Three Effect Modes about Atmospheric Pressure Plasma

Atmospheric pressure plasma has three effect modes to choose from. One is to use an argon/oxygen combination, which is mainly used for non-metallic materials and requires high processing effects. The second is to use an argon/nitrogen combination, which mainly faces the metal area that cannot be treated for the product to be treated. This problem can be controlled by replacing the nitrogen in this scheme due to the strong oxidation of oxygen. The third is that only argon is used, and surface modification can be achieved only by using argon gas, but the effect is relatively low. This situation is more special and is a solution used by a small number of industrial customers for limited and uniform surface modification

The atmospheric plasma is also a low temperature plasma that does not damage the surface of the material. No arc, no vacuum chamber, no harmful gas suction system, long-term use will not cause physical damage to the operator.

Atmospheric glow plasma technology. RF RF is used as the excitation energy and the operating frequency is 13.56 MHz. Argon (Ar) is used as a generating gas, and oxygen or nitrogen is used as a reaction gas.

Advantages of plasma cleaning machine: There are two main methods, namely cavity type and atmospheric pressure type. Both plasma technologies are direct plasma. The characteristics of the chamber plasma are that a closed cavity is required, and the electrode is built in the vacuum chamber. First, a vacuum pump is used to suck out the air in the cavity to form a vacuum-like environment, and then the plasma is formed in the entire cavity and directly opposed thereto. The material is surface treated. This type of cavity plasma treatment is superior to atmospheric plasma. The subsequent operation cost is higher, mainly because the vacuum pump has a large power consumption for continuous operation. In addition, the equipment requires a lot of time in the vacuum process, and the limitations are obvious for the industrial fields that use automated production lines and require processing efficiency
