Imyenda ya Teflon ifite umutekano?

Nkabaguzi, duhora dushakisha ibicuruzwa binoza ubuzima bwiza. Imwe mu nshyanga ikoresha Teflon mumyenda, yizihijwe kubintu byayo birwanya kandi bikoreshwa nkumurinzi wimyenda. Ariko, ikibazo gikunze kuvuka: 'Teflon ifite umutekano mu mwenda? ' Reka dusuzume iyi ngingo mubwimbitse.

Munsi y'ikirere, abakandaga, abakanguzi, abazamuka, n'abasirikare kimwe bishingikirije ku ntwari zihishe kugira ngo bakingire ibintu: umwenda. Iyi samnic yibasiwe, yizihizwaga kubera amazi yacyo adashira, no kurwanya indabyo, amavuta, n'imiti, yakijije bucece abadiventiste batabarika baturutse mu materaniro akaba no kwizirika.

Ariko, ntabwo aribyo byose birabagirana ni zahabu. Muri 2019, documentaire yiswe 'Amazi yumukara ' ashushanyije iyi ntwari mu buryo bundi buryo, akaga kagaragara ko akaga gashobora kwigomeka munsi y'urugo rwayo. Gushidikanya n'impungenge zuzuye abaturage, benshi muri bo muri bo bakaba batangiye kwibaza umutekano w'imyenda yatanzwe muri ibi bikoresho. Ikigo mpuzamahanga cya karcinogen nyuma yaho nyuma ya PTFE nka 2b Carcinogen 2b, icyiciro cyongorera ibishobora guhungabana ariko ntibisanirwe neza.

Uyu munsi, dutangiye gushaka ibyacu bwite: Kugira ngo tumenye ukuri kwari inyuma ya Teflon kandi tumenye, rimwe na rimwe, niba umurinzi wo hanze ukomeye ufite umutekano nkuko umurage wacyo.

Teflon: Intangiriro

Teflon nizina ryikirango ubwoko bwa polymer izwi nka poltetrafrouoRyleneforeilene (PTFE). Nibintu bikunze gushimishwa kubishyira mu bikorwa mu gihe cy'amasafuriya, no mu nganda z'ibintu, TEFLON ikoreshwa cyane kugira ngo amazi ahindure amazi no kurwanya Stain.

Muri laboratoire kuri Dupoont muri Amerika, 1938, Dr. Roy Pluntket yatsitaye ku kintu gitunguranye. Icyagaragaye cyari ibintu byiza by'ifu, nyuma byise Teflon. Iyi shitingi ya teflon, yitwa kumugaragaro PolytetrafrouorouoRylene (PTFE), yasaga neza. Ariko ibigaragara birashobora kubeshya.

Polytetrafrouoroethylene PTFE, muburyo bwabwo, yirata imiterere yihariye. Polymer yayo igizwe na karubone na fluorine, bikaviramo inturti yimiti itagereranywa. Muri make, ibi bivuze ko itavanga neza hamwe n'imiti ikongerera. Ahubwo, ihagaze neza, yanze kubyitwaramo cyangwa kongero.

Umuntu arashobora kubaza, 'Kuki icyo kibazo? ' Dore aho imurika. Mw'isi yuzuyemo ibikoresho bifatika, inkoni, cyangwa bond, Teflon ikomeje kutitaho ibintu. Iyi mico idashidika, ihujwe numwe mumyanyateri yo hasi yo guterana amagambo, bituma bituma ari byiza kubishusho. Noneho, iyo uzengurutse ayo magi ya mugitondo, banyerera bidafite imbaraga.

Nyamara, ibyiza bya Teflon ntabwo bigarukira mu gikoni. Urebye ubushyuhe bwinshi, inganda zugurumana imibare yagutse kubikoresha kugirango ibyifuzo byikirere kinini. Mubyukuri, kurwanya ruswa bituma ukunda kubika zimwe mumiti ikaze cyane.

