Ni teflon umutekano?

Mu gikoni cy'Abanyamerika, Teflon yatwikiriye pans. Amatungo yabo yoroshye-meza? Nyamara, yongorerana avuka: 'Bite se kuri PFOA? N'ikirere kinini? Hamwe n'imigani ya polymer impfabupfura nibibazo kumutekano, twisanga mumuhanda. Icyuma kitagira ikinanga kandi bigatwara ibyuma, ariko inkuru ya Teflon irabibwira. Reka twihishe.

Teflon ni iki?

Teflon nizina ryikirango, bwaringaniye muri sosiyete ya chemours, kubicuruzwa bitandukanye bishingiye cyane cyane cyane kuri polytetrafürouorouoRylene (PTFE). Birazwi cyane kubintu bidafite inkoni kandi byahindutse izina ryurugo bidasobanutse hamwe nibikoresho bidafite inkoni hamwe nibindi bikorwa bitandukanye, nka kabili, kashe, ndetse n'imyambaro.

Wigeze ukuramo iryo furo nziza isezeranya kuba ifunguro rya mu gitondo? Ubwo ni amarozi ya Teflon. Yavutse ku nkunga hagati ya karubone na fluorine, ibicuruzwa bya Teflon yahanze isi aho bikora, bihindura igikoni cyacu no gukora isuku.

Ariko dore umugambi wo kugoreka: Yongorera kwa 'PFOA' cyangwa 'acide parfrooctanoic' akenshi ireremba ibiganiro bya Teflon. Amateka afitanye isano ninzego za Teflon ya Teflon ya Teflon ya TEFLON hejuru mugihe teflon yandikaga yahuye nubushyuhe bwinshi, hirya no hino bishobora guhimba. Igishimishije, guhanga udushya twinjiye. Uyu munsi, ibicuruzwa byinshi bya teflon byambaza ikirango cyo kuba 'PFOA-KUBUNTU', kwemeza ko pancake yawe n'amahoro yo mumutima byombi biri mumaboko meza.

Noneho, PFOA ni iki? PFOA, ngufi kuri aside Perfluoctano Gukomeza ibidukikije kandi bifitanye isano n'ibibazo byinshi byubuzima, ikoreshwa ryarwo ryagiye ryihuta nabakora mumyaka yashize kubera ibitekerezo byumutekano.

Ni iki PTFE ihatirwa?

PolytetrafrouoRoathylene (PTFE) ni fluoropolemmer ya tetrafluoroathylene. Nibice byinshi bizwi kumenyekanisha kumiterere idashidikanishi, kurwanya ubushyuhe bwinshi, no kurwanya imiti. PTFE irashobora gukoreshwa kubicuruzwa byinshi, uhereye kumasaro kubice byimashini, kubaha uburyo bworoshye, butagenda neza, kandi budahanitse.

Iyo uzengurutse amagi yawe hamwe na zeru zeru, uhura nibitangaza bya PTFER, mubisanzwe bizwi nka Teflon yambaye. Iyi ngingo itukana, yavutse kuri karubone na fluorine, ikora guteka inzozi gukora kandi byoroshye gusukura.

Ariko dore tidbit: Ibicuruzwa bya Teflon kare byambere byakurikiranye na 'PFOA', bigatera imbaraga mugihe ibi bintu byujuje ubushyuhe bwinshi, bigatuma habaho ubushyuhe bwinshi. Byihuse kugeza uyu munsi, hamwe nibicuruzwa byinshi bya Teflon biteatad adge 'pfoa-' ubusa ', kwemeza ko guteka ko kudakora nabi bidahuye numutekano.

Ese PTFI NIBI kuri wewe?

PTFER PTF ni inert, yibanze, PTFE, umutima wibicuruzwa byinshi bya teflon, biracyari byo mubyoroshye. Umubano wacyo wa karubone na fluorine byemeza ko ahanini. Ariko, hitch igaragara nubushyuhe bwinshi. Mugihe cyuburebure bukabije (mubisanzwe hejuru ya 570 ° F cyangwa 300 ° C), rimwe na rimwe bitera 'ibiranga polymer.

