Activated alumina provides the following benefits in the batching of unqualified refractories:Improve billet density, fluidity, strength, secondary mullite generation, etc., and reduce water addition and porosity.In addition, activated alumina can also be used as adsorbent, desiccant, large water absorption, fast drying speed, can be regenerated (400 -500K baking) as well as the absorption of water does not swell, does not crack, does not deform.
Activated alumina is white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling or cracking after absorbing water to maintain the original state, non-toxic, odorless, insoluble in water, ethanol.It has strong adsorption of fluorine and is mainly used for defluoridation of drinking water in high fluorine areas.
Activated alumina has the ability to selectively adsorb gases, water vapor and moisture from certain liquids.After adsorption saturation, it can be regenerated by heating at about 175-315°C to remove water. Adsorption and recovery regeneration can be carried out several times.In addition to being used as a desiccant, it can also adsorb lubricant vapors from contaminated oxygen, hydrogen, carbon dioxide, and natural gas. It can also be used as catalyst and catalyst carrier and color layer analysis carrier.
It is widely used as catalyst and catalyst carrier in petrochemical and fertilizer industries.Modern water purification activated alumina and adsorption properties, and therefore used as a gas and liquid drying agent, gas purification adsorbent, drinking water fluoride removal agent, industrial sewage color and odor eliminator and so on.
It can be used together with household defluoridation cylinder, which is an ideal device for defluoridating drinking water in the family.This defluoridation filter media can also be used in conjunction with waterworks defluoridation devices or industrial defluoridation devices.Activation of defluoridation filter media of household defluoridation device: Configure aluminum sulfate solution (3 liters of water, 0.3 kg of solid aluminum sulfate), put alumina (AL2P3) defluoridation filter media into the above solution, soak it for 5-10 hours and discard the leaching solution (stirring appropriately during the soaking), and then wash it with water for 3-5 times, using 2 liters of water each time, or regenerate it by adjusting the PH method, and the pH value is controlled at 7.5. Activated alumina in addition to fluoride filter media can be used continuously for 6-8 years, when the surface appears yellow-brown, in addition to the fluoride effect is significantly reduced, this is due to impurities in the water contamination, so it is best to use 3% dilute hydrochloric acid every six months to deal with the same operation and regeneration methods.
Package specification:25kg/50kg/ton package, the product should be stored in indoor dry place.
Do not open the package before use, so as not to absorb moisture, affecting the effect of use.
