Teflon yakachengeteka sei mumachira?

Sevatengi, isu tinogara tichitsvaga zvigadzirwa zvinovandudza hupenyu hwedu hupenyu. Imwe yekuvandudza iri kushandisa teflon mumachira, inopembererwa nekuda kwezvivakwa zvehunhu zvakashata uye zvinoshandiswa semuridzi wechidimbu. Nekudaro, mubvunzo unowanzo amuka: ''Yakachengeteka sei mumachira? ' Ngationgororei iyi musoro wenyaya.

Pasi pedenga reSkyland, vadzokere vedenga, vanokwira, uye vashandi vemauto zvakafanana vakavimba negamba rakavanzika kuti vadzivirirwe nezvinhu: jira rePTFF. Ichi chinoshamisa chimbichimbi, chakapembedzwa nemvura isingafungidzirwe, nekudzivira, uye kuramba madhiri, mafuta, uye makemikari anodzivirira vasingaverengeki kubva mumatare akaomarara.

Nekudaro, hazvisi zvese izvo zvinopenya ndarama. Muna 2019, zvinyorwa zvemvura ' Kusava nechokwadi uye kunetseka kwakakuvadzwa neruzhinji, vazhinji vavo vakatanga kukohwa kuchengetedzwa kwenguo dzinogadzirwa kubva pane izvi. Iyo International Carcinogen Agency yakazotaurwa PTFE sekirasi 2B Carcinogen, chikamu chinozevezera chenjodzi dzinogona kunge dzinofamba-famba.

Nhasi, isu tinotanga kuda kwedu: kuti tifumure chokwadi kuseri kweiyo Teflon's Shimmering Fade uye kuona, kamwe uye kune vese, kana ichi muchengeti wekunze wakachengeteka seyakaitwa nenhero yayo.

Teflon: Nhanganyaya

Teflon izita remhando yerudzi rwePolymer inozivikanwa sePolytetraFluorohylene (PTFF). Icho chinhu chinowanzozivikanwa nekushandiswa kwayo mukunyepedzera pani, uye muindasitiri yercelile, Teflon inoshandiswa zvakanyanya kugadzira mvura yemvura uye isina simba.

Mune lab kuSupont muUnited States, 1938, Dr. Roy Plunkett yakagumburwa pane chimwe chinhu chisingatarisirwi. Chakawira chaive chinhu chakanaka chakachena, chakazotumidzwa zita rekuti Teflon. Iyi teflon inovhara, inodaidzwa kuti Polytetrafluoroetherylene (PTFE), yaitaridzika isingafarire. Asi kutaridzika kunogona kunyengera.

PolytetraFluorootherylene ptfe, mune kwayo, inozvirumbidza chimiro chakasarudzika. Polymer yayo ine kabhoni uye fluorine, zvichikonzera mumakemikiki anoshamisa eremical inertia. Zvichitaurwa zviri nyore, izvi zvinoreva kuti hazvisanganisi nemakemikari akaora. Pane kudaro, inomira yakasimba, ichiramba kuita kana corrode.

Mumwe anogona kubvunza, 'Nei ichi chichiita? ' Heino kwainovhenekera. Munyika izere nezvigadzirwa zvinodudzira, tsvimbo, kana chisungo, teflon inoramba isingafarire. Iyi isina-tsvimbo hunhu, yakasanganiswa neiyo imwe yeiyo yakaderera coefficients yekukakavara, inoita kuti ive yakakodzera kubheya coated. Saka, kana iwe uchifema mazai edzangu aya, anotsvedza zvisina basa kubva pani.

Asi, meroni aTeflon haangobatanidzwe kukicheni. Kupiwa kwayo yakakwira kupisa kupokana, maindasitiri kuyambuka rakawanda renji kunoratidza iyo kune yakanyanya kupisa ekushisa. Kutaura zvazviri, kupokana kwayo kwekushora kunoita kuti idavirire pakuchengeta mamwe emakemikari ane hutsinye.

Uyezve, kana iwe uchibata tete sosi, inonzwa inotsvedza, nekuda kwechimiro chayo chakanaka. Mumaseti emagetsi, zvivakwa zvayo zvekushandisa zvinokosheswa, zvichidzivirira matunhu nemidziyo kubva kune zvemagetsi zvemagetsi zvemagetsi.

