Experimental ultrasonic dispersion
It can also be called ultrasonic disperser, small dispersing equipment, portable ultrasonic dispersing machine. The standard configuration is composed of three parts: ultrasonic generator (ultrasonic power supply), host and bracket, and optional installation of soundproof box, alarm output, remote control and anti-corrosion TIP. The device is small in size and light in weight. It can be held in your hand for micro-samples or placed on a fixed support. Mainly used for laboratory research. The ultrasonic power is 500W to 1000W; the frequency is 20K, 28K, 40K; the processing capacity is 0.2 to 5L.
Ultrasound has been used more and more widely in processes such as chemistry, chemical engineering and biology. This is mainly based on the cavitation of ultrasound. Ultrasonic cavitation refers to the dynamic process of growth and collapse of micro-gas core cavitation bubbles in the liquid that vibrate under the action of sound waves, and when the sound pressure reaches a certain value. When ultrasonic waves act on liquids, a large number of small bubbles can be produced. One reason is that partial tensile stress appears 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.
The cavitation threshold is the lowest sound intensity or sound pressure amplitude that causes the liquid medium to produce cavitation. Only when the alternating sound pressure amplitude is greater than the static pressure can negative pressure appear. And only when the negative pressure exceeds the viscosity of the liquid medium, cavitation occurs. The cavitation threshold varies with different liquid media. For the same liquid medium, the cavitation threshold is also different for different temperatures, pressures, cavitation nuclei radius and gas content. Generally speaking, the lower the gas content of the liquid medium, the higher the cavitation threshold. The cavitation threshold is also related to the viscosity of the liquid medium. The greater the viscosity of the liquid medium, the higher the cavitation threshold. The cavitation threshold has a very close relationship with the frequency of ultrasound. The higher the frequency of ultrasound, the higher the cavitation threshold. The higher the frequency of ultrasound, the more difficult it is to cavitation. To produce cavitation, the intensity of ultrasound must be increased.
Ultrasound is widely used in various fields, which is the application of its cavitation and its cavitation is accompanied by mechanical, thermal, chemical, biological, and so on. The application of mechanical and chemical effects, the former is mainly manifested in the increase of the heterogeneous reaction interface; the latter is mainly due to the high temperature and high pressure generated in the cavitation process which causes the decomposition of polymers, the breakage of chemical bonds and the generation of free radicals. The processes that use mechanical effects include adsorption, crystallization, electrochemistry, heterogeneous chemical reactions, filtration, and ultrasonic cleaning. The processes that use chemical effects mainly include organic degradation, polymer chemical reactions, and other free radical reactions.
