Mbiri ya Polytetrafluorofentlene adayamba pa Epulo 6, 1938 ku Du Pont a Labotary ya New Jersey. Pa tsiku losangalatsali, Dr. Roy J. Pluncekett, yemwe anali kugwira ntchito ndi mipweya yokhudzana ndi Freon Revierrants, adazindikira kuti Sampuli imodzi inali ndi yoyera mpaka yoyera.

Kuyesa kunawonetsa kuti izi zinali zinthu zodabwitsa kwambiri. Unali utomoni womwe unakana kwambiri mankhwala kapena zosungunulira; Pamwamba pake panali poterera kotero kuti pafupifupi palibe amene angagwiritsire ntchito; Chinyontho sichimapangitsa kuti kutupa, ndipo silinanyongetse kapena kukhala wopanda nkhawa pambuyo powonekera kwa dzuwa. Idakhala ndi malo osungunuka 327 ° C ndipo, osatinso a thermophuphustics wamba, sizimayenda pamwamba pa malo osungunuka. Izi zikutanthauza kuti njira zatsopano zosinthira zimayenera kupangidwa kuti zigwirizane ndi mawonekedwe a New Resin yatsopano - omwe duni wotchedwa Teflon.

Maluso obwereka kuchokera ku ufa ku ufa, mainjiniya akatswiri amatha kutsutsa ndi kumwanitsa ndi uchimo. Pambuyo pake, kubalalitsidwa kwa utomoni m'madzi kunapangidwa kuti ukhale wovala nsalu yamagalasi ndikupanga ma enmels. Ufa unapangidwa kuti utha kuphatikizidwa ndi mafuta ndi kutulutsa waya ndi zojambula.

Podzafika mu 1948, patadutsa zaka 10 pambuyo pa kupezeka kwa polytetrafluofentlene, du Pont anali ntchito yophunzitsira kwa makasitomala ake. Posachedwa chomera chamalonda chinali ntchito, ndipo polytetrafluofentylene PTFES PTFES adapezeka pakubala, ma resin a granolar ndi ufa wabwino.

Chifukwa Chiyani Tiyenera Kusankha NYU YA PTFY?

Ptfe kapena polytetrafluoro solylene ndi amodzi mwa zinthu zosagwirizana kwambiri ndi zomwe zilipo. Izi zimathandizira mapulani a PTF kuti zitheke mkati mwa mafakitale osiyanasiyana pomwe mitsempha yachitsulo kapena phweka imalephera. Patulani izi ndi matemberedwe abwino kwambiri (-70 ° C kwa + 260 ° C) ndipo mumatha kukhala ndi mpesa wolimba kwambiri kuposa malo ena a Harsise.

Katundu wamatsenga a PTFF amalola kusintha kwamitengo yoyenda bwino ponyamula ma vinya. Izi zimathandizanso kutikita mwapangidwe kosavuta komanso kumapangitsa kuti 'osasunthika' osasunthika, kuonetsetsa kuti kwatsala ndi malonda kungangotaya kapena kungotsukidwa.
