UHMW-PE wirkt wie ein Kompromissmaterial. Es ist weich, hat einen niedrigen Schmelzpunkt und seine Zugfestigkeit ist unspektakul\u00e4r. In Verschlei\u00dfanwendungen schl\u00e4gt es Materialien, die f\u00fcnfmal so viel kosten.<\/p>\n\n
Der Grund ist seine Abriebfestigkeit, die die h\u00f6chste aller Thermoplaste ist und bei Gleitverschlei\u00df h\u00f6her liegt als bei vielen St\u00e4hlen. Kommt ein sehr niedriger Reibungskoeffizient hinzu \u2014 niedriger als bei Polyamid oder Acetal \u2014, erh\u00e4lt man ein Material, das abrasives Sch\u00fcttgut gleiten l\u00e4sst, statt dass es sich eingr\u00e4bt. Bei F\u00f6rderbandauskleidungen, Rutschenauskleidungen, Kettenf\u00fchrungen und Sternr\u00e4dern \u00fcbertrifft es Metall unter nassen oder klebrigen Bedingungen an Lebensdauer, weil es nicht korrodiert und Sch\u00fcttgut nicht daran haftet.<\/p>\n\n
Zwei Konstruktionshinweise. Es kriecht, setzen Sie es daher nicht als Strukturbauteil unter Dauerlast ein \u2014 st\u00fctzen Sie es durchgehend. Und es l\u00e4sst sich sehr schwer verkleben, planen Sie daher eine mechanische Befestigung mit Senkkopfschrauben. Unter diesen beiden Randbedingungen ist es meist die richtige Antwort.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
