PEEKndi thermoplastic yosagwira kutentha yomwe imagwira ntchito bwino ikakhudzidwa ndi kutentha kwambiri komanso malo okhala ndi mankhwala.Kuthekera kwazinthu izi kusunga mawonekedwe ake komanso kupirira kutentha mpaka madigiri 480 F kumapangitsa kukhala chinthu chamtengo wapatali chomwe chili choyenera kugwiritsidwa ntchito mosiyanasiyana kuphatikiza kusinthira zitsulo zosapanga dzimbiri m'malo ovuta.Ndi njira yopepuka yosinthira chitsulo ndi aluminiyamu ndipo imakhala yolimba kwambiri popanda mafuta.
PTFEndi crystalline polima yokhala ndi malo osungunuka pafupifupi 621° F (327° C).Kachulukidwe ndi 2.13 mpaka 2.19 gm/cc.PTFE ili ndi kukana kwapadera kwa mankhwala.Dielectric zake zonse (2.1) ndi zotayika ndizotsika komanso zokhazikika pakutentha kwakukulu komanso kusiyanasiyana.PTFE ili ndi zinthu zothandiza zamakina kuchokera ku kutentha kwa cryogenic pa 500 ° F (280 ° C) kutentha kosalekeza kwautumiki.Coefficient of friction yake ndi yotsika kuposa zinthu zina zilizonse.Lilinso ndi mlingo wochuluka wa okosijeni.
Kuyerekeza kwa PEEK ndi Polymer PTFE/FEP Property Values
Ntchito Zofunika:
* PEEK: Bearings; Mapampu; Magawo a Piston; Kutsekereza Kwachingwe.*PTFE: Cabling zothetsera; Non mafuta fani; O-mphete; Zisindikizo; Capacitors; Semiconductor kupanga; High kutentha mbali magetsi; Gaskets; Vavu zigawo.
Katundu:
*PEEK: Kukana kwamphamvu kwa abrasion; Kuyamwitsa pang'ono kwa chinyezi; Kukana kwamphamvu kwamankhwala; Kukangana kochepa; Makhalidwe abwino amavalidwe; Kutheka.*PTFE:Zabwino kwambiri dielectric katundu;Kusalimba kwa mankhwala ambiri;Kutentha kwakukulu ndi kukana mankhwala;Coeffiecient yotsika kwambiri ya kukangana;Kukaniza bwino kwa radiation;Ziro chinyezi mayamwidwe;Kupanda chidwi ndi ma frequency amphamvu;Kutheka.
