Product brief introduction
Product Introduction Silica gel procedure for transparent, translucent particles. Divided into two types of spherical and blocky. The main ingredients of SiO2 • nH2O, do not dissolve in water and inorganic acid, hydrofluoric acid and dissolved in concentrated caustic solution. The high mechanical strength, wear resistance. Its internal structure of the pore volume 0.35-0.45ml / g, 20-30 aperture Egypt, the specific surface area ≥ 600 ㎡ / g. The product is an important absorbent, drying applies to various industrial gases, such as air, oxygen, hydrogen and organic gases, and the instrumentation, electrical equipment, textiles, food, pharmaceuticals, photographic equipment, high-end clothing, footwear, containers and various other packaging moisture-resistant materials, organic products refined dehydration and air humidity conditioning, and so on. Adsorption from compressed air and other easily combustible acetylene gas. The performance indicators as shown in the table below:
