57 Abstract AB [DE] Die Neuerung bezieht sich auf eine mechanisch stabile poröse Membran, ein Verfahren zu ihrer Herstellung und ihre Verwendung. Nachteilig am Stande der Technik bleibt, neben aufwendigen Lösungswegen und Begrenzung der Größe der Mikrosiebe, hauptsächlich entweder die mechanische Instabilität der porösen Membranen, die erst mittels eines separaten Verfahrensschrittes nachträglich durch Anbringung einer Stützstruktur beseitigt werden muss, oder die nicht exakt auf die spätere Trennaufgabe zugeschnittene Größe der Funktionsporen. Dieses Problem wird durch die in den Hauptansprüchen angegebenen Merkmale durch die gleichzeitige Erzeugung einer mechanisch stabilen porösen Schicht eigentlichen Membranherstellungsprozess selbst wenigstens einseitig auf der porösen Membran, mit Porengröße und Membranstärke entsprechend der späteren Trennaufgabe, gelöst. Vorteile der Lösung bestehen im Wegfall nachträglicher separater Anbringung einer Stützstruktur auf der porösen Membran und damit auch Wegfall der dabei immer vorhandenen Beschädigungsgefahr der porösen Membran. Dadurch wird die gesamte Prozessführung effektiver, also schneller und kostengünstiger, und die Größeneinschränkung besteht auch nicht.
[EN] The mechanically stable porous membrane (1) for the separation of particle and/or fluid drop from gases or fluids, comprises a mechanically stable porous layer (2), which is produced by a membrane manufacturing process and which consists of large pores (B), arranged along a side of the porous membrane, which is formed from a monolayer or a thin layer made of small functional pores (A) that are uniform and possess a size that corresponds to the later separation task. The functional- and large pores are interconnected with one another for allowing the passage of materials through them. The mechanically stable porous membrane (1) for the separation of particle and/or fluid drop from gases or fluids, comprises a mechanically stable porous layer (2), which is produced by a membrane manufacturing process and which consists of large pores (B), arranged along a side of the porous membrane, which is formed from a monolayer or a thin layer made of small functional pores (A) that are uniform and that possess a size that corresponds to the later separation task. The functional- and large pores are interconnected with one another for allowing the passage of materials through the pores. The thickness of the porous membrane is less than the diameter of the functional pores, which have a pore size of 500-30 nm. The co-produced mechanically stable porous layer has a layer thickness of two-thirds of the diameter of the large pores. The layer thickness on both sides of the porous membrane has same or different magnitude. In the case of one-sided arrangement of the stable porous layer, the porous membrane possesses a boundary layer roughness below the pore size of the respective functional pores. An independent claim is included for a procedure for the production of a mechanically stable porous membrane.
