Ipleyiti ye-UHMWPE kunye nepleyiti ye-PTFE okwangoku zezona zisetyenziswa kakhulu iiplastiki ezingezizo ezentsimbi kwimarike.Iimpawu eziqhelekileyo zombini iipleyiti zeplastiki zobunjineli ezinokuxhathisa ukubola, ukuzithambisa kunye ne-coefficient ephantsi ye-friction.Iimpawu ezahlukeneyo zibonisa ukuba ipleyiti ye-UHMWPE ixhaphake kakhulu kunepleyiti ye-PTFE, kodwa uxhathiso oluphezulu lobushushu alulunganga njengepleyiti yePTFE.Okulandelayo, ndiza kushwankathela umahluko omkhulu phakathi kwezi zimbini ngokweenkcukacha:
UHMWPE ipleyiti kunyeipleyiti ye-PTFEngoku zezona zisetyenziswa kakhulu iiplastiki ezingezizo ezentsimbi kwimarike.Iimpawu eziqhelekileyo zombini iipleyiti zeplastiki zobunjineli ezinokuxhathisa ukubola, ukuzithambisa kunye ne-coefficient ephantsi ye-friction.Iimpawu ezahlukeneyo zibonisa ukuba ipleyiti ye-UHMWPE ixhaphake kakhulu kunepleyiti ye-PTFE, kodwa uxhathiso oluphezulu lobushushu alulunganga njengepleyiti yePTFE.Okulandelayo, ndiza kushwankathela umahluko omkhulu phakathi kwezi zimbini ngokweenkcukacha:
1. Ukumelana nokunxiba: Ipleyiti ye-UHMWPE inokumelana nokugqwesa okugqwesileyo, ukuphakama kobunzima bemolekyuli, ngcono ukuxhathisa kokunxiba kwezinto.2. I-friction coefficient: kuba i-UHMWPE ineempawu zokuzithambisa.Ngoko ke, inokusebenza kwimodi ye-sliding okanye ejikelezayo ngaphandle kweoli yokuthambisa, engcono kunentsimbi kunye nobhedu kwiimeko zokuthambisa.
3. Izinga lokufunxa kwamanzi: Ipleyiti ye-UHMWPE inezinga eliphantsi kakhulu lokufunxa amanzi.Ayifunxa kakhulu amanzi, ayidumbi emanzini, kwaye incinci kakhulu kunenayiloni.4. Ukumelana nemichiza: I-plate ye-UHMWPE inozinzo oluphezulu lweekhemikhali, kwaye inokumelana nesenzo semithombo yeendaba ezonakalisayo (i-asidi, i-alkali, ityuwa) kunye ne-solvents eziphilayo ezifana ne-asidi, i-alkali, ityuwa, njl. ngaphakathi kwinqanaba elithile lobushushu kunye noxinzelelo.
5. Ayinatyhefu: Ipleyiti ye-UHMWPE ayinavumba, ayinatyhefu, ayinavumba, ayinamhlwa, kwaye inokuhamba ngebhayisikile yefiziyoloji kunye nokuguquguquka komzimba.I-US Food and Drug Administration (FDA) kunye neSebe lezoLimo lase-United States (i-USDA) livumela ukuba lisetyenziswe Isetyenziswe kwiimeko apho idibene nokutya kunye namayeza, ngoko ifanelekile kumashishini afuna ucoceko oluphezulu. iimeko ezifana nokutya namayeza.
