Abstract

Die Erfindung betrifft die Anwendung des Verfahrens, Werkstoffe aus Kunststoff durch nachträgliche Aktivierung ihrer Oberflächen mittels Fluorierung oder Plasma-Behandlung in ihren Benetzungseigenschaften zu verbessern. Das Verfahren soll eingesetzt werden bei Kunststoffteilen von Geschirrspülmaschinen oder Waschmaschinen, die mit der Spül- oder Reinigungsflüssigkeit direkt beaufschlagt sind. Nach diesem Verfahren werden vollständig aus einem polymeren Werkstoff, wie Polypropylen, Polyethylen, deren Copolymerisate, Polyamid oder aus einem Regenerat dieser Kunststoffe gefertigte oder mit diesem Kunststoff überzogene und in den Spülwasserkreislauf einbezogene Bauteile behandelt. Durch diese Behandlung wird ohne zusätzliche konstruktive Maßnahmen eine wesentliche Verbesserung des Abtropfverhaltens an den Spülgutträgern, wie Besteckschubladen, Geschirrkörben usw. erreicht und eine durch lipophile Lebensmittelfarbstoffe bewirkte Verfärbung der Bauteile kann nicht mehr auftreten.The invention relates to the application of the method, plastic materials by subsequent Activation of their surfaces by means of fluorination or plasma treatment in their To improve wetting properties. The process is to be used for plastic parts of dishwashers or washing machines with the washing or cleaning liquid are acted upon directly. According to this procedure, be made entirely of a polymer Material such as polypropylene, polyethylene, their copolymers, polyamide or a regenerate of these plastics manufactured or coated with this plastic and in components included in the rinse water circuit. This treatment is without additional constructive measures to significantly improve draining behavior reached the wash ware carriers, such as cutlery drawers, crockery baskets etc. and one by lipophilic Coloring of the components caused by food coloring can no longer occur.
