Ultrasonic spraying technology combines ultrasonic atomization nozzles with low-pressure air (gas) to produce gentle, highly focused喷雾液滴束。Compressed air (gas) is typically introduced at 1psi into the diffuser chamber surrounding the nozzle, creating a uniformly distributed air/gas flow around the nozzle stem. The spray produced by the ultrasonic tip at the nozzle's end is immediately entrained in the low-pressure air stream.

The adjustable focusing mechanism on the gas hood allows complete control over the spray width. The spray envelope is extremely narrow, resembling an hourglass. The width of the shape is controlled by adjusting the distance between the nozzle and the substrate, ranging from 1.78 to 25 millimeters. Ultrasonic spraying technology can apply pure solutions to high-solids suspensions and pastes on the surface of objects, resulting in more even, thinner, and controllable film coatings. The dry film thickness can reach several nanometers, making it a nanometer-level spraying method.
