What is Zinc Sulfide

Zinc Sulfide:

Its chemical formula is ZnS. Its molecular weight, 134.72. The zinc ions, Zn2+ and sulfur ions, S2- are able to interact through ionic interactions. The sulfur ions form a regular tetrahedron in which the zinc ion sits in the middle. The sulfur ion occupies the center of the tetrahedron. This structure can also be described as a facecentered cubic system where zinc and sulfur are located in the vertex of the crystal and at the center of the face.

Zinc Sulfide (also known as Zinc Sulfide) is an insoluble, white solid. It is not soluble in water. However, it is soluble with bases and acids. Zinc sulfide's density is 3.98 g/cc, with a melting and boiling temperature of 1 350 degrees C. The light transmission range of zinc sulfide is between 200 and 400nm. Zinc sulfide has relatively stable properties, but under certain circumstances it can react. Zinc sulfide is oxidized, for instance, when it comes into contact with an oxidizing substance. In an environment that is alkaline, zinc hydroxide can be formed by the reaction of zinc sulfide with hydroxide.

Application of Zinc Sulfide

Zinc sulfide, also known as zinc sulfur, is a significant compound. The unique crystal structure and chemical and physical characteristics of zinc sulfide have made it a widely used compound in many fields. We will discuss the various applications of zinc sulfide.

1. Manufacturers of phosphor

Zinc Sulfide has many uses, including in fluorescent screens. Zinc sulfide, used in the manufacture of fluorescent screens, can be made into phosphors, which can then emit light to display an image when they are excited by external lights. In the manufacture of fluorescent lamps, zinc-sulfide also makes phosphors which emit visible light upon being excited by ultraviolet radiation.

2. Manufacturing of photoelectric conversion materials

Zinc Sulfide, a material used for photoelectric conversion, can also be used in the manufacture of solar cells. Zinc sulfide converts light energy into electrical power in solar cells. The photoelectric efficiency of zinc sulfide, combined with its low cost, makes it a material that has wide applications.

3. Drug Manufacturing

Zinc Sulfide, because of its biological activity, has many applications in pharmaceutical production. Zinc sulfide is used in the manufacture of anti-malarials, including zincsulfate as well as zinc acetate. The zinc sulfide used can be used for the production of preservatives, fungicides as well as other products.

4. Catalyst Manufacturing

5. Optical device manufacturing

Due to its high transparency, zinc sulfur is used widely in optical devices. Zinc sulfide is used, for instance, in optical fiber communication to produce optical fiber preforms. Additionally, zinc sulfide may be used to make optical devices like optical Windows and lenses.

Method of Production of Zinc Sulfide

1. Method of chemical precipitation

The chemical precipitation method is the most common way to prepare zinc sulfide. The zinc sulfide was obtained by mixing zinc salt with sulfur salt.

Preparation Solution: Dissolve a suitable amount of zinc salt and sulfur salt into water to create a solution.

Precipitation reaction : the above solution is heated in stirring conditions and a precipitating agent of appropriate amount is added to precipitate sulfur ions as well as zinc ions. This results in zinc sulfide.

Filtration : The reaction is filtered in order to obtain a filtrate that contains zinc-sulfide precipitation.

Cleaning: The filtered precipitation of zinc sulfide is cleaned with alcohol in order to remove impurities.

Drying: After washing the zinc sulfide it is precipitated then dried to get zinc sulfide.

Chemical precipitation is easy to do, inexpensive, and produces a product of high purity. The disadvantages of this method are that it requires a large number of detergents and precipitating agents. Also, the waste liquid generated must be further processed before being discharged, which can cause environmental pollution.

2. Synthesis of solid phases at high temperatures

Traditional methods for the preparation of zinc sulfide include high-temperature solid phase reactions. A solid reaction between zinc oxides and sulfur-containing elements was used to produce zinc sulfide.

Ingredients: To make raw materials, the appropriate amount of carbon powder, zinc oxide powder, and sulfur dioxide powder is mixed.

Pretreatment - The raw materials undergo a pretreatment at high temperature to ensure that all components react and generate zinc and sulfide vapor.

Synthesis: Zinc and sulfur vapors are produced at high temperatures.

Collection: The powdered zinc sulfide is collected and processed accordingly.

The high-temperature, solid-phase synthesis is characterized by high purity, excellent crystallinity, as well as a relatively straightforward process. The method does require high-temperatures and a lot of carbon and sulfur powders, which can cause some environmental pollution.

3. Solventothermal Method

The solvothermal process is a method that has been developed to prepare zinc sulfide. The method is to dissolve zinc salts and sulfur salts in organic solvents under high temperature and pressure, and then generate zinc sulfide by hydrothermal reactions.

