What is the difference between plasma surface treatment and corona treatment
The effect of plasma surface processor and corona is almost the same, but the treatment method is not the same. Corona can only deal with very thin things, such as plastic film, which requires that the volume of the treated material should not be large and used for wide area treatment.
The principle is to use high-frequency and high-voltage corona discharge (high-frequency AC voltage as high as 5000-15000v / m2) on the treated plastic surface to produce low-temperature plasma (plasma surface treatment) to produce free radical reaction on the plastic surface and make the polymer cross-linked. The surface roughens and increases its wettability to polar solvents - these ionomers enter the printed body by electric shock and penetration The surface damage its molecular structure, (plasma surface treatment) will be treated surface molecules oxidation and polarization, ion electric shock erosion surface, so as to increase the substrate surface adhesion.
Plasma processor is used for on-line treatment. It can be applied to various production lines to treat curved surface. There is no limit to the size of the object. For the two, the effect is the same.
