Abstract
Beschrieben wird ein Verfahren zur Oberflaechenbehandlung eines Werkstueckes aus einem elastomeren Werkstoff mit einem, auf die Oberflaeche des Werkstueckes einwirkenden Energiestrom. Die Erfindung zeichnet sich dadurch aus, dass der Energiestrom auf das Werkstueck einwirkt, waehrend das Werkstueck gedehnt wird.
DE 10000132 A UPAB: 20011018 NOVELTY - The surface of an elastomer material is treated with an energy stream, which acts on the surface while the material is stretched. DETAILED DESCRIPTION - The workpiece is a flat membrane (1), and the energy stream is directed at least at one of the two sides. The energy is in the form of an ion or electromagnetic radiation, aligned at the surface of the stretched workpiece. The energy is generated together with a plasma which forms the ions. The workpiece material is clamped to cover a hollow zone on one side, where an overpressure stretches it. An INDEPENDENT CLAIM is included for an elastomer membrane workpiece, where the macro mols. have a high cross linking level and especially in the zones near the surface. USE - The membrane is for use in pressure stores or hydraulic systems. ADVANTAGE - The process gives a targeted increase in the cross linking of macro mols. within the elastomer material, at least in the layers close to the surface. It gives a targeted reduction in the permeation of gases through the elastomer membrane.