Solution preparation: Dissolve a suitable amount of zinc salt and sulfur in an organic solvent.

High temperature and pressure reaction: The solution above will be placed in a high temperature and pressure reactor. Under these conditions, the hydrothermal reactions will produce zinc sulfide.

The generated zinc powder is collected, and treated as required.

The solvothermal technique has a number of advantages including a high degree of product purity, good crystalline quality, and comparatively simple processing. To regulate product properties, this method uses different organic solvants and reaction conditions. The method is not without its limitations. It requires high-temperature, pressure equipment. And the recovery and disposal process of organic solvents are expensive and require certain technology.

It is important to consider the advantages and limitations of different methods of production of zinc sulfide, and to select the appropriate methods according to actual conditions and needs. During the production, it is important to take into account environmental protection and safety. Adopting appropriate environmental protection technologies and measures will help reduce the harm caused to the environment and humans.

The Federal Reserve continues to raise interest rates accordingly to curb global steel used iowa precision cut to length line demand growth

The Federal Reserve continues to raise interest rates accordingly to curb global steel product name demand growth

The Federal Reserve continues to raise interest rates process, for the domestic steel market both positive and negative, will not change the domestic steel market wide shock pattern.

First, the Federal Reserve and other central banks began the process of continuous interest rate hikes

The Federal Reserve recently raised its benchmark interest rate by 75 basis points to a range of 1.50% to 1.75%, the biggest increase since 1994. The Fed had already raised rates twice, first by a quarter point, then by a half point, this time by 75 basis points. The Fed statement also said it would continue to raise interest rates, but ruled out increases of 75 basis points each time. There is a view that the Federal Reserve in July to raise interest rates 50 basis points is still a large probability event, September is likely to continue to raise interest rates 50 basis points, a total of 300 basis points is expected this year.

At the same time, since this year, the world's major central banks have also started or accelerated the process of interest rate hikes. Recently, India and Australia have started a new interest rate hike cycle again. The European Central Bank also announced an end to monetary easing and will raise interest rates in July.

Second, continue to increase interest rates to curb global steel demand growth

The immediate goal of the Fed and other central banks to raise interest rates so sharply is to tame surging inflation, but the side effect is to stifle economic growth and increase the risk of recession. According to the latest economic forecasts released by the Federal Reserve, the median FORECAST of US GDP growth for this year, next year and the next three years is 1.7%, 1.7% and 1.9% respectively, which are all significantly lower than their forecasts in March. The World Bank recently downgraded its global growth forecast again. The economic slowdown in the United States and the world and the increase in the risk of recession will inevitably lead to a corresponding global steel demand restraint, which is not good news for China's steel export demand, especially indirect steel export.

On the other hand, the worsening global growth environment will also increase the counter-cyclical adjustment efforts of Chinese policy makers to stimulate domestic demand and ensure that the economy operates within a reasonable range.

Why is Polycarboxylate Superplasticizer Modified?

The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring:  Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the concrete superplasticizer ? 

Concrete water reducing agent is one of the technical ways to reduce the cement dosage, improve the utilization rate of industrial waste residue, and realize the durability and high performance of concrete. It is also one of the key materials for the development of concrete to high-tech field. And polycarboxylate type water reducing agent (PC) has become a kind of efficient water reducing agent with the most rapid development and the largest market potential because of its low toxicity and environmental protection characteristics.  Compared with the traditional admixtures, the admixtures have become the focus of worldwide research and development because of their excellent dispersibility and slump retention ability. 

Although polycarboxylate water reducing admixture outstanding performance and ability to maintain good slump has been widely recognized, but because of the existence of mineral composition, cement fineness, cement plaster form and content, admixture adding amount, and the mixing process of concrete mixture ratio, water has a very high sensitivity, seriously affected the existing products are widely used in engineering. 



What is Polycarboxylate Series Water Reducing Agent?

Polycarboxylate superplasticizer is a kind of surfactant containing carboxylic graft copolymer. Its molecules are comb shaped and have high steric hindrance effect. As the third generation of high-performance water reducing agent after lignosulfonate ordinary water reducing agent, naphthalene series aliphatic group, sulfamate and other high-efficiency water reducing agent. 

It is because of molecular structure design performance is good, high reduce water, low admixture amount, keep slump good, enhance good, contain alkali amount is low, to set time influence is small, and most cement compatibility is good and pollution-free and other advantages are regarded as the most development potential of water reducing agent variety.


