Pani yopanda ndodo molingana ndi gulu la zokutira zopanda ndodo, zitha kugawidwa kukhala: Teflon zokutira poto yopanda ndodo ndi zokutira za ceramic zosakhala ndodo.
1. Kupaka kwa Teflon
Chophimba chodziwika bwino chopanda ndodo m'miyoyo yathu ndi ❖ kuyanika kwa Teflon, komwe kumadziwika kuti "polytetrafluoroethylene (PTFE)", ndi polima yokhazikika yopangidwa ndi anthu, samachita ndi zinthu zilizonse, asidi amphamvu amchere sangathandize.
Panthawi imodzimodziyo, PTFE ndi kagawo kakang'ono kwambiri kameneka kakukangana kolimba, kugwedezeka kotsika kwambiri, kotero kuti kutsekemera kwapamwamba ndi kutsika kwapansi kumapangitsa kuti kumagwiritsidwa ntchito kwambiri muzophika zopanda ndodo, kuthetsa vuto la ziwaya zomata zomwe zakhala zikuvutitsa. anthu kwa zaka zambiri.
The drawback yekha wa PTFE ndi kuti si kugonjetsedwa ndi kutentha kwambiri, ndipo adzayamba volatilize pamene usavutike mtima pa 260 ° C ndi kuyamba liquefy pa 327 ° C.Kodi zokutira zopanda ndodo ndizowopsa mthupi la munthu?Kodi zingayambitse khansa?Yakhala nkhani yodetsa nkhawa anthu, kwenikweni, sitiyenera kuda nkhawa nazo, pazifukwa zotsatirazi.
Choyamba, banja Frying, apamwamba kwambiri makumi asanu ndi awiri ndi makumi asanu ndi atatu peresenti ya kutentha mafuta, za 200 ℃, sikokwanira kuwononga PTFE;ngakhale mutawotcha kwambiri kutentha kwamafuta makumi asanu ndi anayi peresenti yotentha, muyenera kudandaula za zotsatira zovulaza za mbale zowotchedwa, osati Teflon yosasunthika.
Kafukufuku wapeza kuti mu nkhani ya oposa 400 ℃, PTFE kosakhazikika mpweya woopsa mbalame, palibe umboni kuti ndi zovulaza anthu, World Health Organization komanso m'gulu PTFE monga kalasi 3 carcinogenic zinthu, ndiye, ayi. umboni wovulaza, gulu lomwelo la zinthu monga caffeine, utoto wa tsitsi.
Zomwe zingayambitse mantha ndi zowonjezera za PFOA ndi PFOS popanga PTFE m'mbuyomu, zomwe zimatchedwa kuti carcinogenic zinthu m'gulu 2B.Kanemayo "Blackwater" akukhudzana ndi kuvulala komwe kumachitika chifukwa cha kutulutsa kwa PFOA mumtsinje.
Komabe, malo osungunuka a PFOA ndi PFOS ndi 52 ℃ okha, malo otentha a 189 ℃, monga tanenera kale, kutentha kwa kutentha kwa poto kumatha kupitirira 400 ℃, PFOA yatenthedwa kale, ndipo PFOA tsopano yatha. akhala oletsedwa kwa nthawi yayitali m'maiko ambiri, tadziperekanso KUPEKA KWABWINO zinthu zonse zilibe PFOA.
Choncho, simuyenera kudandaula za Teflon non-ndodo cookware adzabweretsa mavuto thanzi, khalani otsimikiza kuti ntchito
2. Chophimba cha ceramic
Chophimba cha ceramic si chotchinga chopanda ndodo chopangidwa ndi ceramic, ndi chophimba chopangidwa ndi mchere wachilengedwe ndi polymethylsiloxane fusion, ubwino wake ndi wotetezeka kuposa Teflon, wosagonjetsedwa ndi kutentha kwakukulu (450 ℃), maonekedwe a pulasitiki ndi amphamvu.
Komabe, zokutira zopanda ndodo za ceramic ndizotsika kwambiri kuposa poto yopanda ndodo ya Teflon, ndipo ndizosavuta kugwa, moyo wautumiki ndi waufupi kwambiri, ngati poto wamba wa Teflon wopanda ndodo ukupezeka kwa chaka chimodzi, ceramic non- poto yomata imatha kugwiritsa ntchito miyezi 1-2 yokha, mtengo wake ndi wotsika kwambiri, KUPHEKA KWABWINO sikuvomerezeka.
