Category: Polytetrafluoroethylene (PTFE) Zinthu za Teflon
Polytetrafluoroethylene (PTFE) ndi fluoropolymer yopanga ya tetrafluoroethylene yomwe ili ndi ntchito zambiri chifukwa cha mawonekedwe ake apadera. Zinapezeka mwangozi mu 1938 ndi katswiri wa zamankhwala dzina lake Roy Plunkett pamene anali kugwira ntchito yopanga firiji yatsopano. PTFE amadziwika kwambiri ndi dzina la Teflon, lomwe ndi la kampani yamankhwala DuPont.
PTFE ndi chinthu chosasunthika komanso chosasunthika komanso chokhazikika chomwe chimalimbana ndi mankhwala ambiri, kuphatikiza ma acid ndi maziko. Ili ndi coefficient yotsika kwambiri ya kukangana, kupangitsa kuti ikhale chisankho chabwino kwambiri kuti igwiritsidwe ntchito ngati mikangano yocheperako ikufunika, monga ma fani ndi zosindikizira. PTFE ilinso insulator yabwino kwambiri yamagetsi, yomwe imapangitsa kuti ikhale yothandiza pamagetsi.
Chimodzi mwazodziwika bwino ntchito za PTFE ili muzophika zosamata. The sanali ndodo katundu wa PTFE ndi chifukwa cha mphamvu yake yotsika pamwamba, yomwe imalepheretsa chakudya kumamatira pamwamba pa chophika. PTFE amagwiritsidwanso ntchito m'zinthu zina zomwe zimafunidwa zopanda ndodo, monga zokutira zipangizo zamankhwala ndi kupanga ma gaskets ndi zosindikizira.
PTFE imagwiritsidwanso ntchito m'makampani opanga ndege chifukwa cha kukana kwake kutentha komanso kutsika kwamphamvu kwamphamvu. Amagwiritsidwa ntchito popanga zida za injini za ndege, monga zisindikizo ndi ma bere. PTFE imagwiritsidwanso ntchito popanga ma suti am'mlengalenga chifukwa chotha kupirira kutentha kwambiri komanso zinthu zake zopanda ndodo.
Kuphatikiza pakugwiritsa ntchito zokutira zopanda ndodo komanso kugwiritsa ntchito ndege, PTFE amagwiritsidwanso ntchito popanga zinthu zina zosiyanasiyana, monga zingwe zamakompyuta, zida zamagalimoto, ndi zokutira zamakampani. Amagwiritsidwanso ntchito popanga nsalu za Gore-Tex, zomwe zimakhala zopanda madzi komanso zopumira zomwe zimagwiritsidwa ntchito popanga zovala zakunja ndi nsapato.
Pomaliza, PTFE ndi zinthu zosunthika zomwe zimakhala ndi zinthu zapadera zomwe zimapangitsa kuti zikhale zothandiza pamagwiritsidwe osiyanasiyana. Chikhalidwe chake chosasunthika, kugunda kocheperako, komanso kukana kutentha kwambiri kumapangitsa kuti ikhale chisankho chabwino kwambiri chogwiritsa ntchito zokutira zopanda ndodo, zida zamlengalenga, ndi ntchito zina zamafakitale.
