Phacoemulsification refers to the process of mixing two (or more than two) immiscible liquids uniformly to form a dispersion system under the action of ultrasonic energy, and one of the liquids is evenly distributed in the other liquid to form an emulsion.
The physical mechanism of crushing insoluble solids (or liquids) is considered to be ultrasonic cavitation. Ultrasonic cavitation effect means that a large number of bubbles will be generated in the liquid under the action of strong ultrasonic waves. Small bubbles will gradually grow and increase with the ultrasonic vibration, and then suddenly burst and split, and the split bubbles will continue to grow and burst. . When these small bubbles collapse rapidly, high temperature and high pressure are generated in the bubble, and because the liquid around the bubble rushes into the bubble at high speed, a strong local shock wave is generated in the liquid near the bubble, and a local high temperature and high pressure is also formed. Ultrasonic pulverization and emulsification.
In the pharmaceutical industry and the daily necessities industry, phacoemulsification is often used in the manufacture of various emulsion products, such as emulsion drugs, cosmetics, and shoe polish. Ultrasonic emulsification method can also be used to make emulsified combustion products of oil (gasoline, diesel, etc.) and water or pulverized coal to increase the combustion value per unit of fuel.
This technology has now been promoted and used in a limited range, and the economic benefits are obvious. In order to reduce costs and adapt to larger-scale production, mechanical ultrasonic transducers such as reed whistles are mostly used in phacoemulsification. For liquids that are difficult to emulsify or due to other special considerations, piezoelectric ultrasonic transducers are sometimes used, and an appropriate sound focusing system is used to increase the sound intensity.
The average droplet size of the emulsion formed by ultrasonic emulsification is small, which can be 0.2 ~ 2um; the droplet size distribution range is narrow, which can be 01 ~ 10um or narrower.
The concentration of ultrasonic emulsion is high, the concentration of pure emulsion can exceed 30%, and the addition of emulsifier can be as high as 70%.
The formed emulsion is more stable. An important feature of phacoemulsification is that it can produce a very stable emulsion without or using less emulsifiers.
The type of emulsion can be controlled. Using phacoemulsification, under certain sound field conditions, both O/W (oil-in-water) and W/O (water-in-oil) emulsions can be prepared; however, it is impossible to use mechanical emulsification methods, only the properties of emulsifiers In order to control the type of emulsion.
Toluene is emulsified in water, one type of emulsion can be formed under low sound intensity conditions, and another type of emulsion can be formed under high sound intensity conditions.
Ultrasonic emulsification requires low power to produce milk residue.
