ISO14001 PH 9.3 74% CaCL2 Calcium Chloride White Flakes 25kg/Bag Calcium Chloride Dihydrate
Calcium chloride is a chemical consisting of chlorine and calcium. The chemical formula is CaCl2, which is slightly bitter.
It is a typical ionic halide, white at room temperature, hard fragments or particles.
Its common applications include brine for refrigeration equipment, road ice melting agents and desiccant.
Colorless cubic crystal, white or off-white, granular, honeycomb block, spheroid, irregular granular, powdered.
Slightly toxic, odorless, slightly bitter taste.
Extremely hygroscopic and easily deliquated when exposed to air.
It is easily soluble in water, and the solubility is 74.5g /100g water at 20℃. At the same time, a large amount of heat is released (the enthalpy of calcium chloride dissolution is -176.2cal/g), and its aqueous solution is neutral.

Used as a multi-purpose desiccant, such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases drying.
Used as dehydrating agent in the production of alcohols, esters, ethers and acrylics.
Calcium chloride aqueous solution is an important refrigerant for refrigerating machine and ice making. It can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building antifreeze agent.
Used as port antifogging agent and road dust collector, fabric fire retardant agent.
Used as a protective agent and refining agent for aluminum magnesium metallurgy.
It is a precipitator for the production of lake pigments.
Used for deinking waste paper processing.
It is the raw material for the production of calcium salts.
