Uses: anhydrous calcium chloride is widely used in the production of calcium chloride desiccant manufacturers, the solution is important refrigerants. The main purpose of gas, oil, organic solvents (such as alcohol, ether and the like) desiccant, preservative articles, oil drilling mud and completion fluid solid. The chemical industry for the manufacture of metal calcium, barium green, a variety of calcium. Chemical additives for paint pigments bgs calcium chloride manufacturers, construction industry as antifreeze, to accelerate into the concrete to harden and increase capacity building mortar cold anhydrous calcium chloride (CaCl2) is white or off-white solid (granular, block or powder), slightly bitter taste of the best manufacturers of calcium chloride, odorless, soluble in water and emit a lot of heat when dissolved in water. Has a strong hygroscopic, easily deliquescence in the air, should be confined storage. 1, made of calcium chloride dihydrate (CaCl2 · 2H2O): Hydrochloric acid (31%) and limestone powder, according to 2.2: 1 ratio into the reaction tank, reaction with stirring to produce an acidic solution of calcium chloride, into clarification tank. Milk of lime was added, the solution was adjusted pH value of 8.9 to 9, then ferric hydroxide, magnesium hydroxide precipitate. After clarification by filtration, the filtrate was moved in an evaporating dish and heated to 172 ~ 174 ℃ evaporated and purified by crystallization, separation after drying at 200 ~ 240 ℃ dehydration, to obtain the calcium chloride dihydrate. 2. Anhydrous calcium chloride: calcium chloride dihydrate will be reheated to 260 ~ 300 ℃, dehydration, i.e., changes to the white anhydrous calcium chloride.
