Activated alumina balls, also known as activated alumina, the English name for ActivatedAlumina it is a porous, high dispersion of solid materials, a large surface area, with its porous surface adsorption properties, fluoride removal, drying, surface activity, good thermal stability, the appearance of white spherical porous particles of uniform size, smooth surface, high mechanical strength, moisture absorption, no swelling after absorbing maintain the status quo does not crack, non-toxic, odorless, insoluble in water, ethanol . And has a high strength, low wear, not powder, not rupture characteristics. Drying is widely used in petroleum cracking depth of dry gas, air separation plant, instrument air-dry machines, hydrogen peroxide, fluoride treatment, Kaiou use of foreign advanced technology, processing with high-quality materials, high compressive strength, long life, and more regenerations.
