Alumina ball

Descripción del producto

Summary

Alumina ball is a kind of with porous high dispersion of solid material, the main ingredients for alumina (equal to or more than *2%), products than the major, can greatly improve grinding efficiency and reduce the grinding time, save energy, reduce costs, and effectively increase the effective volume of the mill, thereby increasing the adding amount of grinding materials; products, high hardness, low wear, can greatly prolong the service life of the grinding body; product has high whiteness, not to affect the color of the grinding material.

Alumina ball use
In the petrochemical and chemical fertilizer industry, widely used as catalyst, catalyst carrier. Modern water purification activated alumina has adsorption characteristics, and thus used as a desiccant gas and liquid, gas purification adsorbent, drinking water, fluoride removal agent, industrial waste water color and odor elimination agent, etc..
Activated alumina ball can be used in matching with domestic cylinder, it is an ideal device for drinking water in the household. The fluoride removal filter material can also be matched with a tap water plant in addition to the fluorine removal device or the industrial use of fluoride removal device. Household defluoridation device removal, the activation of fluoride removal filter material: configuration of aluminium sulfate solution (3 liters of water and 0.3KG solid sulfate aluminum), alumina (AL2P3) except for fluoride removal filter material into the solution, soak ***0 hours abandoned to immersion (immersion to proper mixing), and then water washing **5 times, about 2 liters of water every time, or regenerated by a method of regulating pH, pH control at 7.5. Activated alumina fluoride filter material to continuous use **8 years, when the surface appeared brown, in addition to the effect of fluoride decreased significantly, the impurity in water caused by pollution, so the best every six months with 3% dilute hydrochloric acid treatment. The operation method and regeneration method.
Activated alumina ball as a catalyst carrier, the comparative surface area, static adsorption, pore size, Kong Rong these indicators have strict requirements, which is the soul index as a catalyst carrier. General is in wet flue gas desulphurization catalyst of potassium hydroxide and the diameter of the molecules of hydrogen oxidation, Mn is at around 0.4 nm, the diameter of the water molecules is probably 0.4 nm, activated alumina ball carrier of the micropore probably between **6 nm, so will catalyst solution into the dimensional space of the activated alumina ball is no problem.
