Silica gel desiccant is a highly active adsorbent , usually prepared by reacting sodium silicate and sulfuric acid, and through a series of post-treatment processes, such as aging and acid foam. Silica gel is an amorphous substance and chemical formula is mSiO2+nH2O, which is Insoluble in water and any solvent, non-toxic and tasteless, chemically stable, in addition to strong base, hydrofluoric acid does not react with any substance. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace with other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. This product is packaged in a moisture permeable pouch. Different kinds of silica gel, the main raw material silica gel is a high-porosity structure of hydrous silica, non-toxic, odorless, chemically stable, and has strong hygroscopic properties. Therefore, it is widely used in the storage and transportation of instruments, equipment, leather, bags, shoes, textiles, food, medicines, etc. to control the relative humidity of the environment, to prevent moisture, mildew and rust.
There is clear technical specifications for the desiccant packaging and test methods. Silica gel has a strong adsorption capacity and can cause dryness on human skin. Therefore, work clothes should be worn during operation. If the silicone enters the eye, rinse with plenty of water and see a doctor as soon as possible.
