Activated alumina ball introduce
Also known as modern water purification activated alumina, the English name is Activated Alumina or Reactive alumina; activated alumin(I)um oxide. The use of alumina (AL2O3) in the catalyst is usually called activated alumina. It is a porous, high-dispersion solid material with a large surface area, and its microporous surface has the characteristics required for catalysis. Such as adsorption performance, fluorine removal performance, drying performance, surface activity, excellent thermal stability, etc., so it is widely used as a household desiccant and a catalyst and catalyst carrier for chemical reactions.High-performance modern water activated alumina
High-performance modern water purification activated alumina can bring the following benefits in the unshaped refractory ingredients: increase the density, fluidity, strength of the green body, increase the amount of secondary mullite, etc., and reduce the amount of water and porosity. In addition, activated alumina can also be used as an adsorbent and desiccant. It has large water absorption, fast drying speed, can be regenerated (400-500K baking) and does not swell, crack, or deform after absorbing water.Modern water purification activated alumina
Modern water purification activated alumina is white spherical porous particles with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, does not swell or crack after absorbing water, and remains intact. It is non-toxic, odorless, insoluble in water, ethanol, and resistant to fluorine. It has strong adsorptivity and is mainly used for defluoridation of drinking water in high fluoride areas.Modern water purification activated alumina has selective adsorption capacity for gas, water vapor and some liquid moisture. After the adsorption is saturated, it can be heated at about 175-315°C to remove water to restore and regenerate. Adsorption and recovery regeneration can be carried out many times. In addition to being used as a desiccant, it can also absorb the vapor of lubricating oil from polluted oxygen, hydrogen, carbon dioxide, natural gas, etc. It can also be used as a catalyst and a catalyst carrier and a chromatographic analysis carrier.
Activated alumina ball product Usage
In the petrochemical industry and fertilizer industry, it is widely used as a catalyst and catalyst carrier. Modern water purification activated alumina has adsorption characteristics, so it is used as a desiccant for gas and liquid, an adsorbent for gas purification, a defluorinating agent for drinking water, and a color and odor elimination agent for industrial sewage.It can be used in conjunction with a household fluoride removal tank, and it is an ideal drinking water fluoride removal device in the family. The fluorine removal filter material can also be used in conjunction with the fluoride removal device of a water plant or an industrial fluoride removal device. Activation of fluoride removal filter material for household fluoride removal device: configure aluminum sulfate solution (3 liters of water, 0.3kg solid aluminum sulfate), put alumina (AL2P3) fluoride removal filter material into the above solution, soak for 5-10 hours and discard it. Liquid (stir properly when soaking), and then wash with clean water 3-5 times, each time about 2 liters of water, or use the PH adjustment method to regenerate, the PH value is controlled at 7.5. Activated alumina fluoride removal filter media can be used continuously for 6-8 years. When the surface appears yellowish brown, the fluorine removal effect is significantly reduced. This is caused by impurity pollution in the water. Therefore, it is best to treat it with 3% dilute hydrochloric acid every six months. The operation method is the same as the regeneration method.
