Ua palekana anei ʻo Teflon?

I loko o nā lumi kuke ʻAmelika, ʻālohilohi nā pā i uhi ʻia ʻo Teflon. ʻO kā lākou mea kilokilo maʻalahi e hoʻomaʻemaʻe? Akā, ua ala mai nā hāwanawana: 'Pehea e pili ana i ka PFOA? A me ka wela kiʻekiʻe?' Ma waena o ka hoʻowalewale o nā huahana Teflon, e hopohopo nei. Me nā moʻolelo o ka uahi polymer a me nā nīnau e pili ana i ka palekana, ʻike mākou iā mākou iho ma ke alahaka. ʻO ke kila kila a me ka hao hoʻolei ʻia, akā ke noi nei ka moʻolelo o Teflon e haʻi ʻia. E luʻu kākou.

He aha ka Teflon?

He inoa inoa ʻo Teflon, i hoʻokumu mua ʻia e ka Hui Chemours, no ka nui o nā huahana i hoʻokumu ʻia ma polytetrafluoroethylene (PTFE). Ua ʻike nui ʻia ʻo ia no kāna mau waiwai non-stick a ua lilo ia i inoa ʻohana e like me ka mea kuke ʻole a me nā ʻano hana ʻē aʻe, e like me ka insulation cable, sila, a me nā lole.

Ua huki ʻoe i kēlā pā nani e hoʻohiki i ka ʻaina kakahiaka ʻole? ʻO ia ke kilokilo o Teflon. Hānau ʻia mai ka pilina ma waena o ke kalapona a me ka fluorine, ua lanakila nā huahana Teflon i ka honua o nā pale nonstick, hoʻololi i kā mākou lumi kuke a hoʻomaʻemaʻe i ka makani.

Eia naʻe kahi ʻano hoʻololi: ʻo nā hāwanawana o 'PFOA' a i ʻole 'perfluorooctanoic acid' e lana pinepine a puni nā kamaʻilio Teflon. Ua pili ka mōʻaukala i ke kaʻina hana ʻo Teflon, ua piʻi aʻe nā hopohopo i ka wā i hui ai nā mea kuke i uhi ʻia ʻo Teflon me ka wela nui, e hōʻike ana i nā uahi polymer. Mahalo, ua komo ka hana hou. I kēia lā, nui nā huahana Teflon e hoʻohana i ka hōʻailona o ka 'PFOA-noa', e hōʻoia ana i kāu pancakes a me ka maluhia o ka noʻonoʻo i nā lima maikaʻi.

No laila, he aha ka PFOA? ʻO ka PFOA, pōkole no ka waika perfluorooctanoic, he pūhui synthetic i hoʻohana nui ʻia i loko o nā mea kuke nonstick a me nā huahana ʻē aʻe. Ke hoʻomau nei i ke kaiapuni a pili i kekahi mau pilikia olakino, ua hoʻopau nui ʻia kona hoʻohana ʻana e nā mea hana i nā makahiki i hala ma muli o ka noʻonoʻo palekana.

He aha ka PTFE i uhi ʻia?

ʻO Polytetrafluoroethylene (PTFE) he fluoropolymer synthetic o ka tetrafluoroethylene. He plastik hana kiʻekiʻe ia i ʻike ʻia no kāna mau waiwai non-stick, kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa kemika. Hiki ke hoʻopili ʻia ka PTFE i uhi ʻia i kahi ākea o nā huahana, mai nā pans a i nā ʻāpana mīkini, e hāʻawi iā lākou i kahi ʻili maʻemaʻe, non-reactive, a me ka lāʻau ʻole.

Ke hoʻoheheʻe ʻoe i kahi hua mai kāu pā me ka ʻole o ka huhū, ke ʻike nei ʻoe i nā mea kupanaha o PTFE, i ʻike mau ʻia ʻo Teflon coated. ʻO kēia mea kupanaha nonstick, hānau ʻia mai ke kalapona a me ka fluorine, hana i ka mea kuke i moeʻuhane e mālama a maʻalahi hoʻi e hoʻomaʻemaʻe.

Eia naʻe ka manaʻo: ʻo nā huahana Teflon mua i hui pū me 'PFOA', e hoʻohauʻoli ana i ka wā i hui ai kēia mau mea i ka wela nui, e hōʻike ana i nā uahi polymer. ʻO ka wikiwiki a hiki i kēia lā, a nui nā huahana Teflon e haʻaheo i kahi hōʻailona 'PFOA-ʻole', e hōʻoia ana ʻaʻole e hoʻololi kāu kuke ʻana i ka palekana.

He ino anei ka PTFE ia oe?

ʻAʻole inert ka PTFE maʻemaʻe, ma kāna kumu, ʻo PTFE, ka puʻuwai o nā huahana Teflon he nui, ʻaʻole paʻa. ʻO ka paʻa o ke kalapona a me ka fluorine e hōʻoiaʻiʻo i ka nui o ka passive. Eia naʻe, ʻike ʻia kahi hitch me ka wela nui. Ma nā mahana kiʻekiʻe loa (ʻoi aku ma mua o 570 ° F a i ʻole 300 ° C), hiki ke loaʻa i ka uahi polymer, i kekahi manawa e hoʻoulu ai i ka 'polymer fume fever.

