1. Check whether it is activated alumina ball color, yellow;
2. See if the service life exceeds two years, if it exceeds two years, replace it as soon as possible;
3. It depends on whether the humidity of the processing air is too high, such as the humidity on the footnote is too high, and the activated alumina ball on the footnote may also be invalid;
4. Observe whether there is a significant fluorine content in the fluorine-containing water. If there is significant fluorine content, the activated alumina ball needs to be replaced.
Activated alumina balls are white spherical porous particles with average particle size, smooth surface, high mechanical strength, strong moisture absorption, and no expansion or cracks after water absorption.
Non-toxic, odorless, insoluble in water and ethanol. Under certain operating conditions and regeneration conditions, the drying depth of activated alumina can reach -70 degrees below the dew point temperature.
Activated alumina balls can be used as high-fluorine drinking water fluorinating agent (large capacity), recycling paraffin alkyl benzene to produce defluorinating agent, transformer oil acid regenerating agent, used as oxygen drying industry, textile industry, electronics industry, automation Instrument wind drying, chemical fertilizer and other industries, petrochemical drying and dehumidification, purification agent, in the air separation industry, the dew point pressure swing adsorption can reach 55 degrees. This product is a deep drying desiccant with trace water.
