Product Description

Calcium chloride as inorganic compounds, a composed of chlorine and calcium salt, as a typical ionic halide. Character is white and hard fragments or particles. Bitter, tasteless. Calcium chloride has outstanding adsorption ability to ammonia stripping and low temperature, the ammonia adsorption separation has great application prospect. But as a result of calcium chloride is not easy to form stable porous materials, contact with the ammonia gas area is small, and easy expansion, the agglomeration in the process of adsorption, desorption, so make it difficult to put into practical application in this respect. Calcium chloride to bear on specific surface carrier, can greatly increase the contact area of calcium chloride and ammonia gas. Existing related studies have shown that calcium chloride will bear on molecular sieve, and preparation of the composite adsorbent has better than single adsorbent adsorption performance and stability. Calcium chloride, a composed of chlorine and calcium salt, chemical formula for CaCl2. It is a typical ionic halide, 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 deliquescence, so anhydrous calcium chloride must be sealed storage in the container. Calcium chloride and hydrate and solution in the food manufacturing, building materials, medicine and biology, and other aspects have important application value.

In biology and medicine study, calcium chloride is widely used in buffer needed for the preparation of biomedical experiments, such as for potassium channels in studying a complex new activator with CaCl preparation used for isolated oocytes ND96 reserve liquid; In the study of guanosine acyl cyclase C of the midbrain dopamine neurons function using CaCl to brain slice preparation experiment; In the study of bacteria and archaea to repel fluorine toxicity of fluorine concentration of RNA switch to 1 tendency when L CaCl markers in series experiment, etc.

Import the purpose gene receptor cells in the process, you can use the calcium chloride increase receptor cell membrane permeability, makes the plasmid more easily import, this method is by Stanford university geneticist at Stanley Norman Cohen found in the study of e. coli in 1972.

By intravenous injection of 10% calcium chloride solution can be used for the treatment of hypocalcemia, magnesium calcium chloride can also be used in the treatment of poisoning. Injection of calcium chloride solution can be found by ecg measurement against cardiac toxicity. In hyperkalemia caused under the condition of high concentration of serum potassium, calcium chloride can protect myocardium, the function of preventing arrhythmia. Calcium chloride as the hospital emergency room of the regular drug, can be used for quick treatment of calcium channel blockers poisoning (this drug poisoning by taking the prevention of heart disease, they produce side effects caused by sulfur) and poisoning caused by hydrofluoric acid, but the black widow spider bites the poisoning caused by no effective detoxification. Calcium chloride and sodium bromide injection in China by the state food and drug administration approved as water electrolyte regulating drug use.

desiccant

Granular calcium chloride anhydrous often used as a desiccant filling drying tube, with calcium chloride dried kelp (or kelp) can be used in the production of soda ash. Such as some of the domestic dehumidifier DampRid will use of calcium chloride to absorb the moisture in the air. Calcium chloride can be used as gas and organic liquid desiccant or dehydrating agent. Due to the calcium chloride is neutral, so it can dry, acidic or alkaline gas and organic liquid, but also in the laboratory for making small amounts of gases such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, carbon dioxide and nitrogen dioxide dry when the produced gas. But cannot be used for drying of ethanol and ammonia, because of ethanol and ammonia, respectively will react with calcium chloride to produce alcohol compound CaCl 4 choh and ammoniate CaCl · 8 nh. Anhydrous calcium chloride can be made into household products used as air moisture absorption agent, anhydrous calcium chloride as SAP has been approved by FDA for dressing first aid, its role is to ensure that the wound dry.

Will spread in calcium ShaShi Road surface, by using the moisture absorption of calcium in the condensed moisture in the air when air humidity is lower than the dew point to keep the road surface moist, to control the road dust kicked up.

Deicing agent and the cooling bath

Calcium chloride can reduce the freezing point of water, and the road with a calcium chloride hydrate can prevent freezing and deicing snow melt, but after melting salt water will destroy the soil and vegetation along the way and the deterioration of pavement concrete.

Calcium chloride solution can also employ cryogenic cooling bath when mixed with dry ice. Partial join the brine solution, will stick dry ice until system in the ice. Different kinds and concentration of salt solution can maintain stable cooling bath temperature will have difference. Common salt and calcium chloride as raw materials, by adjusting the concentration to obtain the required temperature, not only because the calcium chloride tap cheaply, and because the eutectic temperature of the calcium chloride solution (that is, the solution for the temperature of the formation of granular ice sand son) is quite low, can reach 51.0 ℃, which makes the adjustable temperature ranges from 0 ℃ to - 51 ℃. The method can in dewar can have heat preservation effect, also can be in the dewar bottle volume is limited and at the same time, need more salt solution using general plastic container to dress up the cooling bath, this kind of circumstance temperature to maintain relatively stable too.

The source of calcium ions

Swimming pool water adding calcium chloride can make the water pH buffer solution at the same time increase the water hardness, doing so can less concrete pool wall erosion. According to le chatelier's principle and the same ion effect, increase the water calcium ion concentration will slow is necessary for concrete structures of dissolved calcium compounds.

In the Marine aquarium water with biological calcium chloride could increase the water available calcium, aquarium in the breeding of mollusks and coelenterates can use it to form calcium carbonate shells. Although calcium hydroxide or calcium reactor can also achieve the same goal, but in contrast to join calcium chloride is the fastest way is also the smallest effect on the pH of the water.

food

As a kind of food ingredients and calcium chloride has much value the role of chelating agent and curing agent, it has been approved by the European Union to allow used as food additives, E coding for E509. Is 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 that per person per day 160 to 345 mg of calcium chloride food additives.

Calcium chloride as curing agent, 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. As the electrolyte is added to the sports drinks or some soft drinks including bottled water. Because calcium chloride itself has very strong salty instead of salt for pickles can be produced without increasing the effect of the food of sodium. 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, it affects the acidity of wort and have played the role of yeast. And calcium chloride can bring sweet to produce beer.

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) 190 KJ/mol, therefore, can be used in industry in low-temperature waste heat recovery, the absorption of solar radiation heat utilization, but it with all of the inorganic salt hydrate phase change materials are similar, too cold serious problems (20 ° C) its supercooling degree, adding nucleating agent may be added 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 the calcium chloride can not be used in reinforced concrete. Anhydrous calcium chloride because of its hygroscopicity can give concrete to provide 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 easy.
