The main ingredients of liquid silica gel

2022-03-22

1, liquid silica gel is a kind of highly active adsorption material, is an amorphous substance, 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.


2, various types of silica gel due to its different manufacturing methods and the formation of different microporous structure. 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.


3, silica gel according to the size of its aperture is divided into: macroporous silica gel, coarse porous silica gel, B type silica gel, fine porous silica gel. Due to the difference of pore structure, their adsorption properties are different.


4, coarse silica gel in the case of high relative humidity has a higher adsorption capacity, fine silica gel in the case of low relative humidity adsorption capacity is higher than coarse silica gel, and B type silica gel due to pore structure between coarse and fine silica gel, the adsorption capacity is also between coarse and fine silica gel. Macroporous silica gel is generally used as catalyst carrier, extinction agent, toothpaste abrasive, etc. Therefore, different varieties should be selected according to different uses. After absorption of water, silica gel can be regenerated by exposure, baking, air drying and other methods.
