Kodi Teflon ndi yotetezeka?

M'makhitchini aku America, mapepala ophimbidwa ndi Teflon amawala. Matsenga awo osavuta kuchotsa? Ndi nthano zamafusi a polima ndi mafunso okhudzana ndi chitetezo, timapezeka pamphambano. Chitsulo chosapanga dzimbiri ndi chitsulo choponyedwa chimakopa, koma nkhani ya Teflon ikupempha kuti inene. Tiyeni tilowe m'madzi.

Kodi Teflon ndi chiyani?

Teflon ndi dzina lachizindikiro, lopangidwa ndi Chemours Company, pazinthu zingapo zozikidwa makamaka pa polytetrafluoroethylene (PTFE). Amadziwika kwambiri chifukwa chosagwiritsa ntchito ndodo ndipo asanduka dzina lapakhomo lofanana ndi zophikira zopanda ndodo komanso ntchito zina zosiyanasiyana, monga kutsekereza chingwe, zisindikizo, ngakhale zovala.

Munatulutsapo poto wonyezimira uja womwe umalonjeza chakudya cham'mawa chopanda ndodo? Ndiwo matsenga a Teflon. Zopangidwa kuchokera ku mgwirizano wapakati pa kaboni ndi fluorine, Zogulitsa za Teflon zidatsogolera dziko lonse la zokutira zopanda ndodo, kusintha makhitchini athu ndikupanga kuyeretsa kukhala kamphepo.

Koma apa pali kupotoza kwachiwembu: kunong'onezana kwa 'PFOA' kapena 'perfluorooctanoic acid' nthawi zambiri kumayandama pazokambirana za Teflon. Zakale zokhudzana ndi kupanga kwa Teflon, nkhawa zidakula pamene zophikira za Teflon zophikira zidakumana ndi kutentha kwakukulu, kutengera utsi womwe ukhoza kukhala wa polima. Mwamwayi, luso linachitapo kanthu. Masiku ano, zinthu zambiri za Teflon zimavala baji ya 'PFOA-free', kuwonetsetsa kuti zikondamoyo zanu zonse ndi mtendere wamumtima zili m'manja mwabwino.

Ndiye, PFOA ndi chiyani?PFOA, chachidule cha perfluorooctanoic acid, ndi chinthu chopangidwa kale chomwe chimagwiritsidwa ntchito kwambiri muzophika zopanda ndodo ndi zinthu zina zosiyanasiyana. Kukhazikika m'chilengedwe komanso kulumikizidwa ndi zovuta zingapo zaumoyo, kugwiritsidwa ntchito kwake kwathetsedwa kwambiri ndi opanga m'zaka zaposachedwa chifukwa chachitetezo.

Kodi PTFE Coated ndi Chiyani?

Polytetrafluoroethylene (PTFE) ndi fluoropolymer yopanga ya tetrafluoroethylene. Ndi pulasitiki yogwira ntchito kwambiri yomwe imadziwika chifukwa chosagwira ndodo, kukana kutentha kwambiri, komanso kukana mankhwala. The PTFE TACHIMATA angagwiritsidwe ntchito zosiyanasiyana mankhwala, kuchokera mapoto kuti makina zigawo zikuluzikulu, kuwapatsa malo osalala, osasunthika, komanso osamata.

Mukathamangitsa dzira pa poto yanu ndi kukangana zero, mukukumana ndi zodabwitsa za PTFE, zomwe zimadziwika kuti Teflon zokutira. Chodabwitsa chopanda ndodochi, chobadwa kuchokera ku carbon ndi fluorine, chimapangitsa zophikira kukhala loto kugwira komanso zosavuta kuyeretsa.

Koma apa pali zina: Zogulitsa zoyambilira za Teflon zidalumikizana ndi 'PFOA', zomwe zidayambitsa chipwirikiti zinthu izi zitakumana ndi kutentha kwakukulu, kuwonetsa utsi womwe ungachitike. Posachedwa mpaka lero, ndipo zinthu zambiri za Teflon zimadzitamandira ndi baji ya 'PFOA-free', kuwonetsetsa kuti kuphika kwanu mosavutikira sikusokoneza chitetezo.

Kodi PTFE Ndi Yoyipa Kwa Inu?

PTFE yoyera ndi inert, pachimake, PTFE, mtima wa zinthu zambiri za Teflon, zimakhalabe zopanda mphamvu. Mgwirizano wake wa kaboni ndi fluorine umatsimikizira kuti sichimangokhala. Komabe, kugunda kumawoneka ndi kutentha kwakukulu. Pa kutentha kwambiri (nthawi zambiri pamwamba 570 ° F kapena 300 ° C), pali kuthekera polima fumes, nthawi zina kuchititsa 'polymer fume fever'.That anati, pansi bwino kuphika, PTFE- TACHIMATA cookware safika kutentha uku.

