Specification: COMMODITY: CALCIUM CHLORIDE 94-97% MIN PELLET (oil drilling chemical) APPEARANCE: WHITE PELLET CALCIUM CHLORIDE CONTENT 94-97%MIN SODIUM CHLORIDE 3.5%MAX CALCIUM HYDROXIDE 3.5%MAX WATER INSOLUBLE 0.2%MAXCas No.:10043-52-4; H.S. Code: 28272000.00 Calcium Chloride is a white deliquescent powder which is soluble in water and ethanol, with melting point at 782 C, boiling point at 1600 C and specific gravity of 2.15. Mono, Di and Hexahydrate forms are existing. But hexahydrate form loses 4H2O at room temperature. It is formed as a byproduct of the Solvay process, also called ammonia-soda process to make sodium carbonate from calcium carbonate and sodium chloride. It is also prepared by dissolving calcium carbonate or calcium oxide in hydrochloric acid. It is used chiefly for dust control on unpaved roads and as a roadway deicer. Other uses are waste water treatment, brine refrigeration systems, tire weighting, concrete acceleration and as a calcium source in chemical processing. Technical grade calcium chloride is produced with special attention to quality and consistency. Our ISO system ensures that our high standards are maintained and improved. Applications Technical grade calcium chloride is used in a multitude of applications within a wide variety of industries. It is used as: An agent for providing high density clear brine fluids in the oil industry. A precipitant for fluorides, sulphates, and phosphates in water purification. A safe, secondary cooling agent for hockey rinks and various construction projects. An additive in concrete to decrease setting time, especially in cold weather conditions. A dehumidifier and a desiccant in domestic and industrial applications. A calcium source in agriculture and animal feed. Applications Food grade calcium chloride is used in various applications within the food, beverage and pharmaceutical industries. Some examples of common applications are listed below. In the production of beer and soft drinks, CaCl2 is used as a source of calcium to regulate the hardness of water. In enzyme production, the calcium ion acts as a co-factor in some products. In the production of cheese, CaCl2 is used as a source of calcium. CaCl2 is also used to increase the firmness of canned fruits and pickled vegetables. CaCl2 is also used as a secondary cooling agent in various processes that operate according to food regulations.
