Silica gel desiccant is a highly active adsorbent material, which is usually prepared by reaction of sodium silicate with sulfuric acid and a series of post-treatment processes such as aging and acid foaming. Silica gel belongs to amorphous substance and its chemical formula is as follows:mSiO2.nH2o。 Its shape is transparent sphere, insoluble in water and anysolventIt is non-toxic, tasteless, stable in chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid. Chemical Constituents of Silica Gel andPhysical structureIt has the characteristics that many other similar materials are difficult to replace. Silica gel desiccant has high adsorption performance, good thermal stability, chemical stability and high mechanical strength. Therefore, it is widely used.instrumentInstruments, equipment and equipment, leather, bags, shoes, textiles, food, etc.DrugsThe relative humidity of the environment should be controlled during storage and transportation to prevent dampness, mildew and rust.
