    摘要: A continuous plasma treatment process is disclosed. The process may include providing at least one plasma treatment zone having a pair of electrodes with endless dielectric belts, each belt having a first and a second side that covers one of the electrodes. The process may include producing a non-thermal plasma in a space between the belts, and transporting a web material via the belts such that there is a width of exposed belt on either side of the web material. The process may include transporting the web material such that a side of the web material not in contact with the belts is treated in two passes through the at least one plasma treatment zone, while exposed parts of the belts transporting the web material are also treated. The process may include cleaning treated parts of the belts prior to the belts re-entering the at least one plasma treatment zone.

    摘要: An apparatus and method are for disinfection and purification of a liquid, gaseous or solid phase, or a mixture thereof. The apparatus includes: a central electrode, a dielectric layer adjacent to the electrode, a first area adjacent to the dielectric layer, and is configured to introduce a first medium into the first area, a second area adjacent to the first area. The apparatus is also configured to introduce a second medium into the second area, and for creating a plasma in the first medium, while the first medium is present in the first area, by applying a voltage between the first electrode and a second electrode. An injector injects the plasma into the second area, in order to be mixed with the second medium.

    摘要: A method applies a coating (17) of a thermoplastic material on a substrate (11) made of a polymeric material, with the thermoplastic material and the polymeric material being incompatible. Firstly, the substrate and/or the powder are exposed to a plasma discharge (12) or the reactive gas stream resulting therefrom in order to obtain a plasma treated surface layer (14) introducing compatibility at the interface between substrate and coating. Secondly, laser cladding (15) the powder (16) on the substrate is conducted in order to form a coating on the substrate.
