Abstract:
1. An installation for carrying out a process for cleaning the surface of a material coated with an organic substance, the process comprises introducing said material into a treatment chamber, having a pressure of between 10 mbar and 1 bar therein, which is supplied with a gas stream containing at least 90% oxygen by volume and generating a plasma by passing an electric discharge between the surface of said material and a dielectric-covered electrode, breaking down said organic substance through the action of the free radicals O. thus produced, where the material is in the form of a running strip and said introducing and generating operations are carried out continuously using installations placed in succession along the path of the running strip, the installation comprising: at least one module comprising a treatment chamber, means for setting the pressure inside said chamber to a value between 10 mbar and 1 bar, means for making said strip run through said chamber, a series of dielectric-covered electrodes placed so as to face that surface of said strip to be treated, where the electrodes are connected to a single sinusoidal high-voltage generator, a gas supplying unit that supplies said chamber with gas and a gas extraction unit that extracts, from said chamber, the gases resulting from the decomposition of the organic substance coating the strip, and UV emission lamps placed in an alternating order directly adjacent with said electrodes, wherein the UV emission lamps are configured to irradiate the strip at substantially the same time.
