Calcium Chloride

　　Product Characteristics:

　　Calcium chloride is commonly a white powder, flake, or granular solid. It  has extremely strong hygroscopicity and tends to deliquesce into a liquid when  exposed to air. It is highly soluble in water, releasing a large amount of heat  during dissolution, and can also be dissolved in organic solvents such as  ethanol and acetone. At room temperature, it has stable chemical properties and  does not react with oxygen, nitrogen, or other substances. However, at high  temperatures, it can undergo double decomposition reactions with certain metal  oxides or salts. Its aqueous solution is neutral to slightly acidic, with a pH  of approximately 6.5-8.5 due to the weak hydrolysis of calcium ions. The aqueous  solution has a low freezing point and is often used in the preparation of  antifreeze.

　　Technical Data(Executive Standard :FCC&USP41&ACS )

　　Applications:

　　Industrial Field

　　1. Desiccant and moisture-proof agent

　　2. Snow-melting and de-icing agent

　　3. Dehydrating agent in oil extraction

　　4. Added to concrete as an early strength agent to accelerate cement  hardening and improve early strength, especially suitable for winter  construction. The dosage must be controlled to avoid concrete cracking due to  excess.

　　5. Flux in the refining of metals such as copper and aluminum to lower the  melting temperature and improve metal purity; used as a desulfurizing agent in  the iron and steel industry to remove sulfur impurities from molten iron.

　　Agricultural and Food Fields

　　1. Soil improvement: Regulates soil pH, increases calcium ion content in  soil, improves the structure of clay soil, and enhances soil aeration.

　　2. Foliar fertilizer: Sprayed on crop leaves as a calcium fertilizer to  prevent and treat calcium deficiency in plants (such as tomato blossom-end rot  and apple bitter pit disease), while enhancing crop stress resistance.

　　3. Preservative: Soaking fruits and vegetables (such as apples and lettuce)  can delay senescence and extend the fresh-keeping period.

　　4. Food additive: Used as a coagulant in the production of tofu and jelly;  as a stabilizer and thickener in beverages and canned foods; as a calcium  supplement to fortify the calcium content of foods (such as biscuits and milk  powder).

　　5. Preservative in meat processing: Inhibits microbial growth while  maintaining the tenderness of meat.

　　Pharmaceutical and Environmental Protection Fields

　　1. Injection: Calcium chloride injection can be used to treat hypocalcemia,  magnesium poisoning, and allergic diseases (such as urticaria), and must be used  under the guidance of a doctor.

　　2. External medicine: Made into ointments or solutions for the treatment of  skin itching, eczema, etc.

　　3. Renal dialysis: Adjusts the calcium ion concentration of dialysate and  supplements calcium deficiency to maintain the patient's electrolyte balance,  prevent hypocalcemia-related complications, and assist in controlling  hyperphosphatemia.

　　4. Wastewater treatment: Used as a precipitant to remove fluoride ions,  phosphate, etc. from wastewater, forming insoluble calcium fluoride and calcium  phosphate precipitates; adjusts wastewater pH to promote the sedimentation of  heavy metal ions (such as lead and cadmium).

　　5. Dust suppressant: Spraying calcium chloride solution in coal mines and  mining sites to adsorb dust and reduce air pollution.
