1. Antifreeze: used in the process of road or house construction (construction industry) to protect the road surface or buildings.
2. Desiccant: Because calcium chloride reacts with water to produce hydrated calcium chloride, it has a strong binding force, so it has a good drying effect.
3. Refrigerant: The principle that calcium chloride can be used to refrigerate is an important refrigerant for freezers and ice makers.
4. Dehydrating agent: In the production of alcohol, ester, ether and acrylic resin, calcium chloride powder is used as a dehydrating agent.
5. Food industry: Calcium chloride is used as a flocculant for soybean products, and calcium chloride solution is used as a seaweed and sodium industry.
6. When it snows: It is used for snow and deicing of roads, highways, parking lots and docks.
7. Other uses: Calcium chloride is also used as road dust collector, fabric fire retardant, port fogging agent. In aluminum magnesium metallurgy, used as a protective agent, refining agent. Industrial grade calcium chloride is used to produce precipitating agent for color lake pigments, and is also used for deinking waste paper processing.
