Udidi: Polytetrafluoroethylene (PTFE) Izinto zeTeflon
Polytetrafluoroethylene (PTFE) yi-synthetic fluoropolymer ye-tetrafluoroethylene enezicelo ezininzi ngenxa yeempawu zayo ezizodwa. Yafunyanwa ngengozi ngo-1938 ngusokhemisti ogama linguRoy Plunkett ngelixa wayesebenza ekuphuhliseni ifriji entsha. PTFE yaziwa kakhulu ngegama lebrendi iTeflon, ephethwe yinkampani yemichiza iDuPont.
PTFE yimathiriyeli engasebenziyo kakhulu kwaye izinzile ngokwe thermally ukumelana neekhemikhali ezininzi, kubandakanya iiasidi kunye neziseko. Inomlinganiso ophantsi kakhulu wokukhuhlana, nto leyo eyenza ukuba ibe lolona khetho lubalaseleyo lokusetyenziswa kwizicelo apho ukukhuhlana okuphantsi kunqweneleka, njengakwiibheringi kunye netywina. PTFE ikwasisithinteli sombane esigqwesileyo, sisenza ukuba sibe luncedo kusetyenziso lombane.
Enye yezona zicelo ezaziwa kakhulu ze PTFE ikwizitya zokupheka ezinganamatheli. Iimpawu zokungancamatheli ze PTFE zibangelwa amandla ayo asezantsi, nto leyo ethintela ukutya ekuncameleni kumphezulu we-cookware. PTFE ikwasetyenziswa kwezinye izicelo apho iipropati ezinganamatheli zifunwayo, ezinje ngokugqunywa kwezixhobo zonyango kunye nokwenziwa kweegaskets kunye netywina.
PTFE Ikwasetyenziswa kwishishini le-aerospace ngenxa yokumelana nobushushu obuphezulu kunye ne-coefficient ephantsi yokukhuhlana. Isetyenziswa ekwenzeni amacandelo eenjini zenqwelo-moya, ezifana nezitywina kunye neebheringi. PTFE ikwasetyenziswa ekwakhiweni kweesuti zasemajukujukwini ngenxa yokukwazi ukumelana namaqondo obushushu agqithisileyo kunye neempawu zayo zokungakhuni.
Ukongeza kusetyenziso lwayo kwiingubo ezingabambekiyo kunye nezicelo ze-aerospace, PTFE ikwasetyenziswa xa kusenziwa ezinye izinto ezahlukahlukeneyo, njengeentambo zekhompyutha, iinxalenye zeenqwelo-mafutha, nezaleko zemizi-mveliso. Ikwasetyenziselwa ukuveliswa kwendwangu ye-Gore-Tex, into engenamanzi kunye nefuthe eliphefumulayo elisetyenziswa kwiimpahla zangaphandle kunye nezihlangu.
Ukuququmbela, PTFE yimathiriyeli eguquguqukayo eneempawu ezizodwa ezenza ukuba luncedo kuluhlu olubanzi lwezicelo. Ubume bayo obungaguqukiyo, i-coefficient ephantsi ye-friction, kunye nokumelana nobushushu obuphezulu kuyenza ibe lolona khetho lubalaseleyo lokusetyenziswa kwi-non-stick coatings, amacandelo e-aerospace, kunye nezinye izicelo zemizi-mveliso.
