Calcium chloride can be divided into calcium chloride dihydrate and anhydrous calcium chloride according to the crystal water contained. The shape of calcium chloride have powder, flake and granular form. And it can divided into industrial grade calcium chloride and food grade calcium chloride according to the grade. Calcium chloride dihydrate is a kind of white flake or gray chemical in the market of which the most biggest area is being sonw-melting agent. Anhydrous calcium chloride product can be prepared by drying and dewatering calcium chloride dihydrate at 200 ~ 300℃ and the color of annydrous one is white, hard solid under the normal tempreture. It is commonly used in salt water used in refrigeration equipment, road deicing agents and desiccant.

一、The Application of Industrial Garde Calcium Chloride

1. With the feature of heat and low freezing point in contact with water, industrial grade calcium chloride is used as snow and ice removal for 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. But can not dry ammonia and alcohol, beacuse it's easy to react with it.

3. Calcium chloride in calcined cement as an additive, can make the calcination temperature of cement clinker reduced by about 40 degrees, improve the production capacity of the kiln.

4. Calcium chloride aqueous solution is an important refrigerant for freezer and ice making. Reduce the freezing point of the solution, so that the freezing point of water is below zero, and the freezing point of calcium chloride solution is -20-30℃.

5. It can accelerate the hardening of concrete and increase the cold resistance of building mortar, and is an excellent building antifreeze agent.

6. It is used as dehydrating agent in the production of alcohols, esters, ethers and acrylic resins.

7. It used as port fogging agent and road dust collector, cotton fabric fire retardant flame retardant.

8. Used as a protective agent and refining agent for aluminum and magnesium metallurgy

9. It is a precipitating agent for the production of lake pigments.

10. Used for deinking waste paper processing.

11. Used as an analytical reagent.

12. Used as lubricant additive.

13. It is a raw material for the production of calcium salts.

14. It can be used as an adhesive and wood preservative in construction industrial.

15. It is used to remove SO42- in the production of chloride, caustic soda and inorganic fertilizers.

16. In agriculture, it can be used as spraying agent and salt soil amendment for preventing dry hot air disease in wheat.

17. It has remarkable effect in adsorbing dust and reducing the amount of dust.

18. In oil field drilling, it can stabilize mud layers at different depths. Lubricate the drilling to ensure the smooth progress of mining work. Calcium chloride with high purity is used to make hole plug, which plays a fixed role in 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. In the treatment of fluorine-containing wastewater and wastewater, phosphoric acid, mercury, lead and copper heavy metals, the chloride ions dissolved in water have the effect of disinfection.

21. Adding calcium chloride to the water of Marine aquariums increases the amount of bioavailable calcium in the water, and mollusks and coelintestinal animals raised in aquariums use it to form calcium carbonate shells.

二、The Application of Food Garde Calcium Chloride

1. Used as a preservative for apples, bananas and other fruits.

2. It is used to improve wheat flour complex protein and calcium enhancer in food.

3. As curing agent, can be used in canned vegetables. It also solidifies soy curds to form tofu, and can be used as an ingredient in molecular gastronomy by reacting with sodium alginate to form caviar-like pellets on the surface of vegetables and fruit juices.

4. For beer brewing, food calcium chloride is added to mineral-deficient beer brewing liquid, because calcium ion is one of the most influential minerals in the beer brewing process, it will affect the acidity of the wort and affect the role of yeast. And food calcium chloride can give the brewed beer sweetness.

5. Added as an electrolyte to sports drinks or some soft drinks including bottled water. Because the food calcium chloride itself has a very strong salty taste, it can replace salt for the production of pickled cucumbers without increasing the effect of sodium content of food. Food calcium chloride has a cryogenic property and is used to delay the freezing of caramel in chocolate bars filled with caramel.
