Pali mitundu iwiri yaPTFE mbale: kuumba ndi skiving / kutembenuka.The akamaumba mbale amapangidwa polytetrafluoroethylene utomoni ndi akamaumba pa firiji, ndiyeno sintered ndi utakhazikika.Chophimbacho chimapangidwa ndi PTFE utomoni mwa kukanikiza, sintering, ndi peeling.
Pali mitundu iwiri yaPTFE mbale: kuumba ndi skiving / kutembenuka.The akamaumba mbale amapangidwa polytetrafluoroethylene utomoni ndi akamaumba pa firiji, ndiyeno sintered ndi utakhazikika.Chophimbacho chimapangidwa ndi PTFE utomoni mwa kukanikiza, sintering, ndi peeling.
PTFE mbale imakhala yabwino kwambiri kukana ma abrasion pakati pa mapulasitiki onse aumisiri ndipo ndiyopatsa chidwi kwambiri.Kulemera kwa mamolekyu kumapangitsa kuti zinthuzo zisavale, ngakhale kuposa zida zambiri zachitsulo (monga chitsulo cha carbon, chitsulo chosapanga dzimbiri, mkuwa, ndi zina zotero).Mwachitsanzo, mapaipi a UHMW-pe amakhala ndi moyo wautumiki wa nthawi 4-6 kuposa mipope yachitsulo pansi pa kuwonongeka kwamphamvu ndi kuvala kwakukulu, ndipo mphamvu yotumizira ikuwonjezeka ndi 20%.Imawonetsa bwino kwambiri "kupulumutsa mphamvu, kuteteza chilengedwe, chuma, komanso kuchita bwino kwambiri".
Ubwino wa mbale ya PTFE ndi chiyani?
Kukana kutentha kwambiri- Kutentha kwa ntchito kumatha kufika 250 ℃.
Kukana kutentha kwapansi- Ali ndi kulimba kwamakina abwino;ngakhale kutentha kutsika mpaka -196 ℃, kumatha kukhala ndi kutalika kwa 5%.
Kukana dzimbiri- Imakhala ndi mankhwala ambiri ndi zosungunulira, ndipo imatha kupirira ma acid amphamvu ndi alkalis, madzi ndi zosungunulira zosiyanasiyana.
Kukana kwanyengo- Ali ndi moyo wokalamba wabwino kwambiri pakati pa mapulasitiki.
Kupaka mafuta kwambiri- Chotsitsa chotsika kwambiri cha kukangana pakati pa zida zolimba.
Kusamamatira- Ndiko kukanikizana kochepa kwambiri pakati pa zida zolimba ndipo sikumamatira kuzinthu zilizonse.Kuthamanga kwamphamvu kwa zinthu zamakina kumakhala kochepa kwambiri, 1/5 yokha ya polyethylene, yomwe ndi yofunika kwambiri pa perfluorocarbon pamwamba.Kuphatikiza apo, chifukwa mphamvu ya fluorine-carbon chain intermolecular ndi yotsika kwambiri, PTFE ndiyosakhazikika.
Zopanda poizoni- Ndi inertness physiological, kuyika kwa nthawi yayitali kwa mitsempha yamagazi ndi ziwalo zopanga thupi popanda zoyipa.
Mitundu yogwiritsira ntchito mbale ya PTFE ili motere:
1. Pogwiritsa ntchito mawonekedwe a friction coefficient, imagwiritsidwa ntchito pobowola mafuta akunyanja derrick slide veneer, dock slide veneer, river dam gate gate slide veneer, bridge telescopic support slide veneer, zida zamakina osiyanasiyana, makina otopetsa, chopukusira, chowongolera chowongolera chowongolera. , ndi zina.
2. Pogwiritsa ntchito zinthu zake zopanda ndodo, zimagwiritsidwa ntchito m'makampani a shuga, mafakitale a zovala, chakudya, lamba wophika fodya, kusindikiza, ndi kupanga utoto wa anti-sticking anti-corrosion ❖ ❖ kuyanika wosanjikiza wa ma roller osiyanasiyana, etc.
3. Kugwiritsiridwa ntchito kwa ma dielectric motors kumakhala ndi ntchito yabwino kwambiri ndipo kumagwiritsidwa ntchito m'malo opangira magetsi otentha, maselo a electrolytic, mphete zosindikizira, maulendo osindikizira mu zipangizo zamagetsi ndi mafakitale apakompyuta, zigawo zamkuwa zamkuwa, zida zosiyanasiyana zodula komanso zida zapadera.
4. Kugwiritsa ntchito kukhazikika kwake kwamankhwala, kumatha kugwiritsidwa ntchito makamaka ngati ma gaskets, linings, ma valve discs, ndi ma diaphragms a mavavu akuluakulu m'mafakitale amafuta, mankhwala, ndi mankhwala, komanso zomangira zotengera zosiyanasiyana, matanki osungira. , ndi reaction towers, mbale yogawa, ndi zina.
Kugwiritsa ntchito mbale yosinthidwa ya PTFE
Zosinthidwa PTFE mbalendi zinthu zomwe amakonda pazitsulo zosagwira dzimbiri, ndiye madera ogwiritsira ntchito mbale ya PTFE yosinthidwa ndi chiyani?
Monga zinthu zosindikizira, mbale zosinthidwa za PTFE zimagwiritsidwa ntchito kwambiri pamakina, petrochemical, mayendedwe, nsalu, ndi mafakitale omanga.Malinga ndi osankhidwa mpweya permeability wa mbale PTFE pambuyo mankhwala, angagwiritsidwe ntchito ngati zinthu kulekana kuti kusankha kumadutsa mpweya kapena madzi, makamaka zosefera zamadzimadzi zikuwononga.M'zaka zaposachedwa, mbale yosinthidwa ya PTFE yakhala ikugwiritsidwa ntchito ngati chiwalo chopanga, ndipo idzagwiritsidwa ntchito m'madera osiyanasiyana m'tsogolomu, yomwe ili ndi chiyembekezo chabwino cha chitukuko.
