?
1. White sphere, odorless, tasteless,non-toxic,insoluble in water and alcohol, with smooth?surface, high mechanical strength and strong adsorption of mositure,no expanding and?cracking after adsorbing water and can keep orginal shape.
?
2. Drying gas in electronic, textile and oxidizing industry
?
3. Drying of automation instrumentation
?
4. Be used as desiccant and depurant in fertilizer, petroleum industry
?
Activated alumina has much micro-paths, so the specific surface is large. It can be used as?absorbent?desiccant and catalyst carrier.?It is also a kind of trace water desiccant and the pole-molecular absorbent, according to the absorbed molecular polarization, the attachment force is strong for water, oxide, acetic acid, alkali etc.
