POM-C und POM-H sind beide Acetal, beide als Stange und Platte auf Lager und beide werden oft einfach als Acetal angeboten. Sie sind nicht bei jeder Aufgabe austauschbar.<\/p>\n\n
Das Homopolymer ist etwas h\u00e4rter, steifer und etwa zehn Prozent fester, mit besserer Kriechfestigkeit unter Dauerlast. Es hat au\u00dferdem einen sch\u00e4rferen kristallinen Schmelzpunkt, wodurch es bei stranggepressten Stangen mit gro\u00dfem Durchmesser anf\u00e4lliger f\u00fcr Porosit\u00e4t entlang der Mittellinie ist. Wenn Sie eine 150-mm-Stange auf eine 140-mm-Buchse mit aufgebohrtem Kern abdrehen, wird die Porosit\u00e4t zu Ihrer Ausschussquote.<\/p>\n\n
Das Copolymer hat ein breiteres Verarbeitungsfenster, deutlich geringere Porosit\u00e4t in dicken Querschnitten und eine bessere Best\u00e4ndigkeit gegen hei\u00dfes Wasser und schwache Laugen. Bei allem \u00fcber 80 mm Durchmesser oder allem, was nahe der Mittellinie bearbeitet wird, setzen wir standardm\u00e4\u00dfig auf POM-C und haben selten einen Grund zu wechseln. POM-H verdient seinen Platz bei kleinen, hoch belasteten, eng tolerierten Teilen, bei denen sich die zus\u00e4tzliche Steifigkeit bezahlt macht.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
