Title (EN) METHOD FOR PRODUCING A SHAPED MEMBRANE
(FR) PROCÉDÉ DE PRODUCTION D’UNE MEMBRANE FORMÉE
(DE) VERFAHREN ZUR HERSTELLUNG EINER GEFORMTEN MEMBRAN
Abstract:
(EN) The present invention relates to a method for producing a shaped membrane, comprising the following steps: a) providing a plastic film, b) heating the plastic film to a temperature T1 which is above the melting point of the plastic film, c) quenching the plastic film to a temperature T2 which is below the melting point, d) heating the plastic film to a temperature T3 which is below the melting point and above the temperature T2, e) shaping the heated plastic film.
(FR) L'invention concerne un procédé de production d’une membrane formée, comportant les étapes suivantes : a) la préparation d’un film en matière plastique ; b) le chauffage du film en matière plastique à une température T1 qui se situe au-dessus du point de fusion du film en matière plastique ; c) le refroidissement rapide du film en matière plastique à une température T2 qui se situe au-dessous du point de fusion ; d) le chauffage du film en matière plastique à une température T3 qui se situe au-dessous du point de fusion et au-dessus de la température T2 ; e) le formage du film en matière plastique chauffé.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer geformten Membran mit den Schritten a) Bereitstellen einer Kunststofffolie, b) Erwärmen der Kunststofffolie auf eine Temperatur T1, die oberhalb des Schmelz punktes der Kunststofffolie liegt, c) Abschrecken der Kunststofffolie auf eine Temperatur T2, die unterhalb des Schmelzpunktes liegt, d) Aufheizen der Kunststofffolie auf eine Temperatur T3, die unterhalb des Schmelz-punktes und oberhalb der Temperatur T2 liegt, e) Umformen der aufgeheizten Kunststofffolie.
