PEEK vs UHMW Machining

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.

Polyethylene yapamwamba kwambiri yamamolekyulu (UHMWPE, UHMW) ndi kagawo kakang'ono ka thermoplastic polyethylene.Imadziwikanso kuti high-modulus polyethylene, (HMPE), kapena high-performance polyethylene (HPPE), ili ndi maunyolo aatali kwambiri, okhala ndi molekyulu ya molekyulu nthawi zambiri pakati pa 3.5 ndi 7.5 miliyoni.Unyolo wautali umathandizira kusamutsa katundu bwino kwambiri ku msana wa polima polimbitsa kulumikizana kwa ma intermolecular.Izi zimapangitsa kuti pakhale chinthu cholimba kwambiri, chokhala ndi mphamvu zapamwamba kwambiri kuposa thermoplastic iliyonse yopangidwa pano.

Kuyerekeza kwa PEEK ndi UHMW Property Values

Ntchito Zofunika

PEEK :Zimbalangondo; Mapampu; Zigawo za Pistoni; Kuyimitsa Chingwe.

UHMW:Nyenyezi; Njanji Zowongolera; Masamba; Valani mbale; Zonyamulira; Mabampa; Unyolo; Malangizo; Zingwe; Zovala; Sprockets.

Zinthu Zakuthupi

PEEK:Kukana kwakukulu kwa abrasion; Kutsika kwa chinyezi; Kukana kwamphamvu kwamankhwala; Coefficient yotsika ya kukangana; Makhalidwe abwino ovala; Kutheka.

UHMW:Mphamvu yamphamvu kwambiri;Kutheka;Kugunda kocheperako;Kudzipaka mafuta;Kusamva mankhwala;Mayamwidwe a Zero;Kukana kwambiri kwa abrasion.
