Its is mainly used for air drying in the process of air separation as liquid adsorbent and catalyst carrier in petrochemical industry, electric industry, brewing industry, etc. as the protective layer of common si-al silica. When the product is used as a protective layer, its dosage should be about 20% of the total used amount.
