The activated alumina produced by our company has multi porous, high-strength X-P type alumina products with strong affinity for water, making it a desiccant for deep drying of trace amounts of water. It has the characteristics of not softening, expanding, or powdering when soaked in water in the medium, and is therefore widely used in gas-phase and liquid-phase drying in the petrochemical industry, textile industry, oxygen production industry, and automation instrument air drying.
Due to the good strength and wear resistance of our company's products, the net heating time of the single-molecule adsorption layer is high. So it is very suitable for non thermal reproduction devices. This product can also produce high-strength spherical particles with different diameters under different process conditions according to user requirements.
