Polychlorotrifluoroethylene (PCTFE kapa PTFCE) Thepa le Lisebelisoa

Polychlorotrifluoroethylene (PCTFE kapa PTFCE) ke thermoplastic chlorofluoropolymer e nang le foromo ea molek'hule (CF2CClF)n, moo e leng palo ea li-unit tsa monomer molek'hule ea polymer.E tšoana le polytetrafluoroethene (PTFE), ntle le hore ke homopolymerof the monomer chlorotrifluoroethylene (CTFE) sebakeng sa tetrafluoroethene.E na le sekhahla se tlase sa phetiso ea mouoane oa metsi ho feta polasetiki efe kapa efe.

Thepa CTFE e na le matla a phahameng a tsitsipano le litšobotsi tse ntle tsa mocheso.Ha e chese 'me e mamella mocheso ho fihla ho 175 ° C.E na le coefficient e tlase ea katoloso ea mocheso.Thempereichara ea phetoho ea khalase (Tg) e ka ba 45 °C.PCTFE e na le index ea oksijene e fokolang e phahameng ka ho fetisisa (LOI).E na le khanyetso e ntle ea lik'hemik'hale.E boetse e bonts'a thepa e kang ho monya mongobo oa zero le ho se kolobise.Ha e monye khanya e bonahalang.Ha e hlasetsoe ke mahlaseli a matla a phahameng, e ea, joalo ka PTFE, ho senyeha.E ka sebelisoa e le filimi e hlakileng.Boteng ba athomo ea chlorine, e nang le radius e kholo ea athomo ho feta ea fluorine, e sitisa ho paka haufi ho khoneha ho PTFE.Sena se fella ka ho ba le sebaka se batlang se le tlase se qhibilihang har'a li-fluoropolymers, ho pota 210-215 °C.PCTFE e hanyetsana le tlhaselo ea lik'hemik'hale tse ngata le li-oxidizing agents, thepa e bontšitsoeng ka lebaka la ho ba teng ha fluorine e ngata.Leha ho le joalo, e kokomoha hanyane ka har'a metsoako ea halocarbon, li-ether, li-ester le li-solvents tse nkhang hamonate.PCTFE e hanana le oxidation hobane ha e na liathomo tsa haedrojene.PCTFE e bonts'a motsotso o sa feleng oa dipole ka lebaka la asymmetry ea molek'hule ea yuniti ea eona e pheta-phetoang.Motsotso ona oa dipole o shebane le axis ea carbon-chain.Lisebelisoa CTFE e fumana boholo ba ts'ebeliso ea eona ka lebaka la thepa e 'meli e meholo: ho lahla metsi le botsitso ba lik'hemik'hale.Lifilimi tsa PCTFE li sebelisoa e le lera le sireletsang khahlanong le mongobo.Tsena li kenyelletsa:• mokoallo oa mongobo ka har'a sephutheloana sa blister ea meriana,• thibelo ea mouoane oa metsi bakeng sa ho sireletsa liphahlo tsa phosphor ka mabone a electroluminescent (likhemikhale tsa phosphor li utloa mongobo),• tšireletso ea liphanele tsa li-crystal display (LCD) tse nang le bothata ba mongobo.Ka lebaka la botsitso ba lik'hemik'hale, e sebetsa e le thibelo e sireletsang lik'hemik'hale.E sebelisoa e le seaparo sa ho roala le se entsoeng esale pele bakeng sa lik'hemik'hale.PCTFE e boetse e sebelisetsoa ho laminating li-polymers tse ling tse kang PVC, polypropylene, PETG, APET joalo-joalo E boetse e sebelisoa ka likhalase tsa mahlo tse bonaletsang, li-tubes, li-valve, li-liner tanka tsa lik'hemik'hale, li-O-rings, li-seals le li-gaskets.PCTFE e sebelisoa ho sireletsa likarolo tsa elektronike tse hlokolosi ka lebaka la matla a eona a ho hanyetsa motlakase le ho thibela metsi.Litšebeliso tse ling li kenyelletsa lipotoloho tse hatisitsoeng tse feto-fetohang le ho koala lithapo le likhoele.Li-wax tsa PCTFE tse boima bo tlase ba limolek'hule, oli le mafura li fumana ts'ebeliso ea tsona e le li-sealants tse inert le mafura.Li boetse li sebelisoa e le metsi a flotation a gyroscope le li-plasticizers bakeng sa thermoplastics.
