1. Physical Description:

Silica Gel Adsorbent - water proof PNG — Molsivcn

Water Proof Silica Gel

1. Physical Description:

Shape: Beads
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.

2. Application Field:

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 liquid adsorbent and catalyst carrier. It may also be used as the buffer drier, silica sand etc. for ordinary silica protective bed.