Nekudaro, mari yese ine mativi maviri. Paunenge waiswa pasi pekupisa kwakanyanya, PTFE coated cookware inogona EMIT Polymer mafuru. Hazvishamisi, asi mafuro aya anogona kutungamira ku 'polymer fume fever ' muvanhu, mamiriro anoyeuchidza nezvefuru. Shamwari dzedu dzine simba, shiri dzemapuru, dzinogona kuve dzakanyanya kungwarira panhonga idzi polymer.

Munguva yekugadzira kwayo, imwe mumvuri looms: kushandiswa kwePerfluorooCoOCAIC (PFOA). Yakabatanidzwa neine hutano hwehutano, kupokana pamusoro pekuchengetedza kwaro kwakanyanyisa. Kuteerera izvi kunetseka, vagadziri muUnited States vakasarudza chikamu kunze kwePfoa kubva pakuita.

Mukupedzisa, TEFLon's Tile ndiyo imwe yeunyanzvi uye kushandurwa. Kubva pakuwanikwa kwaro netsaona pakushandiswa kwayo kwakapararira, rwendo rwayo runopedza zvese zvinogona uye zvingangoitika zvemazuva ano. Kufanana nezvinhu zvese, kunyange zvichingopa zvikomborero zvikuru, zviri kwatiri kuti tishandise nekuchenjera.

Kuongorora Kuchengetedza: Kunzwisisa PFOA

Kwemakore, kuchengetedzeka kweTeflon kwave kuri musoro unopisa musoro. Chinhu chikuru chekunetseka chaisave pamusoro peTeflon (ptfe) pachayo asi nezve compound inoshandiswa mukugadzirwa kwayo inonzi Perfluoroocanoic Acid (PFOA). Chinhu ichi chakabatanidzwa nenyaya dzakasiyana siyana hutano, zvichikonzera kufungisisa pakati pevatengi. Nekudaro, zvakakosha kuti uzive kuti sa 2013, nekuda kwehutano hwehutano uye hwezvakatipoteredza, vagadziri vezvakatarisana, vagadziri vepamusoro vakatanga kushandiswa pfoa mukugadzirwa kweTeflon.

Teflon mumachira nhasi

TEFLON yanhasi inoshandiswa mumachira inonyanya kufungwa yakachengeteka, sezvo ichisisina pfoa. Iyo teflon yekuvharira rubato rakabiridzira, kubatsira zvinhu zvinodzivisa mastaa uye kuendesa huwandu hwechigadzirwa hurefu. Icho chinhu chinonyanya kufarirwa negiya rekunze, Upholstery, uye zvimwe zvinhu zvinopfekedza nekubvarura.

Pane njodzi here?

Pasinei nokutendeuka kure nePfoa, zvimwe zvinonetsa zvekuchengetedza nezvechengetedzo yeTheflon mumachira. Dambudziko guru rinomuka apo zvinyorwa zvacho zvichinge zvapedzwa zvakanyanya kupisa kwakanyanya Nekudaro, pasi pezvakajairika mamiriro ekushandisa, maFabics akaumbwa neTeflon haasvike izvi tembiricha, achiita kuti njodzi isipo mukushandiswa kwemazuva ese.

Maonero Akaringana

Teflon inoshandiswa mumachira kazhinji yakachengeteka pakushandiswa kwemazuva ese. Iyo inopa mizhinji mizhinji, kusanganisira yepaiti kuramba uye yakawedzera mucheka zvizere. Nekudaro, semidziyo yese, kunzwisisa zvavakaita uye kushandiswa kwakaringana kunokosha kuti uve nechokwadi chekuchengetedza. Zvinoshungurudza zvakamutswa munguva yakapfuura zvakatungamira kuchinja kwakakosha kwekugadzira, kugadzira teflon yatinoshandisa kuve kwakachengeteka kupfuura nakare kose.

Rangarira, kuramba uchiziviswa nezvezvigadzirwa zvatinoshandisa zuva rega rega idanho rakakosha mukuve vanoziva vatengi. Sezvo isu tichiramba tichizvikoshesa zvinosimudzira hupenyu hwedu, tinofanirawo kuturikira uye kuchengeteka mune zvese zvikamu zvekugadzira uye kushandiswa.
