Hygroscopicity is extremely strong, extremely easy deliquescence exposed to the air.
Solubility: soluble in water, release a large amount of heat at the same time, its aqueous solution is slightly alkaline. Soluble in alcohol, acetone, acetic acid. With ammonia and ethanol, respectively to generate CaCl28NH3 and CaCl24C2H5OH complex. Under the low temperature solution crystallization and precipitation of six water content, heating gradually to 30 ℃ is dissolved in the crystallization of the water itself, continue to heat water loss gradually, to 200 ℃ when become dihydrate, heated to 260 ℃ was white vesicular anhydrous calcium chloride.
Calcium is also called the ice. Colorless crystals. General merchandise for white, gray or slightly yellow sheet or block solid, taste bitter and astringent. Density of 1.85 g/cm3 (20 ° C). Soluble in water, soluble in alcohol, insoluble in ether. Its aqueous solution is neutral or slightly alkaline. Is corrosive. When heated to 260 ℃ dehydration into anhydride. Deliquescence. By ammonia alkali distillation in the waste liquid of soda production of legal system (including calcium chloride 100 g/L), the purification, clarification, evaporation, after the separation of sodium chloride, the mother liquor clear, continue to concentrate, when calcium chloride content of 70%, cooling system. Reaction or use hydrochloric acid and limestone powder. Used as a coolant, antifreeze, fire extinguishing agent, used for snow and ice of molten, manufacture anhydrous calcium chloride, the cotton fabric flame retardant, rubber production of condensate agent. Can accelerate the hardening of concrete and increase the cold resistant ability building mortar, also serve as a port of the antifogging agent and road dust collection agent. By industrial water saturated solution of calcium chloride, to join the decoloring agent, in addition to heavy metal agent, arsenic removal agent solution purification, filtration to remove impurities, filtrate the cooling crystallization, solid-liquid separation, drying consumption level can be obtained from the product. Used for canned and concreting of soy products, calcium fortifier.
Product using:
1. used as a coolant, also used in food processing, pharmaceutical, etc
2. in the food industry as a calcium fortifier, chelating agent, curing agent, and frozen with refrigerant.
3. used as feed calcium supplement.
4. used as curing agent, the rules can be used in soy products according to production need to moderate.
5. used as a coolant (such as the freezer with frozen brine, ice making and ice cream with frozen brine), antifreeze, automotive antifreeze, fire extinguishing agent. Used for melting ice and snow melt, and fine finishing of cotton fabric flame retardant. Used as adhesive and wood preservatives. Raw material is made of anhydrous calcium chloride. Used in wall paint and plaster, increase ability of condensation. Rubber production as a condensation agent. Mixed starch paste used for gluing agent. Also used for smelting non-ferrous metal. Used for pharmaceuticals.
6. oxygen, sulfur sorbent. Food protective agent. Sizing agent. Water purifier. Antifreeze.
