Activated Alumina Desiccant

详情

Yuanying activated alumina desiccant has advantages such as stable chemical properties, good adsorption capacity, high pressure-resistant, high wear-resistant, etc.
Widely used in petrochemical gas and liquid drying, food, oxygen industry, textile industry, electronic industry, air filter, air compressor and automated instrument drying.
Activated alumina desiccant is white spherical porous granules, surface smooth, uniform particle size, non-toxic, odorless, tasteless, insoluble in water, alcohol and organic solvents, but insoluble in acids and alkalis. It has strong moisture adsorption, does not burst after absorbing water, possesses big mechanical strength, specific surface area and pore volume.
Due to the unique porous bone structure, high specific surface area and in an unstable transition state, activated alumina desiccant has biggish activity, strong affinity with active ingredient. It has a number of capillary channels, its selective adsorption is not only determined by its micro-holes diameter size, but also according to the polarity of the adsorbed materials. Activated alumina desiccant has a strong affinity to water, acetic acid, alkali, etc., is a micro-water depth desiccant also is the adsorbent of polar molecules. Its monomolecular adsorption layer has high net heat quantity, is very suitable for non-heat regenerative device (pressure swing adsorption device), its dew point temperature is below **0 ℃ and is a highly efficient desiccant.
