Many industrial products have a long service life, so how long can activated alumina balls last? Some people say it can be used for 1-2 years, some say it can be used for 7-8 years, and some say it can be used for 10 years. So how long can it be used? Below, the manufacturer of activated alumina will give you a brief introduction.

Activated alumina manufacturers believe that activated alumina balls are white spherical porous particles. Uniform particle size, smooth surface, high mechanical strength, strong moisture absorption, no expansion or cracking after water absorption. Non toxic and odorless, insoluble in water, ethanol has a strong adsorption effect on fluorine. Commonly used as catalysts, catalyst carriers, desiccants, adsorbents, defluoriners for drinking water, decolorizers and deodorizers for industrial wastewater, etc. Activated alumina balls are unopened or used and can be stored for a long time. Basically, it's not a problem to not get wet for 1-2 years.

Activated alumina manufacturers believe that the water absorption rate of activated alumina balls will decrease after being used in the machine for about 2 years. At this point, the activated alumina balls can be desorbed, regenerated, and reused. After regeneration, the service life will gradually shorten. The service life is more or less, with longer ones requiring 10 years.

Activated alumina manufacturers believe that the recycling method for activated alumina balls includes: preparing hydrochloric acid solution, cleaning the activated alumina balls with hydrochloric acid solution, calculating the required amount of aluminum sulfate based on fluoride content, and then preparing aluminum sulfate solution. The aluminum sulfate solution is the same as the activation solution, and the regenerated aluminum oxide defluorination agent is soaked in the above solution for 30 hours. When soaking, pour out the soaking solution and stir appropriately, then rinse with water 3-5 times. Alternatively, the pH value of the regenerated activated alumina can be controlled at 7.5 using the pH adjustment method. Due to the numerous pore structures on the surface of the activated alumina, the specific surface area is large, almost reaching 300m2/g. The developed pore structure gives it excellent adsorption performance.

Activated alumina manufacturers believe that activated alumina balls are white balls made by processing aluminum hydroxide powder into balls and then calcining them at high temperatures in a kiln, which are activated alumina balls or other crystalline activated alumina ball products. This method of producing activated alumina is called the Bayer process. Let me briefly introduce the process flow of Bayer process. The first process is the preparation of raw material slurry, which involves preparing a series of raw materials such as bauxite, limestone, and sodium chlorate solution in a certain proportion to produce raw material slurry ore with chemical composition and physical properties that meet the leaching composition. More importantly, there is a high demand for bauxite. Many provinces in China are covered by bauxite, and the bauxite that truly conforms to the Bayer process is concentrated in Guangxi.

Activated alumina manufacturers believe that activated alumina has the characteristics of high mechanical strength, low wear rate, and excellent thermal stability, and is also more widely used. It is mainly used as a catalyst carrier, and 65% of the uses of activated alumina are on catalyst carriers, such as oil purifiers for transformers; Due to the good adsorption properties of activated alumina balls, they should be stored in a dry, ventilated, and moisture-proof warehouse, and contact with oil or oil vapor is strictly prohibited.
