(DE) VERFAHREN UND VORRICHTUNG ZUM REINIGEN EINER POLYMERSCHMELZE
Abstract:
(EN) The invention relates to a method and a device for cleaning a polymer melt, which allow volatile foreign substances and solid foreign substances to be removed from said polymer melt, characterised by a filter element (4) and a vacuum of a vacuum chamber (2), the polymer melt being fed through the filter element into the vacuum of the vacuum chamber (2), said filter element (4) binding the solid foreign substances and the vacuum chamber (2) taking up the volatile foreign substances.
(FR) L'invention concerne un procédé et un dispositif pour nettoyer une masse fondue de polymère, au moyen desquels des impuretés volatiles et solides peuvent être éliminées de la masse fondue de polymère. L'invention est caractérisée par un élément filtrant (4) et un vide d'une chambre à vide (2), la masse fondue de polymère pouvant être amenée dans le vide de la chambre à vide (2) à travers l’élément filtrant, ledit élément filtrant (4) se liant aux impuretés solides et la chambre à vide (2) recevant les impuretés volatiles.
(DE) Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Reinigen einer Polymerschmelze, mit welcher flüchtige Fremdstoffe und feste Fremdstoffe aus der Polymerschmelze entfernbar sind, gekennzeichnet durch ein Filterelement (4) und ein Vakuum einer Vakuumkammer (2), wobei die Polymerschmelze durch das Filterelement in das Vakuum der Vakuumkammer (2) führbar ist, wobei das Filterelement (4) die festen Fremdstoffe bindet und wobei die Vakuumkammer (2) die flüchtigen Fremdstoffe aufnimmt.
