Rui Desheng Chemical FIG anhydrous calcium chloride food grade calcium chloride

Calcium chloride calciumchloridedihydrate Formula: CaCl2 · 2H2O calcium chloride nature: ice calcium. As colorless crystals. General merchandise is white, white or slightly yellow flakes or massive solid, bitter and astringent. Density 0.835g / cm3. Soluble in water, soluble in alcohol, insoluble in ether. Their solution was neutral or slightly alkaline. Corrosive. Heated to 260 ℃ dehydration into anhydrous. Deliquescence strong. Legal base of soda ash from ammonia production distillery waste (including calcium chloride 100g / L), after purification, clarification, evaporation, after the separation of sodium chloride, the mother liquor is clarified, continued concentrated calcium chloride content of 70% when cooling system. Hydrochloric acid and limestone powder can also be used in the reaction. As refrigerants, antifreeze, fire extinguishing agents, for melting ice and snow melt, manufacturing anhydrous calcium chloride, flame retardant cotton fabric, rubber production of condensate agent. Can accelerate hardening and increased tolerance to cold concrete construction mortar, but also used as anti-fogging agent port and road dust agent. From industrial grade saturated solution of calcium chloride dihydrate, adding bleaching agents, in addition to heavy metal agents, in addition to arsenic solution purification, filtration to remove impurities, liquid cooling and crystallization, solid-liquid separation
