Activated alumina
Features: X - P type activated alumina ball, R - type activated alumina ball is a white spherical material with many capillary channels, and has high activity. It can be used as adsorbent, defluorination agent, desiccant and oxidant, as catalyst carrier.
Notice of use:
1, do not open the package before use, so as not to absorb moisture, and affect the use effect.
2, this series of products sealed packaging, must be stored in a dry place, waterproof, moisture-proof.
