Uses of Calcium Chloride

Calcium chloride is divided into dihydrate calcium chloride and anhydrous calcium chloride according to the content of crystal water, and the shape is powdery, flaky and granular. Calcium chloride is divided into industrial grade calcium chloride and food grade calcium chloride according to grade. Dihydrate calcium chloride is a white flake or gray chemical, and the most common use of calcium chloride dihydrate in the market is as a snow melting agent. Calcium chloride dihydrate is dried and dehydrated at 200~300 °C to obtain anhydrous calcium chloride products, which are white, hard fragments or granules at room temperature. It is commonly used in brine used in refrigeration equipment and as road ice melting agents and desiccants.

Uses of industrial grade calcium chloride:
1. Calcium chloride has the characteristics of heat generation in contact with water and low freezing point, It is used for snow melting and de-icing of roads, highways, parking lots and docks.
2. Calcium chloride has the function of strong water absorption, because it is neutral, it can be used for the drying of most common gases, such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases. However, ammonia and alcohol cannot be dried, and reactions are easy to occur.
3. Calcium chloride is used as an additive in calcined cement, which can reduce the calcination temperature of cement clinker by about 40 degrees and improve the production capacity of the kiln.
4. Calcium chloride aqueous solution is an important refrigerant for freezers and ice making. Reduce the freezing point of the solution to reduce the freezing point of the water below zero, and the freezing point of the calcium chloride solution is -20-30 °C.
5. It can accelerate the hardening of concrete and increase the cold resistance of building mortar, and is an excellent building antifreeze.
6. Used as dehydrating agent in the production of alcohols, esters, ethers and acrylic resins.
7. Used as antifogging agent and pavement dust collector in ports, cotton fabric fire retardant.
8. Used as a protective agent and refining agent for aluminum-magnesium metallurgy.
9. It is a precipitant for the production of lake pigments.
10. Used for waste paper processing and deinking.
11. Used as an analytical reagent.
12. Used as lubricating oil additive.
13. It is the raw material for the production of calcium salt.
14. In the construction industry it can be used as an adhesive and wood preservative
15. It is used to remove SO42- in the production of chloride, caustic soda and inorganic fertilizer.
16. In agriculture, it can be used as a spraying agent and salt soil amendment for the prevention of dry heat and wind disease in wheat.
17. Calcium chloride has a significant effect on adsorbing dust and reducing dust volume.
18. In oilfield drilling, it can stabilize the mud layer at different depths and Lubricate drilling to ensure smooth mining work. The use of highly pure calcium chloride to make the hole plug plays a fixed role in the oil well.
19. Adding calcium chloride to swimming pool water can make the pool water become a pH buffer solution and increase the hardness of the pool water, which can reduce the erosion of the concrete of the pool wall.
20. Used to help to do treatment of fluorine-containing wastewater, phosphate, mercury, lead, copper, heavy metals in sewage, chloride ions dissolved in water have the effect of disinfection.
21. Adding calcium chloride to the water of the aquarium can increase the content of calcium available to aquatic organisms, and mollusks and coelenterates farmed in the aquarium will use it to form the shell of calcium carbonate.
22. Calcium chloride powder dihydrate for compound fertilizer, the role in compound fertilizer production is for granulation, and the viscosity of calcium chloride is used to achieve granulation.

Uses of food grade calcium chloride:
1. It is used as a preservative for apples, bananas and other fruits.
2. It is used for the improvement of wheat flour complex protein and calcium fortifier in food.
3. As a curing agent, it can be used for canned vegetables. It can also solidify soybean curds to form tofu, and can be used as a raw material for cooking molecular gastronomy to gelatinize the surface of vegetables and fruit juice by reacting with sodium alginate to form caviar-like balls.
4. For beer brewing, food grade calcium chloride will be added to the beer brewing liquid lacking in minerals, because calcium ions are one of the most influential minerals in the beer brewing process, which will affect the acidity of wort and affect the role of yeast. Moreover, food grade calcium chloride can bring sweetness to the brewed beer.
5. as electrolyte added to sports drinks or some soft drinks including bottled water. Because food grade calcium chloride itself has a very strong salty taste, it can be used instead of salt for the preparation of pickled cucumbers without increasing the effect of food sodium content. Food grade calcium chloride lowers freezing point and is used in caramel-filled chocolate bars to delay caramel freezing.
