Weifang Rui Desheng Chemical Co., Ltd. (www.ruidesheng.com) is located in Weifang, Shandong Weifang Binhai Economic Development Zone, Contact: Liqing Jie Rui Desheng Chemical Co., Ltd. Weifang calcium a, industrial uses (1) refrigerants : calcium chloride solution, is an important industrial refrigeration refrigerant. Calcium chloride in the course of the manufacturer, due to absorption of moisture in the air to reduce the concentration of calcium, especially in open systems. In order to prevent the concentration of calcium chloride, calcium chloride manufacturers reduced, causing the freezing point temperature, it must be regularly measured with a hydrometer proportion of calcium chloride. If the concentration is reduced, should be added to maintain the appropriate concentration. Aqueous solution of calcium chloride is corrosive to equipment manufacturers Weifang calcium chloride, it should be noted when using. (2) drying agent: anhydrous calcium chloride is commonly used in industrial and laboratory desiccant for drying such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases, but not used to dry ethanol and ammonia (as they will react with calcium chloride to produce CaCl2 · 4C2H5OH and CaCl2 · 8NH3). Production of an alcohol, an ester, an ether and an acrylic resin is used as a dehydrating agent. (3) the production of raw material for a variety of other calcium: calcium metal used in the manufacture of inorganic industrial, barium chloride, a variety of calcium (as calcium phosphate, etc.) materials. Flake calcium chloride role and purpose: as refrigerants; antifreeze; melting ice or melting snow; cotton fabric finishing and finishing of flame retardants; wood preservatives; rubber production is used as condensing agent fold; mixing starch as the glue.
