Characteristics
Silica gel is a highly active adsorption material. It belongs to amorphous materials. The chemical formula is mSiO2 & # 8226; NH2O. It is insoluble in water and any solvents, non-toxic tasteless, stable in chemical properties. It does not react with any material in addition to the strong alkali, hydrofluoric acid. Various types of silicone forms different microporous structure because of the different manufacturing methods. Chemical components and physical structure of the silica gel determines that it has many features that many other similar materials difficult to replace: High adsorption properties, thermal stability, chemical stability and high mechanical strength, etc.
Silica gel according to the size of the aperture is divided into: Macroporous silica gel, coarse pore silica gel, b-type silica gel, silica. Because of the different pore structure, the adsorption performance of each have their features. Coarse silica gel in the case of high relative humidity had higher adsorption capacity, pore silica gel, in the case of low relative humidity adsorption amount higher than the coarse silica gel, and b-type silica gel because the pore structure between coarse and fine silica and its adsorption quantity also between coarse and fine mesh. Macroporous silica gel generally is used as a catalyst carrier, flatting agent, toothpaste abrasive, etc. Therefore they should be choosed according to different purposes of different varieties.
