This product is a χ-ρ white spherical porous particle with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, does not swell or crack after absorbing water and remains in its original shape, non-toxic, odorless, and insoluble in water and ethanol.
The particle size can be processed according to user requirements, from 1-12mm
Main uses
This product has a white spherical shape with many capillary channels and many capillary pore channels. The surface of these pore channels has high activity and has the ability to selectively adsorb gas, steam and liquid moisture. The dry dew point can reach 40°C. It is widely used in the steel, textile, electronic industries, petroleum cracked gas, gas and liquid phase deep drying and purification agents in ethylene and propylene, pressure swing adsorption desiccant in the air separation industry, etc. Activated alumina balls are also determined according to the polarity of the adsorbed substances. They have strong affinity for water, oxides, acetic acid, alkali, etc. They are an efficient desiccant for deep drying of trace amounts of water and also adsorb polar molecules. Due to the high net heat of the monomolecular adsorption layer, the adsorbent is very suitable for dry heatless regeneration devices.
