Isigaba: I-Polytetrafluoroethylene (PTFE) I-Teflon Material
I-Polytetrafluoroethylene (PTFE) iyi-fluoropolymer yokwenziwa ye-tetrafluoroethylene enezinhlelo eziningi zokusebenza ngenxa yezakhiwo zayo ezihlukile. Yatholwa ngengozi ngo-1938 ngusokhemisi ogama lakhe linguRoy Plunkett ngenkathi esebenza ekwakheni isiqandisi esisha. PTFE yaziwa kakhulu ngegama lomkhiqizo i-Teflon, okungenkampani yamakhemikhali iDuPont.
PTFE iwumsebenzi ongasabeli kakhulu futhi ozinzile ngokushisa okumelana namakhemikhali amaningi, okuhlanganisa ama-asidi nezisekelo. Ine-coefficient ephansi kakhulu yokungqubuzana, okuyenza ibe ukukhetha okuhle kakhulu ukuthi isetshenziswe ezinhlelweni lapho ukungqubuzana okuphansi kufiswa khona, njengamabheringi nama-seal. PTFE iphinde ibe isivikelo esihle kakhulu sikagesi, okuyenza ibe wusizo ezinhlelweni zikagesi.
Enye yezinhlelo zokusebenza ezaziwa kakhulu ze PTFE ikuzitsha zokupheka ezinganamathi. Izakhiwo ezinganamatheli ze PTFE kungenxa yamandla ayo aphansi, avimbela ukudla ukuthi kunamathele ebusweni be-cookware. PTFE iphinde isetshenziswe kwezinye izinhlelo zokusebenza lapho kufunwa khona izinto ezinganamatheli, njengasekuhlanganisweni kwemishini yezokwelapha kanye nasekukhiqizeni ama-gasket kanye nezimpawu.
PTFE ibuye isetshenziswe embonini ye-aerospace ngenxa yokumelana kwayo nezinga lokushisa eliphezulu kanye ne-coefficient ephansi yokungqubuzana. Isetshenziswa ekwenzeni izingxenye zezinjini zezindiza, njengezimvu zamanzi namabheringi. PTFE ibuye isetshenziswe ekwakhiweni kwamasudi asemkhathini ngenxa yekhono layo lokumelana namazinga okushisa aphakeme kanye nezindawo zayo ezinganamathele.
Ngaphezu kokusetshenziswa kwayo emigqeni engagxili kanye nezicelo ze-aerospace, PTFE ibuye isetshenziswe ekukhiqizeni eminye imikhiqizo ehlukahlukene, njengezintambo zamakhompiyutha, izingxenye zezimoto, nezindwangu zezimboni. Ibuye isetshenziselwe ukukhiqizwa kwendwangu ye-Gore-Tex, into engenamanzi futhi ephefumulayo esetshenziselwa izingubo zangaphandle nezicathulo.
Ekuphetheni, PTFE iwumsebenzi oguquguqukayo onezici ezihlukile eziyenza isebenziseke ezinhlobonhlobo zezinhlelo zokusebenza. Imvelo yayo engasasebenzi, i-coefficient ephansi yokungqubuzana, kanye nokumelana nezinga lokushisa eliphezulu kuyenza ibe ukukhetha okuhle kakhulu ukuze isetshenziswe kuma-non-stick, izingxenye ze-aerospace, nezinye izinhlelo zokusebenza zezimboni.
