Compact Ultrasonic Coating Machine
Working Principle
Ultrasonic nozzles use an internal transducer to convert high-frequency sound waves into mechanical energy, which is then transferred to the liquid to generate standing waves. Liquid is introduced through a nozzle onto the atomizing surface. Upon exiting the nozzle's atomizing surface, the liquid is broken into a uniform mist of micron-sized droplets, achieving atomization. Under the action of a carrier gas (generally at a pressure of ≤0.15 MPa), the atomized droplets are formed into shapes such as thin lines, cones, and wide flats, which are evenly applied to the substrate surface to form a coating or thin film.
Equipment Features
-
High Coating Quality: A more uniform spraying effect is achieved, with coating uniformity within ±5%. Film thickness can be as thin as tens of nanometers, and precise control of coating thickness is possible, enabling coatings ranging from tens of nanometers to tens of microns to be produced.
-
High Material Utilization: Ultrasonic nozzles do not require air pressure to generate atomization, significantly reducing paint splashing during the spraying process. Paint utilization rates exceed 85%, over four times that of traditional two-fluid spraying.
-
Ultrasonic nozzles are less prone to clogging: Ultrasonic nozzles maintain ultrasonic cavitation throughout their operation, making them less prone to clogging and reducing maintenance costs.
-
Easy to operate: They are typically equipped with a full-color touchscreen and a user-friendly interface for easy operation. Some units also feature laser-assisted positioning, allowing users to quickly set the spray starting position.
-
Strong scalability: They can be configured with various features, such as an ultrasonic dispersion and liquid supply system, a micron-level vacuum heating device, and a high-temperature hot plate, to meet diverse spraying needs.
