What are the main uses of Calcium Chloride Powder?

Calcium Chloride Powder is widely used in industry, agriculture and daily life due to its high specific surface area and rapid dissolution characteristics. In the industrial field, it is an efficient desiccant, often used to dry industrial gases such as nitrogen and oxygen, and can also be used as a dehydrating agent for alcohol and ester solvents; when used as a snow melting agent, the powder can quickly release heat when in contact with ice and snow, accelerate the melting speed, and has a low cost, which is suitable for large-scale deicing such as roads and parking lots. In agriculture, Calcium Chloride Powder can be configured into an aqueous solution and sprayed on fruits and vegetables to enhance the toughness of cell walls and extend the shelf life. It can also be applied to the soil as a calcium fertilizer to improve the symptoms of calcium deficiency in crops and improve the quality of fruits. In the construction industry, it is used as a concrete early strength agent to accelerate cement solidification and shorten the construction period. It is especially suitable for engineering construction in low temperature environments in winter; it can also be used to make moisture-proof agents to prevent wood, paper, etc. from getting damp and mildewing. In addition, powdered calcium chloride is used as a calcium enhancer and preservative in food processing, and is used in canned food, soy products, etc.; in oil production, it is used as a drilling fluid additive to stabilize the well wall and adjust the drilling fluid performance; in wastewater treatment, it removes pollutants such as phosphorus and fluorine through coagulation. Its powder form makes the reaction faster and the diffusion more uniform, which has irreplaceable advantages in scenarios that require rapid dissolution or high contact area.

What are the storage conditions for Calcium Chloride Powder?

The storage of Calcium Chloride Powder must strictly follow the principles of moisture-proof and pollution-proof to ensure its chemical activity and performance. Because it is very easy to deliquesce, it should be stored in a cool, dry and well-ventilated warehouse. The relative humidity of the warehouse should be controlled below 60%. Pads or plastic films should be laid on the ground to prevent moisture and avoid direct contact with the ground. The storage temperature should be kept at 0-30℃, away from heat sources, fire and acidic substances to prevent chemical reactions. The packaging requires the use of double-layer packaging with good sealing performance. The inner layer is a food-grade polyethylene film bag and the outer layer is a plastic woven bag. The seal must be tight to prevent air and moisture from entering. Unused Calcium Chloride Powder needs to be tied up in time, or transferred to a sealed container for storage. Products of different purity levels and uses (industrial grade, food grade) should be stored in separate areas and clearly marked. Mixed storage and placement are strictly prohibited to avoid cross contamination. Food-grade Calcium Chloride Powder must be strictly isolated from toxic and harmful substances to ensure compliance with food safety regulations. During transportation, use closed vehicles with moisture-proof measures to prevent rain and exposure to the sun. Handle with care during loading and unloading to avoid damage to the packaging. Ensure that the Calcium Chloride Powder remains dry and pure during storage and transportation to maintain its stable quality.

Does Calcium Chloride Powder react with Other Chemicals?

As a strong electrolyte, Calcium Chloride Powder has active chemical properties and is easy to react with a variety of chemical substances. The specific reaction types and conditions are as follows: Reaction with alkaline substances: When encountering strong bases such as sodium hydroxide and potassium hydroxide, calcium hydroxide precipitate (CaCl₂ + 2NaOH = Ca(OH)₂↓ + 2NaCl) will be generated. Especially in aqueous solution, the reaction is rapid, and the generated calcium hydroxide is slightly soluble in water, which may cause the solution to be turbid. Reaction with carbonates and sulfates: When reacting with carbonates such as sodium carbonate and potassium carbonate, a white precipitate of calcium carbonate (CaCl₂ + Na₂CO₃ = CaCO₃↓ + 2NaCl) is generated. This reaction is often used for industrial decalcification or preparation of calcium carbonate; when reacting with sodium sulfate and potassium sulfate, a calcium sulfate precipitate (CaCl₂ + Na₂SO₄ = CaSO₄↓ + 2NaCl) is generated. White flocculent precipitate can be observed in the solution. Reaction with silver salts: It reacts with silver nitrate solution to form silver chloride precipitate (CaCl₂ + 2AgNO₃ = 2AgCl↓ + Ca(NO₃)₂), producing a white precipitate that is insoluble in dilute nitric acid and is often used for qualitative testing of chloride ions. Reaction with certain metal elements: In the molten state, calcium is highly active and can undergo replacement reactions with metals such as potassium and sodium (such as CaCl₂ + 2Na = 2NaCl + Ca), but the solid-state reaction is extremely slow at room temperature and requires high temperature conditions to promote it. Special reaction with acidic substances: Although it is a salt, it may form calcium phosphate precipitate when it encounters concentrated phosphoric acid (3CaCl₂ + 2H₃PO₄ = Ca₃(PO₄)₂↓ + 6HCl), and the reaction with dilute acid must be carried out under specific conditions, and the acidic environment will inhibit its hydrolysis. In addition, powdered calcium chloride releases heat when it comes into contact with water. If it comes into contact with flammable substances (such as metallic sodium) and there is moisture, it may cause danger due to heat accumulation, so mixed storage should be avoided.

