  Detailed Description: Cas No. :112926-00-8;63231-67-4 Specs:Plastic Auxiliary Agents
Silica gel:
Transparent or milky white granular solids. It has an open porous structure with strong adsorption and can absorb a variety of materials. When dilute sulfuric acid (or hydrochloric acid) is added to the aqueous solution of water glass, it will become hydrosilicate gel and become solid. The dissolved electrolyte Na+ and SO42-(Cl-) ions were removed by washing water, and silica gel was obtained after drying. If absorption of moisture, some silica gel moisture absorption of about 40%, even 300%. Used for gas drying, gas absorption, liquid dehydration, chromatographic analysis, also used as a catalyst. If the addition of cobalt chloride when dry blue, water absorption after the red. Renewable and reusable
