     How does silica gel work?

    Inorganic silica gel is a kind of highly active adsorption material, which is usually prepared by the reaction of sodium silicate and sulfuric acid and a series of post-treatment processes such as aging and acid bubbles.Silica gel is an amorphous material whose chemical formula is mSiO2.NH2O.Insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, except strong alkali, hydrofluoric acid and no reaction with any substances.Different types of silica gel form different microporous structures due to different manufacturing methods.The chemical composition and physical structure of silica gel determine that it has many other similar materials are difficult to replace the characteristics: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, family used as desiccant, humidity regulator, deodorant, etc.Industry used as oil hydrocarbon decolorizing agent, catalyst carrier, variable pressure adsorbent, etc.Separation and purification agent for fine chemical industry, beer stabilizer, coating thickener, toothpaste friction agent, matting agent, etc.
