Silica gel

We are offering Silica Gel. Yuanying silica gel does not dissolve in water, any solvents, non-toxic tasteless, not burning. It has stable chemical properties, does not react with any material except strong alkali, hydrofluoric acid. It 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).
There are type A silica gel, type B silica gel, type C silica gel, silica gel cat litter, silica alumina gel, blue silica gel, orange silica gel, FNG silica gel, pressure-changing adsorption silica gel
