Calcium Chloride

Product Description

Calcium chloride is a chemical substance composed of chlorine and calcium, the chemical formula is CaCl2, white or off-white, and there are granular, honeycomb, spherical, irregular particles, and powder.

The detailed application of calcium chloride early strength agent in building concrete, grouting cement material, grouting material admixture, etc.

Application

Calcium chloride is an antifreeze used in the process of road or house construction (construction industry) to protect roads or buildings. After calcium chloride is dissolved in water, it will fill the space between water molecules, so that at sub-zero temperatures, because the arrangement of water molecules can not freeze as usual, it can play a role in anti-freezing. In the process of road maintenance or building construction, the use of calcium chloride antifreeze can achieve normal construction in a low-temperature environment, and protect the walls, roofs, and foundations of roads and buildings from damage due to low temperatures.

The main function of calcium chloride hardening accelerating is to accelerate the hydration rate of cement and promote the development of early strength of concrete. It has both a strong drought function and an enhanced water reduction function.

Industrial uses of calcium chloride:

1, used as a multi-purpose desiccant, such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, and other gases drying. Used as a dehydrating agent in the production of alcohols, esters, ethers, and acrylic resins. Calcium chloride aqueous solution is an important refrigerant for chillers and ice making, which can accelerate the hardening of concrete and increase the cold resistance of building mortar and is an excellent building antifreeze. Used as a port fogging agent and road dust collector, fabric fire retardant. Used as a protective agent and refining agent for aluminum and magnesium metallurgy. It is a precipitating agent for the production of lake pigments. Used for deinking waste paper processing. It is a raw material for the production of calcium salts.

2, Chelating agent; Curing agent; Calcium fortifier; Refrigerating refrigerant; Desiccant; Anti-caking agent; Microbial suppressant; Pickling agent; Tissue improvers.

3, used as a desiccant, road dust collector, antifogging agent, fabric fire retardant, food preservative, and used in the manufacture of calcium salt

4, used as a lubricating oil additive

5, used as an analytical reagent

6, It is mainly used to treat tetany, urticaria, exudative edema, intestinal and ureteral colic, magnesium poisoning, and so on caused by decreased blood calcium

7, used in the food industry as a calcium fortifying agent, curing agent, chelating agent, and desiccant.

8, can increase the permeability of bacterial cell walls.

Other aspects:

Calcium chloride can help speed up the initial setting in concrete, but chloride ions can cause corrosion of steel bars, so calcium chloride cannot be used in reinforced concrete. Anhydrous calcium chloride can provide a certain degree of moisture to concrete because of its hygroscopic properties.

Calcium chloride is also an additive in plastics and fire extinguishers, as a filter aid in wastewater treatment, as an additive in blast furnaces to control the aggregation and adhesion of raw materials to avoid the settlement of the charge, and as a diluent in fabric softeners.

The dissolving and exothermic nature of calcium chloride makes it used in self-heating cans and heating pads.

In the petroleum industry, calcium chloride is used to increase the density of solid-free brine, and can also be added to the aqueous phase of emulsified drilling fluids to inhibit the expansion of clay. It is used as a flux to lower the melting point in the process of producing sodium metal by electrolytic melting of sodium chloride by the Davy process. When ceramics are made, calcium chloride is used as one of the material components, which will allow clay particles to be suspended in the solution, so that the clay particles are easier to use when grouting.
