Classification of silica gel edit

Jun 21, 2016

In General, the silicone can be classified by their nature and composition of organic silicon and inorganic silica gel type.

Is a highly active inorganic silica gel adsorption material, usually with sodium silicate and sulfuric acid the reaction, and after a series of processes such as aging, acid foaming system. Silica gel is non-crystalline substances, whose chemical formula is mSiO2. nH2O。 Insoluble in any solvent and water, nontoxic tasteless, chemically stable, in addition to strong alkali and hydrofluoric acid does not react with any substance. Various types of silicone because of its different manufacturing methods and different pore structures. Silicone of chemical group copies and physical structure, decided has it has many other similar material to replaced of features: adsorption performance high, and hot stability good, and chemical nature stable, and has high of mechanical strength,, family as desiccant, humidity regulation agent, except smelly agent,; industrial as oil hydrocarbon bleaching agent, catalyst carrier, transformer adsorption agent,; fine chemical with separation purification agent, beer stable agent, paint increased heavy agent, toothpaste friction agent, elimination light agent,.

Silicone is an organic silicon compound, refers to the Si-C key, and at least one organic base compounds which are directly connected to the silicon atom, habits are often those with oxygen, sulphur, nitrogen and other organic base connected with the silicon atoms of the compound as organic silicon compounds. Among them, the SI-o bond (-Si-O-Si-) as framework comprising polysiloxane, is the largest organic silicon compounds, studied the deepest, the most widely used class of more than 90% per cent of the total volume.
