Type B Silica Gel

Our firm is a very prominent name of the market for manufacturing, exporting and importing of Type B Silica Gel in Pingxiang, Jiangxi, China. Mainly used for liquid absorbent, humidity regulator, desiccant, catalyst, catalyst carrier, spices carrier, silica sand, pet bedding, whitening agent and used as the raw material of chromatography silica gel and other fine chemical products.
Silica gel is transparent or ivory-white granular solid, main ingredients are amorphous silica. Silica gel does not dissolve in water and any solvents, non-toxic tasteless, not burning. Silica gel has stable chemical properties, does not react with any material except strong alkali, hydrofluoric acid. Silica gel has open porous structure, high adsorption properties, good thermal stability, stable chemical properties, high mechanical strength, etc.

Added dilute sulfuric acid (hydrochloric acid) into the aqueous solution of sodium silicate and let standing, thus becoming solid aqueous silicate gel. Used water washing to remove Na+ and SO4 2- (Cl-) ions dissolved in the electrolyte, after drying it is silica gel. Different manufacturing methods form different microporous structure, different microporous structure form different models, such as macroporous silica gel, silochrom (type C silica gel), type B silica gel, fine-pored silica gel (type A silica gel).

Silica gel used for gas drying, gas absorption, liquid dehydration, chromatography, catalysts, etc.
