The bottleneck and challenge of the atmospheric pressure plasma machine-Guoxing Technology does not forget the original intention to move forward. The generation of plasma requires the use of electromagnetic fields to provide energy to accelerate electrons. Therefore, the electrons absorb energy in the electric field. If the energy accumulation is high enough, it will It is enough to cause the collision of gas molecules to produce ionization and increase the number of electrons. The new electrons and the original electrons absorb energy further, generating more electrons, and forming a chain reaction. Therefore, the electrons need to absorb energy in the electric field and accumulate enough to dissociate the gas to generate plasma. The highest kinetic energy of electrons = the accumulation of work done by the electric field on the electrons        = F × d        = Q × ε × λ F: force, d: distance, q: electron charge amount, ε: electric field strength, λ: mean free path of electrons Because the mean free path of electrons is much longer than that of other particles, low-voltage electric pastes can obtain sufficient energy to dissociate other gases. However, when the pressure is one atmosphere, the mean free path of electrons is difficult due to frequent collisions of gas molecules and very short mean free paths. It accumulates enough energy to dissociate gas molecules, so plasma cannot be started. At this time, there are two ways to generate plasma: (1) Increase the potential of the external power supply to more than a few thousand volts, so that the electrons can obtain sufficient energy within the limited distance accumulation between two collisions to carry out the ionization reaction to generate plasma; (2) Provide a large amount of electric current to heat the gas molecules to form high-temperature plasma. In addition, compared with low-voltage plasma, atmospheric pressure plasma often encounters various unique discharge instability problems, that is to say, atmospheric pressure plasma is easily confined to a specific local area, so it is necessary to use expensive but easy-to-discharge cyanide gas Or helium can be used as a process gas to overcome it. How to establish a cheap, large-area and high-efficiency atmospheric pressure plasma technology is still a problem that the world is trying to solve, and it is also the most difficult technical bottleneck in the industry. Guoxing Technology has been studying these bottlenecks and challenges with great concentration, tirelessly, and strive for perfection, just for the original intention in my heart.
