How effective is calcium chloride desiccant in absorbing moisture? At Dingxing Desiccant, we learned that calcium chloride desiccant absorbs moisture from the surrounding environment and transforms it into a gel to achieve an adsorption effect, thus completely eliminating any possibility of leakage. Common desiccants can only absorb 10%-27% of their own weight. How effective is calcium chloride desiccant in absorbing moisture? Calcium chloride desiccant can reach 300%. The moisture absorption rate is 8-15 times that of ordinary desiccants. Therefore, calcium chloride desiccant has a strong moisture absorption effect and does not evaporate after completely absorbing moisture. It is widely used in moisture-proofing of shipping, containers, oil seals, optical medicine, health food and military products. Calcium chloride can react with water to generate CaCl2~2H2O, consuming water vapor in the environment. Calcium chloride desiccant has the functions of adsorption active static dehumidification and odor removal. Not only does it have fast adsorption speed and high adsorption capacity, it is also non-toxic, odorless, non-contact corrosive, non-environmental pollution, and especially non-harmful to the human body. Compared with silica gel desiccant, these two desiccants have very good moisture absorption effects. They are both neutral solid desiccants. Calcium chloride desiccant has a higher moisture absorption rate, while silica gel desiccant is cheaper.
