等離子表麵處理和電暈處理有什麽不同

VDO3YM@64)E%8%DOMU4AJXC.png

等離子表麵處理器與電暈的效果是差不多一樣的,隻不過處理方式不一樣,電暈隻能處理很薄的東西,如塑料膜一類的東西,要求處理物體積不能大了,用於寬麵積處理。


其原理是利用高頻率高電壓在被處理的塑料表麵電暈放電(高頻交流電壓高達5000-15000V/m2),而產生低溫等離子體,(等離子表麵處理)使塑料表麵產生遊離基反應而使聚合物發生交聯.表麵變粗糙並增加其對極性溶劑的潤濕性-這些離子體由電擊和滲透進入被印體的表麵破壞其分子結構,(等離子表麵處理)進而將被處理的表麵分子氧化和極化,離子電擊侵蝕表麵,以致增加承印物表麵的附著能力。


等離子處理機用於在線式處理,配到各種生產線上處理可以處理曲麵表麵。(等離子表麵處理)對物體大小沒有局限性。兩種達到的效果是一樣的,隻不過對被處理物來說那一種更適用。

                                            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.
