1, The existing form: anhydrous calcium chloride and calcium chloride dihydrate in accordance with the substance in the form of calcium chloride molecules to the classification. Calcium chloride dihydrate in the form of two crystalline water exist, the water content of the material is more than the amount of water High (this does not mean that its quality is not good, but a state of material existence).
2, Appearance: anhydrous calcium chloride is generally spherical diameter 2-6 mm, calcium chloride dihydrate is generally flaky, film thickness 1-2 mm. Color, such as high purity white, low purity corresponding low whiteness.
3,The net content: calcium chloride anhydrous calcium chloride net content of 90% or 94%, calcium chloride dihydrate in the net content of about 70%.
