Activated alumina is white spherical porous granules, smooth surface, uniform particle size, non-toxic, odorless, tasteless, insoluble in water, alcohol and organic solvents, but insoluble in acids and alkalis. Yuanying activated alumina has strong moisture adsorption, high mechanical strength, big specific surface area, large pore volume, high pressure-resistant, high wear-resistant, stable chemical properties, not burst after absorbing water There are the following types of products: activated alumina desiccant, defluorination agent, activated alumina catalyst carrier, activated alumina for hydrogen peroxide, sulfur recovery catalyst, potassium permanganate ball, dechlorination agent.
