Amateka ya POLYTETRAFLUOROETHYLENE yatangiye ku ya 6 Mata 1938 muri Laboratwari ya Jackson ya Du Pont muri New Jersey. Kuri uwo munsi wamahirwe, Dr. Roy J. Plunkett, wakoranaga na gaze zijyanye na firigo ya FREON, yavumbuye ko icyitegererezo kimwe cyahise gikonjesha ubwacyo kugeza cyera, kishashara.

Kwipimisha byerekanaga ko iki kintu gikomeye cyari ibikoresho bidasanzwe. Nibisigarira byarwanyaga hafi ya buri miti izwi cyangwa ibishishwa; ubuso bwacyo bwari bwanyerera ku buryo nta kintu na kimwe cyakomeraho; ubuhehere ntibwigeze butera kubyimba, kandi ntibwigeze bugabanuka cyangwa ngo bucike nyuma yigihe kirekire izuba ryinshi. Ryari rifite ubushyuhe bwa 327 ° C kandi, bitandukanye na thermoplastique isanzwe, ntirishobora gutembera hejuru yuwo gushonga. Ibi bivuze ko tekinike nshya yo gutunganya yagombaga gutezwa imbere kugirango ihuze ibiranga resin nshya - Du Pont yise TEFLON.

Inguzanyo zo gutekesha ifu ya metallurgie, abajenjeri ba Du Pont bashoboye kwikuramo no gucumura POLYTETRAFLUOROETHYLENE ibisigazwa mubice bishobora gutunganywa kugirango bibe byifuzwa. Nyuma, gukwirakwiza ibisigazwa byamazi byatejwe imbere kugirango bitwikire umwenda w ibirahure no gukora emam. Hakozwe ifu yashoboraga kuvangwa n'amavuta hanyuma ikoherezwa ku nsinga ya koti no gukora tubing.

Kugeza 1948, nyuma yimyaka 10 ivumbuwe rya POLYTETRAFLUOROETHYLENE, Du Pont yigishaga tekinoroji yo gutunganya abakiriya bayo. Bidatinze, uruganda rwubucuruzi rwatangiye gukora, maze ibisigazwa bya POLYTETRAFLUOROETHYLENE PTFE biboneka mu gutatanya, ibisigazwa bya granula na poro nziza.

Kuki uhitamo PTFE Hose?

PTFE cyangwa Polytetrafluoroethylene nikimwe mubikoresho birwanya imiti biboneka. Ibi bifasha ama shitingi ya PTFE gutsinda muburyo butandukanye bwinganda aho ibyuma gakondo gakondo cyangwa reberi bishobora kunanirwa. Huza ibi hamwe nubushyuhe buhebuje (-70 ° C kugeza + 260 ° C) hanyuma urangize na hose iramba cyane ishobora kwihanganira bimwe mubidukikije bikaze.

Imiterere itavanze ya PTFE ituma igipimo cyogutemba neza mugihe cyo gutwara ibikoresho bifatika. Ibi kandi bigira uruhare muburyo bworoshye-busukuye kandi mubyukuri birema umurongo 'utari inkoni', ukemeza ko ibicuruzwa bisigaye bishobora kwikuramo cyangwa gukaraba gusa.
