How ultrasonic spraying works?

The benefits of ultrasonic spraying
1.Some benefits of ultrasonic nozzles;
2.High transmission efficiency – reduce material usage;
3.Non-clogging – capable of handling high solids materials;
4.Durability – Titanium construction resists many solvents and wear;
5.Highly uniform distribution of droplet size – reduces coating defects;
6.Airless spraying – can easily control the process, also ideal for vacuum environment!

How Ultrasonic Spraying Works
Ultrasonic nozzles contain piezoelectric transducers that vibrate at high frequencies when energized. The design of these transducers causes the nozzle to vibrate longitudinally, so the tip of the nozzle vibrates in an up-and-down motion several thousand times per second. When a thin film of liquid is applied to the tip of an ultrasonic nozzle, capillary waves are formed. The amplitude of these waves can easily be controlled by a sonotrode, and the amplitude is increased to the point that these upright capillary waves become too high to support themselves. The material is discarded due to the continuous overextension of these standing waves, starting to form micron-sized, highly uniform droplets. Under the right conditions, nebulization can last for a long time.

These stationary liquid waves can extend upward from the tip of the ultrasonic nozzle until they separate into uniformly sized droplets with little kinetic energy. If desired, the droplets can be easily formed into the desired shape and velocity using a secondary forming gas or ambient air. A variety of ultrasonic nozzles are made to help determine droplet size, liquid flow rate and spray pattern. Ultrasonic spray still retains many of the same basic principles since its commercial introduction in the 1970s. Expansion of various frequencies to introduce ultrasonic spray systems into harsh environments such as spray pyrolysis, CVD and vacuum.
