Ngaba i-teflon ikhuselekile?

Kwikhitshi laseMelika, i-teflon ye-teflon itshintshe. I-Whosmer yabo encomekayo? Ukanti, iWhissiper ivele: 'Kuthekani nge-PFOAN? Kwaye ubushushu obuphezulu? Ngeentsomi zemisi yePolymere kunye nemibuzo ngokhuseleko, sizifumana sikwi-rossroad. Intsimbi engenalo intsimbi kwaye ikhuphe i-iron ye-iron, kodwa ibali likaTheflon licela ukuxelelwa. Masingene.

Yintoni i-teflon?

I-TEFLon ligama lophawu, laliqhinga inkampani ye-chemouse, kuluhlu lweemveliso ezisekwe kwi-polytetrafliookeoroothylene (PTFE). Ibizwa ngokubanzi ngeepropathi zayo ezingezizo kwaye iba ligama lekhaya lihambelana ne-Cokyoware engalinganiyo kunye nezinye izicelo, ezinjengeempawu, kunye nempahla.

Wake wakhupha le panki ende ethembisa isidlo sakusasa? Ngumlingo we-teflon. Ukuzalwa kwi-bod phakathi kwekhabhoni kunye ne-fluorine, iimveliso ze-TEFLOn zixhase umhlaba we-nontenstring ikhreyithi, ukuguqula ikhitshi lethu kunye nokucoca umoya.

Kodwa nantsi i-pist i-twist: ihlelo le 'PFOAN' okanye 'i-perfluocrooctanoc acid' ihlala ihamba ngeenxa zonke kwiincoko zeThefLon. Imbali inxibelelene nenkqubo yokwenziwa kwemveliso ye-teflon, iinkxalabo ezixhalabisayo xa i-teflon ye-teflon ye-teflon yadibana nobushushu obuphezulu, ukunqunyulwa kwimisi yePolymer enokubakho. Ngombulelo, ubuchule bungene ngaphakathi. Namhlanje, iimveliso ezininzi zeTeflon zinxibe ibheji yokuba 'i-PFOA-Free', iqinisekisa zombini ii-pancake zakho kunye noxolo lwengqondo zisezandleni ezilungileyo.

Ke, ithini i-PFOA? I-PFOAN, ifutshane kwi-PerfluoOcCocCCACCACCACCAOC Acid, yindawo yokuphucula i-Syntheed bake isetyenziswe ngokubanzi kwi-NOTENTAWAX kunye nezinye iimveliso ezahlukeneyo. Qhubeka kwindalo kwaye unxibelelene neenkxalabo zempilo, ukusetyenziswa kwayo kutshekishwe ubukhulu becala ngabavelisi kule minyaka idlulileyo ngenxa yokuqatshelwa kokhuseleko.

Yintoni iPtfeed?

I-Polytetrafluoroothyyyyyyyyyyyyyeyyen (PTFE) yi-FlooroOlly yeTetofluothyleothylene. Yiplastiki yokusebenza ephezulu eyaziwa ngokuba ziipropathi zayo ezingezizo ezonzanga, ukumelana nobushushu obuphezulu, kunye nokuxhathisa imichiza. I-ptfe idityaniswe kuluhlu olubanzi lweemveliso, ukusuka kwiipani kumatshini womatshini, ukubanika umntu ogudileyo, ongafundanga, kwaye ongasebenziyo.

Xa uqhuba iqanda kwipaneli yakho nge-iro fuss, ufumana imimangaliso ye-PTFE, ehlala yaziwa njenge THFLOT. Oku kungamangalelwanga, ukuzalwa kwikhabhoni kunye ne-fluorine, yenza ukuba iphupha liphupha lokucoca kwaye kulula ukucoca.

Kodwa nantsi i-tidbit: Iimveliso ze-teflon zakuqala nje nge-'PFOAN Khawuleza uye namhlanje, kwaye uninzi lweemveliso ze-teflon ziqhayisa 'i-BFAAN-Free' Ibheji, eqinisekisa ukuba ukupheka kwakho okungagungqi akunakalise ukhuseleko.

Ngaba i-ptfese embi?

I-ptfe inyulu yi-Inert, kwi-core yayo, i-PTFE, intliziyo yeemveliso ezininzi ze-teflon, ihlala ingasebenzi. Ibhondi yayo yekharbon kunye ne-fluorine iqinisekisa ukuba iyadlula. Nangona kunjalo, i-hitch ibonakala ngobushushu obuphezulu. Ngamaqondo obushushu aphezulu kakhulu (ngokuqhelekileyo ngaphezulu kwe-570 ° F okanye i-300 ° C), ukubakho i-Polymer mpumus, ngamanye amaxesha ibangela 'i-fevermer fure'.I-feedmer feed.

