, Spot Stocks Remained Stable, And Inventory Increased?

July 10, 2025

On June 11, 2025, the latest situation in the polysilicon market attracted widespread attention. In futures trading, price volatility has significantly intensified. However, the price in the spot market remained stable and there were no obvious changes. Under this market prospect, its uncertainty is becoming increasingly prominent. Investors and practitioners are closely watching the development of this situation.

Futures contract fluctuations

On June 11, the price of the main contract for polysilicon futures 2507 fluctuated significantly. The opening price was 33,980 yuan/ton, and rose to 34,255 yuan/ton at the close, an increase of 0.72%. The holdings rose sharply to 60,199 lots. On the same day, the trading volume also soared to 79,861 lots. The market continues to fluctuate, which makes traders nervous and the trading atmosphere extremely active.

Spot prices remain stable

The spot price of polycrystalline silicon remained unchanged on that day. The quotation for re-injected materials is set at RMB 32.00 to RMB 35.00 per kilogram, the quotation range for dense materials is RMB 30.00 to RMB 34.00 per kilogram, and the quotation range for cauliflower materials is RMB 29.00 to RMB 31.00 per kilogram. The price range of granular silicon is locked between 32.00 and 33.00 yuan/kg, the quotation range of N-type materials is 35.00 to 38.00 yuan/kg, while the quotation range of n-type granular silicon is 33.00 to 35.00 yuan/kg. Price stability ensures that the pace of procurement and sales of relevant companies continues.

Inventory output has changed

The inventory status and silicon wafer reserves of polysilicon manufacturers both show an upward trend. Specifically, the inventory of polysilicon has climbed to 26.90, up 0.37% from last month; at the same time, the inventory of silicon wafers has also increased to 20.02 GW, up 7.80% from last month. In terms of output data, the weekly output of polysilicon was 22,000.00 tons, an increase of 1.85% over the previous month; at the same time, the production of silicon wafers was 13.04 GW, a decrease of 2.67% over the previous month. These changes in inventory and output reveal that the market supply and demand relationship is showing an imbalance within a certain range.

Silicon wafer price situation

There is price imbalance in the domestic silicon wafer market. In the N-type silicon wafer product line, the price of 18Xmm-sized silicon wafers is 0.92 yuan per piece, the price of 210mm-sized silicon wafers is 1.28 yuan per piece, and the price of 210R-sized silicon wafers is 1.08 yuan per piece (including tax of 0.00 yuan). The price difference between these silicon wafers of different specifications reflects the market's tendency to demand for different types of products.

Battery price level

The quotation of battery cells remains stable. According to specific analysis, the quotation of high-performance battery cells is stable at 0.27 yuan per watt, while the quotation range of conventional battery cells is generally between 0.25 yuan and 0.28 yuan per watt. The price of half a battery rose to RMB 0.37 per watt. This price stability has had a significant impact on cell manufacturers in formulating production and sales strategies.

Component trading quotes

The trading price of components fluctuates within a specific range, with the specific transaction price ranging from 0.67 to 0.74 yuan per watt. For N-type 182mm size components, the mainstream trading price in the market is roughly 0.69 to 0.70 yuan per watt. As for N-type 210mm size components, the mainstream trading price of the market is also between 0.70 and 0.70 yuan per watt. In addition, the trading trends of the component market are also an important reflection of the polysilicon market conditions.

On June 11, the polysilicon market showed a complex and changeable trend. On this day, the futures market fluctuated significantly, while spot trading seemed relatively stable. As June begins, the production of silicon wafers and battery cells has decreased compared with last month, making the market fundamentals appear weak. Despite this, market sentiment has improved in the short term, and funds have begun to actively participate in market competition, which may trigger large fluctuations in the market. Under the current situation of complex market risks, what are people from all walks of life who have any opinions on the future development direction of the polysilicon market?
The Steel Market Has Changed Many Indicators, And Demand Expectations Are Weak. What Is The Supply Output?

July 10, 2025

Recently, the steel market has shown great volatility, with multiple important indicators volatile, and the overall demand outlook seems to be relatively dull. This phenomenon has caused concern among market participants, who are closely following the changes in the future direction of the market.

Spot price and basis performance

Recently, the steel spot market has shown a stable trend and signs of upward trend have begun to appear; at the same time, the basis has shown a downward trend; especially the hot coil basis, its downward trend is more significant. In East China, the actual trading price of rebar has risen to 2,990 yuan per ton, up 20 yuan from the previous one; in addition, the October futures contract was 1 yuan higher than the spot price. The price of hot coils in East China has climbed to 3,220 yuan per ton, with an increase of 20 yuan. At the same time, the price difference between the main contract and spot stock has a discount of 112 yuan per ton. The fluctuations in spot prices and the shrinking of basis together reveal the current market turmoil and instability.

