Inorganic silica gel is a highly active adsorbent

Inorganic silica gel is a highly active adsorbent material, usually prepared by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid foaming. Silica gel is an amorphous substance with a chemical formula of mSiO2. nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silica gels have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace with other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc., household desiccant, humidity Regulators, deodorants, etc.; industrial use as oil hydrocarbon decolorizer, catalyst carrier, pressure swing adsorbent, etc.; fine separation agent for fine chemicals, beer stabilizer, paint thickener, toothpaste friction agent, matting agent, etc.
