Calcium Chloride Anhydrous

Calcium Chloride Anhydrous is a white crystalline solid with a purity of 94-96%. It is a highly hygroscopic compound, meaning it absorbs moisture from the air, making it ideal for use in applications where moisture control is critical. The anhydrous form of calcium chloride is widely used in industrial processes, water treatment, de-icing, and desiccation due to its high moisture absorption capacity. It is also used in various chemical and food industries.

Applications:

1. Moisture Absorbent / Desiccant:
   • Desiccant: Used in moisture control applications in laboratories, packaging, and storage. It helps in drying gases, organic solvents, and air in compressed air systems.
   • Dehumidification: Employed in industrial and commercial settings to reduce humidity in air and enclosed spaces.
2. De-Icing and Dust Control:
   • De-Icing Agent: Applied on roads, highways, and walkways to prevent ice formation and melt existing ice in cold climates. It is more effective than sodium chloride at lower temperatures.
   • Dust Control: Used to suppress dust on unpaved roads, construction sites, and in mining operations by retaining moisture in the soil.
3. Water Treatment:
   • Hardness Adjustment: Added to water to increase calcium levels in swimming pools, aquariums, and industrial water treatment processes.
   • Wastewater Treatment: Used to precipitate fluoride, phosphate, and other contaminants from wastewater.
4. Food Processing:
   • Food Additive (E509): Approved for use in the food industry as a firming agent, preservative, and to add calcium in pickling and brewing. It is used in the preparation of cheeses and tofu, and as a dough conditioner.
5. Construction:
   • Concrete Accelerator: Calcium Chloride Anhydrous is used as an accelerating agent in the setting of concrete, especially in cold weather to speed up curing time.
   • Anti-Freeze: Prevents freezing in building materials and reduces the effects of low temperatures during construction projects.
6. Chemical Industry:
   • Drying Agent: Commonly used in chemical reactions as a drying agent for liquids and gases.
   • Manufacturing: Involved in the production of a wide range of products, including plastics, rubber, and glass.

Advantages:

• Effective at Lower Temperatures: Provides superior de-icing capability compared to sodium chloride, especially in sub-zero temperatures.
• Hygroscopic Nature: Excellent for moisture control in various applications due to its ability to absorb large amounts of water.
• Multi-Industry Applications: Versatile and widely used across multiple industries such as agriculture, construction, and food processing.
• Highly Soluble: Easily dissolves in water, enabling efficient use in industrial processes and water treatment.

Handling and Storage:

• Storage Conditions: Store in a tightly sealed container in a dry, cool area to avoid moisture absorption. Keep away from incompatible substances like water and acids.
• Shelf Life: Stable under recommended storage conditions; avoid exposure to air or moisture to maintain quality.
• Handling Precautions: Use appropriate personal protective equipment (PPE) such as gloves, goggles, and masks. Avoid inhalation, ingestion, and contact with skin or eyes. In case of contact, rinse thoroughly with water.
