1. Versatile desiccant, such as for drying gases such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, etc. Used as a dehydrating agent in the production of alcohols, esters, ethers, and acrylic resins. Calcium chloride aqueous solution is an important refrigerant for refrigerator and ice making. It can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building Antifreeze. Used as a port defogger, road dust collector, and fabric fire retardant. Used as a protective agent and refining agent for aluminum magnesium metallurgy. It is a precipitant for producing lake pigments. Used for deinking waste paper processing. It is the raw material for producing calcium salts.
