Gulu ndi magwiridwe antchito a PTFE board

Polytetrafluoroethylene board (yomwe imadziwikanso kuti tetrafluoroethylene board, Teflon board, Teflon board) imagawika m’magulu awiri: kuumba ndikusintha. Wopangidwa ndi kuzirala. The PTFE kutembenukira bolodi unapangidwa PTFE utomoni ndi kukanikiza, sintering ndi khungu. Zogulitsa zake ndizogwiritsidwa ntchito zosiyanasiyana komanso zabwino kwambiri: kutentha kwambiri (-192 ℃ -260 ℃), kukana dzimbiri (asidi wamphamvu, alkali wamphamvu, aqua regia, ndi zina), kulimbana ndi nyengo, kutentha kwambiri, kutentha kwambiri kondomu, osamatira, Osakhala poizoni ndi mawonekedwe ena abwino.

Pepala la Polytetrafluoroethylene ndi polima lomwe limapangidwa ndi ma polymerization a tetrafluoroethylene. Kapangidwe kake kamakhala kosavuta monga – [- CF2-CF2-] n-, yomwe imakhala ndi bata labwino kwambiri komanso yosagwira dzimbiri (polytetrafluoroethylene Yotchedwa PTFE kapena F4, ndi imodzi mwazinthu zosagwira dzimbiri padziko lapansi masiku ano. “Pulasitiki King “ndi dzina lodziwika bwino la polytetrafluoroethylene. Ndi mtundu wa pulasitiki wokhala ndi dzimbiri wabwino. Sukhudzidwa ndi zidulo, alkalis, Kutupa kwa mchere ndi oxidant sikungathandize ngakhale ndi aqua regia, chifukwa chake amatchedwa Plastic King. Kupatula osungunuka ndi sodium ndi madzi fluorine, imagonjetsedwa ndi mankhwala ena onse. Amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zosindikiza zomwe zimafuna kulimbana ndi zidulo, alkalis ndi zosungunulira zachilengedwe. Kutentha kwabwino kwambiri (kumatha kugwira ntchito mpaka 250 + mpaka -180 ℃ kwa nthawi yayitali). , Amaganiziridwa kuti amakhala ndi zotsatira za khansa.

Kutentha: -20 ～ 250 ℃ (-4 ～ + 482 ° F), kulola kuzirala mwachangu ndi kutenthetsa, kapena kugwiranso ntchito kozizira ndi kutentha.

Anzanu -0.1, 6.4Mpa (kuthamanga kwathunthu koipa kwa 64kgf / cm2) (Fullvacuumto64kgf / cm2)

Kupanga kwake kwathetsa mavuto ambiri mdziko langa la mankhwala, mafuta, mankhwala ndi zina. Zisindikizo za Polytetrafluoroethylene, gaskets, gaskets. Zidindo za Polytetrafluoroethylene ndi ma gaskets amapangidwa ndi kuyimitsidwa kwa politetrafluoroethylene utomoni. Poyerekeza ndi mapulasitiki ena, PTFE ili ndi mawonekedwe a kukana kwamankhwala, ndipo yakhala ikugwiritsidwa ntchito kwambiri ngati zinthu zosindikiza ndikudzaza zinthu. Zowonongeka zake zonse pamadigiri pafupifupi 500 Celsius ndi tetrafluoroethylene, hexafluoropropylene ndi octafluorocyclobutane. Zoterezi zimawononga mpweya wokhala ndi zakumwa zotentha kwambiri kutentha.

Kugwiritsa ntchito pepala la PTFE

Mitundu yosiyanasiyana yazogulitsa za PTFE yatenga gawo lofunika kwambiri pachuma chadziko monga mafakitale, makina, zamagetsi, zida zamagetsi, zamagulu azankhondo, malo osungira zinthu zachilengedwe, kuteteza zachilengedwe ndi milatho. Tetrafluoroethylene board ndiyabwino kutentha kwa -180 ℃ ~ + 250 ℃. Amagwiritsidwa ntchito ngati zida zamagetsi zotchingira ndi zolumikizira polumikizana ndi media zowononga, zothandizira zosunthira, zisindikizo zanjanji ndi zida zopaka mafuta. Mipando yolemera yama kabati imagwiritsa ntchito m’makampani opepuka. , Amagwiritsidwa ntchito kwambiri popanga mankhwala, mankhwala, zotengera zautoto, akasinja osungira, nsanja zoyankhira, mapaipi akulu opangira zinthu; ndege, magulu ankhondo ndi magulu ena olemera; makina, zomangamanga, zotchinga milatho yamagalimoto, maupangiri; kusindikiza ndi kudaya, mafakitale opepuka, nsalu Zida zotsutsana ndi zomatira pamsikawu, ndi zina zambiri.
