Inorganic Silica Gel

Inorganic silica Gel is a highly active absorbent material, usually with sodium silicate and sulfuric acid reaction, and through aging, acid bubble, such as a series of reprocessing process. Silica gel is a amorphous substance whose chemical formula is mSiO2. nH2O. Insoluble in water and any solvent, non-toxic tasteless, chemical property stability, in addition to strong alkali, hydrofluoric acid and no reaction with any matter. Various types of silica gel because of their different manufacturing methods to form a different micro-pore structure. Chemical composition and physical structure of silica gel, decided that it has many other similar materials are difficult to replace the characteristics: high adsorption performance, thermal stability, chemical properties, stable, high mechanical strength, such as desiccant, humidity regulator, deodorant, etc. industry used as oil-hydrocarbon decolorizing agent, Catalyst carrier, pressure swing adsorbent, etc. Fine chemical separation and purification agent, beer stabilizer, coating thickener, toothpaste friction agent, matting agent.

Silica gel According to its size is divided into: macroporous silica gel, thick-hole silica gel, B-type silica gel, microporous silica gel. Because of the different pore structure, the adsorption properties of them are characteristic. Thick-hole silica gel in the case of high relative humidity has a higher adsorption capacity, fine-pore silica gel in the case of low relative humidity, the absorption of adsorption is higher than the coarse silica gel, while the B-type silica gel due to the hole structure between coarse, thin hole, its adsorption capacity between coarse, thin hole.

Inorganic silica Gel According to its use, can also be divided into beer silica gel, PSA silicone, medical silicone, discoloration silicone, silica gel desiccant, silicone openings, toothpaste with silica gel.

Organic Silicone

Silicone is a silicone compound, which is a compound containing si-c bonds and at least one organic base that is directly connected to the silicon atom, and is often used as a silicone compound for compounds that connect organic to silicon atoms by oxygen, sulfur, and nitrogen. Among them, polysiloxane with silicon oxygen bond (-si-o-si-) as the skeleton, is the most of silicone compounds, the most research, the most widely used category, about 90% of the total dosage.

Silicone is mainly divided into silicon rubber, silicone resin, silicone oil, silane coupling agent four categories.

Silicone products According to the different molding process can be divided into three major categories
