Product Introduction:
The appearance of activated alumina desiccant ball is white spherical with smooth surface, which has strong moisture absorption, and excellent stability. Moreover, activated alumina oxide has a large specific surface area and many capillary channels inside. It has strong adsorption capacity to strong molecular polar substances such as water, so it is one of the best raw materials for desiccant, which can absorb gas, water vapor, specific liquid and water. Compared with calcium chloride and silica gel, it can be said that it is a more effective moisture remover. After use, it can be regenerated by heating to 170 ° C ~ 300 ° C. The regeneration of adsorption can be repeated many times.

Application:
The net heat of the single molecule adsorption layer of activated alumina desiccant ball, it is very suitable for non-thermal regeneration devices. Under specific operating conditions and regeneration conditions, it can also be used as an effective desiccant for deep drying. It can be used in a wide range of fields, such as adsorption of air impurities, high-order purification of gas, desulfurization in petroleum products, and carrier in column chromatography.
Advantage:
Activated alumina ceramic balls are also determined according to the polarity of the adsorbed material. Activated alumina is a solid material with high porosity and high dispersion. It has a large specific surface area and has both good adsorption performance and good pressure, wear and heat resistance,
Precautions for the use of activated alumina desiccant ball:
(1) Do not open the package before use, so as not to absorb moisture and affect the use effect.
(2) This product is suitable for deep drying, and the pressure of use is more than 5 kg/cm2.
(3) After the product is used for a certain period of time, the adsorption performance will gradually decrease, and the adsorbed water should be removed by regeneration.
The gas for repeated use in regeneration operations should be:
① Dry gas with lower or the same pressure than the drying operation.
② Dry gas with a higher or the same temperature than the drying operation.
③ Wet gas after heating.
④ Decompressed wet gas.
