Ingabe iTeflon iphephile?

Ekhishini laseMelika, amapani we-teflon ehlanganisiwe akhanye. Umlingo wabo olula wokuhlanza? Noma kunjalo, ukucwilisa kuphakama: 'Kuthiwani ngePFOA? Nokushisa okuphezulu? Ngezinganekwane ze-polymer fumes nemibuzo ngokuphepha, sizithola sisesiphambanweni. Insimbi engenasici kanye ne-iron beckon, kepha indaba kaTeflon icela ukutshelwa. Masingene.

Yini i-teflon?

I-Teflon yigama lomkhiqizo, ekuqaleni elihlanganiswe yi-Chemours Company, ngohlobo lwemikhiqizo esekelwe ikakhulu ku-polytetrafluoroethleene (PTFE). Yaziwa kabanzi ngezakhiwo zayo ezingezona izinti futhi isibe yigama lezindlu liyafana ne-cookware okungeyona invimba kanye nezinye izinhlelo zokusebenza, njengokufakwa kwekhebula, izimpawu zekhebula, kanye nezingubo.

Wake wakhipha lelo ntanga ebusayo ethembisa ibhulakufesi elingenamkhawulo? Lowo ngumlingo we-teflon. Ukuzalwa kusuka esibophweni phakathi kwekhabhoni ne-fluorine, imikhiqizo ye-teflon iqhutshwa umhlaba wezembatho, ukuguqula amakhishi ethu nokwenza ukuhlanza umoya.

Kepha nansi i-Plot Twist: I-Whispers of 'PFOA' noma 'Pumpoorooctooctanoic acid' imvamisa iyantanta ezingxoxweni ze-teflon. Ngokomlando oxhumene nenqubo yokukhiqiza yeTeflon, ukukhathazeka kukhuphuke lapho i-teflon ehlanganisiwe cooraware yahlangana nokushisa okuphezulu, kuwupenda emafulethini we-polymer. Ngenhlanhla, ukusungulwa kwezinto kungene ngaphakathi. Namuhla, imikhiqizo eminingi ye-teflon igqoka ibheji lokuba 'Pfoa-free', Ukuqinisekisa ukuthi ama-pancake akho nokuthula kwengqondo kusezandleni ezinhle.

Ngakho-ke, yini i-PFOA? Ukuphikelela emvelweni futhi kuxhunyaniswe nezinkinga eziningana zezempilo, ukusetshenziswa kwayo kuvalwe kakhulu ngabakhiqizi eminyakeni yamuva ngenxa yokucatshangelwa kokuphepha.

Yini i-PTFE ehlanganiswe?

I-Polytetrafluoroethylene (PTFE) iyi-fluoropolymer yokwenziwa ye-tetrafluoroethyleneene. Kuyipulasitiki ephezulu kakhulu eyaziwa ngezakhiwo zayo ezingezona izinti, ukumelana okushisa okuphezulu, kanye nokumelana kwamakhemikhali. I-PTFE ehlanganisiwe ingafakwa kwimikhiqizo ehlukahlukene, kusuka kumapani kuya ezingxenyeni zomshini, Ukubanika indawo ebushelelezi, engasebenzi, futhi engeyona induku.

Lapho usula iqanda epanini lakho nge-zero disk, ubhekene nezimangaliso ze-PTFE, ezaziwa kakhulu ezaziwa ngokuthi iTeflon ehlanganiswe. Le malcel engaphenduki, izalwe kusuka kwikhabhoni nase-fluorine, yenza i-cookware ibe yiphupho ukuphatha futhi kulula ukuyihlanza.

Kepha nansi i-TIDBIT: Imikhiqizo yokuqala yeTeflon uma ihlanganiswe ne-'Pfoa ', ibangela isivuvukala lapho lezi zinto zihlangana khona ukushisa okuphezulu, okuvinjelwe ku-polymer fumes. Phendula phambili ku-Namuhla, futhi imikhiqizo eminingi ye-teflon igabha ibheji 'le-PFOA-free', ukuqinisekisa ukuthi ukupheka kwakho okungenamandla akushintshi ngokuphepha.

Ngabe i-PTFE ikubi kuwe?

I-PTFE Emsulwa i-inert, e-Core yayo, i-PTFE, inhliziyo yemikhiqizo eminingi ye-teflon, ihlala ingasebenzi. Isibopho saso sekhabhoni ne-fluorine siqinisekisa ukuthi kungamangalisa kakhulu. Kodwa-ke, ukushaya kuvela ngokushisa okuphezulu. Emazingeni okushisa aphakeme kakhulu (ngokuvamile ngenhla kwe-570 ° F noma i-300 ° C), kwesinye isikhathi i-polymer fumes, kwesinye isikhathi kubangela 'i-polymer futus fever'.Thembekele ngaphansi kwezimo zokupheka, ngaphansi kwezimo zokupheka ezijwayelekile azifinyeleli la mazinga okushisa.

