Calcium Chloride Desiccant Rod 1000g Container Desiccant Rod

Calcium chloride desiccant is a commonly used moisture-adsorbing material, often employed to absorb humidity from the air, achieving a dehumidifying effect. Its main principles can be summarized as follows:

1. Moisture absorption reaction: Calcium chloride has strong hydrophilicity. In humid air, it absorbs moisture from the surrounding environment, undergoing a hygroscopic reaction. This is because the structure of calcium chloride contains hydrates, which form compounds with environmental moisture, adsorbing water.

2. Moisture absorption capacity: As a desiccant, calcium chloride has a high moisture absorption capacity and can absorb humidity from the air until saturated. When calcium chloride reaches saturation, visible condensation or crystallization occurs. Therefore, gel starch and superabsorbent polymers are added to convert the absorbed water into a gel-like form, preventing liquid leakage.
