Ultrasonic Apparatus Nanoparticles Dispersion System
Description:
The application of ultrasonic devices in nanoparticle dispersion is becoming increasingly widespread. With fast dispersion speed, ultrasonic devices can effectively disperse nanoparticles uniformly in liquid media in a short period of time without the need for large amounts of chemical additives, greatly reducing the impact on the environment.
The ultrasonic device nanoparticle dispersion system is an effective tool for achieving uniform dispersion of nanomaterials. By reasonable operation and parameter adjustment, the dispersion effect of nanoparticles can be significantly improved to meet the needs of different application fields.

Parameters Difference :
There are significant differences in the ultrasonic dispersion parameters of different types of nanoparticles, mainly reflected in the following aspects:
1. Particle size and shape
Larger particle size nanoparticles:
A lower frequency (such as 20 kHz -50 kHz) and higher power are required to generate sufficient energy to break the aggregation.
Example: Nano metal particles, nano oxides.
Smaller particle size nanoparticles:
Usually, higher frequencies (such as 100 kHz -1 MHz) are used to achieve more uniform dispersion.
Examples: Carbon nanotubes, nano silicon.
2. Material characteristics
Metal nanoparticles:
For metal nanoparticles, the ultrasonic treatment time is usually shorter to prevent oxidation.
The frequency is generally between 20 kHz and 100 kHz.
Polymer nanoparticles:
Lower power and longer processing time may be required to avoid thermal damage.
The frequency is usually between 20 kHz and 50 kHz.
Ceramic nanoparticles:
Usually requires higher power and longer time to ensure sufficient dispersion.
The frequency is generally between 20 kHz and 100 kHz.
3. Liquid medium
Water based medium:
For water-soluble nanoparticles, water is usually used as the dispersion medium, and the frequency and power can be moderate.
Organic solvents:
For hydrophobic or organically soluble nanoparticles, it may be necessary to choose a suitable organic solvent, and the selection of frequency and power should be adjusted according to the characteristics of the solvent.
4. Temperature sensitivity
Thermal sensitive material:
For some thermosensitive nanoparticles, lower power and shorter processing time are required to prevent thermal degradation.
5. Use of dispersants
Whether there is a dispersant:
When using dispersants, the processing parameters may need to be adjusted to improve the dispersion effect.
The type and concentration of dispersants can also affect the efficiency of ultrasonic treatment.
6. Application requirements
Specific applications:
Different applications, such as biomedical, coatings, and materials science, have different requirements for dispersion uniformity and particle size distribution. Therefore, it is necessary to adjust the parameters of ultrasonic dispersion to meet specific needs.
