Calcium chloride is an important chemical product. It is widely used in roads, oil drilling, industrial fields, mining fields, food industry and agriculture. Let's introduce the uses of calcium chloride in these six fields in detail:
1、 For road antifreeze, maintenance and dust control: calcium chloride is the best road snow melting agent, antifreeze and dustproof agent, and has a good maintenance effect on pavement and subgrade. A large amount of calcium chloride is used in Europe and America every year.
2、 For oil drilling: calcium chloride solution has a high density and contains a large amount of calcium ions. Therefore, as a drilling additive, it can lubricate and facilitate the removal of drilling mud. In addition, calcium chloride can be mixed with other substances as well sealing fluid in oil exploitation. These mixtures form a plug at the wellhead and can work for a long time.
3、 Used in industrial field: calcium chloride is widely used as desiccant in industrial field. It can dry industrial gases such as hydrogen, oxygen, hydrogen and sulfur dioxide. It can also be used as dehydrating agent for alcohol ester ether and acrylic resin: calcium chloride aqueous solution is an important refrigerant for refrigerator and ice making.
4、 For mining industry: calcium chloride is mainly used to produce a kind of surface active solution, which is sprayed on tunnels and mines to control the amount of dust, which can reduce the risk of mine operation. In addition, calcium chloride solution can also be sprayed on open-air coal seams to prevent freezing of coal seams.
5、 Used in food industry: calcium chloride can be added to drinking water or beverages as an additive to increase the content of substances and as a seasoning agent. In addition, it can also be used as a refrigerant and preservative for quick freezing of food.
6、 For agriculture: spray wheat with a certain concentration of calcium chloride solution, and the fruit can be preserved for a long time. In addition, calcium chloride can also be used as a feed additive.
