Ikhuselekile kangakanani i-teflon kwiilaphu?

Njengabathengi, sihlala sikhangela iimveliso eziphucula ubomi bethu. Enye inzako enjalo isebenzisa i-teflon kwilaphu, ibhiyozelwe iipropathi zayo ezingahambelaniyo kwaye isetyenziswe njengomkhuseli welaphu. Nangona kunjalo, umbuzo uhlala uvela: 'Yiphi i-teflon kwiilaphu? ' Masihlole le ngcaciso ubunzulu.

Ngaphantsi kwesibhakabhaka esichithakeleyo, i-backpackers, iimbembeli, kunye nabasebenzi basemkhosini ngokufanayo baxhomekeke kwiqhawe elifihliweyo ukuze bakhuseleke kwizinto: Ilaphu le-Ptfe. Le fatrikit ye-fatriki, ibhiyozelwe ukungqubana kwamanzi okungafakwanga, ukuphefumla, kunye nokuxhathisa amabala, ioyile, kunye neekhemikhali, ikhuselekile ethe cwaka.

Nangona kunjalo, ayizizo zonke ezo glitters yigolide. Ngo-2019, uxwebhu olunesiphiwo 'Amanzi amnyama ' apeyinti eligorha ngendlela engakhathaliyo, enokutyhafa iingozi ezinokubakho phantsi kwe-sheen yokukhusela. Amathandabuzo kunye neenkxalabo ezikhukulisekileyo esidlangalaleni, uninzi lwazo luqalisa ukuthandabuza ukhuseleko lweengubo zezambatho zenziwe kwezi zinto. Iarhente ye-carcinogen ye-carcinogeni yeHlabathi kamva icwangcisiwe i-PTFE njengeklasi ye-2b ye-2b carcinogen, udidi oluhlebeza umngcipheko onokubakho kodwa lungangqinelani.

Namhlanje, siqalisa ukufuna kwethu: ukutyhila iinyaniso ezingemva kwe-teflon's afikelela kwaye ukufumanisa, kube kanye, ukuba lo mgadi wabangaphezulu bakhuselekile njengamabango ayo okukhuselekileyo.

I-TFLO: INTSHAYELELO

I-teflon ligama lohlobo lohlobo lwe-polymer eyaziwa ngokuba yiPolytetraflum (Ptfe). Yinto ebonakalayo ebonakalayo kwisicelo sayo kwii-phans ze-nonseir, nakwimizi-mveliso ye-Tect, i-TEFLon isetyenziselwa ukwenza amanzi amalaphu kunye nokunganyangeki kwamanzi.

Kwilebhu kwi-DUPOnt e-United States, ngo-1938, uGqr. Roy Plungoket wakhubeka kwinto engalindelekanga. Into eyavelayo yayiyinto ehle kakhulu, kamva ebizwa nge-teflon. Le teflon yokuhamba, ibizwa ngokuba yiPolytetrafluoroothylene (PTFE), ijongeka ngaphandle. Kodwa ukubonakala kunokukhohlisa.

I-Polytetrafluororoothyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyenylene ptfe, kubunyani bayo, eziqukethe isakhiwo esikhethekileyo. I-polymer yayo iqulethe ikhabhoni kunye ne-fluorine, ekhokelela kwi-Interia yayo ebalaseleyo. Ngamafutshane, oku kuthetha ukuba ayixubeki kakuhle ngeekhemikhali. Endaweni yoko, imele iqinile, iyala ukuphendula okanye ikhuphe.

Umntu unokubuza, 'Kutheni le nto? ' Nantso apho kukhanya khona. Kwilizwe elizaliswe zizixhobo ezinamathela, unamathela, okanye ibhondi, i-teflon ihlala ingakhathali. Lo mlinganiswa unganamathela, udityaniswe nenye yezona zixhobo ziphantsi kwengxabano, zenza ukuba ilungele ukhuseleko olwamkelweyo. Ke, xa ufeza amaqanda ekuseni, batyibilika ngaphandle kwepani.

Ukanti, ukufaneleka kukaTeflon akufanelanga nje ekhitshini. Ngenxa yokumelana nobushushu bayo, amashishini oluncomelo olubanzi lusebenzisa usetyenziso lweqondo lobushushu obuphezulu. Ngapha koko, ukuxhathisa i-corosion yayo kwenza ukuba ithande enye yezona zikhenkceze zonakeleyo.

Ngapha koko, xa uchukumisa umphezulu we-teflon, uziva ngathi uyatwilika, ngenxa yesakhiwo sayo esihle. Kwiseti yombane, iipropathi zayo zokufaka i-subsang zixabisekile, zisekekethe ezikhusela kunye nezixhobo ezivela ekuhambeni kombane okungafunekiyo.

