1) Chemical name : Calcium Chloride 94%min
2) English title : Calcium chloride; anhydrous calcium
chloride; calcium chloride; calcium dichloridecalcium chloride anhydrous calcium chloride, anhydrous
3) Features :
Calcium chloride, CaCl2, is a common salt. It behaves as a typical ionic halide, and is solid at room temperature. It has several common applications such as brine for refrigeration plants, ice and dust control on roads, and in concrete. It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. Because of its hygroscopic nature, it must be kept in tightly-sealed containers. It is used to turn kelp into a solid.
4) Use:
1.Used in highway, expressway, parking lot and port. As dryer to dry nitrogen, oxygen, hydrogen, hydrogen chloride and sulfur dioxide.
2.Act as dehydration agent when producing alcohol, ester, aether and crylic acid.
3.Calcium chloride is a kind of important cryogen used by freezing machine and when making ice.
4.It can speeden hardness of concrete and increase cold resistance ability of construction sand pulop.
5.In port, act as fog removing agent and dust collecting agent on road and fireproof agent of textile. Protective agent and refining agent of aluminum magnesium metallurgy.
6.Act as precipitator in producing lake paint. It is a kind of raw material of producing calcium salt. In algae sodium and bean industry it acts as flecculation.
