Method of cleaning the surface of a material coated with an organic substrate 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.
