1, physicochemical properties: Colorless cubic crystal, white or gray-white porous block or granular solids. Relative density 2.15, melting point 782 ℃, boiling point 1600 ℃ above, hygroscopicity is very strong, very easy to hygroscopic, soluble in water, at the same time release a lot of heat, odorless, taste slightly bitter, aqueous solution is slightly acidic, soluble in alcohol, propionic vinegar, acetic acid.
2, the product uses: is produces the color deposition pigment precipitation agent. Production of nitrogen, acetylene gas, hydrogen chloride, oxygen and other gases desiccant. When producing alcohol, ether, ester and acrylic resin as dehydrating agent, the aqueous solution is an important refrigerant for refrigerating machine and refrigeration. Can accelerate the hardening of concrete, increase the cold resistance of cement mortar, is an excellent antifreeze. Used as a protective agent for aluminum-magnesium metallurgy and a refining agent.
Flake Calcium chloride
1, physicochemical properties: Colorless crystal, this product is white, off-white crystallization. Taste bitter, hygroscopic strong. Relative density 0.835, soluble in water, its aqueous solution is neutral or slightly alkaline, corrosive, soluble in alcohol insoluble in ether, heated to 260 ℃ when dehydration into anhydrous. Other chemical properties are similar to anhydrous calcium chloride.
