Application

As a kind of food ingredients, calcium chloride can act as the role of chelating agent and curing agent, it has been approved by the European Union to be used as food additives, E code being E509. It’s considered by the US food and drug administration as "Generally recognized as the substance is safe" (Generally recognized as safe, abbreviated as GRAS). It is estimated to be 160 to 345 mg of calcium chloride food additives for per person per day.

As curing agent, Calcium chloride can be used in canned vegetables. It can also make soybean curd curing form bean curd, and can be used as molecular cooking food raw material by reaction with sodium alginate gel formation on the surface of vegetables and fruit juices like caviar of the ball.It is added to the sports drinks or some soft drinks including bottled water as the electrolyte. Because calcium chloride itself has very strong salty, so it can be produced without increasing the effect of the food of sodium instead of salt for pickles. Calcium chloride can reduce the freezing point of the attribute in stuffed with caramel chocolate bar is used to delay the freeze of caramel.
In the absence of minerals will join in beer brewing liquid calcium chloride, because calcium is brewing in the process of one of the most influential sex minerals, and it affects the acidity of wort and have played the role of yeast. And calcium chloride can bring sweet to beer.

Industrial Grade Calcium chloride

Introduction

Calcium chloride, an inorganic compounds, which consists of chlorine and calcium salt, is a typical ionic halide. It’s white and hard fragments or particles. Slightly bitter, odourless. Calcium chloride has outstanding adsorption ability to ammonia stripping and low desorption temperature. The ammonia adsorption separation has great application prospect. But because it’s not easy for calcium chloride to form stable porous materials, its contact with the ammonia gas area is small, and it’s easy to expand and agglomerate in the process of adsorption, so make it’s difficult to put it into practical application in this respect. Putting calcium chloride on the specific surface carrier, we can greatly increase the contact area of calcium chloride and ammonia gas. Existing related studies have shown putting calcium chloride on the specific surface carrier, the composite adsorbent we get has better adsorption performance and stability than single adsorbent.
 

Calcium chloride, whose chemical formula is CaCl2, is a typical ionic halide. It’s white solid at room temperature. Its common applications include cooling equipment used in salt water, roads, melting agent and desiccant. Because it is liable to absorb moisture in the air and deliquesce, so the anhydrous calcium chloride must be sealed in the sealed container. Calcium chloride and its hydrate and solution have important application value in the food manufacturing, building materials, medicine and biology, and other aspects .

 

Colorless cubic crystal, white or gray, granular, honeycomb block, globular, irregular granular, powder. WeiDu, odourless, taste bitter. Hygroscopicity is extremely strong, extremely easy to deliquesce if exposed to the air. Soluble in water, release a large amount of heat at the same time (dissolving enthalpy of calcium chloride for 176.2 CAL/g), its aqueous solution is slightly alkaline. Soluble in alcohol, acetone, acetic acid. With ammonia and ethanol, respectively to generate CaCl2 · 8 nh3 and CaCl2 · 4 c2h5oh complex. Under the low temperature solution crystallization and precipitation of six water content, heating gradually to 30 ℃ is dissolved in the crystallization of the water itself, continue to heat water loss gradually, to 200 ℃ when become dihydrate, heated to 260 ℃, it turns to white vesicular anhydrous calcium chloride.

Application

 

Industrial Application
1,Used as a multipurpose desiccant, such as used to dry nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases. Used as dehydrating agent when producing alcohol, ester, ether and acrylic resin . Calcium chloride aqueous solution is an important refrigerant for the use of refrigerator and ice because it can accelerate the hardening of concrete and increase the building mortar’s cold resistant ability. It’s also a good building antifreeze which can be used for port of antifogging agent, road dust collection agent, and fabric fire retardant. It can also be used for aluminum magnesium metallurgy protectant, refining agent, the precipitation agent of Aluminum magnesium metallurgy production. In a addition, it is used in waste paper deinking processing. It’s the raw material of producing calcium salt.

Other aspects

 

Calcium chloride hydrate solid can be used as a phase change energy storage material. Such as calcium chloride hexahydrate, due to the melting point of 30 ℃, heat of fusion (that is, the material from the solid phase into with the temperature of the liquid in the process of absorption of heat) of 190 KJ/mol, therefore, it can be used in industry in low-temperature waste heat recovery, the absorption of solar radiation heat utilization. But it is similar with all of the inorganic salt hydrate phase change materials in that it’s too cold (20 °C) and this needs nucleating agent to overcome.

 

Calcium chloride in the concrete help to speed up the effect of initial setting, but the chloride ion would cause steel corrosion, so it can not be used in reinforced concrete. While Anhydrous calcium chloride, because of its hygroscopicity, can provide concrete with a certain degree of moisture.

 

Calcium chloride and additives in plastics and a fire extinguisher, in wastewater treatment as a filter aid, in the blast furnace as additives to control the aggregation and adhesion to avoid sedimentation in the charge of raw material, have the effect of diluent in fabric softener.

 

The nature of the calcium chloride solution heat canned make it used in the heating and heating MATS.

In the oil industry, calcium chloride is used to increase the density of solid free brine, also can add in water phase emulsion drilling fluid is used to restrain the expansion of the clay. As a method of flux in David electrolysis of molten sodium chloride as fluxing agent in the process of production of sodium metal have the effect of lower melting point. Production of ceramics will be one of calcium chloride as material composition, it can make the clay particles suspended in the solution, so during grouting clay particles with more ease.
