Product Details

Water-resistent Silica Alumina Gel

Molecular formula: SiO2.nAl2O3.xH2O

Properties:

Faint yellow,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(liquid water)is in high content.Lower dew point can be true when liquid water exits in system.

Application:

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.
