1. What is plasma?
Plasma is a high-energy unstable state. Using this high-energy and unstable state, plasma has a variety of applications.
2. What are the components of the plasma cleaner?
The plasma cleaning machine is mainly composed of two parts: First, the plasma generator, which is composed of integrated circuits, operation control, plasma generation power supply, gas source processing, safety protection, etc. The second is the plasma processing device, which is composed of excitation electrodes, excitation gas paths, and so on.
3. What are the reaction principles of plasma cleaners?
Plasma cleaners mainly rely on plasma to react with the surface of the material to achieve the purpose of modification, but generally speaking, there are two main reactions that can occur between plasma and the surface of the material. One is to use free radicals to make chemical reactions. The other is to rely on plasma for physical reaction.
4. What is the chemical reaction principle of the plasma cleaner?
The gases commonly used in chemical reactions of plasma cleaners are hydrogen (H2), oxygen (02), methane (CF4), etc. These gases react in the plasma to form highly active free radicals. The equation is: these free radicals will Further react with the surface of the material.
The reaction mechanism is mainly to use the free radicals in the plasma to chemically react with the surface of the material. When the pressure is higher, it is more beneficial to the generation of free radicals. Therefore, if the chemical reaction is to be the mainstay, it is necessary to control the higher Pressure comes to react.
5. What is the physical reaction principle of the plasma cleaner?
The physical reaction is mainly to use the ions in the plasma to make pure physical impacts to knock off the atoms on the surface of the material or the atoms on the surface of the attached material. Because the average free radicals of the ions are lighter and longer when the pressure is low, some energy accumulates Therefore, during physical impact, the higher the energy of the ions, the more they will impact. Therefore, if the physical reaction is to be the mainstay, a relatively high pressure must be controlled to carry out the reaction, so that the cleaning effect is better. In order to further explain each The effect of this kind of equipment cleaning.
6. What is the principle of plasma cleaning machine?
The mechanism of the plasma cleaning machine mainly relies on the "activation" of the active particles in the plasma to achieve the purpose of removing stains on the surface of the object. In terms of reaction mechanism, plasma cleaning usually includes the following processes: inorganic gas is excited into a plasma state; gas phase substances are adsorbed on the solid surface; adsorbed groups react with solid surface molecules to form product molecules; product molecules resolve to form a gas phase; reaction The residue is detached from the surface.
7. What are the characteristics of the plasma cleaner?
Plasma cleaning has the following characteristics: easy to use numerical control technology, high degree of automation; with high-precision control device, time control accuracy is high; correct plasma cleaning will not produce damage on the surface, and the surface quality is guaranteed; It is carried out in a vacuum, does not pollute the environment, and ensures that the cleaned surface is not polluted twice.
8. How to choose a suitable plasma cleaner？
Buying what suits you is the best choice! Zhenyi shares plasma cleaning machine manufacturer, has: various types of cleaning machines and complete line solutions. According to the characteristics of cleaning products, the following aspects need to be considered:
1. Is it a complex shape or a flat surface?
2. How many degrees Celsius can the processed sample withstand the temperature?
3. According to production needs, process and efficiency requirements, is there a need for supporting production lines?
