Calcium chloride is generally a solid of porous blocks, and desiccant is a water-removing agent that absorbs moisture from the atmosphere. Its drying principle is 1. Calcium chloride can physically or otherwise water in the air or otherwise. The molecules are adsorbed in their own structure to achieve the purpose of dehumidification, drying the gas. Principle 2, calcium chloride desiccant can also absorb water molecules in the air by chemical means, and change its chemical structure through chemical reaction, so that it will become another substance, so as to achieve the purpose of drying.
In summary, we can know that because calcium chloride is hygroscopic, calcium chloride can absorb water molecules in the air through chemical reaction or physical means, and it becomes crystalline calcium chloride, so that To achieve the purpose of drying.
