Activated carbon
Product introduction:
The activated alumina desiccant for air separation has many pores and strong affinity for water. Due to its unique skeleton structure, it has the characteristics of stable specific surface area, good compressive strength, low wear, appropriate pore structure and low impurity content. The activated alumina not only contains amorphous gel, but also contains the rigid skeleton structure formed by hydroxide crystals, so it is very stable and will not soften, swell or crack when immersed in water, Wear resistance and impact resistance. It has the characteristics of no softness, no expansion and no pulverization when soaked in water in the medium used, so it is widely used in gas-phase and liquid-phase drying in petrochemical industry, textile industry and air separation oxygen production industry.

matters needing attention:
1. Do not open the packing bag before use, for fear of moisture absorption, which will affect the use effect.
2. Activated alumina desiccant for air separation is an adsorbent with certain adsorptivity. It is strictly prohibited to contact with oil or oil vapor to avoid affecting the use effect.
3. After a certain period of use, the adsorption performance gradually decreases, and the adsorbed water should be removed by regeneration for repeated use.
