Granular anhydrous calcium chloride can be used as drying agent for drying nitrogen, oxygen, hydrogen, and sulfur dioxide gases.
Calcium chloride, CaCl2, is a salt of calcium and chlorine.
It behaves as a typical ionic halide, and is solid at room temperature.
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, air-tight containers.
It's very important raw materials for de-ink of waste paper and calcium salt.
Calcium chloride injections are used as a medical treatment for a number of conditions.
Calcium chloride may also be used as an additive to swimming pools, fabric softeners and fire extinguishers.
It's also used as antifogging agent in harbors, dust collection agent of road surface, fire-proofing agent of fabrics, protective agent and fining agent of aluminum and magnesium metallurgy, precipitant for lake pigments, etc. It also can be used as dehydrating agent in producing alcohol, ester, ether and propylene resin.
Hydrotropic solution of calcium chloride is the important cryogen for refrigerator and ice making.
It is also a good anti-freeze agent and agglomerating agent in construction for concrete hardening and cold hardiness of sand mortar.
