Calcium chloride Use

It is highly hygroscopic and is often used as a desiccant. Used as a multi-purpose desiccant, such as drying of nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases. Used as a dehydrating agent in the production of alcohols, esters, ethers and acrylic resins. Calcium chloride aqueous solution is an important refrigerant for refrigerators and ice making. It can accelerate the hardening of concrete and increase the cold resistance of building mortars. It is an excellent building antifreeze. Used as an anti-fogging agent in ports, dust collectors on roads, and fabric fire retardants. Used as protective agent and refining agent in aluminum-magnesium metallurgy. It is a precipitant for the production of lake pigments. Used for waste paper processing and deinking. It is the raw material for the production of calcium salt.
