Chemical molecular formula:mSiO2.nAl2O3.XH2O.
Chemically stable,flame-resisting.Insoluble in any solvent except strong alkali or hydroelectric acid. In comparison with fine-pored silica gel ,the adsorption capacity of HY-H silica alumina gel is quite the same when used at low relative humidity ,(e.g.RH=10%,RH=20%),while its adsorption capacity at high humidity is 6—10%higher than that of fine-ported silica gel. Its thermal stability is over 150℃ higher than that of fine-pored silica gel (200 ℃).Ideally suited for use as absorbent and variable-temperature absorbent.
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.
