Working Principle:
Ultrasonic is the sonic that the frequency is higher than 20KHz,when it spreads in the medium will cause the severe friction and heat dissipation between medium molecules.So that many primary and secondary ultrasonic effects happen,eg.: thermal,chemical,cavitation effect or others.
Due to the cavitation effect ,changes the reactivity of the reaction system.It produces the instant high temperature and high pressure during the chemical reaction,under this condition,chemical reaction speed is accelerated.
The secondary effect of ultrasonic,such as mechanical shock,emulsification,diffusion,smash are all good for mixing of reactants.Compared with traditional phase-transfer catalysis and mechanical stirring is more effective.
