Activated alumina desiccant is also called aluminum gel desiccant, mineral desiccant, active desiccant, activated clay desiccant, activated alumina desiccant is white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, strong moisture absorption , After absorbing water, it will not swell or crack and remain intact, non-toxic, odorless, insoluble in water and ethanol.

It is a kind of solid material with high porosity and high dispersibility. It has a large specific surface area. It not only has good adsorption performance, but also has good pressure resistance, abrasion resistance and heat resistance. Therefore, it is widely used as High-efficiency adsorbent, desiccant and catalyst carrier for various reactions. The appearance of activated alumina desiccant is white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, strong moisture absorption, and does not expand or crack after absorbing water. The product is non-toxic, tasteless, odorless, insoluble in water and organic Solvent.

Activated alumina desiccant has many capillary pores and large surface area, which can be used as adsorbent, desiccant and catalyst. At the same time, it is also determined according to the polarity of the adsorbed substance, which has a strong affinity for water, oxides, acetic acid, alkali, etc., activated activated alumina is a kind of low-water deep desiccant, and it is also a drying agent for adsorbing polar molecules. Agent.
