High Frequency Ultrasonic Treatment Technology For Suspension And Dispersion Of Pigment Solid Particles
Description:
The suspension and dispersion of pigment solid particles using ultrasonic high-frequency treatment technology is an effective method for improving the dispersion and uniformity of pigments in liquid media. This technology is widely used in industries such as coatings and inks, and has significant advantages.
The suspension and dispersion of pigment solid particles using ultrasonic high-frequency treatment technology effectively reduces the agglomeration of pigment particles, improves their dispersibility, and ensures the uniformity of coatings or inks. Uniform pigment dispersion helps improve the glossiness, coverage, and color consistency of coatings.

Factors :
The dispersion effect of pigments is not only affected by ultrasonic frequency and particle size, but also by the combined effect of multiple factors. Here are some main factors:
1. Liquid medium
nature:
The viscosity, density, and surface tension of solvents can affect the dispersion effect of pigments. Low viscosity solvents typically promote better dispersion.
Compatibility:
The compatibility between pigments and liquid media is also important, as different media may affect the dispersion stability of pigments.
2. Ultrasonic power
Power intensity:
Higher power can generate stronger cavitation effects and improve dispersion efficiency. However, excessive power may cause overheating or damage to certain temperature sensitive materials.
Processing time:
Appropriate ultrasonic treatment time is also crucial, as too short may result in uneven dispersion, while too long may lead to material degradation.
3. Particle shape and characteristics
Shape:
The shape of pigment particles (such as spherical, flake, or fibrous) can affect their fluidity and dispersibility.
Surface properties:
The surface energy, surface coating, and hydrophilic/hydrophobic properties of pigments can also affect the dispersion effect.
4. Additives
dispersant:
The use of appropriate dispersants can reduce the interaction force between pigment particles and promote better dispersion.
Stabilizers:
Stabilizers can prevent the precipitation of pigments after dispersion and improve the stability of suspensions.
5. Temperature
Temperature impact:
An increase in temperature usually reduces the viscosity of the liquid and promotes dispersion. However, excessively high temperatures may lead to the degradation of certain materials.
6. Mixing method
Pre treatment mixing:
Proper mechanical stirring before ultrasonic treatment can initially disperse pigments and enhance the effectiveness of ultrasonic treatment.
7. Ultrasonic mode
Continuous mode and pulse mode:
The application mode of ultrasound (continuous or pulse) will have different effects on the dispersion effect, and the pulse mode can reduce overheating and improve dispersion uniformity.
