calcium chloride 74% 77% flakes in 25kg and jumbo bags

Chemical Composition: Calcium chloride consists of one calcium ion (Ca^2+) and two chloride ions (Cl^-) in a 1:2 ratio, giving it the chemical formula CaCl2.

Physical Properties:

• Appearance: Calcium chloride typically appears as a white or colorless crystalline solid. It can also be found in various hydrated forms, such as dihydrate (CaCl2·2H2O) and hexahydrate (CaCl2·6H2O).
• Solubility: Calcium chloride is highly soluble in water, and its solubility increases with temperature. It is also soluble in alcohol and acetone.
• Hygroscopicity: Calcium chloride is hygroscopic, meaning it readily absorbs moisture from the air, forming a hydrated form of the compound.

Production: Calcium chloride is produced commercially by various methods, including the reaction of calcium carbonate (limestone) with hydrochloric acid (HCl), or as a byproduct of the Solvay process for manufacturing soda ash (sodium carbonate).

Applications:

• Deicing Agent: One of the most common uses of calcium chloride is as a deicing agent for roads, sidewalks, and parking lots during winter. It lowers the freezing point of water and melts ice, preventing the formation of ice and snow accumulation.
• Dust Control: Calcium chloride is applied to unpaved roads, construction sites, and mining operations to suppress dust by absorbing moisture from the air and soil, forming a stable surface.
• Concrete Accelerator: In construction, calcium chloride is used as a concrete accelerator to speed up the setting and curing process of concrete. It accelerates the hydration of cement, allowing for faster construction and reduced curing time.
• Food Additive: Calcium chloride is used as a food additive (E number E509) for various purposes, including as a firming agent, stabilizer, and preservative in processed foods such as canned fruits and vegetables, cheese, and tofu.
• Desiccant: Calcium chloride is employed as a desiccant to absorb moisture and humidity in storage areas, shipping containers, and electronic equipment. It helps to prevent moisture damage and corrosion.
• Water Treatment: In water treatment processes, calcium chloride is used for adjusting water hardness, controlling pH levels, and increasing the calcium content in water for various industrial and municipal applications.
• Drilling Fluids: Calcium chloride is added to drilling fluids in oil and gas exploration to control shale swelling and stabilize boreholes during drilling operations.

Safety Considerations:

• Calcium chloride is generally regarded as safe for its intended applications when used according to recommended guidelines. However, it can cause skin and eye irritation upon direct contact and should be handled with care.
• Ingestion of large quantities of calcium chloride may cause gastrointestinal irritation and electrolyte imbalance. It should be kept out of reach of children and pets.
• Proper ventilation and personal protective equipment should be used when handling calcium chloride in powdered or concentrated forms to minimize inhalation of dust and fumes.

Environmental Impact:

• Calcium chloride is considered to have minimal environmental impact when used as intended. However, its use as a deicing agent on roads and sidewalks can lead to environmental concerns such as corrosion of metal surfaces, damage to vegetation, and contamination of water bodies.
• Proper application practices and environmental stewardship are important for minimizing these potential impacts and ensuring responsible use of calcium chloride.
