METHOD OF CLEANING THE SURFACE OF A MATERIAL COATED WITH AN ORGANIC SUBSTANCE AND A GENERATOR AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a method for the continuous cleaning of the surface of a material (2) which is coated with an organic substance. The inventive method comprises the following steps, consisting in: introducing the material (2) into a treatment area which is supplied with a gas stream containing oxygen; earthing the material (2); and generating a plasma by imposing an electric field between the surface of the material (2) and at least one dielectric-covered electrode (3), said electric field being pulsed and comprising a succession of positive and negative voltage pulses in relation to the material (2). Moreover, the maximum voltage of the positive pulses U+ is greater than the arc striking voltage Ua and the maximum absolute value voltage of the negative pulses U- is less than the striking voltage Ua. The invention also relates to a generator and a device which are used to carry out said method.
