The main raw material silica gel is a kind of water containing silica with high microporous structure. It is non-toxic, tasteless and odorless. It has stable chemical properties and strong hygroscopicity. It is a kind of highly active adsorption material. It is usually prepared by the reaction of sodium silicate with sulfuric acid and a series of post-treatment processes such as aging and acid bubble. Silica gel is an amorphous substance with transparent irregular sphere shape, which is widely used in the drying and moisture-proof of electronic products.
