5L Vacuum Plasma Cleaning Machine Instructions
1, Equipment Description: Part of the plasma power supply, vacuum system, inflation system, automatic control system.The basic principle of work is that under vacuum, the plasma can ionize the gas under the control and qualitative methods, and the vacuum pump is used to vacuum the working chamber to a vacuum of 30-40 Pa, and then the gas is ionized under the action of the high frequency generator. Forming a plasma (the fourth state of matter), its remarkable feature is a high uniform knife glow discharge, which emits color visible light from blue to deep purple according to different gases, and the material processing temperature is close to room temperature.These highly active microparticles interact with the treated surface to provide various surface characteristics such as surface hydrophilicity, water repellency, low friction, high cleaning, activation, and etching.
2, plasma processing advantages:
1. Environmental protection technology: The plasma action process is a gas-solid phase dry reaction, which does not consume water resources, does not require the addition of chemicals, and has no pollution to the environment.
2. Wide applicability: It can be processed regardless of the type of substrate to be processed, such as metals, semiconductors, oxides and most polymer materials.
3. Low temperature: close to normal temperature, especially suitable for polymer materials, longer storage time and higher surface tension than corona and flame methods.
4. Strong function: only involves the shallow surface of polymer material (10 -1000A), which can give it one or more new functions while maintaining its own characteristics;
5.Low cost: simple installation, easy operation and maintenance, continuous operation, often several bottles of gas can replace thousands of kilograms of cleaning fluid, so the cleaning cost will be much lower than wet cleaning.
6. Full process controllable process: All parameters can be set by computer and data recording for process quality control.
7. The geometry of the treatment is unlimited: large or small, simple or complex, and parts or textiles can be processed.
Model:MD-5L
A small plasma cleaner refers to a plasma cleaner with a volume below 10 liters and a radio frequency power supply below 500 watts. According to different cleaning and processing requirements, the frequency is divided into 40KHz, 13.56MHz and 2.54GHz. In comparison, when operating at 13.56MHz RF frequency, the matching is simple, and the RF power supply provided is highly efficient, so it is popular in conventional material handling and cleaning applications.

1,Basic structure of the small plasma cleaner
1),RF power supply: RF source, RF regulation, power amplification, power regulation, power output, output protection, plasma electrode, temperature protection.
2),System control part: digital automatic control, I/O control, vacuum A/D detection, pulse width ratio D/A adjustment, parameter memory, clock setting.
3),Vacuum and gas path parts: vacuum system, applied gas, flow regulation, return air and piping For small plasma cleaners, because the RF power is small, the RF power supply and control are assembled in a single chassis, one is to reduce the space occupation, the other is easy to operate and place, and compared with the large cleaning machine, from the detection The function and control functions are set as concise as possible.

Overall appearance treatment process, rack door paint, durable, scratch-resistant, aluminum alloy automatic door: oxidation treatment, sand blasting, smooth high-grade, stainless steel cavity internal surface treatment bright, easy to clean, circuit design current overload protection, modular circuit, Easy and quick maintenance, PLC man-machine interface, convenient, concise, precise timing, manual, automatic, vacuum pressure can be operated, tumbler rubber foot cup, automatic balancing machine, shock absorption,
2,Work flow and technical conditions of the small plasma cleaner
The system starts the RF source operation under the condition of setting the vacuum degree,
generates 40KHz RF pulse, and sends it to the output stage through power amplification. The output
stage has three functions: one is isolation, the other is boost, and the third is matching. A radio
frequency pulse with sufficient energy is used to excite the high voltage plate to generate plasma
Power level control and adjustment can be set digitally in the system or manually.
The adjustment of the power is essentially realized by changing the width of the RF pulse. The schematic diagram of the two RF pulse coordinates in the above figure illustrates the principle of power regulation.
The RF pulse output under the ideal conditions mentioned here is expressed regardless of the loss of the device and the magnetic material. The actual RF pulse waveform is distorted, but when the distortion is too large, the output will be made. The effective power is greatly reduced, not only does it not normally generate plasma, but it also burns the equipment. In addition, excessive harmonic pulse components can also cause a decrease in RF efficiency, causing the device to malfunction or even burn out. Therefore, the technical requirements of the plasma cleaner for the RF power supply are very high.