Ukungeza umbimbi kwiTale ngu-'Pfoa '. Lapho nje ingxenye ye-teflon ilandisa, yaphakamisa amashiya ngenxa yokukhathazeka ngempilo emazingeni okushisa aphezulu. Izindaba Ezinhle? Imikhiqizo yanamuhla yeTeflon ngokuziqhenya ithwala isitembu se- 'PFOA-free'.

Kafushane nje, njenganoma yiliphi ithuluzi ekhishini, i-cookware teflon, lapho isetshenziswa kwesokudla, kuxubana kalula ngokuphepha.

Ingabe iTeflon Fotic?

I-PTFE, ngenhlanganisela yayo eyingqayizivele yekhabhoni ne-fluorine, ivelele amandla alo wamakhemikhali. Lokhu kusho, ngaphansi kwezimo ezijwayelekile, kunjengembiza yensimbi engagqwali ongayisebenzisa amasobho noma i-cast iron skillet yama-steak akho abekiwe. Akuhlangani, kumane kuvumela ukudla glide.

Kodwa-ke, lapho ukulandisa kuguquka ekushiseni okuphezulu, izinto zithola i-tad steamy. Ukucindezela ama-cookware angawona amazinga okushisa athe xaxa, ngaphezu kwebanga lawo anconyiwe, kungaholela ekukhishweni kwe-polymer fumes. Abanye abantu, lapho kuvezwa, bangathola ukungakhululeki okuphilayo okufingqiwe okwaziwa ngokuthi 'polymer fuume fever'.

Bese kuba nengxabano ye-'PFoa '. Ngenkathi ixhumeke kwinqubo yokukhiqiza yemikhiqizo ethile yeTeflon, ukukhathazeka ngemiphumela yezempilo eyenziwe izimboni. Namuhla, i-Spotlight ikhanya ngokugqamile emikhiqizweni eminingi ye-teflon egxishwe nge-'Pfoa-free ', iTestamente lokuziphendukela kwemvelo okuqhubekayo.

Ngakho-ke, ngenkathi uTeflon ehlanganisiwe enza amakhishi ethu ahlanze kube lula ukuwahlanza, eza ne-mantra elula: hlonipha imikhawulo yabo. Iphathwe ngokunakekelwa, inganekwane yePTFE ingenye yezisetshenziswa, hhayi ubuthi.

Ingabe iTeflon iphephile?

I-PTFE, enhliziyweni yayo, ingukuhlanganiswa kwekhabhoni ne-fluorine. Lesi sibopho samakhemikhali siyithola kungukuhlanzeka okungokwemvelo, okwenza kube yindawo ebonakalayo. Njengebhodwe lakho lensimbi elingenasici noma i-iron eneminyaka yobudala ubudala, ayihlangane; kumane kusizakale.
Kodwa-ke, njenganoma yimuphi umlingisi omuhle, i-teflon ehlanganisiwe inezilungiselelo zayo ezithandwayo zesigaba. I-Ventur Venture emazingeni okushisa aphezulu, ikhuphuka ngaphezu kwendawo yayo yokududuza, futhi ungahlangabezana ne-polymer fumes. Ngenkathi kuphila isikhashana, ukubonakaliswa kungaholela kumhlaseli ovamisile 'we-polymer futue fever'.

Ukulandisa kwe-'PFoa 'kwake kwaqhamuka ku-PTFE Tale, kukhanyisa ukukhathazeka ngempilo. Kepha ushintsho luwumqondo wobuciko obusha. Imishayo yemakethe yanamuhla enemikhiqizo yeTeflon eqhosha ngokuziqhenya ngebheji 'PFOA-free', ukusayina inqubo ephephile yokukhiqiza.

Ekusebenzeni okuhle kobuciko be-Culinary, ngokunakekelwa okulungile, i-PTFE kwezingubo ezingezona ama-nonstick ihlala iyilungu le-cast ethembekile. Ithembisa ukuhlangana okulula nokuhlanza okuhlanzekile nokusebenza kahle, ngaphandle kokuyekethisa indawo yokuphepha.Use kusetshenziswe kahle, imikhiqizo ehlanganiswe kahle ye-PTFE iphephile. Kubalulekile ku:
1.I-1.avoid ngokweqile: ungalokothi ushiye i-cookware yakho ye-PTFE-eboshwe ngokushisa okuphezulu isikhathi eside.
2.Sebenzisa izitsha ezimnene: Gwema izinto zensimbi noma ezibukhali ezingaqala futhi zinciphise ukunamathela.
I-3.Purchasese kusuka kubakhiqizi abadumile
