Properties:
This product is a kind of fine porous water resistant alumino silica gel. It is generally used as the protective layer of fine porous silica gel and fine porous aluminum silica gel. It can be used alone in the case of high content of free water (liquid water). If the operating system conatains liquid water, low dew point can be achieved with this product.
Application:
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.
