PTFE bolodi (lotchedwanso PTFE bolodi, Teflon bolodi, Teflon bolodi) lagawidwa mitundu iwiri: akamaumba ndi kutembenuka.Zogulitsa zake zimagwiritsidwa ntchito kwambiri ndipo zimakhala ndi zinthu zapamwamba kwambiri: kukana kutentha kwambiri komanso kutsika (-192 ° C-260 ° C), kukana dzimbiri (asidi wamphamvu, alkali wamphamvu, aqua regia, etc.), kukana nyengo, kutchinjiriza kwakukulu, mafuta okwera, osaphatikiza, Osakhala ndi poizoni ndi makhalidwe ena abwino kwambiri.Polytetrafluoroethylene (Chidule cha Chingerezi ndi Teflon kapena [PTFE, F4]), yomwe imadziwika kuti "Pulasitiki King", dzina lamalonda laku China "Teflon", "Teflon" (teflon), "Teflon", "Teflon", "Teflon" ndi zina zotero.
Ndi mkulu maselo pawiri polymerized ndi tetrafluoroethylene, ndi dongosolo lake chosavuta ndi -[-CF2-CF2-] n-, amene ali kwambiri kukhazikika kwa mankhwala ndi dzimbiri kukana (polytetrafluoroethylene amatchedwa PTFE kapena F4, ndi chimodzi mwa dzimbiri kwambiri. -Zinthu zosagwira padziko lapansi masiku ano, "Plastic King" imadziwika kuti polytetrafluoroethylene, ndi pulasitiki yokhala ndi kukana kwambiri kwa dzimbiri.Simakhudzidwa ndi zidulo zodziwika, alkali, salt, oxidants Corrosion, ngakhale aqua regia alibe chochita. Imalimbana ndi mankhwala ena onse kupatula chitsulo chosungunula cha sodium ndi fluorine yamadzimadzi, osamata, kusungunula kwamagetsi komanso kukana kukalamba bwino, kukana kutentha kwambiri (kumatha kugwira ntchito kwa nthawi yayitali pakutentha kwanthawi yayitali). + 250 ° C mpaka -180 ° C) PTFE yokha si poizoni kwa anthu, koma imagwiritsidwa ntchito popanga Imodzi mwa zipangizo za perfluorooctanoate ammonium (PFOA) imatengedwa kuti ndi khansa yotheka.
Kutentha -20～250°C (-4°+482°F), kulola kuzirala kwadzidzidzi ndi kutentha kwadzidzidzi, kapena kugwira ntchito kwina kozizira ndi kotentha.
Pressure -0.1 ~ 6.4Mpa (Vacuum yonse mpaka 64kgf/cm2) (Vacuum yonse mpaka 64kgf/cm2)
Kupanga kwake kwathetsa mavuto ambiri pamakampani opanga mankhwala, mafuta amafuta ndi mankhwala m'dziko lathu.PTFE zisindikizo, gaskets, gaskets, PTFE zisindikizo, ndi gaskets anapangidwa kuyimitsidwa polymerized PTFE utomoni akamaumba.Poyerekeza ndi mapulasitiki ena, PTFE ili ndi mawonekedwe oletsa dzimbiri, ndipo yakhala ikugwiritsidwa ntchito kwambiri ngati zida zosindikizira komanso zodzaza.
Zinthu zake zonse zowola ndi kutentha pafupifupi madigiri 500 Celsius zimaphatikizapo tetrafluoroethylene, hexafluoropropylene ndi octafluorocyclobutane, zomwe zidzawola mpweya wokhala ndi fluorine wowononga kwambiri pakutentha kwambiri.
