Silica gel is a kind of transparent or milky white granular solid, its main composition is silica, chemical property is stable. Silica gel has an open porous structure and extremely strong adsorption, which can absorb a variety of substances and produce drying effect on human skin. It can be used in gas drying, gas absorption, liquid dehydration, chromatography and so on.
Silica gel is a kind of high activity adsorption material, which belongs to amorphous substance. Depending on the nature, silica gel can be divided into organic silica gel and inorganic silica gel. Organic silica gel is mainly used as a special material for aviation, cutting-edge technology and military technology. Inorganic silica gel can be used as a desiccant and can be reused. The Inorganic can also be used to make the case of the mobile phone, with extremely high impact resistance.
The application of silica gel is widely in life, we need to distinguish its true and false : from the appearance, the fake silicone wrist strap is easy to deform, the real silicone rubber is very good. When the silica gel is burned, the fake silica gel produces black smoke and the remainder is black powder. Real silica gel products is producing white smoke, burning residual is white powder.