Ongeraho imyumbati kumugani ni 'pfoa'. Igihe kimaze kuvuga inkuru ya Teflon, yazamuye ijisho kubera ibibazo byubuzima ku bushyuhe bwo hejuru. Ubutumwa bwiza? Ibicuruzwa bya teflon byuyu munsi biboneye kashe ya 'PFOA-Free'.

Muri make, nkibikoresho byose mugikoni, teflon guteka, mugihe ukoreshwa neza, kuvanga byoroshye umutekano.

Uburozi bwa Teflon?

PTFE, hamwe nu ruvange rwihariye rwa karubone na fluorine, zigaragara kubitunganijwe bya shimi. Ibi bivuze, mubihe bisanzwe, ni pasiporo nkinyano yicyuma runaka ushobora gukoresha kumasupu cyangwa umuhanga wicyuma kuri stewak yawe yambaye ubusa. Ntabwo ikorana, itukura gusa ibiryo.

Ariko, iyo inkuru ivuga ubushyuhe bwinshi, ibintu bibona tad steamy. Gusunika ubusa Gutora Ubushyuhe bukabije, birenze urugero byafashwe, bishobora gutuma hasohora imyotsi ya polymer. Bantu bamwe, mugihe bashyizwe ahagaragara, bashobora guhura nazo igihe gito kizwi nka 'Polymer kuramya umuriro'.

Noneho hari subplot ya 'PFOA'. Mugihe bimaze guhuzwa nuburyo bwo gukora bwibicuruzwa bimwe na bimwe bya teflon, impungenge zijyanye ningaruka zubuzima zakozwe inganda pivot. Uyu munsi, imvugo irabagirana cyane ku bicuruzwa byinshi bya teflon byashyizweho kashe hamwe na 'pfoa-ubusa', Isezerano kugirango Isezerano rihoraho.

Noneho, mugihe Teflon yapakiye igikoni cyacu cyoroshye-kwisukura ingendo, bazanye na mantra yoroshye: kubaha imipaka. Yakenywe no kwitaho, umugani wa PTF ni kimwe mubyihangana, ntabwo ari uburozi.

Ni teflon umutekano?

PTF, kumutima wacyo, ni ukuvuga ka karubone na fluorine. Iyi mpano zimiti ni indorerezi karemano, ikayikora rwose urukuta. Nka nkinkono yawe yizewe cyangwa imyaka-ishaje yateye, ntabwo ivanze; byorohereza gusa.
Ariko, kimwe numukora neza, teflon yapakiwe ifite imiterere yicyiciro cyatoranijwe. Venture mu bushyuhe bwo hejuru, byakurenze akarere kayo keza, kandi ushobora guhura n'umwotsi wa polymer. Mugihe gito, kwerekana bishobora kuganisha ku gake cyane 'Polymer fum Hover'.

Inkuru ya 'PFOA' amaze kuboha inka ya PTFE, izamuka ku buzima. Ariko guhindura ni ishingiro ryo guhanga udushya. Ibiti byisoko ryuyu munsi hamwe nibicuruzwa bya Teflon byerekana neza badge 'pfoa-yubusa', byerekana inzira yo gukora neza.

Mu mikorere ikomeye yubuhanzi bwo guteka, hamwe nubwitonzi bukwiye, PTFE mubintu bidakwiye bikomeza kuba umunyamuryango wizerwa. Irasezeranya byoroshye-guhumura neza no gukora neza, nta guhungabanya umutekano .Iyo yakoresheje neza, ibicuruzwa bya PTFete bifite umutekano. Ni ngombwa kuri:
1.Ibanga cyane: Ntuzigere usiga PTFE wanditse kuri PTFE-ftfe yice hejuru yubushyuhe bwinshi mugihe kirekire.
2.se ibikoresho byoroheje: Irinde ibintu cyangwa ibintu bikarishye bishobora gushushanya no gutesha agaciro.
3.Purchase kuva kubakora bizwi: Menya neza ko ibicuruzwa byemewe PFOA-kubuntu kandi byubahiriza umutekano nubuziranenge.