Byongeye kandi, iyo ukoze hejuru ya teflon, numva kunyerera, bitewe nuburyo bwiza. Mu mikorere y'amashanyarazi, imitungo yayo yo kwigarurira ifite agaciro, irinda imizunguruko n'ibikoresho ku mashanyarazi adashaka.

Ariko, igiceri cyose gifite impande ebyiri. Iyo bakorewe ubushyuhe bwinshi, PTFE Cookware irashobora gusohora insinga. Ntibisanzwe, ariko iyo mvumu irashobora kuganisha kuri 'felmer imyisanzure ' mubantu, ikintu cyibutsa ibicurane. Inshuti zacu zibabaye, inyoni zinyamanswa, zirashobora kumva cyane aya mafe ya polymer.

Mugihe cyayo cyo gukora, ikindi gicucu gihurira: Gukoresha aside Perfrooctano (PFOA). Bafitanye isano n'impungenge z'igihe kirekire, kujya impaka ku mutekano wacyo. Kumvira ayo maganya, abakora muri Amerika bahisemo kwikinisha PFOA kuva.

Mu gusoza, imigani ya Teflon ni imwe mu guhanga udushya no guhuza n'imihindagurikire. Kuva muvumburwa kubwimpanuka kubikoreshwa cyane, urugendo rwarwo rushimangira ubushobozi n'imitego y'ibikoresho bigezweho. Kimwe nibintu byose, mugihe bitanga inyungu nyinshi, bireba kugirango tuyikoreshe neza.

Gusuzuma umutekano: gusobanukirwa pfoa

Kumyaka, umutekano wa Teflon wabaye ingingo ihanitse ishyushye. Impungenge zibanze nticyari kuri Teflon yonyine ariko kubyerekeye compond ikoreshwa mubikorwa byayo byitwa acide ya parfluoctano (PFOA). Ibi bintu byahujwe nibibazo bitandukanye byubuzima, bigatuma habaho impungenge mubaguzi. Ariko, ni ngombwa kumenya ko guhera kwa 2013, kubera ibibazo byubuzima nibidukikije, abakora ibyingenzi bishimira ikoreshwa rya PFOA mumusaruro wa Teflon.

Teflon mumyenda uyumunsi

Uyu munsi Teflon yakoreshejwe mumyenda ahanini ifatwa nkumutekano, kuko itagifite pfoa. Inyigisho za Teflon ni umwenda wimyenda, ufasha ibikoresho birwanya ikizinga no kwagura ibicuruzwa. Nibintu byashimwe cyane mubikoresho byo hanze, upholsters, nibindi bintu bigomba kwambara no gutanyagura.

Hoba hariho ingaruka?

Nubwo yavuye muri PFOA, bimwe bireba urumuri kubyerekeye umutekano wa Teflon mumyenda. Ikibazo nyamukuru kivuka mugihe ibikoresho bishyushye cyane (hejuru ya 600 ° F / 316 ° F), umwanya ushobora kurekura iyo uhumeka. Ariko, mubihe bisanzwe byo gukoresha, imyenda yatwikiriye Teflon ntabwo igera kuri ubu bushyuhe, bigakora ibyago hafi ya buri munsi.

Icyerekezo kiringaniye

Teflon ikoreshwa mumyenda muri rusange ni umutekano wo gukoresha burimunsi. Itanga inyungu nyinshi, harimo no kurwanya ikirata no kongera ubusambanyi. Ariko, kimwe nibikoresho byose, gusobanukirwa imitungo yabo no gukoresha neza ni ngombwa kugirango umutekano wungabunga umutekano. Impungenge zavuzwe kera zatumye habaho impinduka zikoreshwa, bigatuma Teflon Dukoresha uyumunsi ari nziza kuruta mbere hose.

Wibuke, gukomeza kumenyeshwa ibicuruzwa dukoresha burimunsi nintambwe yibanze yo kuba abaguzi bamenyekana. Mugihe dukomeje guha agaciro udushya twiyongeraho, tugomba no kumpanga mu mucyo n'umutekano mubice byose byumusaruro no gukoresha.
