I-Polytetrafluoroethylene (PTFE)yafunyanwa ngusokhemisti uGqr Roy J. Plunkett eDuPont's Jackson Laboratory eNew Jersey ngo-1938. Xa wayezama ukwenza irefrigerant entsha yeCFC, i-polytetrafluoroethylene eyenziwe ngepolymer kwisitya sogcino olunoxinzelelo oluphezulu (intsimbi eseludongeni lwangaphakathi lwenqanawa yaba yirefrigerant entsha. i-catalyst ye-polymerization reaction). Inkampani yaseDuPont yafumana ipatent yayo ngo 1941 kwaye yabhalisa uphawu lwayo lwentengiso phantsi kwegama elithi "TEFLON" ngo 1944. Kamva, iDuPont yaqalisa ishishini layo eTeflon & reg; Ukongeza kwi-PTFE resin, siye saqulunqa uluhlu lweemveliso, kuquka iTeflon; I-AF (i-amorphous fluoropolymer), iTeflon; I-FEP (i-fluorinated ethylene propylene resin), iTeflon; I-FFR (i-fluoropolymer foam resin), iTeflon; I-NXT (i-fluoropolymer resin), iTeflon; PFA (perfluoroalkoxy resin) njalo njalo.

Ibhanti yokuhambisa iTeflon

Iimveliso zalo mathiriyeli zibizwa ngokuba "ziingubo ezingeyontonga"; Luhlobo lwemathiriyeli yokwenziwa yepolymer esebenzisa ifluorine ukubuyisela zonke iiathom zehydrogen kwipolyethylene. Esi sixhobo sineempawu zokuxhathisa i-asidi, ukuxhathisa kwe-alkali kunye neentlobo ezahlukeneyo ze-solvents eziphilayo, kwaye ziphantse zinganyibiliki kuzo zonke izinyibilikisi. Ngelo xesha, i-polytetrafluoroethylene ineempawu zokumelana nokushisa okuphezulu, kwaye i-coefficient yayo ye-friction iphantsi kakhulu, ngoko ingasetyenziselwa njenge-lubrication, kwaye ibe yinto efanelekileyo yokugqoka ngaphandle kwe-oyile ye-oyile kunye nomgangatho wangaphakathi wombhobho wamanzi.

I-Teflon ingasetyenziswa kwibhanti yokuhambisa: ibhanti lokuhambisa iTeflon, ibhanti lokuhambisa leTeflon, ibhanti lokuhambisa ulusu olubandayo, ibhanti lokuhambisa umbhobho, ilaphu leTeflon, ibhanti lelaphu le-PTFE, ibhanti lekhaphethi, ilaphu lemethi yocango, ibhanti lokuhambisa ukutya, njl. Kwakhona uyisebenzise kwiteyiphu: iteyiphu encamathelayo yeTeflon, iTeflon yeglasi yokuncamathela ifayibha yeglasi, iTeflon iteyiphu yokumelana nobushushu obuphezulu, iteyiphu yokuncamathela, ilaphu lokuzincamathela, njl.
