Key performance of desiccant mainly includes the following aspects:
Moisture absorption capacity: The main function of desiccant is to absorb moisture from the surrounding environment, so moisture absorption capacity is one of its most important performance indicators. Moisture absorption capacity can be measured by the moisture absorption of the desiccant, usually using relative humidity (RH) as an indicator, that is, the maximum percentage of humidity that the desiccant can absorb at a specific temperature.
Adsorption capacity: In addition to absorbing moisture, desiccant can also adsorb other gases or chemicals, such as harmful gases and odor molecules such as oxygen, nitrogen, and carbon dioxide.
Heat resistance: During use, desiccant may be affected by high temperature, so it is very important to have good heat resistance. Heat resistance refers to the fact that the desiccant will not lose its moisture absorption and adsorption capacity at high temperature.
Acid and alkali resistance: Desiccant may produce acid-base reaction while absorbing moisture, so its acid and alkali resistance is also very important. Acid and alkali resistance refers to the fact that the desiccant will not lose its moisture absorption and adsorption capacity in acid and alkali environment.
Chemical stability: The desiccant needs to remain stable in various environments and not react chemically with other substances.
Waterproofness: The desiccant needs to be able to remain effective in a humid environment and not be damaged by water.
Mold resistance: The desiccant needs to be able to effectively prevent mold growth and keep the environment clean.
