Calcium chloride is a common inorganic salt that has many uses. Here are some application scenarios of calcium chloride:
1. Snow and ice removal: Calcium chloride can be used as a snow and ice remover for roads and pavements. It can dissolve snow and ice quickly and prevent ice from re-forming. In addition, compared with other snow-melting agents, calcium chloride is more environmentally friendly and will not cause corrosion to roads or vehicles.
2. Food processing: Calcium chloride is widely used in food processing, commonly used as coagulant, stabiliser, preservative and flavouring agent. For example, it can be used to produce tofu, cheese, candy and ice cream.
3. Drinking water treatment: Calcium chloride can be used in drinking water treatment, which can reduce the hardness and pH value of water, as well as remove iron and manganese in the water.
4. Recreational facilities: Calcium chloride can be used in swimming pool and spa water treatment, it can reduce the number of bacteria and other microorganisms in the water to ensure that the swimming pool and spa water is clean and safe.
5. Oil extraction: Calcium chloride can be used in the oil extraction industry as a treatment agent in drilling mud and as a suspending agent in cement slurry.
6. Pharmaceutical industry: Calcium chloride can be used in pharmaceutical products, for example, it can be used in the treatment of diseases such as hypocalcaemia, osteoporosis and depression.
In short, calcium chloride is used in many fields, including agriculture, chemical industry, pharmaceuticals, construction and so on.
