Boric acid (H₃BO₃) is a weak, crystalline acid widely used in industrial, laboratory, and pharmaceutical applications. Due to its hygroscopic nature, it often contains adsorbed moisture or water of crystallization, which may affect its purity and performance in specific processes. Drying boric acid is a critical step to ensure its stability and suitability for precise applications.
Methods of Drying
Vibration Fluid Bed Dryer
The vibration source is driven by a vibration motor, which has balanced operation, easy maintenance, low noise and long service life.
High effection, raw material is heates evenly and heated evenly and heat exchange is fully used and dry capacity is high. Compared with ordinary drier, the energy can be saved about 30%.
Flash Dryer :
High-Efficiency Drying Mechanism: XSG Series Spin Flash Dryer employs a tangential air inlet and a high-speed stirrer to create a powerful rotating wind field. This ensures efficient heat transfer and uniform drying of paste, cake, and slurry materials.
Advanced Material Processing: The equipment processes raw materials through a combination of cutting, shearing, blowing, floating, and rotating actions, transforming them into granulated form. This enhances material separation and strengthens the heating exchange process.
Key Considerations
Temperature Control: Strict adherence to moderate temperatures prevents decomposition.
Hygroscopicity: Dried boric acid should be stored in airtight containers or desiccators to prevent reabsorption of moisture.
Safety: While boric acid has low toxicity, prolonged exposure to dust should be avoided. Use protective equipment during handling.
Applications of Dried Boric Acid
Anhydrous or properly dried boric acid is essential for:
Glass and ceramic production (as a flux).
Laboratory reagents (e.g., buffer solutions).
Flame retardants and preservatives.
Neutron absorption in nuclear industries.
In summary, effective drying ensures the chemical integrity and functionality of boric acid, making it a vital preparatory step across diverse fields. Proper technique and storage are paramount to maintain its quality.
