(Summary description)According to the temperature of heavy particles in plasma, plasma can be divided into two categories, hot plasma and cold plasma. At 3×103K-3×104K, the thermodynamic equilibrium is basically reached, with a uniform thermodynamic equilibrium temperature, and the plasma state and the plasma state can be determined by Maxwell's thermodynamic equilibrium velocity distribution, Boltzmann particle energy distribution, Shaha equation and other methods. parameter. Thermal plasma has high energy density and is mainly used for material synthesis, spheroidization, densification and coating protection. In low temperature plasma, the temperature of heavy particles is only room temperature, while the temperature of electrons can reach thousands of degrees, so it is far away from the thermodynamic equilibrium state, such as glow discharge belongs to low temperature plasma. Cold plasma is mainly used for plasma etching, deposition and plasma surface decoration. The temperature of electric washing is a concern of many users. During electric washing, the flame of electric washing looks similar to the general flame. However, if the electric washing equipment adopts an intermediate frequency power supply, it has high power and strong energy, and the temperature without water cooling is also very high. If the washing material is not temperature resistant, pay attention to the temperature. The power supply of the plasma cleaning machine is commonly used 13.56KHz radio frequency power supply, which produces high plasma density, soft energy, and low temperature. , the intermediate frequency power is 40KHz, contrary to the radio frequency power supply, the plasma density is not high, but the power is large, the energy is high, and the high power is tens of KW. The temperature of the vacuum plasma cleaner discharge RF cleaner is similar to the usual indoor temperature. Of course, if the vacuum plasma cleaner is used all day, it still needs to add water to the cooling system. The average temperature of the plasma jet is between 200 and 250 degrees Celsius. If the distance and speed can be set correctly, the surface temperature can reach 70-80℃. This process is suitable for cleaning various standard products (metals, ceramics, glass, plastics, elastomers, etc.). Generally, a jet plasma cleaning device is used, and it can also be applied to a plasma cleaning device on an assembly line. Due to the continuous operation of the assembly line , the material stays under the nozzle for a long time. Nitrogen can also be used for some jet plasma cleaning due to its ability to lower the plasma temperature. It should be noted that there is another product in the plasma cleaning machine called corona. In fact, corona is also a classification of plasma cleaning machines. The washing temperature of the corona machine is generally higher, and the washing temperature of the corona machine is similar to that of the jet plasma. Sometimes materials that are not resistant to high temperature are also cleaned with nitrogen. In fact, there is no need to worry too much about temperature. The current plasma cleaning machine can adjust the temperature well, so that the material cleaning can achieve the desired effect
