60kHz High-Temperature Vortex Ultrasonic Spray Coating System

60kHz High-Temperature Vortex Ultrasonic Spray Coating System

Description: 

Our 60kHz high-temperature vortex ultrasonic spray coating system integrates a 60 kHz vortex ultrasonic atomizing nozzle with built-in cooling structure. Piezoelectric transducer generates high-frequency vibration to turn liquid precursors into fine micro-droplets. Low-speed vortex shaping gas forms a stable conical spray field without strong impact on substrates.

The nozzle cooling assembly isolates heat from the high-temperature heating stage, which can reach up to 500~600°C. This design enables in-situ drying and thermal decomposition of precursor solutions directly on the substrate surface.

Compared with conventional focused ultrasonic spray nozzles, the vortex type offers wider effective spray width and superior coating uniformity. Soft mist greatly reduces overspray and improves material utilization above 90%, saving expensive precious metal precursor materials. Ultrasonic self-cleaning performance minimizes nozzle clogging for suspensions, sols and salt solutions.

Equipped with precision liquid feeding module, independent gas control unit and XYZ servo motion platform, the system supports programmable coating paths. It can deposit thin films ranging from tens of nanometers to micrometers.

Typical applications include fuel cell catalyst layers & PEM coating, perovskite solar cells, TCO and metal oxide films, MEMS & wafer functional coatings, sensor nano-film fabrication.
