Description

English name: calcium chloride

Calcium chloride
1,Colorless cube crystal.
2,Commonly is white porous form of block or graininess, honeycomb-like.

Molecular formula: CaCl2

Molecular weight: **0.*9

Physical character:

Colorless cube crystal. Commonly is white porous form of block or graininess, honeycomb-like. There is no bad smell, taste tiny saline. Melting point **2 centigrade, boiling point above ***0 centigrade,hygroscopic property is extremely strong, reveal at the air extremely easy to deliquescence , easy to dissolve in water, disengaging a large number of heat , whose aqueous solution assume tiny acidity at the same time. Dissolve in alcohol, acetone, acetic acid. Can operation with ammonia or alcohol , heat till *0 centigrade dissolves in self's crystal water, continue heating losing moisture content gradually , till **0 centigrade becomes two water thing, heat to **0 centigrade become white porous anhydrous calcium chloride

Toxicity and protection: Touch with the skin is able to arouse corrosion. When produce and convey, wear work clothes, wear gloves, wear long tube gluey boot. Pay attention to protect the skin.

Use: Be broad used as desiccant, such as desiccation nitrogen gas, oxygen, hydrogen etc. Be used as dehydration agent when produce alcohol, ester, aether and crylic acid resin. The calcium chloride aqueous solution is the freeze machine and makes the ice's importance refrigerant, able to accelerate the beton rigidification and increase the building sand slurry cold-resistant ability, is the excellent construction antifreeze. Be used as port fog dispersal agent and the road gather dust agent, the textile fireproofing agent. Be used as protect agent , refine agent of aluminium magnesium metallurgy. Be the precipitator of produce lake dyestuff. Be used for wastepaper machining take off ink, is the raw material to produce calcium salt. And be used as calcic strengthen agent , curing agent and drier in the food processing.

Packing and transportation:

Packing with inner lining polyethylene plastic bag plastic weave bag or fibreboard barrel or iron barrel package. Every barrel (sack) net weight *0 kg, there are obvious " moistureproof " sign on the package barrel (sack).

Should store up at ventilated , dry storehouse. The package container must airproof , protection against the tide. Abstain from store up with the deliquescence product. Pay attention to guard against rain and insolation in transport process. When load and unload must handle gently , to prevent from packing damage. When catch fire, use water, sand and any fire extinguisher to save.