Nangona kunjalo, yonke ingqekembe inamacala amabini. Xa uphantsi kobushushu obuphezulu kakhulu, i-ptfeated cookiwa ye-ptware inokubangela i-polymer fumes. Inqabile, kodwa le susi inokukhokelela kwi presemer 'ebantwini, imeko ikhumbula umkhuhlane. Abahlobo bethu abanamaphiko, iintaka zeZilwanyana zeZilwanyana, zinokuthathela ingqalelo ngakumbi kule mpumuko yePolymer.

Ngexesha lokwenziwa kwayo kwemveliso, elinye i-SHIFOD LOUSOMW Inxulunyaniswa neenkxalabo zexesha elide, impikiswano malunga nokhuseleko lwayo yaqaqambisa. Ukuthobela ezi zinto zixhalabisayo, abavelisi eUnited States bagqiba kwelokuba bakhuphe i-PFOA kule nkqubo.

Ukuqukumbela, i-Teflon's Tale yenye yezinto ezintsha kunye nokuzimela. Ukusuka kwi-Fency yayo ngengozi kusetyenziso lwayo ngokubanzi, uhambo lwayo luphawulela okunokubakho kunye nemigibe yezinto zanamhlanje. Njengazo zonke izinto, ngelixa inika izibonelelo ezinkulu, kuse kuthi ukuba siyisebenzise ngobulumko.

Ukuvavanya ukhuseleko: Ukuqonda i-PFOA

Iminyaka, ukhuseleko lwe-TEFLon lusisihloko esishushu. Inkxalabo ephambili yayingeyonto malunga ne-teflon (PTFE) ngokwayo kodwa malunga necandelo elisetyenzisiweyo kwimveliso yalo ebizwa ngokuba yi-perfluoccanoc acid (PFOA). Le nto idityaniswe nemicimbi eyahlukeneyo yezempilo, ebangela ukuba ikhathazeki phakathi kwabathengi. Nangona kunjalo, kubalulekile ukuba uqaphele ukuba ngo-2013, ngenxa yenkxalabo yezempilo kunye nezendalo, abavelisi abaphambili bezingisa ukusetyenziswa kwe-PFOL kwimveliso ye-teflon.

I-TEFLOn kwiilaphu namhlanje

I-teflon yanamhlanje isetyenziswe kwiilaphu ikakhulu ithathwa ngokukhuselekileyo, kuba ayisenayo i-PFOAN. I-teflon yokuhlekisa ngumkhuseli we-teflon ngumkhuseli we-tiflon fast, ukunceda ngezixhobo zokuxhathisa amabala kwaye asuse ubomi obude bemveliso. Yinto exabiseke kakhulu kwigiya yangaphandle, i-ihholstery, kunye nezinye izinto zithambisa ukunxiba kunye nokukrazula.

Ngaba ikhona imingcipheko?

Ngaphandle kokutshintsha kwe-ppfoa, ezinye zixhalabisa i-linger malunga nokhuseleko lwe-teflon kwiilaphu. Eyona ngxaki iphambili iphakama xa le nto ifudumele amaqondo obushushu aphezulu (ngaphezulu kwe-600 ° F / 316 ° C), malunga nenqaku elinokuthi likhulule ingozi ukuba ifakwe kuyo. Nangona kunjalo, phantsi kweemeko eziqhelekileyo zokusetyenziswa, amalaphu aqulunqwe nge-teflon musa ukufikelela kubushushu, esenza ukuba umngcipheko phantse usetyenziswe kwimihla ngemihla.

Imbono elungeleleneyo

I-Teflon isetyenziswe kwiilaphu ikhuselekile ngokubanzi ukuba isetyenziswe yonke imihla. Inika izibonelelo ezininzi, kubandakanya ukumelana nebala kunye ne-lobvity yolonwabo. Nangona kunjalo, njengazo zonke izinto, ukuqonda iipropathi zabo kunye nokusetyenziswa ngokuchanekileyo kubalulekile ekuqinisekiseni ukhuseleko. Inkxalabo ephakanyiswe kwixa elidlulileyo ikhokelele kwiinguqu zemveliso efunekayo, esenza i-teflon esiyisebenzisayo namhlanje kunangaphambili.

Khumbula, ukuhlala unolwazi malunga neemveliso esizisebenzisayo yonke imihla linyathelo elisisiseko lokuba ngabathengi. Njengoko siqhubeka nokuxabisa izinto ezintsha ezinokuphucula ubomi bethu, kufuneka sikwazi ukuqhubela phambili kunye nokhuseleko kuzo zonke iinkalo zemveliso kunye nokusetyenziswa.
