The material
The material of silica gel sleeve is a kind of high activity adsorption material, belongs to amorphous material, its chemical formula is mSiO2·nH2O. Insoluble in water and any solvent, non-toxic tasteless, stable chemical properties, in addition to strong alkali, hydrofluoric acid does not react with any material. The chemical composition and physical structure of silica gel determines 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 and so on.
