Brief introduction of Slica gel: Water Absorbing Agent Silica Gel desiccant is a highly active adsorption material, usually obtained from the reaction of sodium silicate and sulfuric acid, and the aging, acid bubble and a series of post-processing process. Silica gel is amorphous material, the chemical formulas is mSiO2·nH2O. It is insoluble in water and any solvent, avirulent and insipidity. With the chemical stability, except strong alkali and hydrofluoric acid, it will not react with any material. The chemical components of silica gel and physical structure, decided that it has many features which other similar material is difficult to replace. Silica gel desiccant is widely used in the storage and transport of apparatus and instrument, mechanical equipments, leather products, bags and suitcases, footwear, fabrics and medicines to protect them from moisture, mould and corrosion as its strong adsorption performance, high thermal stability, chemical stability, high mechanical strength, etc. Main Feature: Adsorption performance, high thermal stability, chemical stability, high mechanical strength, etc Typical index: SILICA :MIN 98.5% BULK DENSITY:784 G/L SIZE:1-3mm,2-4mm,3-5mm,5-8mm
