Super dry food grade Silica gel desiccant silica gel desiccant
Silica gel desiccant is moisture permeable sachet varieties of silica gel, main raw materials silica gel is a highly porous structure of hydrous silica, nontoxic, tasteless, odorless, chemical stability, with strong Hygroscopicity, is a highly active adsorbent. Usually with sodium silicate and sulfuric acid the reaction, and after a series of processes such as aging, acid foaming system. Silica gel is amorphous substance, its irregular shape transparent spheres, whose chemical formula is mSiO2 · nH2O. So it is widely used in equipment, instruments, equipment, leather, bags, footwear, textiles, foodstuff, medicines, such as the control environment relative humidity in storage and transport, to prevent items from moisture, mildew and rust.
