Activated alumina,
Activated Alumina,
Activated Alumina use exclusively in different industries for water absorbent. It is available in granules 2-6 mm in size & spheres / Balls 2-5 mm in size.
This product is a kind of alumina with special structure processed through a special process. It is non-toxic, odorless, odorless and white sand. It has high chemical purity, strong adsorption performance, fast solution transmission rate, and good decolorization effect. Easy regeneration, long service life and other characteristics, strong water absorption in the air, invariability after water absorption, drying at 110 °C can be restored, insoluble in water and organic solvents, soluble in strong acid and strong alkali solution at high temperature.
