What are the discharge areas of the atmospheric plasma surface cleaner

What are the discharge areas of the atmospheric plasma surface cleaner:
Atmospheric plasma surface cleaning machines that are widely used in general industry are all excited by electric fields and cooperate with different machines to generate the required plasma. What are the characteristics of the gas discharge process? What discharge areas are there?
Generally speaking, the discharge of the atmospheric plasma surface cleaning machine is divided into two types: self-sustained discharge and non-self-sustained discharge. When the external catalyzer is stopped, the discharge will continue to be used; the non-self-prepared catalyzer will stop using immediately. The following is the gas discharge situation in each area of the plasma cleaning machine.
Tangsheng discharge areas in Zone I and Zone II:
Tangsheng discharge is divided into two types: self-sustained and non-self-sustained. The Tangsheng discharge theory can be applied to the discharge types and discharge areas that are generated by the influence of electric fields, such as electrons and ions, which have obvious advantages compared with their own irregular thermal motions.
The transition zone of Zone III:
Fire is a transition form from non-self-sustained discharge to self-sustained discharge. Self-sustained discharge has many different properties and forms. The nature and form of discharge caused by ignition involve many conditions. Among them, the important conditions are gas properties, gas pressure, electrode shape, Electrode position, electrode spacing, applied voltage, applied power and frequency, etc.
Area IV and Area V are glow discharge areas:
Area IV of the atmospheric plasma surface cleaning machine is a normal glow discharge area, which mainly exists during the discharge process of the cleaning machine, while area V is an abnormal glow discharge area.


plasma surface cleaner


Between the two electrodes of the atmospheric plasma surface cleaning machine, after the voltage drops to a certain value, the current increases sharply, as if the resistance between the electrodes has increased indefinitely before point B; after point B, the resistance between the electrodes tends to zero. The phenomenon is called ignition, VB is called thermal power generation voltage, and the discharge after ignition is called self-sustained discharge. At this time, Tangsheng discharge enters the self-sustained area from the non-self-sustaining area.
