1. Used as a binder for various refractory materials, with strong adhesion, high temperature resistance (1500-1600°C), etc.
2. It can be used in the coating industry to make the coating firm, and it can also resist dirt, dust, aging, fire and other functions.
3. For thin shell precision casting, can make shell type strength, casting finish high. Its shape is better than that of water glass, and instead of ethyl silicate, it can reduce costs and improve operating conditions.
4. The silica sol has a high specific surface area and can be used for catalyst manufacture and catalyst support.
5. Tape used in the paper industry, can be used as cellophane anti-adhesive, photographic paper pre-treatment agent, cement bag anti-slip agent.
6. It is used as a sizing agent in the textile industry. It is used together with an oil agent to treat the spinnability of wool and rabbit hair, to reduce breakage, prevent flying, increase yield, and increase economic efficiency.
7. Used as silicon steel sheet processing agent, picture tube dispersant, floor wax anti-sliding and so on.
