I think we should pay attention to safety before using cryolite. We must first understand the properties of cryolite. Only by understanding the nature of cryolite can we better prevent cryolite in the process of cryolite use. Here's how to use cryolite safely.
Cryolite is considered to be a corrosive substance. When cryolite contacts the skin, it will stimulate the skin, cause corrosive damage to the skin and stimulate the skin mucosa. If it touches the eyes, the damage to the eyes will be greater, so we should remember these to prevent these injuries during use. Generally, the manufacturer will mark these precautions on the package when leaving the factory, so everyone should read the manual before use and use it after reading the manual. When using, we should avoid direct contact between cryolite and our skin. Remember to wear gloves and masks before use to prevent cryolite dust from entering our respiratory tract.
It is considered that cryolite is a substance slightly soluble in water, toxic and corrosive, and can not be used casually. I think many people know that cryolite pollutes the environment, so it is more important to control the amount of cryolite. Don't touch cryolite directly. It will do great harm to 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 considered that the amount of polymer cryolite in the metal plate determines the deformation degree of the product. Proper cryolite can prevent the mutual contact between multi-layer metals, so as to reduce the wear degree between products and play a certain role. Cryolite can improve product quality, but excessive addition of cryolite will have a negative impact on the product. This is why it is important for manufacturers to let customers 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 products.
It is considered that up to now, cryolite production has made great progress in production scale, product varieties and production technology. Especially in recent years, the rapid expansion of China's electrolytic aluminum industry has further stimulated the development of cryolite industry. At present, the market capacity of cryolite at home and abroad has expanded to 2.2-2.5 million T / A, with an output value of more than 15 billion yuan / A. the market survey shows that due to the rapid development of aluminum industry, the domestic demand for cryolite has increased year by year in recent ten years.
Especially in the past three years, the expansion of domestic electrolytic aluminum plants has been rapid, and the demand for cryolite and aluminum fluoride has increased rapidly. Cryolite is a mineral, sodium hexafluoroaluminate (Na3AlF6), white monoclinic system (109), slightly soluble in water, and molten cryolite can dissolve alumina. Cryolite has a long development history in China, 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.
The production scale of cryolite has been studied and developed continuously, and the relevant people have pointed out that the cryolite production technology has been more mature in the domestic market. The varieties of cryolite production are constantly developing in many aspects. Manufacturers believe that the annual output of cryolite is expanding, and the market capacity of cryolite will reach one million tons this year.
