Product Description

Product Description

Calcium chloride (chemical formula: CaCl2) is a white or slightly yellow solid inorganic compound. It belongs to the salt family and is a typical ionic halide. It is widely used in many fields due to its high solubility, hygroscopicity and dehydration. It exists in different physical forms according to its hydration form. The most common is dihydrate (CaCl2·2H2O). Its high solubility enables it to dissolve quickly in water and release a large amount of heat, making it very useful in applications that require rapid heating or drying. In addition, calcium chloride is also commonly used in brine used in refrigeration equipment, road deicing agents and desiccants.

Product use

Industrial Uses
1. Used as a multi-purpose desiccant, such as for drying gases such as nitrogen, oxygen, hydrogen, hydrogen chloride. Used as a dehydrating agent when producing alcohols, esters, ethers, and acrylic resins.
Food Uses
As a food ingredient, calcium chloride can act as a multivalent chelating agent and curing agent. It has been approved by the European Union as a food additive with an E code of E509. It is considered by the U.S. Food and Drug Administration to be a "substance generally recognized as safe."
Other Aspects
Hydrated calcium chloride solid can be used as a phase change energy storage material. For example, calcium chloride hexahydrate can be used as a medium-low temperature for industrial waste heat recovery and solar radiation heat absorption and utilization because its melting point is 30°C and its melting heat (i.e., the heat absorbed during the transformation of a substance from a solid phase to a liquid phase at the same temperature) reaches 190 kJ/mol. However, it is similar to all inorganic hydrated salt phase change materials in that it has a serious problem of supercooling (its supercooling degree reaches 20°C), which requires the addition of a nucleating agent to overcome it.
Calcium chloride helps to speed up the initial setting of concrete, but chloride ions can cause corrosion of steel bars, so calcium chloride cannot be used in reinforced concrete.
Calcium chloride is also an additive in plastics and fire extinguishers, as a filter aid in wastewater treatment, as an additive in blast furnaces to control the aggregation and adhesion of raw materials to avoid settling of furnace charges, and as a diluent in fabric softeners.
