Other Aspects Of Calcium Chloride

JIUXU INDUSTRIAL (HK) CO., LIMITED | Updated: May 02, 2018

The hydrated calcium chloride solid can be used as phase change energy storage material. For example, six calcium chloride can be used as an absorption and utilization of industrial waste heat recovery and solar radiation heat absorption as medium low temperature for industrial waste heat recovery and solar radiation, but it is similar to all inorganic hydrate phase change materials, because the six hydrate calcium chloride is 190 KJ/mol due to the melting point of 30, melting heat (i.e. the heat absorbed by the material from the solid phase to the same temperature). The serious problem of subcooling (its supercooling degree is 20 degrees C) needs to be overcome by adding nucleating agents.

Calcium chloride in concrete helps to speed up the initial setting effect, but chloride can cause corrosion of steel bars, so calcium chloride can not be used for reinforced concrete. Because of its hygroscopicity, anhydrous calcium chloride can provide a certain degree of moisture to concrete.

Calcium chloride is also an additive in plastic and fire extinguishers. In the waste water treatment as a filter aid, it is used as an additive in the blast furnace as an additive to control the aggregation and adhesion of raw materials to avoid furnace settlement, and to play the role of diluent in the softener of the fabric.
