Yembula ukusetshenziswa okubanzi kwe-Teflon, kusukela ezitsheni ezinganamathi kuya emishinini yezimboni. Funda ukuthi i-Teflon isetshenziselwa ini kanye nokuguquguquka kwayo okumangalisayo kuyo yonke imikhakha.

I-Polytetrafluoroethylene yatholwa ngo-1938. Ekuqaleni yatholwa usokhemisi waseMelika u-Roy J. Plunkett (1910–1994) ngenkathi ezama ukwenza isiqandisi esisha sekhabhoni ne-fluorine.

Phakathi komsindo wamapani ambozwe yi-Teflon, kuphakama ukuhlebeza: Ingabe i-Teflon iphephile phakathi nokushisa okuphezulu nokukhathazeka kwe-PFOA? Ake sembule iqiniso ngemuva kwemikhiqizo ye-Teflon.

I-ETFE ishintsha indlela esicabanga ngayo nge-greenhouse design. Sizohlola izimangaliso zokwakhiwa kolwelwesi lwe-ETFE nokuthi le filimu engavamile ye-ETFE ilichaza kanjani kabusha ikusasa lokwakha okusimeme.

Hlola umlingo we-nonstick cookware! Funda mayelana namapani e-PTFE ahlanganiswe nawe-ceramic. Kuyini ukunameka epanini elingagxili? Yembula isayensi ngemuva kwenguquko ye-nonstick.

'Ukuze unqume ukuthi amabhodwe akho namapani ane-Teflon yini, wahlolele i-non-stick coating. Ukwengeza, buyekeza ukupakishwa komkhiqizo kwelogo ye-Teflon, uqiniseke ukuthi unazo izinto zokupheka ezinalokhu kwaziswa okungagxili.'

Ipani elinganamathi ngokuvamile lenziwa ngezinto eziyisisekelo njenge-aluminium noma insimbi engagqwali. Isici sayo sesignesha siwukunamathela, okwenziwe ngokuyinhloko nge-polytetrafluoroethylene (PTFE) noma ngezinye izikhathi i-ceramic, eqinisekisa ukuthi ukudla akunamatheli phezulu, okwenza ukupheka nokuhlanza kube lula.

Wake wazibuza, 'Ingabe i-soldering izoncibilikisa itheyiphu ye-teflon?' Ngena ujule kusayensi namandla wetheyiphu ye-teflon lapho ubhekene namazinga okushisa okushisa. Thola imininingwane ebalulekile yokuqinisekisa ukuxhumana okuvikelekile, okungavuzi kuyo yonke imizamo yakho yokufaka amapayipi.'

Ngena ujule engxoxweni yeTeflon vs Nylon. Kusukela emandleni emishini, ukumelana nokugqokwa, ukuya ekumunceni umswakama, lesi sihloko sihlukanisa izimfanelo zabo ezihlukile kanye nezicelo. Zihlomise ngolwazi lokunquma okufanelekela kangcono impumelelo yephrojekthi yakho.

Thola ukubambezeleka komlilo kwe-PVC ne-Teflon. Funda mayelana nezakhiwo zabo, ukumelana nokushisa, nokuningi esihlokweni sethu esinolwazi. Gxumela namuhla!
