1, ultrasonic disperser principle
Ultrasonic dispersion is widely used in laser particle size measurement. It disperses and transmits the ultrasonic signal to the ultrasonic transducer. After the transducer transforms into high-frequency mechanical vibration energy and transmits it to the medium, the medium molecules vibrate to form High pressure shock waves act on the particles, dispersing the agglomerated particles. Ultrasonic dispersers have excellent dispersibility for most samples and have become indispensable to laser particle size measurement systems.
2, built-in ultrasonic disperser
Built-in ultrasonic disperser is the ultrasonic generator (power) and the transducer installed in the circulatory system to form a loop with, dispersion, mixing function in one of the sample preparation system. The system works continuously before and during the test to ensure that the sample is well dispersed and prevents the particles from reuniting, ensuring that the ultrasonic dispersion of the sample remains stable throughout the test.
3, conventional ultrasonic disperser to add water
Ultrasonic disperser work, the high-power high-frequency electrical signal is added to the ultrasonic transducer, the transducer through the electrical signals into high-frequency mechanical vibration wave to achieve decentralized function.
Due to the continuous effect of high-power high-frequency signals, the transducer temperature will continue to rise, the conventional ultrasonic disperser is to ensure that the water circulating in the pool to suppress the temperature rise of the transducer, but often because of new, misuse And other reasons, forget to add water before starting the ultrasound, resulting in a sharp rise in the temperature of the ultrasonic transducer and burned.
