Silica gel is applied as adsorbent to an osushka and purification of air as in after meshcheniye with big humidity, and the air given to compressors. For drainage of industrial and natural gases (carbon dioxide, hydrogen, oxygen, nitrogen, chlorine and others), for drying and clarification of some liquids Widely use silica gel for purification of various industrial oils. Also silica gel finds broad application in the industry (pharmacy, metallurgy, sewage treatment and dr). Production - Russia. China
Silica gel (silicon dioxide amorphous, anhydride of silicon acid) represents translucent or pretty grains white or yellowish (because of impurity) colors, in the dried-up state is fragile, we will dissolve a little and does not bulk up in water and organic solvents. It is the dried-up gel which is formed of the oversaturated solutions of silicon acids. Firm hydrophilic sorbent.
On the structure silica gel is the high-porous body formed by the smallest spherical particles, has huge surface area, on a chemical composition - SiO2 silicon dioxide (silicon dioxide).
It turns out at acidulation of solutions of silicates of alkaline metals with the subsequent washing and drying of the formed gel.
Commodity silica gel is let out in the form of grains or spherical granules. Various brands of silica gels have the average effective diameter of a time 20-150 Angstrom (1 Angstrom = 10-10 meters) and a specific surface of 100-1000 m ²/g.
