Mbiri ya POLYTETRAFLUOROETHYLENE idayamba pa Epulo 6, 1938 ku Du Pont's Jackson Laboratory ku New Jersey. Patsiku lamwayi limenelo, Dr. Roy J. Plunkett, yemwe ankagwira ntchito ndi mpweya wokhudzana ndi mafiriji a FREON, adapeza kuti chitsanzo chimodzi chinapangidwa ndi polymeris zokha kuti chikhale choyera, cholimba.

Kuyesedwa kunawonetsa kuti cholimba ichi chinali chinthu chodabwitsa kwambiri. Unali utomoni womwe umalimbana ndi mankhwala kapena zosungunulira zilizonse zodziwika; pamwamba pake panali poterera kwambiri mwakuti palibe chilichonse chomwe chingamamatirepo; chinyontho sichinapangitse kutupa, ndipo sichinanyoze kapena kuphulika pambuyo poyang'ana ndi dzuwa kwa nthawi yaitali. Zinali ndi malo osungunuka a 327 ° C ndipo, mosiyana ndi thermoplastics wamba, sizikanayenda pamwamba pa malo osungunukawo. Izi zikutanthauza kuti njira zatsopano zopangira zida ziyenera kupangidwa kuti zigwirizane ndi mawonekedwe a utomoni watsopano - womwe Du Pont adautcha TEFLON.

Njira zobwereka kuchokera ku zitsulo za ufa, akatswiri a Du Pont adatha kufinya ndi sinter POLYTETRAFLUOROETHYLENE resin mu midadada yomwe imatha kupangidwa kuti ipange mawonekedwe aliwonse omwe akufuna. Pambuyo pake, utomoni womwaza m'madzi unapangidwa kuti uvale nsalu zamagalasi ndikupanga enamel. Ufa unapangidwa womwe ukhoza kusakanikirana ndi mafuta odzola ndi kutulutsa kuti uyake waya ndi kupanga machubu.

Pofika m'chaka cha 1948, patatha zaka 10 kuchokera pamene POLYTETRAFLUOROETHYLENE anatulukira, Du Pont anali kuphunzitsa ukadaulo waukadaulo kwa makasitomala ake. Posakhalitsa chomera chamalonda chinayamba kugwira ntchito, ndipo POLYTETRAFLUOROETHYLENE PTFE resins inayamba kupezeka mu dispersions, granular resins ndi ufa wabwino.

Chifukwa chiyani kusankha PTFE Hose?

PTFE kapena Polytetrafluoroethylene ndi chimodzi mwazinthu zolimbana ndi mankhwala zomwe zilipo. Izi zimathandiza PTFE mapaipi kuchita bwino m'mafakitale osiyanasiyana kumene miyambo zitsulo kapena mphira mapaipi akhoza kulephera. Gwirizanitsani izi ndi kutentha kwabwino kwambiri (-70 ° C mpaka +260 ° C) ndipo pamapeto pake mumakhala ndi payipi yolimba kwambiri yomwe imatha kupirira malo ena ovuta kwambiri.

The frictionless katundu wa PTFE kulola bwino otaya mitengo ponyamula viscous zipangizo. Izi zimathandizanso kuti mamangidwe ake akhale osavuta kuyeretsa ndipo amapanga cholumikizira chopanda ndodo, kuwonetsetsa kuti chotsalacho chingathe kukhetsa madzi kapena kungochapidwa.
