Inorganic silica gel Chemical type Xsio2 YH2O. Transparent or milky granular solid, is a highly active absorbent material, usually with sodium silicate and sulfuric acid reaction, and aging, acid bubble and so on a series of reprocessing process and made of amorphous machine products. It by the natural existence of minerals by washing, processing, become granular or bead-like, the main ingredient of inorganic silica gel, is a silicon soil in the silicate and sulfur acid made of amorphous machine products. Inorganic silica Gel by the natural existence of minerals by washing, processing, become granular or bead shape.
The structure of inorganic silica gel is very much like a sponge body, which is composed of a small pore with a large surface area, which can adsorb and conserve water vapor. Under the condition of 100% humidity, it can adsorb and condense the water vapor equivalent to 40% of its weight. High adsorption performance, can absorb a variety of substances. By adding dilute sulfuric acid (or hydrochloric acid) in aqueous solution of water glass and static setting, it becomes aqueous silicate gel with solid state, good thermal stability, stable chemical property and high mechanical strength.
Inorganic silica gel on the selection of a wide range of materials, generally have opp/pe, pet/pe films, Non-woven fabrics, composite paper. For gas drying, gas absorption, liquid dehydration, color analysis, etc., also used as catalysts. If the addition of cobalt chloride, dry blue, after the water is red.
