HẠT HÚT ẨM (DESICCANTAIR DRYER) Ứng dụng: Hạt hút ẩm dùng cho máy sấy khí Desiccant Model: DE-4-6MM Kích thước: 3-5 mm; 4 - 6 mm Trọng lượng: 25kg/bao

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 drierfor trace moisture, its drying capability could reach to dew-point below 70 under certain operating and recovering conditions. Widely usedfor drying in electronic, textile and oxidizing industry, also as adsorbent in air-grading industry (dew-point below-55). It’s especiallysuitablefor 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.
