Product Details
1、active alumina desiccant
Activated alumina white spherical porous particles, particle size uniformity, smooth surface, high mechanical strength, strong moisture absorption, water absorption expansion does not crack after not intact, non-toxic, odorless, insoluble in water, ethanol.
Under certain operating conditions and regenerating conditions, drying and the depth of products up to dew point temperature of -70 degrees Celsius, can be used as high fluoride drinking water defluorinating agent (fluoride removal capacity), the defluorination of transformer oil, deacidification agent, used as oxygen industry, textile industry, electronic industry, dry gas recycling paraffins alkylbenzene production, automation instrument air drying, as well as in the chemical, petrochemical and drying industry as a desiccant, purifying agent (dew point can reach -40 degrees), in air separation industry pressure swing adsorption dew point of -55 degrees. Is a kind of high efficient desiccant drying micro water depth. Very suitable for no heat regeneration device.
Activated alumina ball desiccant (particle size can be processed in accordance with user requirements, from 1-12mm)