Supply output status

In the field of steel supply, although production volume has decreased, the decline is not significant. Specifically, the total output of the five major steel varieties in this period decreased by 4,700 tons to 8.8 million tons; among them, the production of rebar decreased by 70,000 tons to 2.18 million tons; while at the same time, the production of hot coils increased by 90,000 tons to 3.287 million tons. During the January-May period, the total iron production increased by 15 million tons year-on-year, with an average daily increase of about 100,000 tons, which fully demonstrates the strong momentum of the previous supply.

Current status of demand side

The demand side is not good, and the demand for major materials continues to decline. This week, due to the impact of the Dragon Boat Festival holiday, the decline was significant, reaching 320,000 tons, and the total volume dropped to 8.82 million tons. Observing the data from January to May, the demand for major materials is roughly equivalent to the output, and the iron increment mainly flows to non-main materials and steel billets. Overall, domestic demand showed a downward trend, while international demand has increased, causing a slight increase in total demand. The inventory of cold-rolled steel continues to rise, which shows that the market demand for steel is changing.

Inventory trends

Steel stocks are approaching the critical value. Among the main steel varieties, inventory fell by 20,000 tons month-on-month, and total inventory fell to 13.63 million tons; rebar inventory decreased by 110,000 tons, to 5.7 million tons; at the same time, hot coil inventory rose by 78,000 tons, to a total of 3.4 million tons; in addition, hot coil inventory began to show signs of accumulation this week. Signs of inventory fluctuations are emerging, and the market supply and demand balance is being affected. It is expected that the market will face in the future.

Cost and profit situation

Coke inventory continues to rise, and its prices continue to fall, thus weakening its support role in cost; at the same time, iron ore inventory has decreased, prices are under pressure, and the overall cost support capacity has declined. Steel prices continue to fall, even lower than the electric cost of electric furnaces, and demand for building materials has declined, while demand for industrial materials has increased, and the profit gap between different varieties has gradually emerged. The combined influence of these factors has caused steel enterprises to face more severe challenges in their operations.

Market Perspectives and Suggestions

Some views point out that steel prices have shown an upward trend in recent times, but their basis shows a downward trend, and the spot market has performed relatively weakly during the traditional off-season period. According to the data of Zhaogang, hot coil inventory continues to grow, and apparent demand has decreased; at the same time, the data of the Ganglian data shows that although the overall output has decreased, it remains at a high level. As demand enters the off-season, overall market expectations are showing a weak state. This month, iron ore shipments showed an upward trend, and inventory levels have approached the historical cumulative high. When implementing trading strategies, investors need to pay attention to possible rebounds in the market and seize opportunities for short selling. In addition, the pressure range revealed by the 20-day moving average of the October contract can be referred to.

Dear readers, the steel market is currently showing complex and changeable characteristics. In view of this phenomenon, what do you think about the future direction of steel prices? Please click to like, forward this article, and look forward to you to leave your valuable opinions and comments.
The Market Trends Of Sugar And Cotton Futures Are Different, And Investors Pay Attention To Changes In Relevant Data

July 10, 2025

Recently, the trends of sugar futures and cotton futures markets are very different, and it is necessary for investors to pay close attention to relevant data. The following is an in-depth analysis of the specific situations of these two markets.

Brazil’s sugarcane harvest accelerates

Recently, the Global Commodity Insight Report released by Standard & Poor’s showed that due to the appropriate climate conditions at the end of May, the efficiency of sugarcane harvesting and pressing operations in southern and central Brazil has improved. The region is expected to crush sugarcane in late May to reach 45.91 million tons, an increase of 1.2% year-on-year. At the same time, sugar production is expected to be 2.84 million tons, a year-on-year increase of 4.7%. This growth trend has had a significant impact on the supply pattern of the global sugar market.

Domestic sugar prices are down

Guangxi Sugar Manufacturing Group set a price range of 6050 to 6140 yuan/ton on the spot quotation, which generally fell by 20 yuan/ton compared with the previous quotation; Yunnan Sugar Manufacturing Group also adjusted its quotation to 5820 to 5860 yuan/ton, with a decrease of 20 yuan/ton. During this period, the raw sugar futures price continued to show a weak trend due to the market’s expectations for increased production. The domestic sugar price fell below the integer level of 5,700 points yesterday. Although the basic price difference remained strong, the market did not rebound significantly. It is expected that futures prices will continue to show a downward trend, and investors need to pay close attention to the changes in subsequent import data.

