Puas yog Teflon muaj kev nyab xeeb?

Hauv Asmeskas chav ua noj, Teflon coated pans ci. Lawv cov khawv koob yooj yim-rau-ntxuav? Txawm li cas los xij, cov lus ntxhi tshwm sim: 'PFOA li cas? Thiab kub kub?' Nyob rau hauv qhov kev nyiam ntawm Teflon cov khoom, kev txhawj xeeb simmer. Nrog cov dab neeg ntawm cov pa hluav taws xob polymer thiab cov lus nug txog kev nyab xeeb, peb pom peb tus kheej ntawm txoj kev hla. Stainless hlau thiab cam khwb cia hlau beckon, tab sis Teflon zaj dab neeg thov kom qhia. Cia peb dhia dej.

Teflon yog dab tsi?

Teflon yog lub npe lag luam, Ameslikas tsim los ntawm Chemours Company, rau ntau yam khoom raws li polytetrafluoroethylene (PTFE). Nws yog dav paub txog nws cov khoom uas tsis yog-stick thiab tau dhau los ua ib lub npe hauv tsev uas muaj cov khoom siv tsis-stick thiab ntau yam kev siv, xws li rwb thaiv tsev cable, seals, thiab txawm tias khaub ncaws.

Puas tau rub tawm lub lauj kaub zoo nkauj uas cog lus tias tsis muaj pluas tshais? Qhov ntawd yog cov khawv koob ntawm Teflon. Yug los ntawm kev sib raug zoo ntawm cov pa roj carbon thiab fluorine, Teflon cov khoom tau yeej lub ntiaj teb ntawm cov txheej txheem tsis zoo, hloov peb chav ua noj thiab ua kom huv si.

Tab sis ntawm no yog ib qho kev sib tw: ntxhi ntawm 'PFOA' lossis 'perfluorooctanoic acid' feem ntau ntab ncig Teflon sib tham. Keeb kwm txuas nrog Teflon cov txheej txheem tsim khoom, kev txhawj xeeb bubbed thaum Teflon coated cookware ntsib kub kub, hinting ntawm tej zaum cov fumes polymer. Ua tsaug, kev tsim kho tshiab tau nqis los. Niaj hnub no, ntau yam khoom siv Teflon hnav cov paib ntawm kev ua 'PFOA-dawb', kom ntseeg tau tias koj cov pancakes thiab kev thaj yeeb ntawm lub siab nyob hauv tes zoo.

Yog li, PFOA yog dab tsi? PFOA, luv luv rau perfluorooctanoic acid, yog cov khoom siv hluavtaws ib zaug siv dav hauv cov khoom siv tsis siv tshuaj thiab ntau yam khoom siv. Tsis tu ncua nyob rau hauv ib puag ncig thiab txuas nrog ntau yam kev txhawj xeeb txog kev noj qab haus huv, nws txoj kev siv tau raug cuam tshuam los ntawm cov tuam txhab tsim khoom hauv xyoo tas los no vim muaj kev xav txog kev nyab xeeb.

PTFE Coated yog dab tsi?

Polytetrafluoroethylene (PTFE) yog ib qho hluavtaws fluoropolymer ntawm tetrafluoroethylene. Nws yog cov yas ua haujlwm siab uas paub txog nws cov khoom tsis yog nplaum, kub tsis kam, thiab tshuaj lom neeg tsis kam. PTFE coated tuaj yeem siv rau ntau yam khoom, los ntawm cov lauj kaub mus rau cov khoom siv tshuab, los muab lawv ib tug du, tsis-reactive, thiab tsis-stick nto.

Thaum koj glide qe tawm ntawm koj lub lauj kaub nrog xoom fuss, koj tab tom ntsib qhov kev xav ntawm PTFE, feem ntau hu ua Teflon coated. Qhov no tsis yog qhov zoo kawg nkaus, yug los ntawm cov pa roj carbon thiab fluorine, ua rau cookware npau suav los lis thiab yooj yim los ntxuav.

Tab sis ntawm no yog qhov tseeb: cov khoom lag luam Teflon thaum ntxov tau cuam tshuam nrog 'PFOA', ua rau muaj kev ntxhov siab thaum cov khoom no tau ntsib cua sov, hinting ntawm cov pa hluav taws xob muaj peev xwm. Ceev nrooj rau hnub no, thiab ntau yam khoom siv Teflon khav theeb 'PFOA-dawb' daim paib, kom ntseeg tau tias koj qhov kev ua noj tsis zoo tsis cuam tshuam txog kev nyab xeeb.

Puas yog PTFE Phem Rau Koj?

Pure PTFE yog inert, ntawm nws cov tub ntxhais, PTFE, lub plawv ntawm ntau Teflon khoom, tseem tsis-reactive. Nws daim ntawv cog lus ntawm cov pa roj carbon thiab fluorine ua kom nws tsis muaj zog ntau. Txawm li cas los xij, ib qho hitch tshwm nrog kub kub. Ntawm qhov kub siab heev (feem ntau siab dua 570 ° F lossis 300 ° C), muaj peev xwm ua rau cov pa roj carbon monoxide, qee zaum ua rau 'polymer fume fever'.Yog hais tias, nyob rau hauv ib txwm ua noj ua haus, PTFE-coated cookware tsis ncav cuag cov kub no.

