activated alumina(Special for defluorination) is made by scientifically blending high-purity alumina and catalytic precision processing It can adsorb and remove harmful fluorine from water, and can be used for deoxygenation, defluorination, and arsenic removal in drinking water and industrial equipment Wastewater decolorization Deodorization, etc

Activated alumina balls are white spherical porous particles with uniform particle size, smooth surface, high mechanical strength, strong moisture absorption, and do not swell or crack after absorbing water. They are non-toxic, odorless, insoluble in water and ethanol, and have strong adsorption properties for fluorine; Baike activated alumina balls have many capillary channels and a large surface area, which can be used as adsorbents and desiccants. Its microporous surface possesses the characteristics required for catalytic activity, such as adsorption performance, surface activity, excellent thermal stability, etc., so it is widely used as a catalyst and catalyst carrier for chemical reactions. At the same time, it is determined based on the polarity of the adsorbed substance, which has strong affinity for water, oxides, acetic acid, alkali, etc. Activated alumina balls are a micro water deep desiccant and an adsorbent for adsorbing polar molecules.

Activated alumina ballsThe principle of fluoride removal is similar to that of anion exchange resin, but anion resin has a higher selectivity for fluoride ions. Activated alumina balls have good adsorption and defluorination effects, stable capacity, and absorb 6400 grams of fluoride per cubic meter of activated alumina. Activated alumina balls have high strength, low wear, no softening after immersion in water, no expansion, no pulverization, and no cracking. It can be widely used for deep drying and hydrogen production of petroleum cracking gas, ethylene propylene gas, air separation units, drying of instrument air dryers, and fluoride treatment in hydrogen peroxide. It can also remove pollutants such as sulfur gas, hydrogen, sulfur dioxide, hydrogen fluoride, and hydrocarbons from exhaust gas, especially suitable for defluorination treatment of fluorine-containing water.

Activated alumina has selective adsorption properties for gases, water vapor, and certain liquids' moisture. After adsorption saturation, it can be revived by heating at about 175-315 ℃ to remove water. Adsorption and resurrection can be performed multiple times. In addition to being used as a desiccant, it can also adsorb the vapor of lubricating oil from polluted oxygen, hydrogen, carbon dioxide, natural gas, etc.
Baike activated alumina balls are stored in the air, mainly exhibiting their dryness, water absorption, and ability to absorb moisture from the air. It has selective adsorption properties for gases such as sulfur, hydrogen, and sulfur dioxide in the air. After absorbing water, it does not affect its defluorination performance.
