The use of cryolite

It is believed that we should pay attention to safety before using cryolite. We must first understand the properties of cryolite. Only by understanding the properties of cryolite can we better prevent cryolite during the use of cryolite. Here's how to use cryolite safely.

It is believed that cryolite is a corrosive substance. When cryolite contacts the skin, it will irritate the skin, cause corrosive damage to the skin, and stimulate the skin and mucous membranes. If it gets on the eyes, the damage to the eyes will be greater, so we should remember these to prevent these injuries during use. Generally, manufacturers will mark these precautions on the packaging when they leave the factory, so everyone must read the instructions before using them, and then use them after reading the instructions. When using, direct contact of cryolite with our skin should be avoided. Remember to wear gloves and a mask before use to prevent cryolite dust from entering our respiratory tract.

It is believed that cryolite is a substance that is slightly soluble in water, toxic and corrosive, and cannot be used casually. I think many people know the pollution of cryolite to the environment, so it is more important to control the amount of cryolite, and do not touch cryolite directly. It can cause great harm to the human body. If it is mild, it may cause serious injury and poisoning to human skin, so direct contact with cryolite is strictly prohibited.

It is believed that the amount of polymer cryolite in the metal sheet determines the degree of deformation of the product. Appropriate cryolite can prevent mutual contact between multiple layers of metals, which can reduce the degree of wear between products and play a certain role. Cryolite can improve product quality, but excessive addition of cryolite can negatively affect the product. This is why many manufacturers must let them add cryolite in a certain amount when providing cryolite to customers, which can play a certain role. Now many manufacturers strictly control the amount of cryolite to prevent the impact of excessive cryolite on the product.

It is believed that up to now, cryolite production has made great progress in terms of production scale, product variety, and production technology. Especially in recent years, the rapid expansion of my country's electrolytic aluminum industry has further stimulated the development of the cryolite industry. At present, the domestic and foreign cryolite market capacity has expanded to 2.2-2.5 million t/a, and the output value has exceeded 15 billion yuan/a. Market surveys show that due to the rapid development of the aluminum industry, the domestic demand for cryolite has increased year by year in the past ten years.

Especially in the past three years, domestic electrolytic aluminum plants have expanded rapidly, and the demand for cryolite and aluminum fluoride has grown rapidly. Cryolite is a mineral, sodium hexafluoroaluminate (Na3AlF6), white monoclinic (109), slightly soluble in water, molten cryolite can dissolve alumina. Cryolite has a long history of development in my country, more than half a century and decades earlier than other countries in the world. It is used as flux, milky glass and enamel in electrolytic aluminum industry.

Recently, domestic relevant people have analyzed the market development of cryolite and made a research report, pointing out that cryolite has continued to develop so far, mainly in the expansion of production scale, more complete production structure, and more mature production technology. The variety of cryolite production continues to evolve in many ways. Manufacturers believe that the annual output of cryolite is expanding continuously, and the market capacity of cryolite will reach one million tons this year.
