Brief introduction


Silica gel is a highly porous, noncrystalline form of silica used to remove moisture from gases and liquids, to impart a dull surface to paints and synthetic films, as well as for other purposes.

Silica gel is made of silicon dioxide, a highly active adsorbing material with micro-pore structure that is usually formed through the reaction between sodium silicate and sulfuric acid, polymerization and gelatinized, depurated
and drying.

A-typ Silica Gel is also called TS6 silica gel or fine pored silica gel. Appearance looks transparent or translucent
glass-like spherical or irregular granules.

Its average pore diameter: 2.0-3.0 nm
specific surface area:: 650-800 m2 /g
pore volume: 0.35-0.45 ml/g
specific heat: 0.92 KJ/kg.ºC
thermal conductivity: 0.63 KJ/m.hr,ºC

A-typ silica gel is mainly used for drying and moisture resistance, may also be used as bayalyst carriers,
adsorbents, separators and variable-pressure adsorbents, as well desiccant for sachets etc.

Owing to its chemical and physical structural characteristics, silica gel has many superior qualities that other similar materials can never replace, such as,

1) adsorption capacity
2) selective absorption
3) thermal stability
4) chemical stability
5) abrasion proof
6) dynamic resistance etc
