The
activated alumina is white sphere, odorless, tasteless, non-toxic,
insoluble in water and alcohol, regular in particle size, smooth at
surface, with high mechanical strength and strong absorption of
moisture, not expanding and cracking after absorbing water, original
shape kept.
As an effective concentrated drier for trace
moisture, its drying capability could reach to dew-point below 70 under
certain operating and recovering conditions. Widely used for drying in
electronic, textile and oxidizing industry, also as adsorbent in
air-grading industry (dew-point below-55). It’s especially suitable for
de-fluorinating agent of drinking water, a de-fluorinating agent of
cyclical alkane in alkyl benzenes production, ade acidifying regenerator
of transformer oil, and as dryer, purifying agent, catalyst and carrier
in chemical fertilizer, petrochemical industries.
