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), type B silica gel, fine-pored silica gel (type A).
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
Type A Silica Gel
Silica gel is tran***rent 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 hasstable chemical properties, does not react with any material except the strong alkali, hydrofluoric acid. Silica gel has open porous structure, high adsorption properties, good thermal stability, stable chemical properties, high mechanical strength, etc.
Silica gel used for gas drying, gas absorption, liquid dehydration, chromatography, catalysts, etc.
Regeneration temperature
Silica gel can be removed moisture by the way of thermal desorption, desorption temperatures as follows:
Type C silica gel¡Ü600℃
Type A silica gel¡Ü200℃
Allochroic silica gel¡Ü120℃
Silica alumina gel¡Ü350℃
Mainly used for drying and moistureproof, may also be used as catalyst carriers, adsorbents, separators and variable pressure adsorbents, etc.
Type B Silica Gel
