Mtengo wa PTFE

PTFE gaskets ndi katundu kwambiri zokwawa kukana, ozizira otaya kukana, kopitilira muyeso-otsika kutentha kukana, palibe kuipitsa, ndi unsembe mosavuta ndi disassembly. Pansi pa mphamvu yaying’ono isanakhazikike, imatha kupirira kupanikizika kwakukulu kwamkati ngakhale m’malo osinthasintha. Ndiwoyenera kwambiri pamagalasi owoneka bwino kapena osasunthika komanso osasunthika komanso nthawi yosindikiza yosintha kutentha. Titha kusankha Gore, Klinger, Garlock, Sealon ndi mapepala ena owonjezera a PTFE kuti makasitomala apange ma gaskets ofunikira kwa makasitomala.

zopindulitsa

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.

Kukana kwanyengo – kumakhala ndi moyo wokalamba wabwino kwambiri mu mapulasitiki.

Kupaka mafuta kwambiri – ndiko kutsika kwapakati kwa mikangano muzinthu zolimba.

Kusamamatira-kutanthawuza kuti kugwedezeka kwapamtunda muzinthu zolimba ndizochepa ndipo sizimamatira ku chinthu chilichonse. Zochita zake zamakina zimakhala ndi kagawo kakang’ono kwambiri kakangano, komwe ndi 1/5 yokha ya polyethylene. Ichi ndi chinthu chofunika kwambiri cha perfluorocarbon pamwamba. Kuphatikiza apo, chifukwa mphamvu ya fluorine-carbon chain intermolecular ndi yotsika kwambiri, PTFE ndiyosakhazikika.

Non-poizoni ndi zoipa-ndi zokhudza thupi inertia, monga yokumba magazi chotengera ndi chiwalo anaika mu thupi kwa nthawi yaitali popanda chokhwima zochita.

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.

Kukana kwa radiation Polytetrafluoroethylene imakhala ndi kukana koyipa kwa radiation (104 rad), ndipo imatsitsa pambuyo powonetsedwa ndi cheza champhamvu kwambiri, ndipo mphamvu zamagetsi ndi makina a polima zimachepetsedwa kwambiri. Ntchito Polytetrafluoroethylene akhoza kupangidwa ndi psinjika kapena extrusion processing; Angathenso kupangidwa kukhala madzi amwazikana kuti azipaka, kuviika kapena kupanga ulusi. PTFE chimagwiritsidwa ntchito monga mkulu ndi otsika kutentha kugonjetsedwa, dzimbiri zosagwira zipangizo, insulating zipangizo, odana ndi ndodo zokutira, etc. mu mphamvu 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) ali ndi mndandanda wa ntchito zabwino kwambiri: kutentha kwapamwamba kukana-nthawi yayitali yogwiritsira ntchito kutentha kwa madigiri 200 ~ 260, kukana kutentha kochepa-kumakhalabe kofewa pa -100 madigiri; kukana dzimbiri-kukana kwa aqua regia ndi zosungunulira zonse za organic; Kukana kwa nyengo-kukalamba moyo mu mapulasitiki; mafuta okoma kwambiri – ndi kagawo kakang’ono ka mikangano (0.04) mu mapulasitiki; kusamata – ndi kugwedezeka pang’ono pamwamba pa zinthu zolimba popanda kumatira kwa zinthu zilizonse; zopanda poizoni-ndi thupi inertness; kwambiri magetsi katundu , Ndi abwino C-level insulating zakuthupi.
