Activated alumina available application:"
absorbent, dessicant, catalyst carrier,
Activated alumina advantage
1. a highly efficient adsorbent with large porosity and contact surface
2.Very stable physically and chemically, even in high temperature and corrosive environments
3. the specific surface is large.
4. strong for water, oxide, acetic acid, alkali etc.
5.The capacity is stable, and the absorbed fluorine is 6400g/cm3.
6.It has high strength, low abrasion, and it will not be soften in water, no expansion, no powdery, no crack.
