Calcium chloride dihydrate appears as a white flake solid with the molecular formula CaCl2·2H2O. Its hygroscopicity is very strong, and it is easy to delix when exposed to air. Calcium chloride dihydrate is soluble in water, soluble in alcohol, acetone, acetic acid, while releasing a lot of heat, its aqueous solution is slightly alkaline. At low temperature, the solution crystallizes and precipitates as hexahydrate, which is gradually dissolved in its own crystalline water when heated to 30 degrees, and the water temperature will gradually lose water when heated to 200 degrees, and then becomes a dihydrate when heated to 260 degrees, it becomes a white porous anhydrous calcium chloride.
Calcium chloride dihydrate is mainly used as refrigerant, antifreeze, fire extinguishing agent, for ice melting and as snow melting agent, for manufacturing of anhydrous calcium chloride, as flame retardant of cotton fabric, condensate agent for rubber production. It can accelerate the hardening of concrete and increase the cold resistance of building mortar, and is also used as a port fogging agent and road dust collector. From industrial grade calcium chloride dihydrate saturated solution, adding decolorizing agent, removing heavy metal agent, removing arsenic agent for solution purification, filtration to remove impurities, filtrate cooling crystallization, solid liquid separation, drying can be prepared food grade products. It is used as a coagulant and calcium fortifying agent for cans and soybean products. It is used as calcium fortifying agent, chelating agent and curing agent in food industry.
The most common use of calcium chloride dihydrate on the market is as a snow melting agent. In winter, snow and ice is the “enemy” that hinders traffic, especially in recent years, due to the deteriorating environment and frequent disastrous weather, the current snow melting and deicing measures for highways, airport runways and other ground mainly include mechanical snow removal, artificial snow removal and snow melting agent snow removal. Mechanical snow removal is due to the lack of large snow removal equipment; The speed and efficiency of manual snow removal are low, which is easy to cause safety accidents, and the labor intensity is large, which affects the order and speed of traffic circulation. Snow melting agent snow removal can reduce snow labor costs, save expenses, but also can alleviate the snow on the road caused by traffic impact, with mechanical, artificial snow removal incomparable advantages, harmless to Bridges, airports, railways, sidewalks, green plants and public facilities, to minimize the impact of snow melting agent on the road and the environment and damage. The residual product of snowmelt can promote plant production, realize secondary utilization, and the product price is reasonable.
