Zinthu zakuthupi za bolodi la PTFE
Zinthu zakuthupi za bolodi la PTFE
Mkulu kutentha kukana-kutentha ntchito angafikire 250 ℃.
Low kutentha kukana-ali wabwino makina kulimba; ngakhale kutentha kutatsikira ku -196 ℃, kumatha kupitilira kukulira kwa 5%.
Kukana kwa dzimbiri-ilibe mankhwala ambiri komanso zosungunulira, ndipo imatha kupirira zidulo zamphamvu ndi zamchere, madzi ndi zosungunulira zosiyanasiyana.
Kukaniza nyengo-kumakhala ndi ukalamba wabwino kwambiri pakati pa mapulasitiki.
Konderetsedwe kokwanira-ndiye koyefishienti yotsika kwambiri yamikangano pakati pazida zolimba.
Osamatira-ndikumangika kwakung’ono kwambiri pakati pazinthu zolimba ndipo sikumamatira kuzinthu zilizonse. Kapangidwe kazitsulo zamagetsi ndi kocheperako, 1/5 yokha ya polyethylene, yomwe ndi gawo lofunikira la perfluorocarbon padziko. Kuphatikiza apo, chifukwa fluorine kaboni unyolo wamkati mwa ma molekyulu ndi otsika kwambiri, PTFE siyokakamira.
Osakhala poizoni-Ndiwopanda thupi ndipo samakumana ndi zovuta ngati zotengera zamagazi zopangira ndi ziwalo zomwe zimayikidwa m’thupi kwa nthawi yayitali.
Zamagetsi zamagetsi Polytetrafluoroethylene imakhala ndi ma dielectric otsika nthawi zonse komanso kutaya kwa ma dielectric pafupipafupi, ndipo imakhala ndi magetsi owonongeka, voliyumu yotsutsana ndi kukana kwa arc.
Kuteteza kwa ma radiation Polytetrafluoroethylene kumakhala kosakanikirana bwino ndi radiation (104 rad), ndipo kumawononga pambuyo pokhala ndi cheza champhamvu kwambiri, ndipo magetsi ndi makina amtundu wa polima amachepetsedwa kwambiri. Kugwiritsa ntchito Polytetrafluoroethylene kumatha kupangidwa ndi kupsinjika kapena extrusion processing; itha kupangidwanso kuti kupezeka kwamadzi kwa zokutira, kusunsa kapena kupanga ulusi. Polytetrafluoroethylene chimagwiritsidwa ntchito ngati kutentha ndi otsika kutentha zosagwira, dzimbiri zosagwira zipangizo, chimateteza zipangizo, odana ndi kukakamira zokutira, etc. mu mphamvu ya nyukiliya, Azamlengalenga, zamagetsi, magetsi, mankhwala, makina, zida, mamita, zomangamanga, nsalu, chakudya ndi zina mafakitale.
Kukalamba kwakumapeto kwa mpweya: kukana kwa ma radiation ndi kuchepa kochepa: kuwonekera kwakanthawi mlengalenga, mawonekedwe ake ndi magwiridwe ake sanasinthe.
Zosayaka: Ndondomeko ya malire a oxygen ili pansipa 90.
Acid ndi alkali kukana: osasungunuka mwamphamvu zidulo, zamchere zamchere ndi zosungunulira organic.
Makutidwe ndi okosijeni kukana: kugonjetsedwa ndi dzimbiri ndi michere yolimba.
Acidity: Kusalowerera ndale.
Mawotchi a PTFE ndi ofewa. Ali ndi mphamvu yotsika kwambiri.
Polytetrafluoroethylene (F4, PTFE) ili ndi magwiridwe antchito abwino kwambiri: kutentha kwaposachedwa kutentha -kugwiritsa ntchito madigiri 200 ~ 260, kutsika kwakanthawi kotsika-kofewabe pamadigiri -100; dzimbiri kukana-kukana kwa aqua regia ndi zosungunulira zonse zachilengedwe; Kukaniza nyengo – moyo wokalamba kwambiri m’mapulasitiki; kondomu yayikulu-ndi koyefishienti yaying’ono kwambiri yamipikisano (0.04) m’mapulasitiki; osakakamira-ndikumangika kocheperako pazinthu zolimba popanda zomatira zilizonse; non-poizoni-ndi zokhudza thupi inertness; Mphamvu zamagetsi, ndi zinthu zabwino kwambiri za C-class zoteteza.
