Calcium chloride can be used as a snow melting agent for snow melting and snowing in winter roads. Mixing calcium chloride with industrial salt or magnesium chloride in the required proportion can effectively remove road snow. After being dissolved in water, it can lower the freezing point of water and prevent two. Once frozen.
Used as an anti-fogging agent and pavement dust collector and fabric fireproofing agent for ports. Used as a protective agent and refining agent for aluminum-magnesium metallurgy. It is a precipitant for the production of lake pigments. Used for waste paper processing and deinking. It is a raw material for the production of calcium salts.
Because calcium chloride is highly hygroscopic, it should be stored in a cool, ventilated and dry warehouse. Packaging containers must be sealed to prevent moisture and should be stacked separately from deliquescent items.
The three major differences between anhydrous calcium chloride and calcium chloride dihydrate:
1. Form of existence: anhydrous calcium chloride and calcium chloride dihydrate are classified according to the form of calcium chloride molecules in the substance. Anhydrous calcium chloride is substantially free of water and has only a small amount of external moisture;
Each calcium chloride molecule in the calcium chloride dihydrate exists in the form of two crystal waters, and the water content in the substance is relatively high.
2. Appearance: anhydrous calcium chloride is generally spherical with a diameter of 2-6 mm. Calcium chloride dihydrate is generally in the form of a sheet with a thickness of 1-2 mm. The color is as high as white, and the purity is low, and the whiteness is lower.
3. Net content: The net content of calcium chloride in anhydrous calcium chloride is 90% or more, and the net content of calcium chloride in calcium chloride dihydrate is about 70%.