Kuwonjezera makwinya pankhaniyi ndi 'PFOA'. Kamodzi mbali ya nkhani ya Teflon, idakweza nsidze chifukwa cha nkhawa zathanzi pakutentha kwambiri. Nkhani yabwino? Zogulitsa zamasiku ano za Teflon monyadira zimakhala ndi sitampu ya 'PFOA-free'.

Mwachidule, monga chida chilichonse kukhitchini, Teflon cookware, ikagwiritsidwa ntchito moyenera, imaphatikizana mosavuta ndi chitetezo.

Kodi Teflon Ndi Yowopsa?

PTFE, ndi kuphatikiza kwake kwapadera kwa carbon ndi fluorine, imadziwika kwambiri chifukwa cha kusakhazikika kwamankhwala. Izi zikutanthauza kuti, nthawi zonse, zimakhala ngati mphika wosapanga dzimbiri womwe mungagwiritse ntchito ngati supu kapena skillet wachitsulo wa steak wanu. Sichimalumikizana, chimangolola kuti chakudya chiziyenda.

Komabe, pamene nkhaniyo ikupita ku kutentha kwakukulu, zinthu zimakhala zovuta kwambiri. Kukankhira zophikira zopanda ndodo mpaka kutentha kwambiri, kupitirira momwe akufunira, kungayambitse kutulutsa utsi wa polima. Anthu ena, akawululidwa, amatha kumva kusapeza kwakanthawi komwe kumatchedwa 'polymer fume fever'.

Kenako pali gawo la 'PFOA'. Pomwe zidalumikizidwa ndi kupanga kwazinthu zina za Teflon, nkhawa zokhudzana ndi thanzi zidapangitsa kuti mafakitale azikhala patsogolo. Masiku ano, kuwala kumawala kwambiri pazinthu zambiri za Teflon zosindikizidwa ndi 'PFOA-free', umboni wa kusinthika kosalekeza.

Chifukwa chake, ngakhale zokutidwa ndi teflon zapangitsa khitchini yathu kukhala malo osavuta kuyeretsa, amabwera ndi mawu osavuta: kulemekeza malire awo. Ikagwiridwa mosamala, nthano ya PTFE ndi imodzi yothandiza, osati poizoni.

Kodi Teflon Ndi Yotetezeka?

PTFE, pamtima pake, ndi kuphatikiza kwa carbon ndi fluorine. Chomangira chamankhwala ichi chimapatsa mwayi wokhazikika wachilengedwe, ndikupangitsa kuti maluwawo akhale ngati khoma. Monga mphika wanu wodalirika wachitsulo chosapanga dzimbiri kapena chitsulo chazaka zakale, sichisakanizika; zimangothandizira.
Komabe, monga wosewera wabwino aliyense, Teflon wokutidwa ali ndi magawo omwe amakonda. Lowani kutentha kwambiri, kupitilira malo ake otonthoza, ndipo mutha kukumana ndi utsi wa polima. Ngakhale kukakhala kwakanthawi kochepa, kuwonetseredwa kungayambitse matenda a 'polymer fume fever'.

Nkhani ya 'PFOA' idalowa munkhani ya PTFE, ndikuyambitsa nkhawa zaumoyo. Koma kusintha ndiko maziko a luso. Msika wamasiku ano ukuyenda ndi zinthu za Teflon monyadira mabaji a 'PFOA-free', kuwonetsa njira yopangira chitetezo.

Pochita bwino kwambiri zamaluso ophikira, ndi chisamaliro choyenera, PTFE mu zokutira zopanda ndodo imakhalabe membala wodalirika. Imalonjeza zophatikizira zosavuta kuyeretsa komanso kuchita bwino, popanda kusokoneza kuwala kwachitetezo.Zikagwiritsidwa ntchito moyenera, zinthu zokutidwa ndi PTFE ndizotetezeka. Ndikofunikira kuti:
1.Pewani Kutentha Kwambiri:Osasiya zophikira zanu zokutidwa ndi PTFE pa kutentha kwakukulu kwa nthawi yayitali.
2.Gwiritsani Ntchito Zida Zofatsa: Pewani zitsulo kapena zinthu zakuthwa zomwe zimatha kukanda ndikuwononga zokutira.
3.Kugula kwa Opanga Odalirika: Onetsetsani kuti malondawo ndi ovomerezeka a PFOA ndipo amatsatira mfundo za chitetezo ndi khalidwe.