Ukongeza i-Wrinkle kwiThale yi 'PFOAN'. Nje ukuba inxenye yengxelo ye-TFFLon, iphakanyiselwe amashiya ngenxa yenkxalabo yezempilo kumaqondo obushushu aphezulu. Iindaba Ezilungileyo? I-Teflon yeTeflon ye-Teflon ngokuzingca ibhekisa 'i-pifo-asile.

Kwi-zungelo, njengaso nasiphi na isixhobo ekhitshini, i-teflon cookiwa, xa isetyenziswe ilungile, ihlanganisene ngokulula ngokhuseleko.

Ngaba i-teflon iyityhefu?

I-PTFE, ngokudityaniswa kwayo okhethekileyo kwikhabhoni kunye ne-fluorine, imele i-intertures yayo yekhemikhali. Oku kuthetha ukuba, phantsi kweemeko eziqhelekileyo, kuya kuphela njengembiza yentsimbi engenanto onokuyisebenzisa kwiisuphu okanye i-the yentsimbi yentsimbi yentsimbi yentsimbi yakho. Ayisebenzi, ivumela nje ukutya.

Nangona kunjalo, xa ibali lishiyiwe phezulu, izinto zifumana i-tad stemy. Ukutyhala i-notstway Cholowawa kwiqondo lobushushu eligqithisileyo, ngaphaya koluhlu lwayo olucetyiswayo, lunokukhokelela ekukhutshelwe umsi wePolymer. Abanye abantu, xa batyhilwe, banokuziva benengxaki yokufutshane eyaziwa ngokuba 'yi-polymer fume yesiteti'.

Ke kukho i-subplop ye 'PFOA'. Ngelixa sele unxibelelene nenkqubo yokwenziwa kweemveliso ze-teflon, inkxalabo malunga neziphumo zempilo ezenziwe nge-pivoot yeshishini. Namhlanje, ibala likhanya ngokuqaqambileyo kwiimveliso ezininzi ze-teflon zisitampu 'nge-'PFA-Free', iTestamente ivela kwindaleko yokuqhubeka kwendalo.

Ke, ngelixa i-teflon iqengqele yenze ikhitshi yethu icocekile ngokulula, zeza ne-mantra elula: hlonipha imida yabo. Iphathwe ngononophelo, i-PTFE's Tale yenye yempahla, hayi ityhefu.

Ngaba i-teflon ikhuselekile?

I-Ptfe, entliziyweni yayo, kukungcungcutheka kwekhabhoni kunye ne-fluorine. Olu luhlu lweekhemikhali luzibazisela ilungu lendalo, lenza lo downlower. Kanye njengembiza yentsimbi engathandekiyo okanye i-iron-endala ye-iron, ayizihlanganisi; Iqhuba ngokulula.
Nangona kunjalo, njengayo nayiphi na i-periolymer elungileyo, i-teflon yayiqengqeleka ineesetingi zawo ezikhethiweyo. Ukungena kubushushu obuphezulu, ukubonda ngaphaya kwendawo yalo yokuthuthuzela, kwaye ungadibana nomsi wePolymer. Ngelixa elifutshane, ukuveza kunokukhokelela kunqabile ukuba ichaphazele 'i-polymer firmer'.

Ibali 'le-PFOA' likhe lifungwe kwi-PTFE TALE, inkxalabo yezempilo. Kodwa utshintsho luyinto ebalulekileyo. Iibhulorho zentengiso zanamhlanje ezinemifanekiso ye-teflon enekratshi futtor 'iqhayisa' le-PFOAN-Free '

Kwintsebenzo eMnandi yobugcisa beCuliutha, kunye nononophelo olufanelekileyo, i-ptfe kwi-nonrick coatings ihlala ililungu elinethemba lokuphosa. Ithembisa imibutho ecociweyo ecocekileyo kunye nokusebenza kakuhle, ngaphandle kokuphawula indawo yokhuseleko. Kubalulekile ukuba:
1.avoid ukugqithisa kakhulu: Ungaze ushiye i-pheeware yakho edibeneyo kubushushu obuphezulu ixesha elide.
2.Ukuhlala iisoftware: Ziphephe izinto zensimbi okanye izinto ezibukhali ezinokukrola kwaye zikhuphe ukuthuka.
3.Purchaase kubavelisi abadumileyo: Qinisekisa ukuba imveliso iqinisekisiwe i-PFOA-ESIFANELEKILEYO kwaye inamathela kwiindawo zokhuseleko nezemigangatho esemgangathweni.
