Calcium Chloride
Application Principle Of As Desiccant
Calcium chloride desiccant has a wide range of applications due to its good safety.
In terms of moisture absorption, calcium chloride desiccant has an excellent effect, which can effectively absorb moisture from the air and keep the environment dry. So, what is the principle of calcium chloride desiccant?
Firstly, calcium chloride is an inorganic salt with strong hygroscopicity. It can react chemically with water molecules to form hydrates of calcium chloride. This hydrate has strong hygroscopicity and can absorb moisture from the air, thereby keeping the environment dry.
Secondly, the principle of calcium chloride desiccant is based on the effects of physical adsorption and chemical adsorption. In terms of physical adsorption, the surface of calcium chloride desiccant has many micropores and micro cracks, which can adsorb water molecules in the air and attach them to the surface of the desiccant. In terms of chemical adsorption, calcium chloride can react with water molecules to form hydrates, thereby absorbing water.
In addition, calcium chloride desiccant can also absorb moisture through permeation. When moisture in the air comes into contact with the desiccant, water molecules will penetrate into the interior of the desiccant, be absorbed and fixed in the desiccant, keeping the air dry.
Overall, the principle of calcium chloride desiccant is based on its strong moisture absorption ability. It can absorb moisture from the air through physical adsorption, chemical adsorption, and permeation, keeping the environment dry. Therefore, calcium chloride desiccant has excellent moisture absorption properties and is widely used in various applications that require a dry environment, such as food packaging, drug storage, warehousing and transportation.
