Ultrasonic wave propagation in liquid, the liquid cleaning tank together at ultrasonic frequency vibrations, liquid cleaning tank and has its own natural frequency of vibration, the vibration frequency of the sound frequency, so people can hear the hum. With the continuous development of the cleaning industry, more and more industries and enterprises to use the ultrasonic cleaning machine. High-frequency oscillation signal of ultrasonic cleaning machine principle issued by the ultrasonic generator, and transmitted to the media by the transducer into high frequency mechanical oscillations - cleaning solvents, ultrasonic cleaning fluid density and white in the forward radiation, so liquid flow generated tens of thousands of tiny bubbles 50-500μm in diameter, and the presence of tiny bubbles in the liquid under the action of the vibration of the sound field. These bubbles longitudinal ultrasonic wave propagation in the negative pressure zone formation, growth, and positive pressure zone, when the sound pressure reaches a certain value, the bubble increases rapidly, then suddenly closed. And generating a shock wave in the bubble closed, resulting in thousands of atmospheres around it, and allow them to undermine the insoluble contaminants dispersed in the cleaning solution, when bodies were wrapped in oil and particles adhered to when cleaning the surface, the oil is emulsified, solid particles and detachment, cleaning member so as to achieve the purpose of purification. In this is called "cavitation" effect of the process, bubbles can form closed hundreds of degrees of heat and pressure over 1000 high-voltage transient. 1 2 editing process, cleaning polishing after polishing an optical glass production to determine its processing efficiency and surface quality (appearance and precision) is an important step. Polishing step of main pollutants abrasive powder and asphalt, a few companies have paint flakes process. Wherein the different type abrasives, generally based on alkali metal ceria-based oxide. Depending on the material and precision grinding of the lens, choose different types of abrasive powder. Asphalt used in the milling process is protective to prevent complete mirror polishing scratches and corrosion. Cleaning equipment after grinding divided into two kinds: one of the main use of organic solvent cleaning agents, another major use of semi-water-based cleaning agent. 2, the main pollutants cleaned before coating the coating before cleaning is required core oil (also known as oil milling, seeking core also weighed core, core, means for obtaining a predetermined radius and a core precision and optional step), fingerprints, dust, etc. Since the lens coating process is extremely strict cleanliness requirements, and therefore cleaner choice is very important. In considering some kind of cleaning agent cleaning capabilities, while also taking into account the problems he and other aspects of corrosion. Frequency ultrasonic cleaning machine operating frequency is very low (in the range of human hearing) will produce noise. When the frequency is less than 20kHz, working noise only becomes large, and may exceed the limits specified in the Occupational Safety and Health Act or other regulations safe noise. In high power to remove dirt without regard to the application of the surface damage, usually select from 20kHz to 30kHz range within a lower frequency of cleaning. Cleaning frequency within the frequency range is often used for cleaning large, heavy parts or workpiece high density material. Low frequency is typically used for cleaning small, precision parts, or remove tiny particles. High frequency is also used for the application is not allowed to damage the surface. Use high frequency to improve cleaning performance in several ways. As frequency increases, the number of cavitation bubbles increases linearly, resulting in more and more intense shock waves so that it can enter into a smaller gap. If power is kept constant, smaller cavitation bubbles, a corresponding reduction in the release of energy, thus effectively reducing the damage to the workpiece surface. Another advantage of the high-frequency viscous boundary layer is reduced cavitation ultrasonic cavitation is more than twenty thousand times per second with compression force and reduce high frequency conversion system pressure interactivity to liquid transmission. When reduce pressure to produce liquid bubble nuclei vacuum phenomenon in the compression force, the vacuum bubble nuclei produced by the impact of a strong pressure crushed, thereby stripping the dirt surface to be cleaned to achieve precision Wash purpose straight flow along the propagation direction of the ultrasonic sound generated in the liquid flow phenomenon known as a straight flow. Acoustic intensity 0.5W / cm2, the naked eye can see straight into the stream, perpendicular to the plane of vibration generated flow, flow rate of about 10cm / s. This straight flow to be cleaned so that the surface of micro-oil dirt is stirred, the cleaning liquid dirt surface convection also dissolved dirt dissolving solution was mixed with the new, dissolve faster, plays for dirt removal big role. Liquid particle acceleration driven acceleration produced. For higher frequency ultrasonic cleaning machine, cavitation on the very significant, and this time depends mainly on cleaning liquid particle acceleration under the impact of ultrasound on the dirt particles ultra-precision cleaning.
