:: Characteristics ::
Shape:Pellets.
Color:white or light gray.
Processed and formed from powders.
Besides the adsorption feature possessed by ordinary silica gel, FNG silica gel possesses good water-tolerant property, low break-down rate of reclamation and long service life, etc.
:: Use ::
Mainly used for air drying in the air separating process, the adsorption of acetylene in preparation of liquidified air and liquidified oxygen. It is also used for drying compressed air and various industrial gases. In petrochemical industry, electric power industry, brewing industry and other industries, etc., it is used as l
