2023-04-01 15:29

Characteristics:

Silicone aluminum adhesive appearance is slightly yellow, chemical formula mSiO2. nAl2O3. xH2O. Chemical stability, no combustion, insoluble in any solvent. Microporous silica gel and microporous silica gel compared to low humidity adsorption capacity is equivalent (such as RH=10%, RH=20%), but high humidity adsorption capacity (such as RH=80%, RH=90%) than microporous silica gel 6-10% higher thermal stability than microporous silica gel (200℃) more than 150℃, very suitable for variable temperature adsorption, separation agent.

Use:

It is mainly used for natural dehydration, variable temperature adsorption and separation of light hydrocarbons. It can also be used as catalyst and catalyst carrier in petroleum industry, industrial desiccant, liquid adsorbent and gas separation.
