Shanghai Haozhuang Instrument Co., Ltd. has developed the Haozhuang (LNB) brand ultrasonic cleaning machine, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable How to complete the cleaning work with ultrasonic waves Ultrasonic cleaning uses the socialization, acceleration and direct flow of ultrasonic waves in the liquid to directly and indirectly affect the liquid and dirt, so that the dirt layer is dispersed, emulsified and stripped to achieve the purpose of cleaning . In the ultrasonic cleaners currently used, cavitation and direct flow are used more often. (1) Cavitation: Cavitation is the transmission of ultrasonic waves to the liquid at a frequency of more than 20,000 times per second compressive force and interactive pressure reduction. During pressure reduction, the phenomenon of vacuum nuclear cluster bubbles is generated in the liquid. When the compression force is applied, the vacuum nuclear cluster bubbles generate a strong impact force when crushed by pressure, thereby peeling off the dirt on the surface of the object to be cleaned, thereby achieving precision Washing purpose. ★ In the ultrasonic cleaning process, the bubbles that can be seen by the naked eye are not vacuum nuclear group bubbles, but air bubbles, which inhibit the cavitation effect and reduce the cleaning efficiency. Only when the air bubbles in the liquid are completely removed, the cavitation vacuum nuclear group bubbles can achieve the best effect. (2) Straight flow: The phenomenon that ultrasonic waves flow in the liquid along the direction of sound propagation is called straight flow. When the intensity of the sound wave is 0.5W / cm2, the naked eye can see the straight flow, and the flow is perpendicular to the vibration surface, and the flow velocity is about 10cm / s. Through this direct flow, the oily dirt on the surface of the object to be cleaned is stirred, and the cleaning liquid on the surface of the dirt also generates convection. Great effect. (3) Acceleration: The acceleration produced by the pushing of liquid particles. For the ultrasonic cleaner with higher frequency, the cavitation effect is very insignificant. At this time, the cleaning mainly depends on the ultra-precision cleaning of the dirt by the acceleration of the liquid particles under the ultrasonic impact particles. The structure of the ultrasonic cleaning machine: The ultrasonic cleaning machine is mainly composed of an ultrasonic cleaning tank and an ultrasonic generator. The ultrasonic cleaning tank is made of high-quality stainless steel with good elasticity and corrosion resistance, and an ultrasonic transducer vibrator is installed at the bottom; the ultrasonic generator generates high frequency and high voltage, which is transmitted to the transducer through the cable connection line, and the transducer and the vibration plate together High-frequency resonance occurs, so that the solvent in the washing tank is cleaned by ultrasonic waves. The principle of ultrasonic cleaning The principle of sound cleaning is the high-frequency oscillation signal emitted by the ultrasonic generator, which is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium. The ultrasonic waves in the cleaning solvent are radiated forward and densely in the cleaning solution Tens of thousands of tiny bubbles are generated by flowing the liquid. The tiny bubbles (cavitation nuclei) existing in the liquid vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles grow rapidly and then close suddenly. Shock waves are generated when closed, and thousands of atmospheric pressures are generated around them, destroying insoluble dirt and dispersing them in the cleaning liquid. When the group particles are wrapped in oil and adhere to the surface of the cleaning article, the oil is emulsified and solid particles That is detached, so as to achieve the purpose of cleaning the surface of the cleaning member. Due to the inherent penetrating power of ultrasonic waves, it is possible to clean all kinds of objects with complex surfaces and special shapes. It has a good cleaning effect on small holes and gaps. Air Cushion Puff,Cushion Puff,Cushion Foundation Puff,Makeup Puff DONGGUAN YACAI COSMETICS CO.,LTD. , https://www.yacaicosmetic.com
