Ultrasonic Spray Coating Machine with 20-200Khz Frequency, 1-15W Max Power, and 15-45μm Particle Size for Precision Atomization

Ultrasonic micron level atomizing spray machine transforms liquid (solvent or water-based and nano/particle containing suspension) into uniform micron level droplets for precision spraying. It is widely used in photoelectric display films, electronic component coating, medical spray, functional coatings, sensors, nano material deposition and other fields.

• Ultrasonic transducers (piezoelectric ceramics) generate mechanical vibrations under high-frequency (usually tens to hundreds of kilohertz) electrical oscillation driving
• Vibration transfers to the working surface to form a stable liquid film and generate capillary waves, producing droplets at the wave peaks
• Droplet size is affected by frequency, liquid surface tension, viscosity, and supply method
• Unlike pneumatic spraying, ultrasonic atomization does not require high-pressure gas source, resulting in milder droplets and narrower particle size distribution

• Optical thin film: ITO solution, functional nanoparticle thin film, anti reflective layer
• Electronic packaging and printed circuit boards: wetting agents, protective coatings, thin adhesive layers
• Medicine/Biology: Drug nebulization administration, solution chromatography pretreatment, protein/enzyme activity coating
• Functional coatings: hydrophobic/hydrophilic coatings, sensor sensitive layers, catalyst loading layers
• Nano material deposition: uniform deposition of dispersed carbon nanotubes and oxide nanoparticles
