What are the colors of different gases in the plasma cleaning machine:
The arc starting device of the plasma cleaning machine enables the atoms, ions or molecules with active energy excited state to emit light further down, thus forming the color of the plasma. Because the energy levels in each gas have different energy conversion, each process gas exhibits different luminous properties, resulting in different color properties. Typical gas colors commonly used in plasma cleaning are as follows:
CF4: Blue
SF6: Light blue
SiF4: Light blue
SiCl4: Light blue
Cl2: Light green
CCl4: Light green
H2: Pink
O2: Light yellow
N2: Red to yellow
Br2: Red
He: Red to purple
Ne: Brick red
Ar: Dark red
The glow color of the plasma cleaning machine can be used not only to identify which process gas is, but also to qualitatively evaluate whether the process gas contains no pollutants.
