What Is Ultrasonic Dispersion Technology

The most prominent and widely known effect of power ultrasound in liquids is the dispersion effect. The dispersion of ultrasound in liquids relies primarily on the ultrasonic cavitation of the liquid.

There are two factors that determine the effect of dispersion: ultrasonic impact; ultrasonic radiation time.

When the flow of the treatment liquid is Q, the gap is c, and the area of the plate in the opposite direction is S, the average time t required for the specific particles in the treatment liquid to pass through this space is: t=c*S/Q. To improve the ultrasonic dispersion effect, it is necessary to control the three factors of the average pressure p of the treatment liquid, the gap c, and the ultrasonic irradiation time t(s).

Ultrasonic dispersion can be used without emulsifier. In many cases, emulsification can obtain particles of 1 μm or less. The formation of this high-quality emulsion is mainly due to the formation of ultrasonic cavitation near the dispersion tool. The chemical agent can disperse the paraffin in water, and the dispersed school has a diameter of less than 1 μm.

Ultrasonic dispersion holding points are usually small in vibration and large in acceleration. Ultrasonic dispersing devices have been widely used in food, fuel, new materials, chemical products, paints and other fields.