Polycarboxylate superplasticizer is a new high-efficiency superplasticizer developed and produced successfully after naphthalene, melamine, aliphatic and sulfamate superplasticizer.  In its content is low (solid content 0.15% - 0.25%) can produce an ideal water reducing and enhanced effect, less impact on the setting time of concrete and slump retention, adaptability to cement and admixture is relatively good, a smaller influence on drying shrinkage of concrete (usually not too much increase drying shrinkage), without the use of formaldehyde in the process of production and does not discharge waste liquor, SO  The low content of 42- and Cl- has been praised by researchers and some users since the beginning. 


Why should Polycarboxylate Superplasticizer be Modified? 

Compared with naphthalene series high efficient water reducing agent, such as, although poly carboxylic acid water reducing agent in the reduction of water conservation slump has obvious advantages in aspects of environmental protection, but there are some technical problems in the practical engineering application, such as water reducing effect of concrete raw materials, mixing ratio, water reducing agent dosage dependence is very big, fresh concrete performance is sensitive to water consumption, easy preparation of large liquidity segregation layer. Poor compatibility with other water-reducing agents and modified components and poor product stability greatly restrict the wide application and development of polycarboxylate water-reducing agents. 


In order to overcome the technical defects in the application of polycarboxylate water-reducing agent, or to improve some or some properties of concrete (workability, slump retention, reduction of bleeding, improvement of early strength, low shrinkage, etc.), it is necessary to modify the concrete. 

In practice, the commonly used modification methods include synthetic technology and compound technology. Compared with the synthetic process, the compound method has the advantages of simple operation and low cost, so it is widely used in practical applications. Polycarboxylate series compound technology, is the polycarboxylate series water-reducing agent and other components (such as slow coagulation, defoamy, air induction, early strength and other components) according to a certain proportion of the combination compound, in order to achieve the coordination of the superposition of each component.

The declaration of a state of emergency in the United States due to power shortages affected the market for the timer with relay

Market Analysis of timer with relay

Time relay Industry competition and marketization degree: relay industry development is more mature, the market competition is more sufficient, major producing countries including China, the United States, Japan, Germany, etc., including the United States, Japan, Germany enterprise occupies most of the high-end relay market share, is mainly used in industrial automation control, automotive, communications, aerospace and other fields. The output of relays of Chinese enterprises accounts for about half of the global output of relays, but they are mainly medium and low-end products, which are mainly used in household appliances, electricity, automobiles and other fields.

President Joe Biden has declared a national emergency over power shortages, ordering an increase in generating capacity and the purchase of additional solar panels from Asia.

The emergency measures to meet consumer demand came as U.S. fuel prices doubled during his time in office, leading to rising inflation, the report said. Against this backdrop, Biden's approval ratings are at record lows.

The president's statement released on Thursday (local time) is the first official acknowledgment by the White House of the reality in the U.S. nearly a year and a half after Biden took office. "As president of the United States, empowered by the Constitution and law, I declare a state of emergency because of the threat of insufficient electric power to meet consumer needs," the statement said.

Biden cited "a number of factors" preventing the United States from producing the electricity it needs, from problems in international energy markets due to the situation in Ukraine to extreme weather conditions. He called for a focus on the active use of solar energy. To that end, the United States will exempt imports of "certain components and modules" for solar panels from Cambodia, Malaysia, Thailand and Vietnam for two years or until the state of emergency is lifted. In addition, he proposed to encourage domestic solar panel production in the United States under the Defense Production Act.

The "electric emergency" comes a day after AAA released its latest data on fluctuations in the country's gas prices during the Biden administration, the report said. The average price of regular gasoline in the United States hit a record high over the weekend. Mr. Biden blamed the conflict in Ukraine, rather than government failures, for fuel price increases that have fueled the highest U.S. inflation in 40 years.

How to assess the special situation in the U.S. economy and consumer market, and how well the White House has managed the crisis, has become a major issue of debate. In an Ipsos/ABC News poll conducted Tuesday, only 37 percent said they had a positive view of Biden's policies to revive the economy, while 61 percent said they had a negative view. Measures to reduce inflation were approved by 28 percent and criticized by 71 percent. At the end of May, after nearly a year and a half in office, Biden's approval rating had fallen to an unprecedented 36 percent, and if he fails to turn the tide, he risks becoming the worst president in history after Trump, whom he labeled the worst president in history.

Basic concept and principle of relay: relay is a control component that automatically disconnects when the input parameters (such as electricity, magnetism, light, heat, sound and so on) in the circuit reach a specified value, which can make the output parameters of the circuit change in a predetermined step. In circuits, relays mainly control, protect, regulate and transmit information. The relay has an induction mechanism that reflects external input parameters, an executive mechanism that realizes "on" and "off" control of the controlled circuit, and an intermediate comparison mechanism that compares, judges and converts the size of the input.

