Activated Alumina Ball Series 活性氧化铝球系列
It is White spherical porous particles, uniform size, smooth surface, mechanical strength, moisture absorption. It maintains the status quo (no crack & expansion) after water absorption. It is non-toxic, odorless, and insoluble in water and ethanol.
In certain operating conditions, and regeneration conditions, the depth of the product drying can reach under temperature of -70 degrees of dew point. The product can be used as fluoride removal agent (fluoride removal capacity) in high-fluoride drinking water, alkanes defluorination agent in the benzene production cycle, and transformer oil regeneration deacidification agent. It is used for oxygen industrial, textile industry, gas drying for electronics industry, air drying for automation instruments, as well as desiccant drying and cleaning agents ( dew point can be up to -40 degrees)in fertilizer, petrochemical and other industries. The dew point pressure swing adsorption can be up to -55 degrees in the air separation industry. It is a trace of water depth and efficient desiccant drying which is suitable for non- thermal regeneration device. (25kg / bag)
