Ultrasonic Atomization and Cavitation
Excessive energy will cause liquid emerging from the nozzle to prematurely aerosolize, which is not ultrasonic atomization. Cavitation occurs. Read More…
What is the Difference between an ultrasonic nebulizer and ultrasonic nozzle?
Ultrasonic nebulizer utilizes the surface of the piezoelectric disk as the surface for atomization, whereas an ultrasonic nozzle uses the piezos as a driver. Read More…
Is smaller droplet size always better?
Type of solvent, distance the nozzle is from the substrate and flow rate all play a role in determining the final droplet size and thus quality of coating. Read More…
How to prevent agglomeration of spray coatings
Ultrasonic nozzles can inhibit agglomeration “clumping” of nanoparticles, nanowires, platinum carbon black inks used in hydrogen fuel cells, flux, etc. Read More…
How nozzle design impacts flow rate
So if flow rate is not a function of air, what drives liquid velocity in the case of an ultrasonic nozzle? The answer is the pumping mechanism and the orifice. Read More…
