Ipuleti le-UHMWPE nepuleti le-PTFE njengamanje amapulasitiki amabili angewona awensimbi asetshenziswa kakhulu emakethe.Izici ezivamile zazo zombili amapuleti epulasitiki obunjiniyela anokumelana nokugqwala, ukuzigcoba kanye ne-coefficient ephansi yokungqubuzana.Izici ezihlukene zibonisa ukuthi ipuleti le-UHMWPE aligugi kakhulu kunepuleti le-PTFE, kodwa ukumelana nezinga lokushisa okuphezulu akukuhle njengepuleti le-PTFE.Okulandelayo, ngizofingqa umehluko omkhulu phakathi kwalokhu okubili ngokuningiliziwe:
UHMWPE plate kanyeIpuleti le-PTFEnjengamanje amapulasitiki amabili asetshenziswa kakhulu angewona awensimbi emakethe.Izici ezivamile zazo zombili amapuleti epulasitiki obunjiniyela anokumelana nokugqwala, ukuzigcoba kanye ne-coefficient ephansi yokungqubuzana.Izici ezihlukene zibonisa ukuthi ipuleti le-UHMWPE aligugi kakhulu kunepuleti le-PTFE, kodwa ukumelana nezinga lokushisa okuphezulu akukuhle njengepuleti le-PTFE.Okulandelayo, ngizofingqa umehluko omkhulu phakathi kwalokhu okubili ngokuningiliziwe:
1. Ukumelana nokugqoka: Ipuleti le-UHMWPE linokumelana okuhle kakhulu nokugqokwa, ukuphakama kwesisindo samangqamuzana, kuba ngcono ukumelana nokugqokwa kwezinto.2. I-Friction coefficient: ngoba i-UHMWPE inezinto zokuzithambisa.Ngakho-ke, ingasebenza kumodi yokushelela noma ejikelezayo ngaphandle kwamafutha okugcoba, okungcono kunensimbi nethusi ezimweni zokugcoba.
3. Izinga lokumuncwa kwamanzi: Ipuleti le-UHMWPE linenani eliphansi kakhulu lokumunca amanzi.Ayiwamumbi kakhulu amanzi, ayivuvukali emanzini, futhi incane kakhulu kunenayiloni.4. Ukumelana namakhemikhali: Ipuleti le-UHMWPE linokuqina okuphezulu kwamakhemikhali, futhi lingakwazi ukumelana nesenzo semithombo yezindaba eyonakalisayo ehlukahlukene (i-asidi, i-alkali, usawoti) kanye nezincibilikisi eziphilayo ezifana ne-asidi, i-alkali, usawoti, njll ngaphakathi kwebanga elithile lokushisa kanye nokuhlushwa.
5. Ayinabo ubuthi: Ipuleti le-UHMWPE alinaphunga, alinabuthi, alinaphunga, aligqwali, futhi linokuhamba ngokuphila kwamabhayisikili nokuvumelana nezimo.I-US Food and Drug Administration (FDA) kanye noMnyango Wezolimo wase-United States (i-USDA) iyayivumela ukuthi isetshenziswe Isetshenziswa ngezikhathi lapho ixhumene nokudla nemithi, ngakho ifanele izimboni ezidinga inhlanzeko ephezulu. izimo ezifana nokudla nemithi.
