Products introduction:
Activated alumina has much micro-paths, so the specific surface is large. It can be used as adsorbent, desiccant, defluorinating agent and catalyst carrier. It is also a kind of trace water desiccant and the pole-molecular adsorbent, according to the adsorbed molecular polarization, the attachment force is strong for water, oxide, acetic acid, alkali etc. Activated alumina is 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 propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the adsorbing pollution material, such as H2S, SO2, HF and paraffin in the water gas, especially in the drinking water defluorination.
Appearance:white sphere, no odor, insoluble in water and in the majority of organic solvents.
Property: micro-path, large specific surface, high strength, stronger capacity of absorbing, stable, no soften in water, no expansion and no crack.
2. Applications
As defluoriating agent, our product can be applied in defluorinating water device, which owes to its large specific surface. The power of removing fluorine is closely related with the PH value of water. When the PH is equal to 5.5, the power of absorption reaches the maximum. Hence, it can be widely used in water treatment, especially be using to combine with de-arsenic device.
