Why does plasma cleaning machine emit bright colors?

Why does the seismograph plasma cleaning machine produce light? The reason is that the seismograph plasma cleaning machine uses different gases for process treatment during use. Under low voltage conditions, a glow discharge is formed by adding working voltage to two flat electrodes. This is a relatively stable self-sustaining self discharge, with a discharge working current in the mA range. The plasma cleaning machine is equipped with two electrodes in a sealed container to form an electric field, and a certain vacuum is achieved through a vacuum pump. When the gas becomes thinner, the distance between molecules and the free movement of molecules or ions will become longer, and then plasma will be formed through electric field collision. When phases react in different directions, ions form plasma, which is known as glow discharge treatment.

Electrons and covalent bonds move towards the anode and anode, respectively, under the action of a bipolar electric field, accumulating near the poles and forming a space charge region. Due to the much lower drift speed of covalent bonds compared to electrons, the electron density in the covalent bond space charge region is much higher than that in the electron space charge region, resulting in the entire inter electrode working voltage being almost concentrated in a narrow region near the negative electrode. In the case of normal self discharge in glow discharge, the working voltage between the two poles does not change with the working current, which is also a prominent feature of glow discharge.

The seismograph plasma cleaning machine is an ionized gas substance composed of negatively charged particles (negative ions, electrons), positively charged particles (positive ions), and uncharged particles. It is usually parallel to the solid, liquid, and gas states of matter, known as the fourth state of matter. By discharging or heating gas, sufficient energy is obtained from the outside to convert electrons in gas molecules or atomic orbitals into free electrons. In the chemical industry, the choice of plasma surface treatment technology can create relevant chemical changes, generate various products, and form thin films.

Seismometer - In the process of using a plasma processing machine, different gases are used for process processing, and the energy levels of various gases have different energy conversions. Different process gases exhibit different luminescent characteristics, resulting in different color characteristics. Each gas emits different wavelengths of light during the electron transition process, so different colors of light can be seen. Of course, when you increase the power, it appears as white light because there are too many photons.

For the gases used in the production process of plasma cleaning machines, typical colors include: CF4: blue SF6: light blue SIF4: light blue SICL4: light green H2: light green H2: pink 02: light yellow N2: red He: red purple Ne: brick red Ar: deep red plasma cleaning machine. The bright colors produced can not only be used to identify process gases, but also to evaluate whether there are pollutants in the process gases.

Therefore, plasma cleaning machines can remove organic compounds, surface adhesion layers, and film layers on the surface of workpieces that are invisible to the human eye. They can solve the problem of adhesion on the surface of workpieces, such as surface activation treatment (polymers and raw materials are activated to create an ideal bonding surface on the workpiece surface for coating, printing, welding, and spraying), and surface polymerization treatment. Simple PVD coatings cannot solve all wear problems. Therefore, plasma cleaning equipment should be selected to obtain new surface structures through sub micro height connected thin film precipitation, and strengthen spraying and surface treatment.
