Main applications
Industrial use
1, used as a multi-purpose desiccant, such as for nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases drying. It is used as dehydrating agent in the production of alcohol, ester, ether and acrylic resin. Calcium chloride aqueous solution is an important cooling agent for freezers and ice making, accelerates the hardening of concrete and increases the cold resistance of construction mortar, and is an excellent antifreeze agent for construction. It is used as anti-fogging agent for harbor, dust collecting agent for road surface and fireproofing agent for fabric. It is used as protective agent and refining agent for aluminum and magnesium metallurgy. It is the precipitating agent for producing color pigment. Used for deinking of waste paper. It is the raw material for producing calcium salt.
2, chelating agent; curing agent; calcium strengthening agent; refrigerant for refrigeration; desiccant; anticaking agent; anti-microbial agent; marinade agent; tissue improvement agent.
3, used as desiccant, road dust collector, anti-fogging agent, fabric fire retardant, food preservatives and used in the manufacture of calcium salts
4, used as lubricating oil additives
5, used as an analytical reagent
6, mainly used in the treatment of tetany, urticaria, oozing edema, intestinal and ureteral colic, magnesium poisoning, etc., caused by lowering of calcium
7, used in the food industry.
7, in the food industry as calcium fortifier, curing agent, chelating agent and desiccant.
8, can increase the permeability of bacterial cell wall .
Medical use
Indications:
1, the product can be used for intestinal colic and so on.
2, It can be used for pruritic skin diseases.
3, It is used to relieve magnesium salt poisoning.
4, used for vitamin D deficiency rickets, cartilage disease, pregnant and lactating women calcium salt supplementation.
5, the treatment of calcium deficiency, acute hypocalcemia, alkalosis and hypoparathyroidism caused by tetany, vitamin D deficiency;
6, allergic disorders;
7, magnesium toxicity rescue;
8, fluoride toxicity rescue;
9, cardiac resuscitation, such as hyperkalemia, hypocalcemia, or calcium channel blockade caused by abnormal cardiac function of the rescue.
10, calcium chloride solution can induce actin monomer polymerization, and the critical concentration of actin monomer polymerization and the concentration of calcium chloride solution is an inverse curvature function. The specific mechanism by which actin is induced to polymerize is related to the binding of calcium ions to several specific sites of the protein.
Extended information:
Calcium chloride hydrate solids can be utilized as phase change energy storage materials. For example, calcium chloride hexahydrate due to the melting point of 30 ° C, the heat of melting (that is, the material from the solid phase into the liquid phase of the same temperature in the process of the heat absorbed) reaches 190 KJ/mol, so it can be used as a low to medium temperature for industrial waste heat recovery, the absorption and utilization of heat from the sun, but it is similar to all of the inorganic hydrated salts of phase change materials, there is a serious problem of subcooling (its degree of subcooling of up to 20 ° C), the need to add nucleating agent to overcome. Add the addition of nucleating agents to overcome.
Calcium chloride has the effect of helping to speed up the initial setting in concrete, but chloride ions can cause corrosion of reinforcing steel, so calcium chloride cannot be used in reinforced concrete. Anhydrous calcium chloride can provide some degree of moisture to concrete due to its hygroscopic nature.
Calcium chloride is also used as an additive in plastics and fire extinguishers, as a filtration aid in wastewater treatment, as an additive in blast furnaces to control aggregation and adhesion of raw materials thus avoiding settling of the charge, and as a diluent in fabric softeners.
Calcium chloride's exothermic nature of dissolution makes it useful in self-heating cans and heating pads.
Calcium chloride is used in the petroleum industry to increase the density of unconsolidated brines, and can also be added to the aqueous phase of emulsified drilling fluids to inhibit the swelling of clays. It is used as a flux to lower the melting point in the electrolysis of molten sodium chloride to produce sodium metal by the Davy process. Calcium chloride is used as a material ingredient in the manufacture of ceramics, where it suspends the clay particles in solution, making it easier to use the clay particles when grouting.