ʻO ka hoʻohui ʻana i kahi wrinkle i ka moʻolelo ʻo 'PFOA'. ʻO kekahi ʻāpana o ka moʻolelo Teflon, ua hoʻokiʻekiʻe ʻo ia i nā kuʻemaka ma muli o nā hopohopo olakino i nā wela kiʻekiʻe. ʻO ka nūhou maikaʻi? Haʻaheo nā huahana Teflon o kēia lā i kahi hōʻailona 'PFOA-ʻole'.

I ka pōkole, e like me nā mea hana i loko o ka lumi kuke, ʻo Teflon cookware, ke hoʻohana pono ʻia, hui pū me ka palekana.

He ʻawaʻawa anei ʻo Teflon?

ʻO ka PTFE, me kāna hui pū ʻana o ke kalapona a me ka fluorine, ke kū nei i waho no kona inertness kemika. ʻO ia hoʻi, ma lalo o nā kūlana maʻamau, ua like ia me ka ipu hao kuhiliʻole āu e hoʻohana ai no nā sopa a i ʻole ka ipu hao hao no kāu mau steaks i puhi ʻia. ʻAʻole pili, hoʻokuʻu wale ia i ka ʻai.

Eia nō naʻe, ke hoʻololi ʻia ka moʻolelo i ka wela nui, e ʻāhuehu nā mea. Hiki ke alakaʻi i ka hoʻokuʻu ʻia ʻana o ka uahi polymer ka hoʻokuʻu ʻana i nā mea kuke nonstick i nā wela loa, ma waho aʻe o kona pae i manaʻo ʻia. ʻO kekahi poʻe, i ka wā e ʻike ʻia ai, hiki ke loaʻa i kahi ʻeha pōkole i kapa ʻia ʻo 'polymer fume fever'.

A laila aia ka subplot o 'PFOA'. ʻOiai ua hoʻopili ʻia i ke kaʻina hana o kekahi mau huahana Teflon, nā hopohopo e pili ana i nā hopena olakino i hoʻololi i nā ʻoihana. I kēia lā, ʻālohilohi ke kukui ma luna o nā huahana Teflon he nui i hoʻopaʻa ʻia me ka 'PFOA-free', kahi hōʻike no ka hoʻomohala mau.

No laila, ʻoiai ua hoʻomaʻemaʻe ʻia kā mākou lumi kuke i ka uhi ʻana i ka teflon, hele mai lākou me kahi mantra maʻalahi: mahalo i ko lākou mau palena. Hoʻohana ʻia me ka mālama ʻana, ʻo ka moʻolelo PTFE kekahi o ka pono, ʻaʻole ka mea ʻawaʻawa.

Palekana anei ʻo Teflon?

ʻO ka PTFE, ma kona puʻuwai, he hui o ke kalapona a me ka fluorine. Hāʻawi kēia mea paʻa kemika iā ia i ka inertness maoli, e hoʻolilo iā ia i ka wallflower. E like me kāu ipu hao kuhili ʻole hilinaʻi a i ʻole ka hao hao kahiko, ʻaʻole ia e hui pū; he mea maʻalahi.
Eia nō naʻe, e like me nā mea hoʻokani maikaʻi, ʻo Teflon coated i kāna mau hoʻonohonoho pae makemake. E hoʻoikaika i nā wela kiʻekiʻe, e lele aʻe ma mua o kona wahi hōʻoluʻolu, a e hālāwai paha ʻoe i ka uahi polymer. ʻOiai pōkole, hiki i ka ʻike ke alakaʻi i ka 'polymer fume fever' ʻike ʻole ʻia.

ʻO ka moʻolelo o 'PFOA' i ulana ʻia i ka moʻolelo PTFE, e hoʻāla ana i nā hopohopo olakino. Akā ʻo ka hoʻololi ke kumu o ka hana hou. ʻO nā kukui mākeke o kēia lā me nā huahana Teflon me ka haʻaheo e haʻaheo i nā hōʻailona 'PFOA-free', e hōʻailona ana i kahi kaʻina hana palekana.

I ka hana nui o ka culinary arts, me ka malama pono, PTFE i nonstick coatings e noho hilinaʻi 'ia. Hoʻohiki ia i nā interludes maʻalahi e hoʻomaʻemaʻe a me ka maikaʻi, me ka ʻole o ka hoʻopaʻapaʻa ʻana i ke kukui o ka palekana. Ke hoʻohana pono ʻia, palekana nā huahana PTFE-coated. He mea nui ia:
1. Avoid Overheating: Mai haʻalele i kāu mea kuke i uhi ʻia i ka PTFE ma ka wela nui no ka manawa lōʻihi.
2. E hoʻohana i nā mea ʻoluʻolu: E pale i nā mea metala a i ʻole nā ​​​​mea ʻoi e hiki ke ʻoki a hoʻohaʻahaʻa i ka uhi.
3. Kūʻai mai nā mea hana kaulana: E hōʻoia i ka huahana i hōʻoia ʻia i ka PFOA-free a pili i nā kūlana palekana a me ka maikaʻi.
