Ultrasonic Suspension Fine Dispersion Technology For 20Khz Coating

The 20Khz coating ultrasonic suspension fine dispersion technology is a method that uses low-frequency ultrasound to achieve efficient dispersion and uniform suspension of pigments and additives in coatings.

The 20Khz coating ultrasonic suspension fine dispersion technology can achieve high dispersion effect in a short time through ultrasonic vibration, reduce production cycle, and improve the color consistency, glossiness, and coverage of the coating through uniform pigment dispersion, thereby enhancing the stability of the coating.

• Cavitation effect
  Low frequency ultrasound (usually in the range of 20 kHz to 100 kHz):
  It can generate larger bubbles, which release stronger energy when they collapse, helping to break the aggregation of larger particles.
  More suitable for handling the dispersion of larger particles and high viscosity liquids.
  High frequency ultrasound (usually above 100 kHz):
  The generated bubbles are small, and the local energy generated during collapse is high, but the dispersion effect on larger particles is limited.
  More suitable for handling small particles and applications that require high uniformity.
• Dispersion speed
  Low frequency: Usually has a fast dispersion speed, but may cause larger particles to still exhibit significant aggregation after dispersion.
  High frequency: The dispersion speed is relatively slow, but it can achieve a more uniform dispersion effect and reduce particle aggregation.
• Impact on liquids
  Low frequency ultrasound: may cause overheating of liquids and excessive vigorous movement of bubbles, leading to changes in the physical properties of liquids.
  High frequency ultrasound: has less thermal impact on liquids and is more suitable for temperature sensitive materials.
• Applicable materials
  Low frequency: Suitable for materials with high viscosity and large particles, such as certain inks and coatings.
  High frequency: suitable for nanometer materials, lotion and other dispersion systems requiring high stability.
