Powder plasma cleaning machine can achieve the purpose of cleaning and modification

　Powder plasma cleaning machine is a device that uses plasma technology to modify and clean the surface of materials. Plasma is a gas state composed of charged particles, neutral particles and free radicals, with high energy and chemical activity. During the cleaning process, the high-energy particles in the plasma react with the pollutants on the surface of the material, thereby achieving the purpose of cleaning and modification.

Powder plasma cleaning machine mainly consists of the following parts:

1. Vacuum system: including vacuum pump, vacuum gauge and vacuum chamber. The function of the vacuum system is to exclude air and create conditions for the generation of plasma.

2. Gas supply system: including gas cylinders, gas flowmeters and gas pipelines. The gas supply system is responsible for delivering working gases such as argon, oxygen, nitrogen, etc. to the vacuum chamber.

3. RF generator: used to generate high-frequency electromagnetic fields and excite gas molecules to generate plasma.

4. Matching network: used to adjust the output impedance of the RF generator to match the impedance of the load (i.e. plasma), thereby improving the energy transmission efficiency.

5. Electrode system: including two parallel upper and lower electrode plates, used to carry samples and apply RF voltage.

6. Control system: including control cabinet, operation panel and software. The control system is responsible for the operation and monitoring of the entire equipment.

The working principle of the powder plasma cleaning machine is as follows:

1. Place the powder sample to be cleaned on the sample rack in the vacuum chamber.

2. Start the vacuum system to extract the air in the vacuum chamber to achieve a certain vacuum degree.

3. Deliver working gas, such as argon, oxygen, nitrogen, etc., to the vacuum chamber through the gas supply system.

4. Start the RF generator to generate a high-frequency electromagnetic field to excite gas molecules to generate plasma.

5. The high-energy particles in the plasma react with the pollutants on the surface of the material to achieve the purpose of cleaning and modification.

6. After cleaning, turn off the RF generator, stop the gas supply, gradually restore the pressure in the vacuum chamber, and take out the cleaned sample.

The powder plasma cleaning machine has the following characteristics:

1. Good cleaning effect: Plasma has high energy and chemical activity, which can effectively remove organic, inorganic, oxide and other pollutants on the surface of the material.

2. Fast cleaning speed: The cleaning process is usually completed within a few minutes, which greatly improves production efficiency.

3. Environmentally friendly: No chemical reagents are required in the cleaning process, no harmful waste is generated, and no pollution is done to the environment.

4. Strong adaptability: The cleaning technology is suitable for surface treatment of various materials, such as metal, ceramic, plastic, glass, etc.

5. Easy to operate: The automatic control system is adopted, which is easy to operate and easy to master.
