looking for dihydrate calcium chloride for moisture absorber

calcium chloride,White crystal or lumps. Melting point 782 ℃, boiling point 1600 ℃, density 2.15 g/cm 3 (25 ℃).The solubility of calcium chloride in the water is very big, 0 ℃ to 59.5 grams 100 grams of water can dissolve calcium chloride, 100 ℃ dissolve 159 grams. Can form containing 1, 2, 4, 6 crystallization water hydrates, they exist temperature range is: CaCl2 • 6H2O under 29 ℃;CaCl2, 4 h2o, 29 ~ 45 ℃;CaCl2 • 2H2O, 45 ~ 175 ℃;CaCl2, H2O, above 200 ℃.It is soluble in ethanol, generate CaCl2,4C2H5OH, and ammonia, the formation of CaCl2, 8NH3.

Anhydrous calcium chloride is commonly used industrial and laboratory desiccant, but cannot be used to dry the ethanol and ammonia. Calcium chloride is easy deliquescence, can be used for labor road to dust elimination. The temperature of the mixture of CaCl2 • 6 h2o and ice can reach 54.9 ℃, used as a refrigerant. Also used for the cement antifreeze.

Calcium chloride is usually white, with air suction is heavy water produces chemical reaction, irreversible, and is not affected by temperature is normal in 8 to 90 degrees between water absorption effect is very good, general moisture absorption rate from 100% to 200% after absorbing water appearance change, specific performance is as follows:
One, a small amount of water absorption Outward appearance is not too big change, still for the block.
Second, continue to suction surface become moist and soft, to melt.
Third, continue to water absorption Into a liquid by damp patches, then completely dissolved by water.
