Crylite; Sodium Aluminum Fluoride What is the product?
Crylite, the English alias of sodium fluoroaluminate. Sodium fluoroaluminate is an inorganic compound with the chemical formula Na
In the industrial field, sodium fluoroaluminate is widely used. In the aluminum smelting industry, it is a key flux. After bauxite is treated to obtain alumina, the melting point of alumina is extremely high, reaching 2050 ° C, and the direct melting energy consumption is huge. After adding sodium fluoroaluminate, the melting temperature of alumina can be greatly reduced to about 950-1000 ° C. This will greatly reduce the energy consumption of the aluminum smelting process, improve production efficiency and reduce costs.
Furthermore, sodium fluoroaluminate is also used in the glass industry. It can be used as a flux to reduce the melting temperature of glass and make glass melting easier. At the same time, it can improve some properties of glass, such as enhancing the mechanical strength and chemical stability of glass. In the enamel industry, sodium fluoroaluminate can be used as a whitening agent to make the enamel surface appear milky and beautiful.
There are various preparation methods of sodium fluoroaluminate. Common ones are made of aluminum hydroxide, hydrofluoric acid and sodium carbonate as raw materials through chemical reaction. There are also fluorite, sulfuric acid, aluminum hydroxide and soda ash as raw materials, which are synthesized by multi-step reaction. In short, sodium fluoroaluminate plays an important role in many industrial production processes due to its unique chemical properties, and is of great significance to the development of related industries.
Crylite; What are the main uses of Sodium Aluminum Fluoride?
Crylite is cryolite, and its chemical name is Sodium Aluminum Fluoride (sodium hexafluoroaluminate). Cryolite has a wide range of uses and is a key additive in the aluminum smelting industry. When covering bauxite for aluminum smelting, cryolite can reduce the melting point of alumina, reduce energy consumption, and increase the conductivity of the melt, making the electrolysis process smooth and improving the yield and purity of aluminum.
In the glass industry, cryolite is also wonderfully useful. It can be used as a flux to reduce the melting temperature of glass, save fuel, and optimize the physical and chemical properties of glass, such as increasing its transparency, hardness and chemical stability. In addition, it can regulate the thermal expansion coefficient of the glass, so that the glass can maintain good performance at different temperatures.
In the field of enamel, cryolite can be used as a whitening agent. Adding it to the enamel glaze can make the surface of the enamel form uniform and tiny crystals, resulting in a milky white effect, increasing the covering power and decorative properties of the enamel. At the same time, it can improve the wear resistance and corrosion resistance of the enamel.
In the foundry industry, cryolite can be used as a casting coating. Applied to the surface of the mold, it can reduce the friction between the molten metal and the mold, make the casting easier to demould, reduce the surface defects of the casting, and improve the quality and smoothness of the casting.
In the field of abrasive materials, cryolite can be used as an additive. Added to the abrasive material, it can increase its grinding efficiency and wear resistance, make the grinding process more efficient, and prolong the service life of the abrasive material. In summary, cryolite has important uses in many industries such as metallurgy, glass, enamel, foundry, and abrasive materials, and is an indispensable raw material for industrial production.
Crylite; What is the production process of Sodium Aluminum Fluoride?
Crylite is the English name of sodium fluoroaluminate. Its production process is exquisite and complicated. Although the ancients did not have modern technology, according to their wisdom, they also had methods to follow.
The first is the preparation of raw materials. It is necessary to obtain pure bauxite, which is the source of aluminum. After fine grinding, the particle size is uniform before it can be entered into the subsequent process. It is also necessary to find the radiant fluorite, which is the source of fluorine, and it has also been treated to make it meet the needs. There is also soda ash, which is of high quality to ensure the purity of the reaction.
The second is the compound reaction. In a special crucible, put bauxite powder, fluorite crushed particles and soda ash in precise proportions. Heat the crucible with charcoal, wait for the crucible to be red, and the fire will become more and more fierce. In the meantime, the craftsman kept his eyes on it and observed the changes. The raw materials quietly change under high temperature, and the molecules blend and gradually become new things. The embryonic form of sodium fluoroaluminate is incubated in the crucible.
Then purify and refine. When the reaction is complete, move the crucible to a cool place and wait for it to be slightly cold. Take the contents of the crucible, wash it with water to remove its impurities. Then filter it with a cloth to obtain the clear liquid. Then steam it over the heat to make the liquid gradually thickened, and the crystallization of sodium fluoroaluminate appears in the container. At this time, crystallization or containing slight impurities, and then a special method, such as recrystallization, to remove its defects, to obtain pure sodium fluoroaluminate.
Finally, the molded packaging. The refined sodium fluoroaluminate, according to the desired shape, is either ground into fine powder or cast into a block. Then wrapped in oil paper and placed in a dry place to prevent moisture from dissolving. In this way, the production process of sodium fluoroaluminate is completed.
Crylite; What is the market price of Sodium Aluminum Fluoride?
Crylite, that is, sodium fluoroaluminate, is difficult to set a certain price in the market. The change in its price is related to many ends.
First, the quality of its quality is related to the quality. If the quality is pure and good, in line with high standards, its price will be high; if it contains a lot of miscellaneous, the quality is at a loss, the price will drop.
Second, the trend of supply and demand determines its price. When the market is very demanding, but the supply is small, the price will rise; if the supply exceeds the demand and the market is large, the price will easily fall.
Furthermore, the cost of production is also a major factor. Its production requires raw materials, manpower, equipment, etc. The price of raw materials is high, or the cost of labor is increased, and the cost of equipment maintenance is increased, all of which lead to higher costs, and the price follows.
In addition, the price varies depending on the place of origin. If the place of origin is close to the user, the freight is saved, and the price is low; if the place of origin is remote, the freight is complicated, and the cost increases greatly, the price must be high.
In today's city, the price of sodium fluoroaluminate is between a few thousand yuan and more than 10,000 yuan per ton. However, this is only an approximate number, and the market conditions are ever-changing. The real-time price can only be confirmed when you consult the merchants in detail or observe the dynamics of the city.
Crylite; Sodium Aluminum Fluoride What are the precautions during use?
Crylite is cryolite, and its chemical name is Sodium Aluminum Fluoride. This product is very important for industrial use. When using it, pay attention to the following things:
First, it is related to toxicity. Cryolite has certain toxicity, and safety procedures must be strictly followed when using it. If the human body accidentally inhales its dust, or causes respiratory discomfort, and even causes more serious health problems. If it comes into contact with the skin, it may also cause irritation. Therefore, when operating, it is necessary to wear protective equipment, such as masks, gloves and protective clothing, to prevent direct contact with the human body.
Second, pay attention to environmental impact. Cryolite degrades slowly in the natural environment, and if it is discharged at will, it is easy to cause environmental pollution. Therefore, during use, the treatment of its waste and wastewater should be in accordance with the recycling standards, properly disposed of, and must not be discharged indiscriminately to avoid adverse effects on soil, water sources, etc.
Third, pay attention to storage conditions. Cryolite should be stored in a dry and well-ventilated place, away from fire and heat sources. Because it encounters hot topics or open flames, it may be dangerous to occur. And it needs to be stored separately from acids and alkalis to avoid reactions and affect its quality and performance.
Fourth, pay attention to the use specifications. In specific use, the dosage should be precisely controlled according to the process requirements and standards. If the dosage is too small, the expected effect may not be achieved; if the dosage is too much, it may cause waste and may also have a negative effect on the follow-up process. At the same time, relevant parameters should be closely monitored during use to ensure the stability and safety of the entire operation process.
