Calcium chloride comes in two types. There are calcium chloride dihydrate and anhydrous calcium chloride. These types differ in the water they contain. The products are available in powder, flakes, and granules. They come in two grades. One is industrial-grade and the other is food-grade.
Calcium chloride dihydrate is a kind of white flake or grey chemical. The main use of it in the market is as a snow-melting agent. We dry calcium chloride dihydrate at 200-300°C to remove water. This produces anhydrous calcium chloride, which is white and hard at room temperature. It is commonly used in brine used in refrigeration equipment, road ice-melting agents, and desiccants.
The main raw material of calcium chloride desiccant is calcium chloride. It is made from high-quality calcium carbonate and hydrochloric acid. It is refined by reaction synthesis, filtration, evaporation, drying, and other processes.
The data shows that the global calcium chloride desiccant market size will reach USD 310 million by 2030. Its compound annual growth rate is 3.3%.
Industrial Grade Calcium Chloride Uses
1、Calcium chloride has the characteristics of heat in contact with water and a low freezing point, which is used for snow and ice removal on roads, highways, car parks, and docks.
2、Calcium chloride strongly absorbs water. It is neutral and can dry many common gases, like nitrogen, oxygen, and hydrogen. It can also dry hydrogen chloride, sulfur dioxide, and other gases. But it can not dry ammonia and alcohol, easy to react.
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 freezer and ice-making chilling agent. Lower the freezing point of the solution. This will make the freezing point of water fall below zero. The freezing point of calcium chloride solution is -20 to -30 degrees Celsius.
5、It can accelerate the hardening of concrete and increase the cold resistance of building mortar; it is an excellent building antifreeze.
6、It is a dehydrating agent when producing alcohol, ester, ether, and acrylic resin.
7、It is used as a demisting agent for the harbor, dust collecting agent for road surfaces, and fire retardant for cotton fabric.
8、It is a protective and refining agent for aluminum and magnesium metallurgy.
9、It is the precipitating agent for producing color pigment.
10、It is used for deinking of waste paper.
11、Used as an analytical reagent.
12、It is used as an additive to lubricating oil.
13、It is the raw material for producing calcium salt.
14、Construction industry can be used as an adhesive and wood preservative. Description: Formation of adhesive lag in the building.
15、It removes SO42- in producing chloride, caustic soda, and inorganic fertilizer.
16、Agriculture can be used as a spraying agent to prevent dry and hot wind disease in wheat, salt soil conditioner, etc.
17, calcium chloride in the adsorption of dust reduces the amount of dust and has a significant effect.
18、In oilfield drilling, it can stabilize the mud layer at different depths. Lubricate the drilling and ensure the smooth running of the mining work. The selection of high-purity calcium chloride to make hole plugs plays a fixed role in oil wells.
19, adding calcium chloride to swimming pool water can make the pool water a pH buffer solution and increase the hardness of pool water, reducing the erosion of pool wall concrete.
20, the treatment of fluoride wastewater, sewage phosphate, mercury, lead, and copper heavy metals dissolved in water after the chlorine ions have a disinfectant effect.
21, Adding calcium chloride to marine aquarium water can increase its bio-available calcium. Mollusk and coelacanth breeders will use the calcium to form calcium carbonate shells.
22, do compound fertilizer with calcium chloride dihydrate powder; the role of compound fertilizer production is granulation with the use of calcium chloride viscosity to achieve the role of granulation.
Food grade calcium chloride use
1, Used as preservative and antiseptic for apples, bananas, and other fruits.
2, Used to improve the compound protein of wheat flour and calcium fortifier in food.
3, As a curing agent, it can be used in canned vegetables. It can also make soybean curd curing to form tofu. It can be used as a raw material for cooking molecular gastronomy by reacting with sodium alginate to make the surface of vegetable and fruit juices gelatinized to form caviar-like blobs.
4, for beer brewing, the lack of minerals in the beer brewing liquid will add food calcium chloride; because calcium ion is one of the most influential minerals in the beer brewing process, it will affect the acidity of the wort and the role of the yeast to play an impact. And food calcium chloride can bring sweetness to the brewed beer.
5, As an electrolyte added to sports or soft drinks, including bottled water. As calcium chloride has a very strong salty flavor, it can be used instead of salt in the production of pickled cucumber without increasing the effect of sodium content in food. The freezing point-lowering property of Calcium Chloride is used in caramel-filled chocolate bars to delay the freezing of the caramel.
