ʻO ka uhi ʻana o ka polymer a i ʻole polytetrafluoroethylene ma luna o nā mea kuke e hana i kahi ʻili nonstick.Loaʻa no nā makahiki ʻoi aku ma mua o 60, kōkua ka polymer i ka pale ʻana i nā hua a me nā pancakes mai ka hoʻopili ʻana i kahi skillet.ʻO ka mea pōʻino, hemo ka puʻupuʻu polimer i ka wā e ʻoki ʻia ai e nā mea kīhini ʻeleʻele a i ʻole nā pad abrasive.ʻO kekahi hopohopo e pili ana i ka perfluorooctanoic acid a i ʻole PFOA, kahi kemika i hoʻohana ʻia ma ke ʻano he kōkua hana no ka polymer.Ua hoʻopili ʻia i ka maʻi kanesa i nā holoholona lab.Eia nō naʻe, ua manaʻo ʻia nā mea kuke i uhi ʻia i ka polymer i palekana ke hoʻohana, ʻoiai inā ʻoki ʻia.
Ua ʻike nui ʻia no nā makahiki he haʻahaʻa loa ka hōʻike ʻana o ke kanaka i ka PFOA ma lalo o nā kūlana hoʻohana maʻamau o ka mea kuke ʻole.ʻO kahi hōʻike noiʻi i hoʻokuʻu wale ʻia e kahi ʻaoʻao ʻekolu i hilinaʻi ʻia, Consumer Reports, ua hōʻoia hou i ka haʻahaʻa o ka hoʻohana ʻana i ka pan non-stick, a me ka haʻahaʻa.“Ua hoʻāʻo ʻo Consumer Reports i nā pā non-stick mai nā mea hana like ʻole e hoʻāʻo i ka palekana o nā pā hou a hoʻohana ʻia i ka wela o 204 C (400 F) a ʻike ʻia he liʻiliʻi nā hoʻokuʻu PFOA."ʻO ka pae kiʻekiʻe ma kahi o 100 mau manawa haʻahaʻa ma mua o nā pae i hōʻike ʻia e nā haʻawina holoholona e hopohopo nei no ka hoʻomau mau ʻana i ka PFOA," i hōʻike ʻia e ka makasina ma kāna pukana Iune."Me nā pā kahiko, ʻaʻole hiki ke ana ʻia nā emissions."Ua ʻōlelo ʻo Health Canada he palekana ka hoʻohana ʻana i nā pale non-stick i nā mahana ma lalo o 350 C (662 F).Akā, ua ʻōlelo ke keʻena federal me nā wela kiʻekiʻe, hiki ke hoʻokuʻu ʻia nā uahi ʻawaʻawa.
Nā mea e noʻonoʻo ai:
Inā ʻoe e kuke i ka mahana ma luna o 500 F, aia nā ʻaila maʻamau a me nā ʻaila, a i ʻole e hiki koke ana i ka "flash point."No laila, ke hana nei ʻoe i kahi pōʻino koʻikoʻi o ke ahi momona a ke hoʻohaumia nei hoʻi i nā meaʻai a me nā momona, a pēlā e hoʻokuʻu ai i ka uahi a me nā mahu e pōʻino ai kou olakino a me kāu pipi, ʻoiai ke ʻano o ke ʻano.panke hoʻohana nei ʻoe!
Hoʻohui ʻia nā kemika like me ka PFOA ma nā haʻahaʻa haʻahaʻa loa i ka pauka fluoro-polymers e kōkua i nā pauka polymer non-stick e hoʻopili, ma kahi ʻāpana like, i nā pā i hoʻopaʻa ʻia, hoʻolei, a milo paha, ma mua o ka "ʻauʻau" i ka lāʻau ʻole. hoʻopau polimer.I loko o kēia hana hoʻomoʻa ʻana i nā mea kuke, ua hoʻokuʻu ʻia ka nui o nā emulsifiers like me PFOA i kahi ʻōnaehana hū mai nā umu hana wela kiʻekiʻe.ʻO ia kahi e pono ai nā mana mahu e hōʻemi i ka ʻike hana.
ʻO ka laha ʻana o ka bio-accumulation o PFOA a me PFOA-like me nā mea i loko o nā ʻano koko wela a puni ka honua, ʻaʻole paha e pili nui ʻia i ka mea kuke.ʻAʻole hiki i nā hui āpau ke loaʻa i nā mea kuke non-stick!Pono mākou e nānā i nā PFOA ʻē aʻe e like me ka hoʻohana hope ʻana e hoʻoholo ai i kahi e hele mai ai nā hōʻike holoholona nui.
