Silica gel (Silica gel; Silica) Alias: Silicic acid gel is a kind of highly active adsorption material, which belongs to amorphous material, its chemical formula is mSiO2 Nheo; except strong alkali, hydrofluoric acid does not react with any matter, insoluble in water and any solvent, non-toxic tasteless, chemical property is stable. Various types of silica gel with different manufacturing methods to form a different pore structure. The chemical composition and physical structure of silica gel determine that it has many other similar materials difficult to replace the characteristics: High adsorption properties, good thermal stability, stable chemical properties, high mechanical strength and so on. Silica gel According to its pore size is divided into: macroporous silica gel, coarse pore silica gel, B-type silicone, microporous silica gel.
