Many industrial products have a long service life, so how long can activated alumina balls be used? Some people say that it can be used for 1-2 years, some people say that it can be used for 7-8 years, and some people say that it can be used for 10 years, so how long can it be used? The following activated alumina manufacturers give you a brief introduction. Activated alumina manufacturers think that activated alumina balls are white spherical porous particles.

Average particle size, smooth surface, high mechanical strength, strong hygroscopicity, no shrinkage or cracking after absorbing water. Non-toxic and tasteless, insoluble in water, ethanol has a strong adsorption effect on fluorine. Commonly used as catalyst, catalyst carrier, desiccant, adsorbent, defluorinating agent for drinking water, decolorizing and deodorizing agent for industrial sewage, etc. Activated alumina balls are unopened or used and can be stored for a long time. Basically, 1-2 years without getting wet is no problem.

Activated alumina manufacturers believe that activated alumina balls are generally used in the machine for about 2 years, and the water absorption rate will decrease. At this time, the activated alumina balls can be desorbed and regenerated for reuse. After regeneration, the service life will gradually shorten. The service life is more or less, long needs 10 years. Activated alumina manufacturers: some knowledge about activated alumina.

Activated alumina manufacturers believe that the recovery method of activated alumina balls includes: preparing a hydrochloric acid solution, washing the activated alumina balls with a hydrochloric acid solution, calculating the required mass of aluminum sulfate according to the fluoride content, and then preparing an aluminum sulfate solution. The aluminum sulfate solution is the same as the solution used for activation, and the regenerated alumina defluorination agent is put into the above solution to soak for 30 hours.
