20Khz 1000W Ultrasonic Liquid Processor Dispersion Nano Processing Lab Equipment

Description:

Ultrasonic dispersion is a highly effective, versatile technology for achieving uniform and stable dispersions, critical for advanced material and product development.

How Ultrasonic Nano-Dispersion Works

1. Ultrasonic Wave Generation: High-frequency sound waves (usually 20–40 kHz) are introduced into the liquid via a transducer.

2. Cavitation Effect: The ultrasonic waves create microscopic bubbles in the liquid. These bubbles collapse violently, generating intense shear forces, localized high temperatures, and pressures.

3. Breaking Agglomerates:

• Nanoparticles, which tend to cluster due to van der Waals forces or static electricity, are separated by the cavitation-induced shear forces.

• This results in a stable, evenly distributed nanoparticle dispersion.

Advantages of Ultrasonic Dispersion

1. High Efficiency: Rapidly disperses particles, reducing processing time.

2. Uniform Distribution: Produces stable dispersions with consistent particle size.

3. Versatility: Works with a wide range of materials, from nanoparticles to pigments.

4. Scalability: Suitable for laboratory research and large-scale industrial production.

5. No Chemical Additives: Achieves dispersion without the need for stabilizers or surfactants in some cases.

Considerations

1. Sonication Power and Time: Excessive sonication can damage nanoparticles or alter their properties.

2. Medium Compatibility: Ensure the solvent and nanoparticles are compatible for stable dispersion.

3. Temperature Management: Avoid overheating sensitive materials by incorporating cooling systems.

4. Stabilizers: Use surfactants, polymers, or other stabilizing agents when necessary to prevent re-agglomeration.
