Surface treatment with barrier discharge

摘要

The invention relates to the treatment, in particular the cleaning, of surfaces, in particular foil and metal surfaces. They are mostly covered with an oil film or greased immediately after their production. Greases and oils must, however, be removed before subsequent processing of the surfaces or of the foils, in order to permit acceptable coating or adhesive bonding. It is intended for this to be carried out quickly and with low energy expenditure, and it is achieved by the invention in that a dielectrically hindered discharge (12, 2, 3, 13a) acts on the surface of the foil strip (10), for example. By the action of highly energetic charged particles and by the action of photons from the UV spectral range, the oil or grease film is removed after just a short time to the extent that subsequent processing (coating or adhesive bonding) is possible, without the occurrence of increased energy expenditure or incidence of damage to the surface. <IMAGE>
