Ultrasonic dispersing instrument uses ultrasonic cavitation to disperse agglomerated particles. The "cavitation" effect of ultrasonic wave in liquid forms local high temperature, high pressure or strong shock wave and micro jet, which propagates in the form of standing wave in the suspended body, causing the particles to be periodically stretched and compressed. The combination of these actions leads to the destruction of the agglomerate structure in the system, the enlargement of the particle gap and the formation of separate particles.
When ultrasonic waves act on the medium liquid, the distance between the molecules in the negative pressure zone will exceed the critical molecular distance that the liquid medium remains unchanged. The liquid medium will break, forming micro bubbles, and the micro bubbles will become cavitation.
The bubble can be redissolved in the gas, it can also float up and disappear, or it may collapse from the resonance phase of the ultrasonic field. It produces local high temperature and high pressure, and produce huge impact force and micro jet. Under the action of nano particle, the surface energy can be weakened, thus achieving the dispersion of nano particle.

1) Compared with the traditional mixing and ball milling process, the operation cost per unit capacity can be greatly reduced. It is especially suitable for industrial production.
2) For liquid-liquid mixture, the chemical reaction speed can be increased, the amount of additives can be reduced, and the fully mixed solution is not suitable for stratification for a long time.
3) For the solid-liquid mixture, the easily agglomerated nanoparticles can be opened in a short time, and the dispersed ultrafine particles are not easy to agglomerate again.
