Water-resistant  Silica Alumina Gel
[Characteristics]
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(liquid water)is in high content.
Lower dew point can be true when		liquid water exits in system.
[Usage]
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.
