Calcium chloride (chemical formula CaCl2) is the ionic compound of calcium and chlorine. It is a salt that behaves as a typical ionic halide, being solid at room temperature and highly soluble in water. Common applications include brine for refrigeration plants, ice and dust control on roads, and desiccation. Because of its hygroscopic nature, anhydrous calcium chloride must be kept in tightly sealed, airtight containers.
1).Used in highway, expressway, parking lot and port and as a dryer to dry nitrogen, oxygen, hydrogen, hydrogen chloride and sulfur dioxide etc.
2). Act as dehydration agent when producing alcohol, ester, ether and acrylic acid.
3). Calcium chloride is a kind of important cryogen used by freezing machine and when making ice.
4). It can increase hardness of concrete and increase cold resistance ability of the construction.
5). In port, acts as fog removing agent and dust collecting agent on road and fireproof agent of textile and acts as a protective agent and refining agent used in aluminum magnesium metallurgy.
6). Act as precipitator in producing lake paint. It is a kind of raw material of producing calcium salt. In algae sodium and bean industry it acts as flocculation.
