Mefuta ea PTFE tube
Ho itšetlehile ka kopo, PTFE tube e arotsoe ka mekhahlelo e meraro e pharaletseng - e 'ngoe le e' ngoe e hlalosoa ka bophara ba tube le botenya ba lerako (sheba Lethathamo la 2).
Esita le ka har'a lihlopha, PTFE tube e itšetlehile ka mefuta e fapaneng, e 'ngoe le e' ngoe e lumella ho sebelisoa ho fapaneng (sheba Lethathamo la 3):
PTFE tube 'marakeng oa lisebelisoa tsa bongaka
Ka kakaretso, tube e nyane ea spaghetti e sebelisoa lits'ebetsong tsa bongaka.Tšebeliso ea PTFE sebakeng sena e itšetlehile ka thepa e 'meli ea bohlokoa: lubricity le biocompatibility.Li-fluoropolymers li bonts'a lubricity e ntle haholo ha li bapisoa le li-plastiki tse ling.PTFE ke polymer ea lubricious ka ho fetisisa e fumanehang, e nang le coefficient of friction ea 0.1, e lateloa ke fluorinated ethylene propylene (FEP), e nang le 0.2.Li-polymer tsena tse peli li emela boholo ba li-tubes tsohle tsa fluoropolymer tse sebelisoang lisebelisoa tsa bongaka.
