Application of Piezoelectric Ceramics in ultrasonic cleaning
What is ultrasonic cleaning?
Ultrasonic cleaning is a process of cleaning objects using high frequency sound waves in a liquid medium. The sound waves create high pressure bubbles that implode, generating tiny jets of cleaning solution that can remove contaminants from surfaces, crevices, and complex geometries. Ultrasonic cleaning is commonly used in industries such as electronics, medical devices, jewelry, and automotive, among others.
How Ultrasonic Cleaning Works?
The working principle of the ultrasonic cleaning machine is mainly to convert the sound energy of the power ultrasonic frequency source into mechanical vibration through the ultrasonic transducer, and radiate the ultrasonic wave to the cleaning liquid in the tank through the cleaning tank wall. Due to the radiation of ultrasonic waves, the micro-bubbles in the liquid in the tank can keep vibrating under the action of sound waves. Destroy the adsorption of the dirt and the surface of the cleaning part, causing the fatigue damage of the dirt layer to be separated, and the vibration of the gas bubble cleans the solid surface
Which piezo elements can be used for ultrasonic cleaning?
Ultrasonic cleaning devices consist of piezoelectric monolayer components of different shapes and sizes. Typically, for general purpose cleaning applications, a toroidal element of our PZT-40 material can be used to provide continuous power over an operating frequency range of 20-50kHz. Precision cleaning systems, such as those used in the semiconductor industry, tend to use smaller components, thin discs or plates, and operate at higher frequencies (40-200kHz).
