MSK-SPHVS Ultrasonic Spray Nozzle 20 kHz 3.5 kW for High Viscosity Slurry Spray Pyrolysis Coating and Granulation
The MSK-SPHVS ultrasonic spray nozzle is engineered to atomize high viscosity liquid solutions for applications such as spray pyrolysis coating and spray granulation. This system is particularly suited for processing viscous slurries by converting them into fine droplets, facilitating uniform thin film deposition or particle formation. Its capability to handle liquids with viscosities up to 2,000 mPa·s makes it ideal for challenging coating tasks where conventional atomization methods may fail.
Operating at a low ultrasonic frequency of 20 kHz combined with a high adjustable power output of up to 3.5 kW, the device efficiently generates ultrasonic energy to break the liquid into droplets averaging 10 to 20 micrometers in diameter. The nozzle uses a piezoelectric zirconate titanate (PZT) converter with a 25 mm diameter to produce ultrasonic vibrations. The atomization process is assisted by low-pressure compressed air, which can be regulated between 1 and 500 sccm, enabling precise control over spray characteristics.

대표적인 적용 분야
This ultrasonic spray nozzle is ideal for spray pyrolysis coating of high viscosity slurries, enabling uniform thin film formation on substrates. It is also suitable for spray granulation processes where controlled droplet size and distribution are critical. The device supports research and development in materials science, thin film deposition, and particle engineering involving viscous liquid formulations.
구성 및 작동 안내
The system includes the ultrasonic generator and spray nozzle assembly. To achieve uniform liquid delivery, an infusion syringe pump is recommended but sold separately. For spray pyrolysis coating, a heating plate may be required to facilitate solvent evaporation and film formation. Additionally, an X-Y axis CNC stage can be integrated for automated coating patterns. Operating the device inside a fume hood is advised for safety due to aerosol generation. These accessories are optional and available at extra cost.
