Advantage and Use Method about the Plasma Surface Treatment Machine

Plasma cleaning machine is a high-tech product in the cleaning industry. It needs professional training and guidance before use. Therefore, the method of use is very strict and requires professional personnel. This chapter introduces the use of plasma cleaning machine in detail. By the way, help everyone understand the advantages of plasma cleaners.

How to use the plasma cleaner:

The use of plasma cleaners requires professional training, so we will focus on understanding the operation of plasma cleaning equipment in this article.

Depending on the application, plasma cleaning equipment of various configurations can be selected, and the process flow can be optimized by selecting different kinds of gases, adjusting the characteristic parameters of the device, etc., but the basic structure of the plasma cleaning device is roughly the same. The general device may be composed of a vacuum chamber, a vacuum pump, a high frequency power source, an electrode, a gas introduction system, a workpiece conveying system, and a control system. The commonly used vacuum pump is a rotary oil pump. The high frequency power supply usually uses 13.56 M Hz radio waves. The operation of the equipment is as follows:

(1) The workpiece to be cleaned is sent to the vacuum chamber and fixed, the running device is started, and the exhaust is started, so that the vacuum in the vacuum chamber reaches a standard vacuum of about 10 Pa. The general exhaust time takes approximately 2 minutes.
      (2) A gas for plasma cleaning was introduced into the vacuum chamber, and the pressure was maintained at 100 Pa. Depending on the cleaning material, gases such as oxygen, hydrogen, argon or nitrogen may be used.
      (3) A high-frequency voltage is applied between the electrode in the vacuum chamber and the grounding device to cause the gas to be broken down, and ionization and plasma generation occur by glow discharge. The plasma generated in the vacuum chamber is completely covered in the workpiece to be processed, and the cleaning operation is started. The general cleaning process lasts for tens of seconds to a few minutes.
      (4) After the cleaning is completed, the high-frequency voltage is cut off, and the gas and the vaporized dirt are discharged, and at the same time, air is blown into the vacuum chamber, and the air pressure is raised to an atmospheric pressure.
So what are the advantages of using a plasma cleaner in the cleaning industry?

Advantages of plasma cleaner:

(1) After the plasma cleaning, the object to be cleaned is already very dry, and it is not necessary to be dried to be sent to the next process.
       (2) Do not use the harmful solvent of trichloroethylene ODS, and it will not produce harmful pollutants after cleaning. It is a green cleaning method that is beneficial to environmental protection.
       (3) The plasma generated by the high frequency of the radio wave range is different from the direct light such as laser light, and its directivity is not strong, so it can penetrate into the micro-holes and recesses of the object and complete the cleaning task, so it is not necessary to consider too much. The effect of the shape of the object being cleaned, and the cleaning effect on these difficult-to-clean parts is similar to or better than that of cleaning with Freon.
       (4) The entire cleaning process can be completed in a few minutes, so it has high efficiency.

 (5) Plasma cleaning requires a controlled vacuum of about 100 Pa, which is easily achieved in actual factory production. The cost of the equipment is not high, and the cleaning process does not require the use of expensive organic solvents, so its operating costs are lower than the traditional cleaning process.
        (6) Since the cleaning liquid is not required to be transported, stored, discharged, etc., the production site is easy to maintain clean and hygienic.
        (7) The biggest technical feature of plasma cleaning is that it can process different substrates regardless of the processing object, whether it is metal, semiconductor, oxide or polymer materials (such as polypropylene, polyvinyl chloride, according to tetrafluoroethylene, Polyesters such as polyimides, polyesters, and epoxy resins can be handled well by plasma, and therefore, they are particularly suitable for substrate materials which are not heat resistant and solvent resistant. It is also possible to selectively clean the entire, partial or complex structure of the material.
       (8) While completing the clear decontamination, it is also possible to change the surface properties of the material itself, such as improving the wetting properties of the surface and improving the adhesion of the film, which is very important in many applications.

Plasma cleaning machines are now widely used in various industries, so its outstanding features and advantages are increasingly valued by people. It is becoming more and more common in all walks of life. If you are interested in plasma cleaning machine, please contact us.
