Activated Alumina Balls High Quantity White Alumina Ball
Activated alumina, also known as activated bauxite, is called activated alumina. Alumina used in catalysts is usually called "active alumina". It is a kind of porous, highly dispersed solid material with large surface area. Its microporous surface has the characteristics required by catalytic action, such as adsorption performance, surface activity, excellent thermal stability, etc., so it is widely used as catalyst and catalyst support for chemical reaction. Spherical activated alumina PSA is a white spherical porous particle. The particle size of activated alumina is uniform, the surface is smooth, the mechanical strength is high, and the moisture absorption is strong. After absorbing water, it does not expand and crack, and remains unchanged. It is non-toxic, odorless, and insoluble in water and ethanol. Activated alumina is an efficient desiccant for deep drying of trace water, which is suitable for heatless regeneration
