Aluminum Silica gel - light yellow, chemically stable, flame-resistant, insoluble except in alkali or hydrofluoric acid. Superficial polarity, thermal stability, performance greater than fine-pored silica gel.
Silicon aluminum adhesive, chemically stable, nonflammable and insoluble in any solvent. Compared with the porous silica gel, the low humidity adsorption capacity of the porous silica gel is equivalent (such as RH = 10%, Rh = 20%), but the high humidity adsorption capacity (such as RH = 80%, Rh = 90%) is 6-10% higher than that of the porous silica gel, and the thermal stability is more than 150 ℃ higher than that of the porous silica gel (200 ℃), which is very suitable for temperature swing adsorption and separation.
It is mainly used for catalysts and catalyst carriers in petrochemical industry, industrial dryers, liquid adsorbents and gas separation.
