ultrasonic sonochemistry machine

Ultrasonic cleaning is based on the effect of ultrasonic cavitation, ultrasonic sonochemistry machine when the ultrasonic wave after the formation of air bubbles burst (closed) moment can produce more than 1000 atmospheric pressure, the instantaneous high pressure strong shock produced by continuous surface of object, make a crack in the surface and flake dirt quickly, thus achieve the goal of surfaces clean purification.
By ultrasonic cleaning machine ultrasonic generator of high frequency oscillation signal, through the transducer converts the high frequency machinery vibration and spread to the medium, ultrasonic cleaning machine in the cleaning fluid density are asked to forward radiation, when the sound waves, atmospheric pressure, the pressure reaches a certain produce tens of thousands of tiny air bubbles, the bubbles in the negative pressure of ultrasonic longitudinal transmission area formation, growth, and in positive pressure area closed quickly. This phenomenon is called ultrasonic "cavitation effect", the pressure needed to generate bubbles when called ultrasonic cavitation threshold ".
Artifacts in oil removal, cleaning, washing, table, phosphating process such as penetration welding cracks in liquid is difficult to discharge, and water can't completely clear clean, under the condition of damp and hot inclusions easily to artifacts yellowing, rust. If the residual liquid in the drying process can't completely dry solid, then powder coating with high temperature drying, weld residual liquid due to the effect of thermal expansion will seep, affect the combination of coating and the metal surface, cause the loss of adhesion of coating to even out.
Domestic start later, in the field of automatic ultrasonic ultrasonic cutting machine cleaning machine treatment in the early 1950 s that only a few hospitals in ultrasonic treatment, starting from the first in Beijing in 1950 with 800 KHZ frequency of ultrasonic therapy apparatus treatment of various diseases, and 50 s promotes gradually, and with the domestic equipment. Open literature reports beginning in 1957. In the 70 s with various domestic ultrasonic therapeutic apparatus, ultrasonic therapy reach national each big hospital.
More than 40 years, the national each big hospital has accumulated a considerable amount of data and rich clinical experience. Especially in the early 1980 s of the ultrasound in vitro mechanical wave lithotripsy and ultrasonic surgical, is a major breakthrough in the history of stone therapy. Today ultrasonic cleaning machine is applied in the international scope. High intensity focused ultrasound noninvasive surgery, has made ultrasonic treatment occupy the important position in modern medical technology. In the 21st century focusing ultrasound (HIFU) surgery has been hailed as the 21st century the latest technology for the ultrasonic dispersion machine treatment of tumor.
In physics found piezoelectric effect and inverse piezoelectric effect, the people to the use of ultrasonic electronics technology solution, quickly opened the history of development and promotion of automatic ultrasonic cleaning machine technology. As we study of ultrasonic constantly, we gradually master the application of ultrasonic, he has gradually be applied to the life, such as ultrasonic washing machine, and application in medical treatment.
