The main use of calcium chloride

The calcium chloride is commonly used in industrial and laboratory drying agent, such as for nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gas drying, but can not be used to dry ethanol and ammonia. In the production of alcohols, esters, ethers and the acrylic resin used as a dehydrating agent.

Industrial Use
Inorganic industry for the manufacture of metal calcium, barium, various calcium (as calcium phosphate, etc.) of the material. Construction industry as antifreeze, to accelerate concrete hardening and increased tolerance to cold building mortar. Microbial haploid breeding industry as a medium. Analytical chemistry for the determination of the carbon content of steel, blood glucose solution, serum phosphorus and serum alkaline phosphatase activity and so on. Magnesium metallurgy as protective agent, refining agent. Also used as a fire retardant fabric, harbor anti-fogging agent, road dust agents and food preservatives. Lake pigment production precipitant. For processing waste paper deinking. Calcium chloride solution is an important industrial refrigeration refrigerant. During use, due to absorption of moisture in the air to reduce the concentration. Especially in open systems. In order to prevent the concentration of calcium chloride reduced, causing freezing point temperature, it must be regularly measured by hydrometer proportion of calcium chloride. If the concentration is lowered, should be added to maintain the proper concentration. With the concentration of calcium chloride and change the solidification temperature, when the solution concentration of 29.9%, the calcium chloride brine minimum solidification temperature of -55 ℃; calcium chloride solution is corrosive to the equipment used should be noted. Genetic engineering used to produce competent cells.

Medical purposes
Calcium chloride can be used to reduce blood calcium caused tetany and colic, ureteral colic and so on.
Can be used for low calcium induced urticaria, exudative edema, itching of the skin.
For rescue magnesium poisoning.
For vitamin D deficiency rickets, osteomalacia, pregnant and lactating women calcium supplement.
