Inorganic silica gel
- Nov 12, 2018 -

Inorganic silica gel is a kind of highly active adsorption material, which is usually made by sodium silicate and sulfuric acid reaction, and a series of post-treatment processes such as aging and acid bubble. Silica gel belongs to amorphous material, and its chemical molecular formula is msio2.nh2o. Insoluble in water and any solvent, non-toxic tasteless, stable chemical properties, except strong alkali, hydrofluoric acid does not react with any substance. Different types of silicone have different microporous structures due to their 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, etc., household used as a desiccant, humidity regulator, deodorant; Industrial use as oil and hydrocarbon decolorizer, catalyst carrier, variable pressure adsorbent; Fine chemical separation and purification agent, beer stabilizer, coating thickener, toothpaste friction agent, extinction agent.
