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.
Description
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.
