Ultrasonic cleaning is based on ultrasound in the cleaning of the liquid medium in the transmission of the unique "cavitation effect" of the physical role of the ultrasonic generator to produce higher than 20KHz ultrasonic frequency of high-power electrical energy, the ultrasonic transducer by the inverse piezoelectric effect of the conversion of the high-power ultrasonic energy is transmitted to the cleaning medium. When the intensity of the ultrasonic acoustic field over the cavitation valve of the cleaning medium, the cleaning fluid medium due to the ultrasonic negative pressure and the rapid generation of countless dilated "cavities", and in the ultrasonic positive pressure "cavities" is strongly compressed, "cavities "up to thousands of atmospheric pressure inside and burst, this is unique to ultrasound "cavitation effect" (or "cavity effect"), "cavitation effect" Formation of microscopic strong shock waves and high-speed jet acting on the surface of the object to be cleaned, so that the dirt quickly crushed, stripped to achieve high quality, high efficiency cleaning purposes. Ultrasonic tens of thousands of times per second to negative pressure expansion and positive pressure strong compression burst countless "cavities", high-frequency generation of countless microscopic shock waves, so that ultrasonic for the cleaning fluid immersed in the complex internal and external surface shape of the object to be washed, slits, deep holes, corners, dead ends and other parts of the unique and excellent cleaning ability and cleaning efficiency is unparalleled and other methods. Alternative. For the different nature of the dirt choose the appropriate cleaning additives, ultrasonic cleaning of various oil, polishing cream, rust, oxides, blood, fingerprints, paint, tea scale, carbon, dust, nuclear pollution and other dirt.
