Product description:
Features:
colorless cubic crystal. white or white porous or grain, honeycomb. oderless, slightly bitter taste. Relative density of 2.15(25℃). melting point of 782℃, boiling point of 1600℃. strong moisture absorption. It is easy to deliquescent in the air. Easy to soluble in water and at the same time release lots of heat. It's water solution is slight acidity. soluble with alcohol, acetone and vinegar. React with ammonia and alcohol to produce CaCl2·8NH3 & CaCl2·4C2H5OH. Under the common temperature, crystal to produce Hexahydrate. add heat to 30℃ and it is soluble with self crystal water. Continously add heat, lose water, to 200℃ become dihydrate. Add heat to
260℃ it becomes water porous calcium chlorde,anhydrous.
Application:
1. For road antifreeze, maintenance and dust control, calcium chloride is the best road snowmelt, antifreeze and dust agent.
2. Used as a versatile desiccant, such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, etc.
3. Calcium chloride aqueous solution is an important refrigerant for freezer and ice making. It can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building antifreeze.
4.Used as desiccant, road dust collector, antifogging agent, fabric fire retardant, food preservative and for the manufacture of calcium salt.
5. Used as calcium intensifier, curing agent, chelating agent and desiccant in food industry.
6. As a drilling additive, it can lubricate and facilitate the removal of drilling mud.
7.Calcium ions can precipitate most anions.Chloride ions precipitate cations,and can also oxidize ions to purify wastewater.
