Product introduction: Calcium chloride is an inorganic salt, which can be divided into liquid and solid according to its form. Liquid calcium chloride is a colorless and transparent aqueous solution. Solid calcium chloride is a white crystal, which can be divided into Flaky, granular and powdery according to different shapes. Odorless, slightly bitter taste. The relative density is 2.15 (25℃). Melting point 782℃. Boiling point is above 1600℃. It is extremely hygroscopic and easily deliquescent when exposed to the air. It is easily soluble in water and emits a lot of heat at the same time. According to the different crystal water contained in solid calcium chloride, it can be divided into calcium chloride hexahydrate, calcium chloride dihydrate and anhydrous calcium chloride. Calcium chloride has the characteristics of dissolving and exothermic, the freezing point of the aqueous solution is low, and the moisture absorption is strong. It is widely used for deicing and melting snow in road squares.
