desiccant is a white ball from 1mm-12mm.The product is a white, spherical porous material with the property of non-toxic, odorless, insoluble in water and ethanol. The particle size is uniform, the surface is smooth, the mechanical is strength, the ability of moisture absorption is strong and the ball is not split after absorbing water.In certain operating conditions and regeneration conditions, the dry depth can below the dew point temperature -70 degrees, the product can be used as defluorinate agent for high fluorided drinking water, as fluoride removal agent (fluoride removal capacity of large)for alkane cycling in the alkyl-benzene production ,as the depickling regeneration agent for transformer oil ,as the dryer for some industries such as oxygen industry, textile industry, gas drying in electronics industry ,air drying in automation instruments, as well as dryer and decontaminating agent for fertilizer, petrochemical and other industries (dew point can be up to -40 degrees), in air separation ,the dew-point adsorption of pressure change can up to -55 degrees. It is a high effective dryer for dry deeply in micro-water. It is an ideal dryer for non-thermal regeneration device.IndexUnitResultAL2O3%≥92SiO2%≤0.10Fe2O3%≤0.04Na2O%≤0.45loss on ignition%≤8.0Apparent densityg/ml0.62-0.68Specific surface aream2/g≥280Pore volumeml/g0.38-0.42Adsorption capacity(static state)%17±1Water absorption%≥50Crystalline phasex-p AL2O3Crushing strengthN/particle≥180 (5-7mm)
