USD $899 - $899 /Metric Ton
Min.Order:1 Metric Ton
Activated alumina
Property:
1)epigranular
2)glossy surface
3)high mechanical strength
4)good hygroscopicity
5)keep its shape after absorbs water
6)non-toxic, tasteless, insoluble in water and organic soluble.
Appearance:white sphere
Use as a desiccant, it works by a process called adsorption. The water in the air actually sticks
to the alumina itself in between the tiny passages, as the air passes through them. The water
molecules become trapped so that the air is dried out as it passes through the filter. This process
is reversible, and if the alumina desiccant is heated to about 200°C it will release all of the water
stored in it.
Application
It can be used as desiccant and purificant in fertilizer or petrochemical industry. And also be used f
or the gas drying in oxygen making, textile industry and electronics.
