Calcium content (CaCL2Purity) 94-97% of magnesium chloride and alkali metal (M g & Alkali Chloride): 3% other impurities; [Other, impurity] 1.00% [Max] water; [moisture] 80 [min] size [particle size] 30-40 mesh packing; 25 kg / bag, plastic woven anhydrous calcium chloride (CaCl2) is white or off-white solid (granular, lump or powder) calcium chloride dry, slightly bitter taste, odorless, Soluble in water, 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. Lime calcium chloride dihydrate was added, the solution was adjusted pH value of 8.9 to 9, then ferric hydroxide, magnesium hydroxide precipitate. After clarification calcium chloride, filtered and the filtrate shift in an evaporating dish and heated to 172 ~ 174 ℃ evaporated and purified by crystallization, separation after drying at 200 ~ 240 ℃ dehydration, to obtain 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.
