Applications
Calcium chloride 0AQ is applied in various ways, for instance:
1. Moisture absorption & desiccant
In closed packages, warehouses or containers, the product is used as a desiccant to prevent moisture build-up.
2. Construction
In concrete mixtures, calcium chloride accelerates the curing process, especially in colder conditions. It shortens the processing time of concrete.
3. Road Maintenance & Smoothness Control
As a de-icing agent, calcium chloride is more effective than sodium chloride, especially at low temperatures. It prevents ice formation and reduces dust buildup on unpaved roads.
4. Water Treatment
Calcium chloride increases calcium levels in swimming pools or is used at conditioning wastewater.
5. Industrial Processes & Refrigeration
It is used as a brine solution in refrigeration plants, as a drying agent in laboratories, and as an excipient in chemical syntheses.
