alumina powder use for industry
1.good quality&cheap
2.white powder
3.ISO 9011-2000 certificated
4.trade many years
Alpha alumina is also used in surface treatment applications, careful control of physical properties allow its as a metal polish and buffer in addition to surface that require a specific finish.Active grades are used in the Our factory can supply the good quality molecular sieve activated powder .it's used for deeply dewatering .

Activated Alumina is non-toxic, insoluble in water and alcohol, high mechanical strength & strong adsorption of moisture.
Activated Alumina (sphere) A-AS-04
White sphere, odorless, tasteless, non-toxic, insoluble in water and alcohol, regular in particle size, smooth at surface, with high mechanical strength and strong adsorption of moisture, not expanding and cracking after adsorbing 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). Its especially suitable for atmospheric temperature recovering equipment. Also could be used as a de-fluorinating agent of drinking water, a de-fluorinating agent of cyclical alkane in alkyl benzenes production, a de-acidifying regenerator of transformer oil, and as a dryer, purifying agent, catalyst and carrier in chemical fertilizer, petrochemical industries.
