Micro Activated Alumina Pellets For Removing Chemical Auxiliary Agent
Activated Alumina Balls For Fluorine & Arsenic Removal Chemical Auxiliary Agent
Products Introduction:
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 activated alumina is good. The capacity is stable, the absorbed fluorine is 6400g/cm3. It has high strength, low abrasion, no softening in water, no expansion, no powdery, no crack. It can widely be used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the water gas, especially in the drinking water defluorination.

Application
Activated Alumina is used by scientific deployment of high-purity alumina and catalytic made finishing. Adsorption of water it can remove harmful fluoride, can be used for potable water and plant oxygen, fluorine, arsenic removal. Effluent decolorization. Deodorization.
Activated alumina is mainly used as the adsorbent, water purifying agent, catalyst and catalyst carrier, according to different uses, and its raw materials and preparation methods are different.
Storage:
Avoid moisture, avoid scrolling, throw and sharp shocking during transportation, rainproof facilities should be readied.
It should be stored in dry and ventilated warehouse to prevent contamination or moisture.