As a control element, relays have the following functions:

(1) Expand the control range, such as multi-contact relay control signal reaches a certain value, according to the different forms of the contact group, at the same time open and close the multi-circuit;

(2) amplification, such as sensitive relay, intermediate relay, etc., with a very small amount of control, can control a large power circuit;

(3) comprehensive signals, such as when multiple control signals are input into the multi-winding relay in a specified form, after comparison and synthesis, to achieve the predetermined control effect;

(4) Automatic, remote control, monitoring, such as the relay on the automatic device and other electrical appliances together, can form a program control circuit, so as to realize automatic operation.

In the competition of the timer with relay market, enterprises in the United States, Japan and other developed countries constantly consolidate their dominant position in the global market by establishing technical standards, controlling core technologies, strengthening the integration of industrial chains, and firmly mastering the dominance of technical standards and international rules.

A rebound in oil demand in Asia and Europe search to fill the Russian gap also had an impact on the market for the cord grip cable gland

A rebound in oil demand in Asia and Europe's search to fill the Russian gap also had an impact on the market for the cord grip cable gland

French finance minister Bruno Lemaire said on Sunday that France was in talks with the United Arab Emirates to replace Russian oil purchases. After the European Union imposed a ban on Russian crude oil, French oil procurement will stop.

On the other hand, the international crude oil supply is becoming increasingly tight. As Asia enters a period of economic activity, Saudi Arabia's oil price for the Asian market has risen more than expected. Oil prices began to climb as shipments increased in July.

Aramco raised the price of its main Arab light crude oil for Asian customers by the US $2.10 to the US $6.50 per barrel in June, higher than the benchmark price is used. A survey of refiners and traders shows that the market expects oil prices to rise by $1.50.

Saudi Aramco raises oil prices as the market tightens

Aramco also raised the prices of all grades of products for northwest Europe and the Mediterranean region. Prices for U.S. customers remained unchanged for the second consecutive month.

Due to the sanctions of the United States and Europe, the crude oil from Russia decreased and the market tightened. In addition, Asia's economy began to enter a period of activity.

OPEC + agreed on Thursday to accelerate production. The 23 nation cartel led by Saudi Arabia and Russia said that it would increase 648000 barrels of supply to the market every day in July and August, about 50% more than the increase in production in recent months.

Nevertheless, most analysts said that the group was unlikely to achieve its goals because many member states, even outside Russia, were trying to increase production. Saudi Arabia and the United Arab Emirates are about the only OPEC + countries with large idle capacity. More than 60% of Saudi Arabia's crude oil is exported to Asia.

The cord grip cable gland industry background

industry background Wire and cable are widely used in all departments of the national economy, which is the fundamental guarantee for the regular operation of the modern economy and society. The development level of the wire and cable industry is also a symbol and epitome of a country's manufacturing level. Europe, America and Japan, such as developed countries, early industrialization at the end of the 20th century, have formed a mature cable industry chain . Contributed to most of the global cord grip cable gland capacity and demand at that time, still occupied an important position in the worldwide supply and marketing, leading the industry's development and monopolizing the global high-end market.

1. The slowing growth of global cord grip cable gland demand has accelerated under the epidemic situation

According to the use scenario, the commonly used international cord grip cable gland divide into two categories indoors and outdoor. Outdoor cord grip cable gland due to wind and snow and environmental climate, working conditions, so its structure is more complex. Indoor cord grip cable gland working conditions are better and do not need a waterproof device. The cable core can directly connect with equipment. At present, indoor and outdoor cord grip cable gland for 10KV and below and outdoor cables sometimes use metal cord grip cable gland . According to data released by CRU, in 2021, global demand for metal cord grip cable gland (conductor weight) slowed significantly due to weak demand in China, with 19 million tons in 2021, up nearly 1% year on year. CRU reported in December 2022 that the global market for cord grip cable gland except in China would shrink by almost double digits in 2021 due to the impact of the pandemic.While market demand is recovering, early weakness will drive double-digit declines in multiple regions in 2021. As a result, the global need for insulated metal cord grip cable gland will shrink by about 5% -6% yearly. According to preliminary estimates, the global demand for metal-insulated wires and cables will fall to 17.86 million tons in 2022.

2. The outbreak has led to lower demand for cord grip cable gland , and The size of the global market is gradually shrinking

The wire and cable market size are above 20 billion dollars as one of the most important manufacturing industries globally. From 2018 to 2021, the market size of the global wire and cable industry generally showed a trend of fluctuation. According to the data released by CRU, the market size of the international metal cable industry was $161 billion in 2019.Up slightly to $172 billion in 2020. The global market size fell slightly to $164 billion in 2021 due to falling demand in China. According to preliminary estimates, the global metal cord grip cable gland market in 2022 was affected by the epidemic, shrinking demand, with market size of $152 billion.

