Activated alumina ball use time description
Many industrial products have a service life, so how long can activated alumina balls be used? Some people say it can be used for 1-2 years, others say it can be used for 7-8 years, and some people say it can be used for 10 years, so how long can it be used?
1. Activated alumina ball
Activated alumina ball is white and is a spherical porous particle. It has uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, and does not swell or crack after absorbing water. It is non-toxic, odorless, and insoluble. Water and ethanol have strong adsorption to fluorine. It is often used as catalyst, catalyst carrier, desiccant, adsorbent, fluoride removal agent for drinking water, color and odor elimination agent for industrial sewage, etc.
2. the shelf life of activated alumina balls
The activated alumina ball has not been opened or used, and it can be stored for a long time. Basically, if it is not wet for 1-2 years, there is no problem. The editor has already proved this with facts. There was a sample of activated alumina balls in the warehouse. It has been stored for a long time. It has been more than a year. The editor has used it as an experiment and found that it is basically not too close to the new product. The big gap.
3. the service life of activated alumina balls
Activated alumina balls in machine use are generally used for about 2 years, and the amount of water absorption will decrease. At this time, the activated alumina balls can be desorbed and regenerated, and they can be used again. After regeneration, the service life will gradually decrease. . The service life varies, the longest is 10 years. The editor finds that the strength of alumina balls is better and basically the use time is longer.
Regeneration and utilization method of activated alumina balls
Configure the hydrochloric acid solution, use the hydrochloric acid solution to clean the activated alumina balls, calculate the required aluminum sulfate mass according to the fluoride content, and then configure the aluminum sulfate solution. The aluminum sulfate solution is the same as the solution used for activation, and the regenerated alumina defluorinator is used Soak in the above solution for 30 hours, discard the soaking solution (stir properly when soaking), and then wash with water for 3-5 times. Or use the PH adjustment method to regenerate the PH and control it at 7.5.
