Tuag-cam khwb cia txhuas yog ib lub teeb yuag hlau nrog cov khoom xws li corrosion kuj, hluav taws xob conductivity thiab tsawg melting point. Vim nws muaj ntau yam khoom tshwj xeeb, nws yog ib qho khoom siv rau ntau yam kev siv. Ntawm lawv, cov txheej txheem feem ntau siv rau cov ntaub ntawv txhuas yog tuag casting. Tuag casting yog cov txheej txheem tsim tau zoo uas tuaj yeem tsim cov duab nyuaj thiab cov qauv nrog kev ua haujlwm siab thiab sib xws.
Txawm hais tias muaj ntau yam txiaj ntsig ntawm txhuas tuag-cam khwb cia, muaj qee qhov kev txhawj xeeb txog nws txoj kev nyab xeeb. Qhov kev txhawj xeeb tseem ceeb yog kev txhawj xeeb tias kev siv cov khoom siv txhuas los yog lwm cov khoom siv txhuas tuaj yeem ua rau cov txhuas nkag mus rau hauv cov zaub mov thiab thaum kawg ua rau muaj teeb meem kev noj qab haus huv.
Tab sis puas tuag-cam khwb cia txhuas muaj kev nyab xeeb? Muaj ntau cov lus teb, nyob ntawm seb qhov kev thov tshwj xeeb thiab kev siv cov khoom siv.
Ua ntej, nws tseem ceeb heev uas yuav tsum nco ntsoov tias muaj ntau hom txhuas, tsis yog ib qho loj xwb. Piv txwv li, tsis muaj kev kho aluminium yog qhov muaj zog heev nrog cov kua qaub thiab cov hauv paus, uas tuaj yeem ua rau xeb thiab ua rau muaj kev phom sij. Tias yog vim li cas feem ntau aluminium cookware yog coated nrog ib tug nonstick txheej los yog anodized los tiv thaiv cov txhuas los ntawm leaching.
Nyob rau hauv cov ntaub ntawv ntawm txhuas tuag-casting, cov khoom yog feem ntau kho nrog ib tug txheej uas pab tiv thaiv corrosion thiab leaching. Cov txheej txheej, hu ua ceramic los yog enamel, tsim ib qho kev thaiv ntawm cov txhuas thiab cov khoom noj, ua kom nws muaj kev nyab xeeb thiab tsis muaj cov kab mob phem.
Tsis tas li ntawd, ntau niaj hnub tuag-cam khwb cia aluminium cookware yog tsim los nrog kev nyab xeeb hauv siab. Piv txwv li, lawv tau ua los ntawm cov ntaub ntawv zoo thiab ua tiav uas tsis muaj tshuaj lom neeg xws li PFOA thiab PFAS. Tsis tas li ntawd, lawv feem ntau yog tsim los ua kom tau raws li FDA nruj thiab cov qauv kev nyab xeeb.
Lwm qhov tseem ceeb uas yuav tsum tau xav txog yog kev saib xyuas kom zoo thiab kev saib xyuas ntawm cov khoom siv txhuas tuag. Txhawm rau kom ntseeg tau tias nws muaj kev nyab xeeb thiab siv tau ntev, nws yog ib qho tseem ceeb kom tsis txhob muaj cov khoom siv tawv tawv los yog cov khoom siv hlau uas tuaj yeem khawb qhov chaw thiab ua rau muaj kev puas tsuaj. Nws yog ib qho tseem ceeb kom tsis txhob muaj cov khoom noj acidic lossis alkaline uas tuaj yeem hnov mob nrog txhuas thiab ua rau leaching.
Zuag qhia tag nrho, txhuas tuag-cam khwb cia feem ntau muaj kev nyab xeeb rau kev siv hauv kev npaj zaub mov thiab muaj kev nyab xeeb thaum siv kom raug thiab nrog kev saib xyuas kom raug. Nws muaj ntau yam tshwj xeeb, ua ke nrog kev tsim khoom niaj hnub thiab cov qauv kev nyab xeeb, ua rau nws muaj kev xaiv nrov rau cookware thiab lwm yam kev siv. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov ua tib zoo saib xyuas cov ntawv thov tshwj xeeb thiab siv cov khoom siv kom ntseeg tau tias nws muaj kev nyab xeeb thiab ua haujlwm tau zoo.
