Dispersion for Emulsification

When ultrasonic waves act on liquids, a large number of small bubbles can be generated. One reason is that partial tensile stress occurs in the liquid to form a negative pressure. The decrease in pressure makes the gas originally dissolved in the liquid supersaturate and escape from the liquid and become small bubbles. Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.

Introduction：
Under the action of ultrasonic energy, two or more incompatible liquids are mixed together, and one of the liquids is evenly dispersed in the other liquid to form an emulsion liquid. This treatment process is called ultrasonic emulsification。
Advantage：
The type of emulsion can be controlled, the power required to produce the emulsion is small, and the formed emulsion is more stable.
