Introduction

This product is a kind of fine pored water-resistant aluminum silica gel. It is generally used as the protective layer of fine pored silica gel and fine pored Si-Al silica. It can also be used alone in the case of high content of free water (liquid water).If the operating system contains liquid water, low dew point can also be achieved with this product.

Application

It 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 silica gel, ordinary aluminum silica gel and widely used in industrial oxygen production, hydrogen production, carbon dioxide purification, natural gas purification, refrigerant drying.hollow glass, gas separation and purification, nuclear wastewater treatment, oxygen rich combustion, steel and non-ferrous metal smelting, pneumatic braking,petrochemical, coal chemical and other industries and fields. When the product is used as a protective layer, its dosage should be about 20% of the total amount used.
