How and where is Calcium Chloride used?
Calcium chloride also widely popular as CaCl2, is nothing but an inorganic substance that is basically salt (chemical formula - CaCl2). At ambient temperature, it is a white crystalline solid that is readily soluble in water. It is made by neutralising hydrochloric acid with calcium hydroxide.
Calcium chloride is a hydrated solid that has the general formula CaCl2(H2O)x, where x can be any number between 0, 1, 2, 4, and 6. These chemicals are mostly used for deicing and dust management. The anhydrous salt is used as a desiccant since it is hygroscopic.
Palvi Chemicals is one of the most prominent Calcium Chloride suppliers in Nigeria.
Although non-toxic in small doses when wet, the
non-hydrated salt's very hygroscopic qualities pose considerable risks. Calcium
chloride can irritate moist skin by desiccating it. Consuming concentrated
solutions or solid goods may result in gastrointestinal irritation or ulcers.
Hypercalcemia can result from the consumption of calcium chloride.
Palvi Chemicals is one of the distinguished and noted Calcium Chloride exporters in Ghana.
Uses:
● Calcium chloride is used in
concrete mixes to speed up the initial setting time, however, chloride ions
cause steel rebar to corrode, hence it should not be used in reinforced
concrete. The anhydrous form of calcium chloride can also be employed for this
purpose and can provide a measurement of the moisture content of the concrete.
● Calcium chloride is used as
an additive in plastics and fire extinguishers, as an additive in blast
furnaces to control scaffolding, and is also present in the fabric softener as
a thinner.
● Calcium chloride exothermic
dissolution is utilised in self-heating cans and heating pads.
● The density of solids-free
brines can be improved via the use of calcium chloride in the oil industry.
It's also utilised to keep swelling clays at bay in the water phase of
inversion emulsion drilling fluids.
● CaCl2 works as a
flux material, lowering the melting point, in the Davy process, which is used
in the industrial manufacture of sodium metal via electrolysis of molten NaCl.
● CaCl2 is also utilised as a flux and electrolyte in the FFC Cambridge titanium manufacturing process, where it guarantees an adequate exchange of calcium and oxygen ions between the electrodes.
Palvi Chemicals is one of the most reputed Calcium Chloride suppliers in Nigeria.
● Calcium chloride is also used
to make activated charcoal.
● Calcium chloride, as
insoluble CaF2, can be used to precipitate fluoride ions from water.
● Calcium chloride is also a
component of ceramic slipware. It suspends clay particles in the solution,
allowing them to float, making it easier to employ in a number of slipcasting
procedures.
● As a sterilant for male
animals, calcium chloride dihydrate (20%) dissolved in ethanol (95% ABV) has
been employed. The solution is injected into the animal's testicles. Necrosis
of testicular tissue results in sterilisation within one month.
