B type silica gel particles moisture-proof mildew absorbent desiccant raw materials

The B-type silica gel is between coarse and fine porous silica gel, with pore volume of 0.60-0.85 mL /g, average pore size of 4.5-7.0nm, and specific surface of 450-650m2/g. Uses: Mainly used as air humidity regulator, catalyst and carrier, as well as used as chromatography silica gel and other fine chemical products raw materials. Therefore, the desiccant is widely used in instruments, instruments, equipment and instruments, leather, bags, shoes, textiles, food, drugs and other storage and transportation control of the relative humidity of the environment, to prevent moisture, mildew type B silica gel for milky white transparent or translucent spherical or massive particles. The structure of type B rubber hole is between change and rust. It has clear provisions on the technical indexes and inspection basis and inspection methods of desiccant for packaging. Safety performance of silica gel: silica gel has a strong adsorption capacity, can produce dry effect on human skin.
