What is
Calcium Chloride desiccant?

Calcium chloride desiccant is a type of moisture-absorbing material that utilizes the hygroscopic properties of calcium chloride to control humidity and prevent moisture-related issues in various environments. It can be used as a multipurpose desiccant in the industrial field, such as for drying nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, and other similar compounds.

Similar to silica gel desiccant, when a calcium chloride desiccant becomes saturated with moisture, it can be regenerated by heating it to release the absorbed water, restoring its moisture-absorbing capacity for reuse.

What is the method for producing raw materials for Calcium Chloride desiccant?

method for producing Calcium Chloride Desiccant

Limestone Extraction

Obtain limestone or use brine from salt lakes, to source the primary precursor——calcium carbonate.

Solvay Process

Heat limestone to make quicklime or use the Solvay process to create soda ash and Calcium Chloride.

Hydration

Combine quicklime with water to produce slaked lime.

Calcium Chloride Formation

React slaked lime with hydrochloric acid to make Calcium Chloride solution.

Purification

Remove impurities from the solution.

Solidification

Evaporate or crystallize the solution to obtain solid Calcium Chloride.

Packaging

Package the final product for distribution and use as a desiccant.

What are the characteristics of Calcium Chloride desiccant?

  • High Hygroscopicity: Through chemical moisture absorption, calcium chloride has the capability to achieve a moisture absorption rate of up to 300% of its own weight.
  • Rapid Moisture Absorption: Calcium Chloride desiccants have a fast moisture absorption rate, making them suitable for situations where quick drying is necessary.
  • Non-Toxic and Safe: Calcium Chloride is generally considered safe for use, making it suitable for various applications,
  • Regenerability: Once saturated with moisture, it can be regenerated by heating.
  • Versatility: Calcium Chloride desiccants can be used in various industries
  • Compatibility: Calcium Chloride can be safely used with various products.
  • Long Shelf Life: When stored properly, Calcium Chloride desiccants have a long shelf life, retaining their effectiveness over time.
  • Environmental Impact: Calcium Chloride is less damaging to the environment compared to some other desiccants, making it a more sustainable choice in certain applications.
