:: 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 silicaalumina 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.
