Description:
A fine-pored silica alumina, which generally acts on the protective layer of fine-pored silica gel and fine-pored silica-alumina glue. It can also be used alone when the content of free water (liquid water) is high. When the operating system contains liquid water, this product can also achieve a relatively low dew point. It is not easily broken,wear-resistant,strong adsorption, long service life and good cost performance, can reduce the production cost in practical application.
