Calcium chloride, also called calcium dichloride, is hygroscopic. It is white crystal, with forms of flake, granularity and power. As a salt of calcium and chlorine, calcium chloride behaves as a typical ionic halide, and is solid at room temperature. We provide anhydrous calcium chloride and its dehydrate, and we offer best quality, service and price.
Calcium chloride has a very high enthalpy change of solution. It can serve as a source of calcium ions in a solution. The exothermic dissolution of calcium chloride is used in self-heating cans and heating pads. For the hygroscopic property, calcium chloride is a desiccant. It is applied to keep a liquid layer on the surface of the roadway, which holds dust down. Adding solid calcium chloride to liquids can remove dissolved water.
By depressing the freezing point, calcium chloride is used to usually prevent ice formation and to deice. Calcium chloride dissolution is exothermic, and is relatively harmless to plants and soil. When distributed for this use, it usually takes the form of small, white balls a few millimeters in diameter. Solutions of calcium chloride can prevent freezing at temperature as low as −52 °C (−62 °F), making it ideal for filling agricultural implement tires as a liquid ballast, aiding traction in cold climates
As an ingredient, calcium chloride is listed as a permitted food additive in the European Union for use as a sequestrant and firming agent with the E number E509, and considered as generally recognized as safe (GRAS) by the U.S. Food and Drug Administration. The average intake of calcium chloride as food additives has been estimated to be 160–345 mg/day for individuals.
As a firming agent, calcium chloride is used in canned vegetables, in firming soybean curds into tofu and in producing a caviar substitute from vegetable or fruit juices It is commonly used as an electrolyte in sports drinks and other beverages, including bottled water. In addition, calcium chloride can be injected as intravenous therapy for the treatment of hypocalcaemia. It can be used for magnesium intoxication.
Calcium chloride is used in concrete mixes to help speed up the initial setting. The anhydrous form of calcium chloride may also be used for this purpose and can provide a measure of the moisture in concrete. Calcium chloride is used in swimming pool water as a pH buffer and to adjust the calcium hardness of the water.
Calcium chloride is included as an additive in plastics and in fire extinguishers, in wastewater treatment as a drainage aid, in blast furnaces as an additive to control scaffolding (clumping and adhesion of materials that prevent the furnace charge from descending), and in fabric softener as a thinner. In the oil industry, calcium chloride is used to increase the density of solids-free brines. It is also used to provide inhibition of swelling clays in the water phase of invert emulsion drilling fluids.
Because of its hygroscopic nature, anhydrous calcium chloride must be kept in tightly sealed, air-tight containers. Both anhydrous calcium chloride and dehydrate anhydrous calcium should be stored in cool, ventilated place, where they can be kept from water as well as the high temperature.
