Quantity: 200Metric Tons Specs:1-3, 2-4, 3-5 Price:700 USD Metric Tons Payment Method: TT Type A Silica Gel Application Mainly used for drying and moistureproof, may also be used as catalyst carriers, adsorbents, separators and variable pressure adsorbents, etc. Introduction 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 the 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. Regeneration temperature Silica gel can be removed moisture by the way of thermal desorption, desorption temperatures as follows: Type C silica gel≤600℃ Type A silica gel≤200℃ Allochroic silica gel≤120℃ Silica alumina gel≤350℃ |
