When it comes to alumina balls, many people are very unfamiliar. When they look at the pictures, some people always say that they are glutinous rice balls or thousands of white blood cells. People with intensive phobia are even more confused. Aluminum balls have the function of adsorption and are widely used in some petrochemical industries. What is this thing that looks like a dumpling? What are the ingredients? What are the uses in industry?
Introduction of Activated Alumina Balls
Activated alumina balls are white spherical porous particles with smooth surface, uniform particle size and high mechanical strength. It has strong hygroscopicity, and can maintain its original state without swelling or cracking after absorbing water, non-toxic and odorless, insoluble in water and ethanol, and has strong adsorption performance for fluorine. It can be used as a fluoride removal material for drinking water.
The use of Activated Alumina Balls
1. As a catalyst
Activated alumina balls are widely used in fertilizers, catalysts and catalyst carriers in the petrochemical industry. As for the selection criteria of carriers, in addition to specific surface area and surface activity, there are many indicators, including mechanical strength, chemical stability and different selectivity.
2. Fluorine removal performance
Alumina spheres have large surface area physical properties due to their porosity and high dispersibility, as well as good adsorption, drying, surface activity and stability, fluorine removal and other properties commonly required as catalyst supports in exhaust gas treatment. Ideal device for defluoridation of drinking water in households, defluoridation filter material for water plants, and supporting use of industrial defluorination devices.
3. Waste gas treatment
Alumina balls are one of the good supports for catalysts in exhaust gas treatment. Under the action of the gas with high specific surface area, the exhaust gas component to be treated can react with the active component supported on it, and its stable surface activity can provide a strong guarantee for the stability of the catalyst system. Activated alumina for modern water purification has adsorption properties, so it can be used as a gas-liquid desiccant, a gas purification adsorbent, a defluorinating agent for drinking water, a decolorizing and deodorizing agent for industrial sewage, etc.
Specifications of activated alumina balls
Each material has different specifications, and the activated alumina ball is no exception. Its specifications are 1-3mm, 3-5mm, 4-6mm, 5-7mm, 6-8mm, etc. The alumina regenerative ceramic ball has High strength and wear resistance. It has high thermal conductivity and heat capacity, and high heat storage efficiency; it has the advantages of good thermal stability and is not easy to crack when the temperature changes drastically.
