Activated alumina desiccant

Product introduction:
Activated alumina desiccant substance non-toxic, odorless, non-powdered, insoluble in water. White ball, strong ability to absorb water. Under certain operating conditions and regeneration conditions, the drying depth of desiccant is as high as the dew point temperature below -40℃, which is a kind of highly efficient desiccant with trace water depth drying. Desiccant is widely used in gas and liquid phase drying of petrochemical industry, used in textile industry, oxygen industry and automatic instrument wind drying, air separation industry pressure swing adsorption. Due to the high net heat of the single molecular adsorbent layer, it is very suitable for non-heat regeneration devices.

Notes:
1, do not open the package before use, so as not to absorb moisture and affect the use effect.
2, activated alumina is suitable for deep drying, the use of conditions with pressure greater than 5 kg/cm2 is appropriate.
3. After the desiccant is used for a certain period of time, the adsorption performance will gradually decline, and the adsorbed water should be removed by regeneration, so that the gas used in the regeneration operation can be used repeatedly (dry gas with lower or the same pressure than dry operation; Having a dry gas at a higher or the same temperature than when drying; Wet gas after heating up; Wet gas after decompression).

Packing and storage:
25kg/ bag (inner plastic bag, outer plastic film woven bag). This product is non-toxic, must be waterproof, moisture-proof, do not contact with oil or oil vapor.
