Q:How choose the material?
A:The most common material is I304 stainless steel. But 304 stainless steel is not resistant to acid and alkali, can only be used in clear water or ordinary cleaning agent.If there is acid and alkali cleaning solution, must be made of 316L stainless steel, of course, 316L only alkali resistance, for acidic. PH value is greater than 5, 316 stainless steel can afford, solvent under less than 5, 316 stainless steel is easy to perforation, PH in 2-3 strong acid, can only choose titanium plate production.
Q: What is the thickness of the stainless steel plate?
A: No Matter what stainless steel immersible transducer or cleaning machine, not the thicker the better, not the thinner the better. The thickness of 2.0 mm, it is more economical, and good ultrasonic effect. For the low frequency 28 kHz and 25khz. 2.0 thickness of stainless steel plate is more easy breakdown.2.5mm thickness is the most commonly used .3.0mm thickness is durable, not easy to be worn, So the thickness needs to be selected according to the frequency and solvent and cost 3/18
Q: How to choose a suitable frequency?
Choose 17khz to 200khz according to different cleaning workpiece and the cleaning process. The lower frequency of ultrasonic, the more vibration amplitude, the higher the frequency, the more precise the cleaning. Such as hardware, circuit boards, electronic cleaning, generally use 28KHZ, Wash dishes 28KHZ or 25KHZ; Optical lenses, etc., can be used with 40KHZ, or a higher frequency of 68KHZ, or even 80KHZ, 100KHZ, and can be used in a variety of frequencies. First, wash first and then rinse. 4/18
• The principle of the Ultrasonic submersible transducer is the high-frequency oscillation signal sent by the ultrasonic generator, which is converted to high-frequency mechanical oscillation by transducers and then propagated to the medium.
• The forward and backward ultrasonic waves in the cleaning solution. The liquid flows and produces tens of thousands of tiny bubbles. The tiny bubbles (cavitation nucleus) existing in the liquid vibrate under the action of the sound field.
• When the sound pressure reaches a certain value, the bubble grows rapidly and then closes suddenly. When the bubbles close Shock waves are generated around it to produce thousands of atmospheric pressure, destroy the insoluble dirt and make them dispersed in the cleaning fluid, when the group of particles is wrapped in oil and attached to the cleaning surface, the oil is emulsified, solid particles that Off, so as to achieve the purpose of cleaning parts surface purification.