Ntxiv qhov wrinkle rau zaj dab neeg yog 'PFOA'. Ib zaug ib feem ntawm Teflon piav qhia, nws tsa pob muag vim kev txhawj xeeb txog kev noj qab haus huv ntawm qhov kub thiab txias. Txoj xov zoo? Niaj hnub no cov khoom Teflon zoo siab dais 'PFOA-dawb' stamp.

Hauv cov ntsiab lus, zoo li txhua yam cuab yeej hauv chav ua noj, Teflon cookware, thaum siv txoj cai, sib xyaw yooj yim nrog kev nyab xeeb.

Puas yog Teflon Toxic?

PTFE, nrog nws cov cim sib xyaw ntawm carbon thiab fluorine, sawv tawm rau nws cov tshuaj inertness. Qhov no txhais tau tias, nyob rau hauv ib txwm muaj mob, nws yog passive li lub stainless hlau lauj kaub koj yuav siv tau rau cov kua zaub los yog cov cam khwb cia hlau skillet rau koj seared steaks. Nws tsis cuam tshuam, nws tsuas cia zaub mov glide.

Txawm li cas los xij, thaum cov lus piav qhia hloov mus rau qhov kub siab, txhua yam tau tad steamy. Pushing nonstick cookware rau qhov kub thiab txias, dhau ntawm nws qhov kev pom zoo, tuaj yeem ua rau tso tawm cov pa hluav taws xob polymer. Qee tus neeg, thaum raug, yuav ntsib qhov tsis xis nyob luv luv hu ua 'polymer fume fever'.

Tom qab ntawd muaj qhov subplot ntawm 'PFOA'. Thaum ib zaug txuas rau cov txheej txheem tsim khoom ntawm qee cov khoom Teflon, kev txhawj xeeb txog kev noj qab haus huv ua rau kev lag luam pivot. Niaj hnub no, lub tsom teeb ci ci ntsa iab ntawm ntau yam khoom Teflon stamped nrog 'PFOA-dawb', ua pov thawj rau kev hloov pauv tas li.

Yog li, thaum teflon coated tau ua rau peb chav ua noj yooj yim-rau-huv havens, lawv tuaj nrog ib qho yooj yim mantra: hwm lawv cov kev txwv. Tuav nrog kev saib xyuas, PTFE zaj dab neeg yog ib qho kev siv hluav taws xob, tsis muaj tshuaj lom.

Puas yog Teflon Safe?

PTFE, ntawm nws lub siab, yog fusion ntawm carbon thiab fluorine. Cov tshuaj lom neeg daim ntawv cog lus khoom plig rau nws lub ntuj inertness, ua rau nws zoo nkauj phab ntsa. Ib yam li koj lub lauj kaub hlau stainless lossis cov hnub nyoog laus, nws tsis sib xyaw; nws yooj yim yooj yim.
Txawm li cas los xij, zoo li txhua tus neeg ua yeeb yam zoo, Teflon coated muaj nws cov kev nyiam theem. Nkag mus rau hauv qhov kub thiab txias, nce siab tshaj nws qhov chaw xis nyob, thiab koj yuav ntsib cov pa hluav taws xob polymer. Thaum lub sijhawm luv luv, qhov kis tau tuaj yeem ua rau tsis tshua muaj kev paub txog 'polymer fume fever'.

Cov lus piav qhia ntawm 'PFOA' ib zaug txuas rau hauv PTFE zaj dab neeg, ua rau muaj kev txhawj xeeb txog kev noj qab haus huv. Tab sis kev hloov pauv yog qhov tseem ceeb ntawm kev tsim kho tshiab. Niaj hnub no lub lag luam kab teeb nrog Teflon cov khoom lag luam zoo siab tshaj tawm 'PFOA-dawb' cov paib, qhia txog txoj kev tsim khoom zoo dua.

Hauv kev ua yeeb yam loj ntawm kev ua noj ua haus, nrog kev saib xyuas zoo, PTFE hauv cov txheej txheem tsis zoo tseem yog tus tswv cuab cam khwb cia. Nws cog lus yooj yim-rau-huv interludes thiab efficiency, tsis muaj kev cuam tshuam kev nyab xeeb lub tsom teeb.Thaum siv kom raug, PTFE-coated khoom muaj kev nyab xeeb. Nws yog ib qho tseem ceeb rau:
1.Tsis txhob overheating: Tsis txhob tawm hauv koj lub PTFE-coated cookware rau kub kub rau lub sij hawm ntev.
2. Siv Cov Khoom Siv Yooj Yim: Tsis txhob siv cov hlau lossis cov khoom ntse uas tuaj yeem khawb thiab ua kom cov txheej txheej.
3.Purchase los ntawm Reputable Manufacturers: Xyuas kom cov khoom muaj ntawv pov thawj PFOA-dawb thiab ua raws li cov qauv kev nyab xeeb thiab zoo.
