How it Works Ultrasonic cleaning works by producing sound waves in liquids. The waves consist of both high- and low-pressure Fronts. The low-pressure fronts are small enough to cause bubbles to form. The high-pressure fronts cause the bubbles to collapse. The expanding and collapsing bubbles loosen contaminants on the part surface and the chemical cleaners either dissolve or segregate the free contaminants. As with sound waves in air, ultrasonic sound waves can be varied by both frequency (pitch) and amplitude (power). Higher frequencies will produce smaller bubbles and lower frequencies will produce larger bubbles. Larger bubbles will typically dislodge large particles and smaller bubbles small particles. Typical industrial systems are either 28kHz or 40 kHz, which can handle the particle sizes in the range of normal automotive cleaning. Ultrasonic cleaning systems with a much higher frequency are used in the computer industry where tiny particles need to be removed. Instantaneous high pressure of more than 1000p which constantly heat the surface of the subject and reach the purpose of complete cleaning. Because of its special design, this instrument has improved both dissolution and emulsifications in solution. Besides, this ultrasonic cleaner has great degassing effect without causing pollution to environment; therefore it has been widely used in machinery, electronics, medical, chemical tests and other industries. This ultrasonic cleaner series are ideal instruments used in professional fields such as electronic apparatus, semiconductor chips, circuit panel, optical lens, audio magnetic recording heads, etc. It is also widely applied in biochemical, chemical, and medical fields.
