How does the ultrasonic sprayer work?
May 22,2024
An ultrasonic spraying machine works by utilizing the principle of ultrasonic vibration to coat surfaces. Its operation involves several steps:
1. Coating Supply: The coating material is conveyed to the nozzle of the spraying machine. This is typically achieved through a coating supply system such as a pressure tank or pump.
2. Ultrasonic Vibration: The ultrasonic spraying machine generates high-frequency vibrations through an ultrasonic transducer. These vibrations are transmitted to the coating material, causing it to form tiny droplets.
3. Spray Formation: Under the influence of ultrasonic waves, the coating material forms a fine spray due to surface tension and the fluidity of the liquid.
4. Spraying: The generated spray is delivered to the nozzle and then sprayed onto the surface to be coated using a gas flow, typically air.
5. Coating Curing: After forming a layer on the surface, the coating material is cured and adheres to the surface through various methods such as natural drying, heating, or UV curing.
The advantages of ultrasonic spraying machines include uniform spray, dense coatings, and savings in coating material. They are suitable for coating various materials and surfaces.
