The principle of ultrasonic emulsification

Phacoemulsification refers to a process in which two (or more than two) insoluble Ultrasonic Handheld spot Welder liquids are mixed to form a dispersion system under the action of ultrasonic energy, and one type of liquid is evenly distributed in another liquid to form an emulsion.

Ultrasonic emulsification has the following features compared to general emulsification processes and equipment (such as propellers, colloid mills, homogenizers, etc.):

1. High emulsification quality

The resulting emulsion has a small average droplet size of 0.2 to 2 μm, a narrow range of droplet size distribution, 0.1 to 10 μm or less, high concentration, a pure emulsion concentration of up to 30%, and an emulsifier of up to 70%. .

2. Emulsion stability

Emulsifiers can be used without or with less to produce a stable emulsion, and some can be stable for months to more than six months, with low energy consumption, high production efficiency, and low cost.

3. Can control the type of emulsion

Under certain sound field conditions, both o/w (oil-in-water) and w/o (water-in-oil) emulsions can be prepared. However, this is not possible with mechanical emulsification. Only the nature of the emulsifier can control lactic acid. Types of. For example, toluene is emulsified in water and forms a type of milk under low sound intensity conditions.
