Introduction:
a kind of alkali aluminosilicate and able to adsorb molecules with their critical diameters no more than 3A .According to the industrial application specialties, our products have the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery polymerization for cracked gasses, ethylene, propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials.
