Quantity: 25Kilograms Specs:High-class goods Price:2.0 RMB Kilograms Payment Method: Payment to delivery Content of calcium chloride First, calcium chloride products, Calcium, Chloride, calcium chloride, chemical formula CaCl2, white powder, granular, flake, lump. Melting point 782 DEG C, boiling point 1600 DEG C, density 2.15 g / cm 3 (25 DEG C). The solubility of calcium chloride in water is very large. At 0 degrees centigrade, 100 grams of water can dissolve 59.5 grams of calcium chloride and dissolve 159 grams at 100 degrees centigrade. Can be formed with 1, 2, 4, 6 crystal water hydrate, temperature range of their existence is: CaCl2 - 6H2O is lower than 29 DEG C; CaCl2 - 4H2O, 29 ~ 45 DEG C; CaCl2 - 2H2O, 45 ~ 175 DEG C; CaCl2 - H2O, 200 DEG C. It is also soluble in ethanol and produces CaCl2 • 4C2H5OH, which acts with ammonia to form CaCl2 • 8NH3. Anhydrous calcium chloride is a common drying agent in industry and laboratory, but it can not be used for drying ethanol and ammonia. Calcium chloride is deliquescent, can be used for watering road to dust. The industrial calcium chloride is divided into solid calcium chloride and liquid calcium chloride. Solid calcium chloride is white or grey white or slightly yellow, red powder, flake, block or granular solid; liquid calcium chloride is a transparent liquid colorless or slightly turbid. Molecular formula: calcium chloride anhydrous calcium chloride CaCl2 two water calcium chloride CaCl2 - 2H2O CaCl2 - nH2O hydrated calcium chloride calcium chloride anhydrous calcium chloride molecular weight: 111.98 (according to the 2007 international relative atomic mass) of calcium chloride two water 147.01 (according to the 2007 international relative atomic mass) two, calcium chloride 1, Hunan Road, highway, parking lot, airports, golf courses and other winter snow; 2, oil drilling, drilling fluid and completion fluid, petroleum chemical dewatering liquid; 3, dust control, dust and dust; 4, the construction industry early strength agent, improve the strength of concrete, the production of paint coagulant; 5, for moisture-proof desiccant; dry gas and liquid media in the process; 6, coagulant latex in rubber industry; 7, ferrous metallurgy industry chlorinating agent and additives; 8, paper-making industry additive and waste paper 9, the industrial chemical deinking; inorganic chemical raw materials and sulfate removal agent, sodium alginate coagulant; 10, the refrigeration industry for cooling; 11, for control of wheat, apple, cabbage and rotten food preservative; 12, used in dyes and dyeing industry.
