Product Description
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.
Molecular Formula: Al2O3 • nH2O (0
