The principle of ultrasonic cleaning machine:
The principle of an ultrasonic cleaning machine is mainly to convert the acoustic energy of the ultrasonic frequency source into mechanical vibration through the transducer. The ultrasonic waves are radiated into the cleaning liquid in the tank by the cleaning trough wall. Due to the radiation of ultrasonic waves, the microspheres in the liquid in the groove can remain vibrated under the action of sound waves. This can break the adsorption of the surface of the dirt and cleaning parts. The fatigue damage and stripping of the dirt layer are then caused. The vibration of the bubbles scrubs the solid surface. It utilizes liquid ultrasonic cavitation effects to destroy and affect contaminants on the surface of the object. Some applications also require an auxiliary chemical cleaning agent to achieve the purpose of cleaning.
Application of ultrasonic cleaning machine:
Ultrasonic cleaning machine is widely used in surface spraying treatment industries, machinery industry, electronics industry, medical industries, semiconductor industries, watch jewelry industries, optical industries, textile printing, and dyeing industries. The application of the ultrasonic cleaning machine is as follows.
1. Surface spray treatment industry: (dirt of cleaning: oil, mechanical shavings, abrasive, dust, polishing wax)
Remove the carbon deposit before electroplating, remove the oxide, remove the polishing paste, remove oil and rust, ion plating cleaning, phosphating treatment, metal workpiece surface activation treatment, etc. Stainless steel polishing products, stainless steel tools, cutlery, tools, locks, illumination, jewelry before coating, cleaning before electroplating.
2. Mechanical industry: (dirt of cleaning: cutting oil, abrasive, iron filings, dust, fingerprint) removal of anti-rust oil, gas cleaning, remove rust from mechanical components. Engines, engine components, gearboxes, dampers, shaft tiles, nozzles, cylinders, valve bodies, careers, and automotive parts and primer. Reflections of rust, phosphating; filter, piston components, filters dredging and cleaning, etc. Precision mechanical components, compressor components, camera components, bearings, hardware components, molds. Especially in the railway industry, it can clean dirt and oil on the air conditioning of train compartments.
The principle of the plasma cleaning machine:
The plasma cleaning machine employs a gas as a cleaning medium. It effectively avoids secondary pollution caused by liquid cleaning media to wash objects. The plasma cleaning machine is connected to a vacuum pump. The plasma in the cleaning tank is reacted and ash. Short-time cleaning can be thoroughly cleaned with organic pollutants. Pollutants are exhausted by a vacuum pump. The degree of cleaning can reach the molecular stage.
The plasma cleaner can also change the performance of certain material surfaces as needed in addition to the ultra-cleaning function. Plasma acts on the surface of the material, the chemical bonds of recombinant surface molecules. This can form a new surface characteristic. For some of the materials having special purposes, the glow discharge in the supernatant is not only enhances the adhesion, compatibility, and permeability of these materials but also sterilized them.
Plasma cleaner is widely used in optical, optoelectronics, electronics, material science, life science, polymer science, biomedicine, microfluidics. Application areas of plasma cleaning machines: Plasma cleaning machines are widely used in LED, LCD, LCM, mobile phone accessories, laptop buttons and housings, optical components, optical lenses, electronic chips, integrated circuits, hardware, precision parts, plastic products, creatures, medical vessels, wafers. The surface activation effect after plasma treatment is good. The water-improving effect of the object is also very good.
The plasma cleaning technique is characterized by treating metal, semiconductors, oxides, and polymeric materials such as polypropylene, polyester, polyimide, polyvinyl chloride, epoxy resin. Even polytetrafluoroethylene can also be treated well. It is possible to achieve a clean, partial, and complex structure.
Conclusion: When you need to clean the precision products but are not suitable for liquid cleaning, it is recommended to use a plasma cleaning machine. If you can use liquid cleaning, you can weigh the ultrasonic cleaning machine or a plasma cleaning machine. Some cleaning processes use ultrasonic cleaning even in the previous paragraph and then plasma cleaning in the latter paragraph. There is no 100% good or bad cleaning method, just select the right one that meets the process requirements.
