VERFAHREN ZUM REINIGEN EINER MATERIALOBERFLÄCHE BESCHICHTET MIT EINER ORGANISCHEN SUBSTANZ, GENERATOR UND EINRICHTUNG ZUR DURCHFÜHRUNG DES VERFAHRENS

摘要

Continuous cleaning of the surface of a material (2) coated with an organic substance consists of introducing the material into a treatment zone fed with an oxygen gas flow and generating a plasma by imposing an electric field between the surface of the material and at least one electrode (3) coated with a dielectric. The electric field is pulsed and incorporates a succession of impulses of positive and negative voltage with respect to the material. The maximum voltage of the positive impulses (U+) is greater than the arc striking voltage (Ua) and the maximum voltage of the negative pulses (U-) has an absolute value lower than the arc striking voltage. Independent claims are also included for: (a) a generator able to be used to put the cleaning operation into service; (b) a device for putting this cleaning operation into service. The dielectric used to coat the electrodes may be alumina or stumatite.
