AusprüfungTesting
Ein Kupferlackdraht der einen Blankdrahtdurchmesser von 0,4 mm hat wird mit 8 Schichten eines handelsüblichen Polyesterimiddrahtlackes lackiert. Danach folgen 2 Schichten eines handelsüblichen Polyamidimides. Als letzte Schicht wird das erfindungsgemäße Gleitmittel aufgebracht und eingebrannt. Der Lackierofen hat eine Temperatur von 520°C.One Copper enamel wire has a bare wire diameter of 0.4 mm with 8 layers of a commercial Polyesterimiddrahtlackes painted. This is followed by 2 layers of one commercial Polyamide-imide. The last layer is the lubricant according to the invention applied and baked. The painting oven has a temperature of 520 ° C.
Der dynamische Reibungskoeffizient wird mit einem Gerät der Firma MAG, Modell MSLL20 gemessen in Anlehnung an DIN 46453.Of the dynamic friction coefficient is using a device of the company MAG, model MSLL20 measured in accordance with DIN 46453.
Die Extraktionswerte wurden mit Freon R 22 in Anlehnung an die Norm NEMA MW 1000 bestimmt. Ergebnisse: The extraction values were determined using Freon R 22 in accordance with the NEMA MW 1000 standard. Results:
Der Reibungskoeffizient der erfindungsgemäßen Formulierung hat eine Größe die den marktüblichen Produkten entsprechen.Of the Coefficient of friction of the formulation according to the invention has a size that the market-standard products correspond.
Der Gehalt an extrahierbaren Anteilen liegt mit kleiner 0,1% in einem Bereich der den Einsatz der Lackdrähte in hermetischen Motoren ermöglich.Of the Content of extractable fractions is less than 0.1% in one Field of use of the enameled wires in hermetic motors allows.
