Flow Chart of Piezo Ring

The process flow chart is as follows: batching – mixed grinding – pre sintering – secondary grinding – granulation – molding – plastic discharge – sintering into porcelain – shape processing – electrode – high voltage polarization – aging test.The manufacturing feature of piezoelectric ceramics is to polarize ferroelectric ceramics under DC electric field to make them have piezoelectric effect. Generally, the polarization electric field is 3 ~ 5kV / mm, the temperature is 100 ~ 150 ° C, and the time is 5 ~ 20min. These three factors are the main factors affecting the polarization effect. The electromechanical coupling coefficient of piezoelectric ceramics with good performance, such as lead zirconate titanate ceramics, can be as high as 0.313 ~ 0.694.

Good sound quality
The Replacement of the Piezo Ceramic Ring

Generally, the piezo ceramic sheet needs to be replaced after a period of use. When a good ceramic sheet is used not hot.

Principle of ultrasonic cleaning

The mechanism of ultrasonic cleaning is to use the physical effects such as cavitation, radiation pressure and sound flow when ultrasonic wave propagates in the cleaning fluid to peel off the dirt on the cleaning parts mechanically, and promote the chemical reaction between the cleaning fluid and dirt to achieve the purpose of cleaning objects. The frequency used by the ultrasonic cleaning machine can be 10 ~ 500 kHz according to the size and purpose of the cleaning object, generally 20 ~ 50 kHz. With the increase of ultrasonic transducer frequency, langzhiwan vibrator, longitudinal vibrator, thickness vibrator, etc. can be used. In the aspect of miniaturization, there are also those that adopt the radial vibration and bending vibration of disc vibrator. Ultrasonic cleaning has been more and more widely used in various industries, such as industry, agriculture, household equipment, electronics, automobile, rubber, printing, aircraft, food, hospital and medical research.

Working Principle

When voltage acts on piezoelectric ceramics, mechanical deformation will occur with the change of voltage and frequency. On the other hand, when piezoelectric ceramics are vibrated, an electric charge will be generated. Using this principle, when an electrical signal is applied to a vibrator composed of two piezoelectric ceramics or a piezoelectric ceramic and a metal sheet, the so-called double piezoelectric chip element, ultrasonic waves will be emitted due to bending vibration. On the contrary, when ultrasonic vibration is applied to the dual piezoelectric chip element, an electrical signal will be generated. Based on the above functions, piezoelectric ceramics can be used as ultrasonic sensors.