US cotton prices fluctuate slightly

On Wednesday, ICE US cotton prices showed a slight decline, down 0.01%, and the final trading day closed at 67.7 cents per pound. Meanwhile, the price of the CF509 contract rose slightly from last week, up 0.33%, and ended the transaction at a price of RMB 13,540 per ton. In addition, the holdings of the main contract increased compared with last week, up 7,234 lots month-on-month, and the total volume reached 545,800 lots. The ex-factory price of cotton in Xinjiang and the China Cotton Price Index of 3128B both showed an upward trend compared with the previous day. This change shows that the domestic cotton market has certain room for growth.

International Cotton is concerned about macro

In the field of international trade, the overall driving role of US cotton is not significant, and market focus mainly shifts to the macroeconomic level. The Consumer Price Index (CPI) released by the United States is slightly inferior to market expectations, which in turn triggered fluctuations in the US dollar index and showed a weak trend. At the same time, the planting speed and budding rate of American cotton have decreased compared with previous years, but the proportion of high-quality cotton has remained stable, while the proportion of inferior cotton has decreased. According to the analysis results, it is expected that the US cotton prices traded by the International Cotton Exchange (ICE) will continue to show volatility in the near future.

Domestic cotton market demand improves

In the domestic market, China and the United States have reached a framework for the agreement in principle, and we need to continue to pay attention to the announcement of subsequent specific details. In terms of yarn production, the start-up load showed a slight increase, and the improvement in demand conditions had a positive effect on cotton prices. Despite this, the inventory accumulation problem of textile enterprises has not been effectively solved, and they still face certain operating pressure. Despite this, the weaving factory currently holds insufficient raw material reserves and is expected to replenish inventory in the future. This move may provide some support for the continued rise in cotton prices.

Sugar cotton market outlook

The increase in Brazil’s output has had an adverse impact on the sugar market, causing the futures price to show a relatively negative trend; despite this, the cotton market has seen a price increase due to the improvement of downstream demand, but Zheng Cotton Futures Price may encounter the problem of limited room for upward in the short term. When conducting operations, investors need to consider various factors in a comprehensive way and closely track the immediate changes in relevant data.

The Diplomatic Negotiations Between China And The United States Are Like The Hunger Games, And The Tariff War Behind Late-night Takeaway Is Reversed?

July 10, 2025

As diplomatic officials from China and the United States negotiated on key national affairs, they chose hamburgers as a catering. What kind of economic competition pattern does this method of restricting diet reveal? Let us analyze the truth behind this phenomenon in depth.

A tense start

Members of the delegations of China and the United States are having a significant meeting in Lancaster Palace, London, the capital of the United Kingdom. Since the meeting, the two sides have conducted in-depth exchanges, covering a wide range of issues, including semiconductor export control measures and approval of rare earth export licenses. The documents and materials on the conference table are piled up, and their thickness is even greater than that of ordinary takeaway lunch boxes. As lunch time approaches, US Treasury Secretary Bescent is starting to select dishes. At the same time, Chinese representative Vice Premier He Lifeng decisively proposed to continue discussions, which immediately made the atmosphere at the negotiation site tense.

Confrontation at the takeaway table

After the meal, representatives of both parties held takeaway packaging bags and the dialogue continued. While dismantling the roasted chicken rolls, U.S. Commerce Secretary Lutnik discussed the issue of restrictions on ethane exports; during this period, Chinese Vice Minister Li Chenggang gave different views on the ban on AI chips while enjoying salad. British security personnel couldn’t help but sigh that the collision of tableware on the negotiating table seemed to reveal the truth more than diplomatic rhetoric. The United States is facing challenges brought by rare earth control, and at the same time, China released data on its export performance, a move that made the atmosphere tense and intense.

Internal discrimination between the United States

During the negotiations, core members of the US delegation held a heated discussion. Finance Minister Bescent proposed that the lifting of technology will be used as a condition for the exchange of access to rare earth resources. Meanwhile, Trade Representative Greer insisted on raising tariffs. Commerce Minister Lutnik proposed the strategy of “sacrificing in the short term in exchange for long-term victory.” This scene reminds people of the chaos that occurred during the U.S.-Japan negotiations in May, when the debate between the three representatives led to the stagnation of the negotiation process. At this critical moment, Chinese Vice Premier He Lifeng seized the opportunity and emphasized to the US the necessity of reaching a consensus at the policy level.

