Sodium silicate and sulfuric acid are usually used, and after aging, acid bubble and so on a series of after treatment process and make. The silica gel is an amorphous substance, and its shape is irregular, and its chemical formula is mSiO2 and nH2O. Which is widely used in instruments, meters, instruments, leather, bags, footwear, textiles, food, medicine and other transport and storage of the control environment relative humidity, to prevent the goods from moisture, mildew and rust.
