Kupfekedzwa kwepolymer kana polytetrafluoroethylene pane cookware inoburitsa isingabatike pamusoro.Inowanikwa kweanopfuura makore makumi matanhatu, polymer inobatsira kudzivirira mazai nemapanike kubva kunamira mu skillet.Nehurombo, iyo polymer yekuputira machipisi kana yakakweshwa neyakaomarara-yakagadzika midziyo yekubikira kana abrasive scouring pads.Kumwe kunetseka kunosanganisira perfluorooctanoic acid kana PFOA, kemikari inoshandiswa seyamuro yekugadzirisa yepolymer.Yakabatanidzwa negomarara mumhuka dzerabhoritari.Nekudaro, cookware yakavharwa nepolymer inonzi yakachengeteka kushandisa, kunyangwe yakakweshwa.
Izvo zvave zvichizivikanwa zvakanyanya kwemakore kuti kuratidzwa kwevanhu kuPFOA kwakadzikira zvakanyanya pasi peyakajairwa isiri-stick cookware kushandiswa mamiriro.Chidzidzo chichangobva kuburitswa nevechitatu bato rinovimbwa, Consumer Reports, yaratidza zvakare kuti njodzi yekusashandisa pani isina tsvimbo yakadzikira, uye ichidzikira."Consumer Reports yakaedza mapani asina-tsvimbo kubva kune vakasiyana-siyana vanogadzira kuti vaedze kuchengetedzeka kwemapani matsva uye akashandiswa pakupisa kwe204 C (400 F) ndokuona kuti kuburitswa kwePFOA kwaive kushoma.“Chimwero chepamusoro-soro chakanga chakaderera nekanenge ka100 pane mwero uyo zvidzidzo zvemhuka zvinokarakadza kuti une hanya nokuda kwokuratidzirwa kunopfuurira kuPFOA,” magazini yacho inoshuma kudaro muchinyorwa chayo chaJune."Nemapani akachembera, kubuda kwacho kwaisatombo kuyerwa."Health Canada yakataura kuti mabhanhire asina-tsvimbo akachengeteka kuti ashandiswe patembiricha iri pasi pe350 C (662 F).Asi, sangano remubatanidzwa rakati nekupisa kwakanyanya, hutsi hunoshatirisa kana hune chepfu hunogona kuburitswa.

Pfungwa dzekufunga nezvazvo:
Kana iwe ukabika pane tembiricha inopfuura 500 F, mafuta ekubika akajairika nemafuta ari, kana kuti angangosvika nekukurumidza, iyo "flash point."Nekudaro, uri kugadzira njodzi yakakomba yemoto wegirisi uye zvakare urikubvisa chikafu nemafuta, uye nekudaro kubudisa utsi nehutsi zvinogona kuve nengozi kuhutano hwako nehwechipfuwo chako, zvisinei nekuti rudziipanuri kushandisa!
PFOA-sekemikari inowedzerwa pakadzika zvakanyanya kune yakaomeswa fluoro-polymers kubatsira iyo isiri-tsvimbo yepolymer hupfu kunamatira, mune imwe hata layer, kune ichangopfuura yakadhindwa, kukanda, kana spun mapani, isati ya "kubikira" isiri-tsvimbo. polymer kupera.Munguva iyi yekubikira-pachikamu chekugadzira cookware, iyo yakawanda yasara PFOA-senge emulsifiers inotakurwa kuenda kune fume vent system kubva kune yakakwirira tembiricha yekugadzira oveni.Ndipo panodiwa vapor controls kuti uderedze kuratidzwa pabasa.
Iyo yakapararira bio-kuunganidzwa kwePFOA uye PFOA-senge zvinhu mumhando dzakawanda dzinodziya dzine ropa pasirese hazvigone kuve zvakanyanya kukonzerwa nekubika.Haasi masangano ese ane mukana kune asiri-stick cookware!Isu tinofanirwa kutarisa kune imwe PFOA senge mashandisirwo ekupedzisira ekuona kuti zvakakosha kuratidzwa kwemhuka kuri kubva kupi.
