Basic Principles

The physical mechanism of crushing insoluble solids (or liquids) is the cavitation of ultrasound. Ultrasound cavitation effect means that under the action of strong ultrasound, a large number of bubbles will be generated in the liquid, and small bubbles will grow and increase gradually with the ultrasonic vibration, then suddenly burst and split, and the split bubbles will continue to grow and burst. The rapid collapse of these small bubbles produces high temperature and high pressure in the bubbles, and strong local shock waves are produced in the liquid near the bubbles because the liquid around the bubbles rushes into the bubbles at high speed, and local high temperature and high pressure are also formed, which results in the smashing and emulsification of ultrasound.

Phacoemulsification has the following outstanding characteristics

1. The average droplet size of emulsion formed by ultrasonic emulsification is small, which can be 0.2 ~ 2um. The droplet size distribution range is narrow, and it can be 0.1 ~ 10um or narrower.

2. The concentration of ultrasonic emulsion is high, the concentration of pure emulsion can exceed 30%, and the emulsifier can be up to 70%.

3, the emulsion formed is more stable. An important characteristic of phacoemulsification is that it can produce very stable emulsion without or without emulsifier.

4, the type of emulsion can be controlled. Under the condition of some acoustic fields, O/W (oil in water) and W/O (oil in water) emulsion can be prepared by ultrasonic emulsification. However, it is impossible to use mechanical emulsification. Only the nature of emulsifier can control the type of emulsion.

5. Toluene is emulsified in water. Under low acoustic intensity, a type of emulsion can be formed, while another type of emulsion is formed under high acoustic intensity.

6. The power required for the production of emulsified slag by ultrasonic emulsification is small.
