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).

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.

The biocompatibility ea polymer leha e le efe e sebelisoang sesebelisoa sa bongaka ke taba e totobetseng.PTFE e ipabola sebakeng sena mme e na le nalane e telele ea ts'ebeliso ea in vivo.Li-fluoropolymer tsa boemo ba bongaka li lokela ho fihlela litlhoko tsa tlhahlobo tsa USP Class VI le ISO 10993.Ke ’nete hore ho sebetsana le bohloeki le hona ke ntlha ea bohlokoa.
