- Construction and Road Maintenance: Calcium chloride is often used for dust control on unpaved roads and as a de-icing agent to melt ice on roads and sidewalks. Its hygroscopic nature helps it attract moisture, making it effective in these applications.
- Agriculture: It is used to improve soil structure and as a supplement in animal feed.
- Food Industry: Calcium chloride is used as a firming agent in canned vegetables and cheese production, and as a preservative in some food products.
- Chemical Industry: It is used as a drying agent in various chemical processes and as a reactant in the production of other chemicals.
- Water Treatment: Calcium chloride is used to increase the hardness of water in various water treatment processes.
- Oil and Gas Industry: It is used in drilling fluids to control the density and viscosity of the fluids.
Calcium Chloride 77%, 94%
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.
Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2·nH2O, where n = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and dust control. Because the anhydrous salt is hygroscopic and deliquescent, it is used as a desiccant.
Calcium chloride is commonly used in various industries due to its versatile properties. The percentages you mentioned, 77% and 94%, usually refer to the concentration of calcium chloride in a solution or the purity of the solid form.
