Reines PTFE hat eine herausragende Chemikalienbest\u00e4ndigkeit und die geringste Reibung aller festen Polymere, dazu ein Problem mit Druckkriechen, das es f\u00fcr alles unter Dauerlast zu einer schlechten Wahl macht. F\u00fcllstoffe existieren, um das zu beheben, und jeder gibt daf\u00fcr etwas ab.<\/p>\n\n
Glasfasern, meist mit 15 oder 25 Prozent, liefern die gr\u00f6\u00dfte Verbesserung von Kriechfestigkeit und Druckfestigkeit f\u00fcrs Geld und lassen die Chemikalienbest\u00e4ndigkeit nahezu unver\u00e4ndert. Es ist der Standard f\u00fcr Dichtungen, Lager und Pumpenbauteile. Der Nachteil ist, dass er den Reibungskoeffizienten erh\u00f6ht und gegen\u00fcber einer Gegenfl\u00e4che aus Metall abrasiv wirkt.<\/p>\n\n
Kohlenstoff und Graphit liefern eine bessere Verschlei\u00dfleistung und W\u00e4rmeleitf\u00e4higkeit, und anders als Glas zerkratzen sie die Welle nicht. Kohlenstoffgef\u00fclltes PTFE ist die Wahl f\u00fcr trocken laufende Lager. Bronze liefert mit Abstand die h\u00f6chste W\u00e4rmeleitf\u00e4higkeit und Tragf\u00e4higkeit, weshalb es in Hydraulikdichtungen und Kolbenringen vorkommt \u2014 ist aber f\u00fcr chemische Anwendungen nicht geeignet, weil die Bronze korrodiert. Wenn Sie uns das Medium, die Last und die Drehzahl nennen, k\u00f6nnen wir den F\u00fcllstoff meist in einer Antwort benennen.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
