Ultrasonic dispersers are also known by many customers as ultrasonic mixers, ultrasonic emulsifiers, ultrasonic mixing equipment and so on. This is because the cavitation effect of ultrasonic waves in liquids is the name of different customer needs.
Ultrasonic sonochemistry is an emerging interdisciplinary subject that uses ultrasonic to accelerate chemical reactions and improve chemical yields.
Ultrasonic action can promote the occurrence of chemical reactions that cannot occur under normal conditions or increase the existing reaction rate and degree of reaction.
These are not the result of sound waves acting directly on the reactants, because only low-frequency power ultrasound is used in liquids, with wavelengths between 10cm and 0.015cm (corresponding to frequencies between 10 kHz and 10 mHz), much larger than molecules. Between the dimensions, it is generally believed that the above phenomena occur mainly due to ultrasonic mechanical action and cavitation, which are the result of changing the conditions and environment of the reaction.
A branch of chemistry that studies the changes in chemical reactions or chemical reaction processes caused by ultrasonic waves. Also known as ultrasonic chemistry. The ultrasonic frequency used for chemical reactions is usually 20 to 50 kHz, the device that generates ultrasound is called an ultrasonic generator, and the core component is a piezoelectric crystal or a magnetostrictive element.
Ultrasonic disperser function
1. Ultrasonic vibration source (drive power supply): converts 50-60 Hz mains into a high-power high-frequency (15 kHz-100 kHz) power supply, which is supplied to the transducer.
2. transducer (transducer): converts high-frequency electrical energy into mechanical vibrational energy.
3. A horn: The transducer and the tool head are coupled and fixed, and the amplitude of the transducer is amplified and transmitted to the tool head.
4. Tool head (introduction rod): It transfers mechanical energy and pressure to the work, and also has the function of amplitude amplification.
