What is the Principle of Calcium Chloride Being Used as a Desiccant?
The principle of calcium chloride as a desiccant primarily involves chemically reacting with water molecules to absorb moisture from the surrounding environment. Specifically, when calcium chloride desiccant comes into contact with moisture, it absorbs water from the humidity and undergoes a chemical reaction with the water molecules, converting them into a gel-like substance. This gel-like material can fully absorb several times its own weight in water, thereby removing moisture from the environment.
Calcium chloride desiccant exhibits an exceptionally high moisture absorption rate of approximately 300%, which is 8-15 times that of conventional desiccants. After absorbing moisture, it does not release the trapped water, maintains a stable absorption capacity, precents the formation of water droplets, and ensures sustained dryness over time.
Common application range of calcium chloride as a desiccant:
1. Place it in the cabinet where clothes are stored to absorb moisture in the air and keep clothes dry. It can also be placed in damp basements, garages, storage rooms and other places to prevent mold and bacteria from breeding.
2. Placed in food packaging, absorb the moisture in the packaging, and extend the shelf life of food. For example, it is used for the preservation of chocolate, cookies, candy and other foods.
3. Place the medicine or cosmetics in the packaging box to prevent the medicine or cosmetics from being spoiled by moisture.
4. Put in the packaging box of electronic products to prevent electrical appliances from being damaged by moisture.