What is the production process of Powdery Calcium Chloride?

The production process of powdered calcium chloride is a delicate technique. At the beginning of the process, high-quality calcium sources are selected, mostly limestone. The limestone is calcined to turn it into calcium oxide. This calcination process requires control of the heat and timing. If the heat is too fierce, the quality will be inferior, and if it is too slow, it will take time and reactive work. When calcium oxide is obtained, it is combined with hydrochloric acid. At the time of this synthesis, the reaction state must be carefully observed, and the rate and temperature must be controlled. If the rate is too rapid, the reaction may be uneven; if the temperature is not appropriate, it will also affect the quality of the product. After the combination of the two, a solution of calcium chloride is obtained. However, this solution still needs to be refined. If impurities exist, the purity of calcium chloride will be damaged. Therefore, the method of precipitation and filtration is used to remove the insoluble matter; and the method of ion exchange is used to remove the heteroions. After this refinement, a pure calcium chloride solution is obtained. Then, the step of evaporation and concentration is carried out. Make the solution at a suitable temperature and pressure, the water gradually evaporates, and the concentration of calcium chloride gradually rises. At the appropriate time, transfer to the crystallizer. The method of crystallization is either cooling or evaporation, according to the situation. Cooling and crystallization requires controlling the speed of cooling; evaporation and crystallization requires looking for the loss of solvent. After crystallization is completed, a crystal of calcium chloride is obtained. After drying, remove its moisture content. When dry, the temperature should not be high, high or cause crystal decomposition; nor low, low moisture is difficult to remove. Finally, powdery calcium chloride is obtained, with uniform particles, pure quality and stable performance, which can be used for various industrial and civilian needs.

What is the proportion of Powdery Calcium Chloride used in different industries?

The proportion of powdered calcium chloride used in various industries is difficult to generalize. Due to the different industries, the demand is very different. This test takes several industries as an example to briefly demonstrate the situation. In the chemical industry, powdered calcium chloride is widely used. It is often used as a desiccant. Because of its strong hygroscopicity, it can keep the environment dry, and the proportion of uses is about 30%. It is also used in the manufacture of other calcium salts. It is an important raw material for chemical synthesis, accounting for about 20%. In the construction industry, powdered calcium chloride can be used as an antifreeze. During construction in cold weather, it can help concrete solidify quickly and improve construction efficiency. This use accounts for about two-thirds of the overall consumption. In the food industry, powdered calcium chloride can be used as a preservative and chelating agent, which can prolong the shelf life of food and stabilize the structure of food. Its use ratio is about 15%. In the field of road maintenance, powdered calcium chloride can be used as a snow-melting agent. When snowfall falls in cold winter, it is scattered on roads to make ice and snow melt quickly and ensure traffic safety, accounting for about 10%. As for other industries, such as agriculture, pharmacy, etc., powdered calcium chloride also has its own uses, but the dosage is relatively small, accounting for about 5%. It can be seen that the proportion of powdered calcium chloride used in different industries varies significantly, depending on the characteristics of the industry and actual needs.
