Water-resistent Silica Alu-Gel
Silica gel is a kind of high-active absorbing material, which is generally obtained by reaction of sodium silicate and sulfuric acid together with aging, acidic soaking and other series of post-processing. Silica gel belongs to amorphous substance and its chemical formula is mSiO2 . H2O. With stable chemical property, it won't burn and won't dissolve in any solvent except for alkali and hydrofluoric acid. Silica gels of various models form different fined-pore structures owing to different manufacturing methods. Additionally, the chemical components and physical structure of silica gel determine that silica gel owns many characteristics which can't be substituted by other materials of same kind, such as high absorption performance, excellent thermal stability, stable chemistry, high mechanical strength and others.

Product Description
Characteristics
This product is a water-resistant silica-alumina gel with fine pores. It is usually used as protective layer of fine-pored silica gel or fine-pored silica- alumina gel, and can be used solely when dissociated water(1iquid water)is in high content. Lower dew point can be true when liquid water exits in system.
Use
It is mainly used as drying agent for air-separation, compressed air and industrial gases, as ethyne absorbent for preparation of liquid oxygen or liquid nitrogen and as liquid absorbent or catalyst carrier in oil chemistry, electricity and brewery industry, especially used as protective layer of common silica gel and silica-alumina gel. About 20%(wt)should be the percent when used as protective layer.
