Ultrasonic foil (papermaking)
Encyclopedia
High power ultrasonics
are used in the ultrasonic foils under the formation wire in a paper machine to produce paper of higher quality. On the top side of the formation wire over an ultrasonic foil, in the stock (fibre/water slurry), millions of pressure pulses from imploding cavitation
bubbles will keep the fibres apart, giving them a more uniform distribution. This will end up in better fibre formation, stronger paper and smoother paper surfaces.
Ultrasonics
Ultrasonics is a term meaning the application of ultrasound. It is often used in industry as a shorthand term for any equipment employing ultrasonic principles....

Cavitation
Cavitation is the formation and then immediate implosion of cavities in a liquidi.e. small liquid-free zones that are the consequence of forces acting upon the liquid...
