Product Description

 

Product Description

Activated Alumina Balls
White bead, non-toxic, odorless and insoluble in water and ethanol. According to different uses, its raw materials and preparation methods are different.

Application:
Used as desiccant to selectively adsorb water in some gases,vapors and liquids.
In addition to being used as a desiccant, it can also absorb the vapor of lubricating oil from contaminated oxygen, hydrogen, carbon dioxide,  etc.
Used as catalyst, catalyst carrier and chromatographic analysis carrier.
Used as adsorbents, water purifiers.

Factors that will affect the adsorption of Activated alumina balls
Particle size: The smaller the particle size, the higher the adsorption capacity, but the smaller the particle size, the lower the particle strength, affecting its service life.
PH value of raw water: When the PH value is greater than 5, the lower the PH value, the higher the adsorption capacity of activated alumina.
Raw water alkalinity: High bicarbonate concentration in raw water will reduce the adsorption capacity.
Chloride ion and sulfate ion.

Activated alumina has much micro-paths, so the specific surface is large. It can be used as absorbent desiccant and catalyst carrier. It is also a kind of trace water desiccant and the pole-molecular absorbent, according to the absorbed molecular polarization, the attachment force is strong for water, oxide, acetic acid, alkali etc..

Activated alumina defluorinated just as the anion exchange resin, but the selectivity is much strong. The defluorination effect of the actived alumina is good. The capacity is stable, the absorbed is 6400g/cm3. It has high strength, low abrasion, no soften in water, no expansion, no powdery, no crack.

It can widely used in the deep drying of cracked gas, ethylene and , hydrogen-generation, air separation, instrument air drying and  treatment for , also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the water gas, especially in the drinking water defluorination.
 

Molecular Formula:
Al₂O₃•n H₂O(0<N≤0.8)
