Activated alumina ball
Presents in white beads, uniform granularity, smooth surface, large mechanical strength, can not be dissolved in the water and organic solvent, but it can be dissolved in the strong acid and alkali solution. It has strong ability of moisture absorption, and can not swell and crack after absorbing water and keep the original shape at the same time, It is innoxious, flavourless.Main usage: as absorbent, it is mainly used in different kinds of hydrocarbon gas, natural gas, petroleum cracking gas to absorp, Dehydrate, which belongs to the universal type. As fluorine-removal agent is mainly to remove the fluorine in the drinking water, industrial water; As recycling agent, it is used in the anthraquinone process hydrogen peroxide as absorbent. As dechlorination agent, it is mainly used for dechlorination in the different kinds of gases and viscosity resin liquid; As catalyst carrier, it is mainly used for all kinds of catalyst carrier. As air drier, it is used as drier in the air.Physical Properties
