Calcium Chloride Dihydrate Powder

Calcium Chloride Dihydrate Powder
Synonyms: Calcium Dichloride Dihydrate, CaCl₂·2H₂O
CAS Number: 10035-04-8
Molecular Formula: CaCl₂·2H₂O

Description:

Calcium Chloride Dihydrate (CaCl₂·2H₂O) is a white crystalline powder that is highly soluble in water. It is a hydrated form of calcium chloride, with two water molecules bound to each calcium chloride unit. The compound is hygroscopic, meaning it readily absorbs moisture from the air. This makes it ideal for use in moisture control, as well as in various industrial and commercial applications. It is commonly used in de-icing, food processing, water treatment, and as a firming agent in a variety of other applications.

Applications:

1. De-Icing and Dust Control:
   • De-Icing: Calcium Chloride Dihydrate is widely used as a de-icing agent for roads, sidewalks, and pavements due to its ability to lower the freezing point of water and rapidly melt ice.
   • Dust Control: Applied to unpaved roads, construction sites, and mines to control dust by retaining moisture in the soil.
2. Food Processing:
   • Food Additive (E509): Used as a firming agent in canned vegetables and fruits, and as a calcium fortifier in various food products.
   • Brewing and Cheese Making: Added to beer brewing to adjust water hardness, and in cheese making to improve curd formation.
3. Water Treatment:
   • Functions as a water hardening agent in aquariums and swimming pools.
   • Used in industrial water treatment processes to remove impurities and neutralize acidity.
4. Desiccant:
   • Acts as a drying agent in laboratory and industrial applications due to its hygroscopic properties.
   • Commonly used in packaging materials and moisture-absorbing pouches to prevent moisture damage.
5. Concrete Accelerator:
   • Speeds up the setting time of concrete in construction, particularly in cold weather conditions.
   • Improves the durability and early strength of concrete structures.
6. Pharmaceuticals and Medical Use:
   • In pharmaceutical applications, calcium chloride solutions are used to correct calcium deficiencies and as an electrolyte replenisher in medical treatments.

Advantages:

• Highly Soluble: Easily dissolves in water, making it effective for applications like de-icing and dust control.
• Moisture Absorption: Excellent hygroscopic properties, making it ideal for moisture control and as a desiccant.
• Multi-Industry Use: Versatile compound with applications across several industries including food, water treatment, and construction.
• Non-Toxic: Safe for use in food processing and medical applications when used in the appropriate quantities.

Handling and Storage:

• Storage Conditions: Store in a tightly sealed container in a dry, cool area away from moisture and heat. Keep packaging closed when not in use to prevent absorption of moisture from the air.
• Shelf Life: Stable when stored properly, but its hygroscopic nature may cause clumping if exposed to moisture.
• Handling Precautions: Avoid inhaling dust or allowing contact with skin and eyes. Use appropriate personal protective equipment (gloves, goggles, mask) when handling in bulk. In case of contact, rinse thoroughly with water.
