Calcium chloride (CaCl2) is a chemical compound composed of calcium and chlorine. It is highly soluble in water, absorbs moisture highly, and is known as a moisturizer. This material must be stored in airtight and moisture-proof packages. CaCl2 is soluble in water, so it is used as a suitable source of calcium, in substitution reactions, and easily replaces another cation.
Applications of Calcium Chloride
Calcium chloride has many uses in the industry such as:
- Used in oil and gas drilling
- Melting ice and snow on roads
- Soil stabilization and control of dust and fine dust on roads and deserts
- Accelerates the clogging process in concrete
- Industrial processes such as plastics, calcium salt production, facilitation of wastewater treatment.
Physical and chemical properties
The compound is usually odorless white crystals with an octagonal (cubic) structure. Calcium chloride is a moisture absorber and is available in both dry and hydrated forms, but dihydrate and hexahydrate forms are very rare. Unlike other calcium compounds, this salt is highly soluble and can be used as a source of calcium ions. It is soluble in glycerin and when it is dissolved in a high concentration of glycerin, it forms a glass.
Its chemical formula is CaCl2
- Has a molecular weight of 110,978 grams per mole
- Has a boiling point of 1670 and a melting point of 782 degrees Celsius
Its solubility in water is about 0.745 g / ml at 20 ° C.
Its density is 2.15 at 68 degrees Fahrenheit
- Its boiling point is set at about 1600 ° C.
Application of calcium chloride in the drilling industry
Calcium chloride is widely used in drilling oil wells. Cacl2 is one of the weighting fluids in the production of water-based mud that can regulate the density of petroleum liquids and help to control pressure. This mineral compound causes oil well fluids to swell during drilling operations.
If this compound is used in drilling, it eliminates the damage caused by the formation of sludge. It is also easier to work with and dilute with water. It can also quench solid dust scattered in the environment during drilling.
Same as calcium chloride there are several chemicals that can be used in the drilling operation. These chemicals and minerals can perform various tasks in drilling operations. For example, gilsonite in the drilling industry is used for cementing, lost fluids control, and etc. Therefore, recognizing drilling fluids and selecting each of them according to the type of well, drilling method, type of formation and geological conditions is of special importance.
Calcium chloride in the concrete industry
Calcium chloride is first mixed with concrete water and then added to a mixture of sand and cement so that calcium chloride has an accelerating role in the construction of these concretes.
Calcium chloride in the dryer
Calcium chloride is used to cover drying pipes. This material is also used in industrial and domestic dehumidifiers to absorb air moisture. The moisture-absorbing properties of this compound have led to the use of calcium chloride as an aqueous layer on the surface of dirt roads, which ultimately creates a substrate that helps keep dust below the surface.
Calcium chloride in food
Calcium chloride is also known as an additive used in ice cream and frozen desserts. Calcium chloride is used as a firming agent in canned vegetables. Helps to process food products as well as increase the shelf life and strength of fruits and vegetables. It is also used to make cheeses. Oral calcium chloride is also used in the production of animal feed.
CaCl2 is used as a preservative in a variety of snacks, beverages, sports drinks, and special occasions.
This chloride not only prevents food spoilage but also provides essential mineral calcium and increases the quality of the food.
Calcium chloride usage in beverages
Calcium chloride is an approved substance for use in a variety of beverages and mineral water. Exercise drinks restore electrolytes lost through sweating during long-term exercise.
Calcium chloride is used to treat some burns and poisonings in the pharmaceutical industry.
Antifreeze and freezing point reducer (deicing)
Simultaneously with reducing the freezing point of water, calcium chloride is used to prevent water freezing, especially on road surfaces.
The dissolution of calcium chloride is calorific and this heat is relatively harmless to soil and plants.
It works better at low temperatures than sodium chloride.
Calcium chloride by preventing freezing at -52 degrees Celsius to fill agricultural tires
Used in cold places to create friction.
Swimming pools and aquariums
Calcium chloride is used to increase the hardness of pool water.
Increasing the concentration of calcium in water reduces the dissolution of calcium compounds needed in the concrete structure and thus reduces the erosion of concrete in the pool.
In marine aquariums, calcium chloride is used to provide the biological calcium needed by some aquatic animals (calcium carbonate in the shell), such as snails.
The advantage of using this substance is that it has the least effect on the acidity of water.
Dangers of calcium chloride
Calcium chloride poses serious health and safety risks. Eating it leads to burns in the mouth and throat, excessive thirst, vomiting, stomach pain, low blood pressure. It can also cause excessive dryness or dry skin. In cases of severe exposure, it can cause skin burns, heart problems, respiratory problems, and seizures. Wear a gown, gloves, and goggles when handling these materials due to the high risks.
Iranian calcium chloride Supplier
Because the cost of transporting and importing chemicals is so high, buying from companies in neighboring or nearby countries always brings great benefits to customers. TEAMchem Company is an Iranian supplier of calcium chloride. TEAM has been able to export the material to major countries such as Vietnam, Russia, Indonesia, Thailand, Kazakhstan, Pakistan, Malaysia, Iraq, and Turkey. Iran is a good option for buying chemicals due to its land border with many countries. The calcium chloride produced by this company is offered with a purity of 94-97% and is suitable for drilling and deicing.
