silica sol
1: In the field of refractories, it is widely used as a binder, which ensures the stability of refractories with its strong adhesion and high temperature resistance (resistant to high temperature of 1500-1600 ° C).
2: In the coating industry, its application makes the coating more solid, and has multiple functions such as anti-fouling, anti-aging and fire prevention, effectively extending the service life of the coating.
3: In terms of precision casting, it can enhance the shell strength and improve the casting finish. Compared with water glass molding, its molding quality is better, and the cost is lower, and the operating conditions are also improved.
4: In the field of catalyst manufacturing and catalyst support, its high specific surface area characteristics make it an ideal choice, effectively improving the performance and efficiency of the catalyst.
5: In the paper industry, it is used as a cellophane anti-stick agent, photographic paper pretreatment agent and cement bag anti-slip agent, etc., to improve the quality and performance of the product.
(1) Adsorption: The network structure pores formed by countless glue agglomeration give it a strong adsorption capacity, which can adsorb inorganic substances and organic matter.
(2) Specific surface area: It has a large specific surface area, usually reaching 250 ~ 300m/g, which makes it excellent in many applications.
(3) Adhesion: It will produce a certain bonding strength after its own air drying, if it is mixed with fiber or granular materials and dry curing, it can form a hard gel structure, significantly improve the adhesion.
(4) Temperature resistance: generally can withstand high temperatures of about 1600 ° C, showing good temperature resistance.
