Activated Alumina Ball is also known as modern activated bauxite for water purification. Alumina is a kind of porous and highly dispersed solid material with large surface area. Its microporous surface has the characteristics required by catalytic action, such as adsorption performance, defluorination performance, drying performance, surface activity and excellent thermal stability, so it is widely used It is used as a domestic desiccant and as a catalyst and catalyst carrier for chemical reactions
Introduction of Activated Alumina Ball
Modern water purification activated alumina with high performance can bring the following benefits in the raw materials proportioning: improving the density, fluidity and strength of the green body, increasing the secondary mullite production, and reducing the amount of water added and porosity. In addition, activated alumina can also be used as adsorbent and desiccant, with large water absorption, fast drying speed, regeneration (baking at 400-500k) and water absorption without expansion, cracking and deformation.
Appearance of Activated Alumina Ball
Modern water purification activated alumina is a white spherical porous particle with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, and does not swell and crack after absorbing water. It is non-toxic, odorless, insoluble in water and ethanol. It has strong adsorption of fluorine, and is mainly used for defluorination of drinking water in high fluorine areas.
Modern water purification activated alumina has selective adsorption ability to gas, water vapor and some liquid moisture. After the adsorption is saturated, the water can be removed by heating at about 175-315 ℃ to recover and regenerate. Adsorption and recovery regeneration can be carried out many times. In addition to being used as desiccant, it can also absorb the vapor of lubricating oil from polluted oxygen, hydrogen, carbon dioxide and natural gas. It can be used as catalyst, catalyst carrier and chromatographic analysis carrier.