3. The market share of cord grip cable gland in the Asia-Pacific region gradually expanded, and the other areas began to shrink

In recent years, the economic growth of emerging countries and other Asian countries has been fast. The production focus of the world wire and cable production has shifted to Asia, which has driven the rapid development of the wire and cable industry in China, Vietnam, the Philippines and Egypt in the Middle East.According to the report released by the CRU, the outbreak in 2021 led to different effects on the world's other parts except for China. Combined with multiple market data, we summarize the overall development of the power cable industry in the global scope. Manifested by the rapid rise in Asia, the slight decline in America, and the unstable growth in Europe in recent years, which is greatly affected by economic and political factors. The Asia-Pacific region accounts for about 49% of global consumption, while Europe and the Americas account for 15% and 10%.

4. The cord grip cable gland market in Europe, America and Japan is relatively mature, with a high concentration degree

After years of developing the wire and cable industry in developed countries, especially in the face of fluctuations in raw material prices, small enterprises gradually withdrew from the market, and the industrial concentration increased significantly. The top 10 American cable manufacturers (GM, Best, Corning, South, etc.) occupy about 70% of the market share. Seven Japanese cable enterprises (such as Wuhe, Sumitomo, Tengcang, Hitachi, Showa, etc.) account for more than 65% of the market share. Five French cable enterprises (Nexan, etc.) occupy the French market turnover, occupying more than 90% of the French market share. And China's entire wire and cable industry concentration is deficient. CR10 is 17.7%.

5. Emerging markets in cord grip cable gland have increased significantly

In 2021, the global cord grip cable gland market was in turmoil due to the COVID-19 pandemic. As the global economy recovers, China invests in new energy and infrastructure construction, and the global cord grip cable gland market is expected to recover in 2021. The global metal cord grip cable gland market will rebound to $180 billion in 2022.However, in the medium term, the global wire and cable industry will return to healthy growth, driven by government and private investment, after the end of COVID-19 but slowing slightly from the previous five years. Among them, represented by Africa and Southeast Asia, the rapid development of emerging market economies will accelerate their construction, infrastructure, utilities, and industrial development activities. These activities will provide the substantial upward potential for emerging market wire and cable demand. Emerging market demand growth will continue to support the recovery and growth of global demand.

According to the CRU forecast, after 2023, the international wire and cable industry market demand will recover to the level of 2019. The international wire and cable market is expected to expand at an annual growth rate of 5% from 2022 to 2026. The global cord grip cable gland industry market will reach $230 billion in 2026.

Why does properly poured concrete end up cracking

It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete?

1. The cement proportion problem: Some workers in construction will add more water for a more fluid concrete. However, this will result in an increase in water-cement ratio. This will cause the concrete to harden too quickly, and lead to cracking.

2. Transport and mixing issues: If mixing and transportation of concrete is prolonged, the water in the concrete could evaporate rapidly and cause rapid loss. concrete . This leads to a concrete that is weaker on the construction site, unable to meet construction specifications.

3. Construction speed

4. Maintenance is unreasonable. During the period of maintenance, if late watering isn't maintained, the result will be the Cracking phenomenon Later in the year, concrete will be used. Concrete is used in later stages of the Concrete Surface Watering You can water the concrete often to speed up the drying process. Concrete will shrink if it is not watered. Late cracking occurs when concrete strength is decreased.

5. Environmental factors: If the environment at the construction site is relatively dry and there is high temperature, wind, or both, then the evaporation rates of the concrete are accelerated. This results in cracking on the concrete's surface. Concrete constructions are most likely to crack in the winter or summer because of the temperature difference.

Solution: Add a crack-preventing agent. A composite anti-cracking agents made of inorganic materials can prevent foam concrete from fracturing by more than 80%. Add 2 to 3 kilograms per cubic foot.

It is possible to obtain molybdenum by flotation. This method involves the use of organic agents and grinding molybdenum or tungsten sources with minerals like pyrite, sphalerite or sphalerite. This method is able to produce molybdenum products with high purity, but requires a more complicated production process and more organic agents.

Electroplating is the process of electroplating molybdenum on a metal surface. By using this method you can create molybdenum-disulfide films that have excellent properties. However, the chemicals and waste liquids in the electroplating will pollute the surrounding environment.

Different production methods offer different advantages and drawbacks. You should choose the best method for your needs. It is also important to consider environmental protection and safety during the production process.