The core of the game

US Secretary of Commerce Lutnik responded to the impact of GM and other companies due to my country’s rare earth control policies and proposed the so-called “bargaining list”. This list is intended to relax export controls on 14-nanometer chip manufacturing equipment in order to promote my country to lift export restrictions on seven rare earth elements such as dysprosium and terbium. My representative then presented relevant data to refute and emphasized that practical measures will be taken to support the United States. At this stage, AI chips produced in the United States continue to be subject to export bans. This phenomenon further exposes the increasingly fierce competition between the semiconductor industry and the field of rare earth resource development.

Unexpected results

During the two consecutive days of meetings, participants in the Lutnik venue unexpectedly announced the signing of a framework agreement while enjoying a cold sandwich. At the same time, China has taken a highly-watched measure to limit the validity period of the rare earth export license to August 12, which is exactly the same as the deadline for the 90-day tariff truce. This behavior suggests that if the United States expects to maintain supply chain stability, it must reach a formal agreement with China by the end of the month.

Ending and meaning

In the trash cans at Lancaster Palace, the cleaners discarded the takeaway bags, a move that reflected some subtle changes in historical development. The cooled burger wreck ruthlessly reveals the legend that “U.S. sanctions turn the tide.” Trump’s lament of “China is difficult to tame” has just become the most intuitive portrayal of the changes in the century of historical changes. This negotiation fully demonstrates our country’s wisdom and strength in diplomacy and economic competition. Dear readers, what do you think about the subsequent impact of the two countries’ economic exchanges that may be triggered by this bilateral talks?

On June 10, Hexun Investment Consulting Liu Changsong Analyzed The Reasons For The A-share Diving. Do You Know Why?

July 10, 2025

On June 10, the A-share market experienced a significant decline. What is the driving force behind this incident? What impact will it have on future market trends? This question has attracted close attention from many investors.

Analysis of the reasons for diving

On June 10, Liu Changsong, Hexun Investment Consulting, conducted a detailed analysis of the sharp decline in the A-share market. He pointed out that the significant decline in stock prices this time is the consequence of the interaction between the two factors of information and technical aspects at specific time nodes. At the information level, the decline in the A-share market echoes the performance of other stock markets in the Asia-Pacific region. For example, the Nikkei 225 index also fell, but the specific information that caused the decline is not yet clear. In technical analysis, the decline is particularly important.

The technical cycle reveals

From a technical analysis perspective, the top divergence phenomenon at the daily level is usually accompanied by signals that attract investors to buy. During the trading activities of the day, although the index remained above 3400 points, the period of time it lasted was particularly critical. Since the price of 3040 points rebounded, it has been 43 trading days so far. This period is completely consistent with the 43 trading day cycles spanned by the low of 3140 points hit on January 13, 2025 to the adjustment phase on March 20 of the same year. This phenomenon is undoubtedly worthy of special attention.

Adjustment structure analysis

Since the pullback at 3674 points, the market has undergone four comprehensive adjustments at the daily level, and its pace of rise and fall is characterized by slow first and then rapid. During these four adjustments, each round of adjustments is marked by four representative negative lines. Only after the indicator is repaired will the market gradually enter a moderate rise. Although historical trends will not simply reproduce, similar adjustment patterns are still of significant value for analyzing the current market trend.

Observation of disc features

Analyzing the market trend, if the sharp decline around 3674 points can be effectively avoided, investors will face relatively little risks. When the market structure is adjusted, the market will generally show an upward correction trend after four representative K-lines. In this process, we need to closely track the dynamics of repairing these iconic K-lines and daily-level indicators, rather than focusing on specific price points, because the points of the Shanghai Composite Index have already deviated to a certain extent.

Support judgment method

In terms of evaluating support strength, the performance of the Shenzhen index is more significant among similar indexes. This judgment is mainly based on features such as M head and neck line gap or ABC wave morphology. From the perspective of ultra-short-term trends, there is a need for adjustment in the 60-minute cycle indicator, so after the large-volume negative line appears, it is not advisable to rush to chase the positive line in the adjustment stage to avoid unnecessary losses.

Double Innovation Index

In the Double Innovation Index sector, performance failed to meet expectations. The ChiNext fell by 1.17% on the day, and the Science and Technology Innovation 50 Index fell by 1.47%, not only offsetting the previous day’s increase, but also accompanied by an increase in trading volume. This situation reflects the obvious pressure on the market to sell. Investors have been warned before, reminding them to pay attention to the risk of inducing multiple risks, and recommending to operate with caution. It is currently impossible to determine whether any investors have successfully avoided the risks.

The market will inevitably face new development opportunities, but the premise of this change is that we need to accurately identify key trends with significant growth potential. At present, an urgent problem to be solved has emerged, that is, everyone is generally concerned about the duration of this market adjustment. Here, we sincerely invite you to share your views in the comment area, and please do not forget to like and forward this article.
