Polychlorotrifluoroethylene (PCTFE kapena PTFCE) Katundu & Ntchito

Polychlorotrifluoroethylene (PCTFE kapena PTFCE) ndi thermoplastic chlorofluoropolymer yokhala ndi formula ya molekyulu (CF2CClF)n, pomwe ndi chiwerengero cha mayunitsi a monomer mu molekyulu ya polima.Ndizofanana ndi polytetrafluoroethene (PTFE), kupatula kuti ndi homopolymerof the monomer chlorotrifluoroethylene (CTFE) m'malo mwa tetrafluoroethene.Ili ndi mphamvu yotsika kwambiri yotumizira nthunzi wamadzi kuposa pulasitiki iliyonse.

Katundu CTFE ili ndi mphamvu zolimba kwambiri komanso mawonekedwe abwino otentha.Siziyaka moto ndipo kukana kutentha kumafika pa 175 ° C.Ili ndi coefficient yotsika ya kukulitsa kutentha.Kutentha kwa magalasi (Tg) ndi pafupifupi 45 ° C.PCTFE ili ndi imodzi mwazoletsa kwambiri oxygen index (LOI).Ili ndi kukana kwamankhwala abwino.Imawonetsanso zinthu monga mayamwidwe a chinyontho zero komanso osanyowetsa.Sichitenga kuwala kowoneka.Ikayikidwa ndi ma radiation amphamvu kwambiri, imakumana, monga PTFE, kuwonongeka.Itha kugwiritsidwa ntchito ngati filimu yowonekera.Kukhalapo kwa atomu ya chlorine, yokhala ndi utali wa atomiki wokulirapo kuposa wa fluorine, kumalepheretsa kulongedza kwapafupi kotheka mu PTFE.Izi zimapangitsa kukhala ndi malo otsika kwambiri osungunuka pakati pa ma fluoropolymers, kuzungulira 210-215 ° C.PCTFE imagonjetsedwa ndi kuukiridwa ndi mankhwala ambiri ndi oxidizing agents, katundu wowonetsedwa chifukwa cha kukhalapo kwa fluorine wambiri.Komabe, imafufuma pang'ono mumagulu a halocarbon, ethers, esters ndi zosungunulira zonunkhira.PCTFE imagonjetsedwa ndi okosijeni chifukwa ilibe maatomu a haidrojeni.PCTFE ikuwonetsa mphindi yokhazikika ya dipole chifukwa cha asymmetry ya molekyulu ya gawo lake lobwereza.Mphindi ya dipole ili ndi perpendicular kwa carbon-chain axis.Mapulogalamu CTFE imapeza zambiri zomwe zimagwiritsidwa ntchito chifukwa cha zinthu ziwiri zazikulu: kuthamangitsidwa kwa madzi ndi kukhazikika kwa mankhwala.Mafilimu a PCTFE amagwiritsidwa ntchito ngati chotetezera ku chinyezi.Izi zikuphatikizapo:• chotchinga chinyezi pamapaketi a matuza amankhwala,• chotchinga cha nthunzi wamadzi poteteza zokutira za phosphor mu nyali za electroluminescent (mankhwala a phosphor amamva chinyezi),• chitetezo chazitsulo zowonetsera zamadzimadzi (LCD), zomwe zimakhudzidwa ndi chinyezi.Chifukwa cha kukhazikika kwake kwa mankhwala, zimakhala ngati chotchinga choteteza ku mankhwala.Amagwiritsidwa ntchito ngati zokutira komanso zopangira liner popangira mankhwala.PCTFE amagwiritsidwanso ntchito kwa laminating ma polima ena monga PVC, polypropylene, PETG, APET etc. Amagwiritsidwanso ntchito mandala magalasi, machubu, mavavu, liners thanki mankhwala, O-mphete, zisindikizo ndi gaskets.PCTFE imagwiritsidwa ntchito kuteteza zida zamagetsi zamagetsi chifukwa cha kukana kwake kwamagetsi komanso kukana madzi.Ntchito zina ndi monga mabwalo osinthika osindikizidwa komanso kutsekereza mawaya ndi zingwe.Ma PCTFE olemera kwambiri a PCTFE waxes, mafuta ndi mafuta amapeza ntchito ngati zosindikizira zopanda mafuta ndi mafuta.Amagwiritsidwanso ntchito ngati madzi a gyroscope flotation ndi mapulasitiki opangira thermoplastics.
