By depressing the freezing point of water, calcium chloride is used to prevent ice formation and de-ice. More effective at lower temperatures than sodium chloride.
Calcium chloride is highly hygroscopic. It can be sprayed on road to prevent weathering, giving the road a wet appearance even in dry weather.
Calcium chloride solution has a high density and contains a large amount of calcium ions, as a drilling additive, it can play a role in lubricating and facilitating the extraction of drilling mud.
Calcium chloride can dry industrial gases such as nitrogen, oxygen, hydrogen, sulfur dioxide, etc. calcium chloride can also be used as a dehydrating agent for alcohols, esters, ethers and acrylic resins. Calcium chloride aqueous solution is an important refrigerant for refrigerators and ice making.
Calcium chloride is mainly used to produce a surface active solution, which is sprayed on the tunnel and in the mine to control dust and reduce the risk of mine operations. Calcium chloride solution can also be sprayed on the open cola seam to prevent freezing of the coal seam.
Calcium chloride can by used as an additive in drinking water or beverages to increase the mineral content and as a flavoring agent. It can also be used as a refrigerant and preservative for quick freezing of food.
