Kugwiritsa ntchito ndi zabwino za PTFE board

Mitundu yonse yazinthu za PTFE zakhala zikugwira ntchito yofunika kwambiri pazachuma cha dziko monga makampani opanga mankhwala, makina, zamagetsi, zida zamagetsi, makampani ankhondo, zakuthambo, kuteteza chilengedwe ndi milatho.
Tetrafluoroethylene board ndi oyenera kutentha kwa -180 ℃ ~ + 250 ℃.Amagwiritsidwa ntchito makamaka ngati zida zotchinjiriza zamagetsi ndi zomangira zolumikizirana ndi media zowononga, zowongolera, zisindikizo za njanji ndi zida zopaka mafuta.Amagwiritsidwa ntchito m'makampani opepuka ndi mipando yolemera ya kabati., Amagwiritsidwa ntchito kwambiri mu mankhwala, mankhwala, zotengera mafakitale utoto, akasinja yosungirako, reaction tower ketulo, odana ndi dzimbiri akalowa zipangizo mapaipi lalikulu;ndege, asilikali ndi mafakitale ena olemera;makina, zomangamanga, zoyenda mlatho, njanji zowongolera;kusindikiza ndi utoto, makampani kuwala, nsalu Makampani odana zomatira zipangizo, etc.
Ubwino wakuthupi
Kukana kutentha kwakukulu - kutentha kwa ntchito kumatha kufika 250 ° C.
Kukana kutentha kwapansi - kumakhala ndi kulimba kwa makina abwino;ngakhale kutentha kutsika mpaka -196 ° C, kumatha kukhala ndi kutalika kwa 5%.
Kulimbana ndi dzimbiri - kusagwirizana ndi mankhwala ambiri ndi zosungunulira, kugonjetsedwa ndi asidi amphamvu ndi alkalis, madzi ndi zosungunulira zosiyanasiyana zamoyo.
Kulimbana ndi nyengo - ali ndi moyo wokalamba wabwino kwambiri pakati pa mapulasitiki.
Kupaka mafuta kwambiri - kutsika kocheperako kwa kukangana pakati pa zida zolimba.
Kusamatira - ndizovuta kwambiri padziko lapansi pakati pa zinthu zolimba, sizimamatira kuzinthu zilizonse, ndipo makina ake amakhala ndi kagawo kakang'ono kwambiri, komwe ndi 1/5 yokha ya polyethylene, yomwe ndi gawo lofunikira la perfluorocarbon. pamwamba.Ndipo chifukwa cha mphamvu yochepa kwambiri ya intermolecular ya fluorine-carbon unyolo, PTFE si yomata.
Non-poizoni - ndi physiologically inert ndipo alibe zotsatira zoipa pamene aikidwa m'thupi monga chotengera magazi yokumba ndi chiwalo kwa nthawi yaitali.
Mphamvu zamagetsi PTFE ili ndi kutayika kwa dielectric mocheperako komanso kutayika kwa dielectric pafupipafupi, komanso voteji yosweka kwambiri, resistivity volume and arc resistance.
Kukana kwa radiation Kulimbana ndi ma radiation a polytetrafluoroethylene ndi osauka (104 rads), ndipo kumachepetsedwa ndi cheza champhamvu kwambiri, ndipo mphamvu zamagetsi ndi makina a polima zimachepetsedwa kwambiri.Ntchito PTFE akhoza kukonzedwa ndi psinjika kapena extrusion;Itha kupangidwanso kuti ikhale yobalalika yamadzi yopaka, kulowetsedwa kapena kupanga ulusi.PTFE chimagwiritsidwa ntchito monga mkulu ndi otsika kutentha kugonjetsedwa, dzimbiri zosagwira zipangizo, insulating zipangizo, odana ndi ndodo zokutira, etc. mu mphamvu atomiki, Azamlengalenga, zamagetsi, magetsi, mankhwala, makina, zida, mamita, zomangamanga, nsalu, chakudya ndi zina. mafakitale.
Kukana kukalamba kwa Atmospheric: kukana kwa radiation ndi kutsika kochepa: kuwonetseredwa kwanthawi yayitali mumlengalenga, pamwamba ndi magwiridwe antchito sizisintha.
Kusayaka: Mlozera wochepera wa oxygen uli pansi pa 90.
Acid ndi kukana kwa alkali: osasungunuka mu asidi wamphamvu, alkali wamphamvu ndi zosungunulira organic.
Kukana kwa okosijeni: Imatha kukana dzimbiri zamafuta amphamvu.
Acidity ndi alkalinity: ndale.
The makina zimatha PTFE ndi zofewa.Lili ndi mphamvu zochepa kwambiri.
Polytetrafluoroethylene (F4, PTFE) ili ndi machitidwe abwino kwambiri: kukana kutentha kwakukulu - kutentha kwa nthawi yayitali 200 ~ 260 madigiri, kukana kutentha kwapansi - kumakhalabe kofewa pa -100 madigiri;kukana dzimbiri - kukana kwa aqua regia ndi zosungunulira zonse za organic;Kukana kwanyengo-moyo wabwino kwambiri wokalamba pakati pa mapulasitiki;mafuta ochulukirapo - kagawo kakang'ono kwambiri kakangano (0.04) pakati pa mapulasitiki;zosamangira—kukanika kochepa kwambiri kwa pamwamba pa zinthu zolimba popanda kumamatira ku chinthu chilichonse;zopanda poizoni-physiologically inert;Zamagetsi zabwino kwambiri, ndi zida zotsekera za Class C.
