Method for producing separating nozzle elements

摘要

Method for producing a separating nozzle element including a separating body and terminal plates, for the separation of a gaseous or vaporous mixture, wherein the separating body comprises separating structures which penetrate the separating body and define separating chambers and gas conduits, and the terminal plates are provided with channels for the intake and discharge of gas streams. A mold layer is produced which contains negative outlines of the separating structures. Thereafter, the negative outlines of the mold layer are filled with a structure material which is compatible with the gaseous or vaporous mixture to be separated to form the separating structures. The mold layer containing the negative outlines of the separating structure is produced by shaping the mold layer from a reusable tool provided with the positive outlines of the separating structures.
