Description
Product Introduction
XINTAO Alumina Silica Gel WS Type
Chemical molecular formula:mSiO2.nAl2O3.XH2O.
This product is a water-resistant silica-alumina gel with a high adsorbent capacity．It is usually used as protective layer in combination with silica gel H type, molecular sieve, and can be used solely when free water (liquid water carry over) is in high content.
Application
It is mainly used as drying agent for air-separation, compressed air dryers and industrial gases, Natural gas dryers for controlling water dew point. It is recommended a layer about 10-20%(wt) should be consider as protective layer in order to increase the reliability of the system.
