Silica gel white includes spherical silica with fine pores and massive silica with fine pores. Spherical silica with fine pores has the appearance of colorless or yellow-transparent or translucent spherical particle, massive silica with fine pores is a colorless or yellow translucent glass-like irregular particle.
Basic quality parameters
The average diameter is 2.0-3.0 nm, ratio surface area is 650-800 m2 / g, pore volume is 0.35-0.45 ml / g, ratio heat 0.92 KJ / kg. Centigrade, thermal conductivity coefficient is 0.63 KJ / m. Hr. Centigrade.
Use
Mainly used as desiccants, moisture beads, agents to remove smell and all kinds of absorbents. Widely used to control relative humidity of the environment for storage and transport of instruments, meters, instruments equipment, leather, luggage, shoes, textiles, food, medicine and so on. It can prevent items from moisture, mildewing and rusting. Because of their high bulk density and obvious effect to absorb moisture in the case of low humidity, it can be used as air cleaner. They are widely used in the sea transport of ocean because the goods during transport often degenerate owing to temperature, the product can be used effectively to absorb water so that the quality of the goods is ensured.
