The activated alumina microspheres produced by our company are made by special process and are suitable for fluid and gas drying. The size of activated alumina microspheres can reach 14*28mesh, 0.5~1mm, etc. When drying fluids and gases, although all molecules will be absorbed by the activated alumina balls to a certain extent, their strong polarity allows them to selectively adsorb molecules. The pressure, concentration, molecular weight, temperature and other mixed gases of the gas affect the adsorption effect. The size of BR-101 is spherical Φ0.5-1, 1-2, 2-3, 3-5, 4-6, Φ5-7.
Product advantages:
Activated alumina microspheres are white in appearance, insoluble in water and organic solvents, and have hygroscopicity in the air. They have the characteristics of high activity, low wear, and good thermal stability.
This product is mainly used as a catalyst for melamine production and as a desiccant, adsorbent and catalyst carrier in other industries.
