Silica gel (Silica gel, Silica) alias: silicone rubber is a kind of highly active adsorption
material, amorphous material, its chemical formula is mSiO2 · nH2O. Insoluble in water and
any solvents, non-toxic tasteless, stable chemical properties, in addition to the strong
alkali, hydrofluoric acid does not react with any material. each Different types of silica
gel for its manufacturing method and form different microporous structure. Chemical
components and physical structure of silica gel, determines its has many Other similar
materials difficult to replace features: high adsorption properties, thermal stability,
chemical stability, has high mechanical strength, etc. The silicone root According to the
aperture size is divided into: macroporous silica gel, coarse pore silica gel, b-type silica
gel, silica.
