Teflon txoj kev taug kev los ntawm kev sib tsoo hauv chav kuaj mus rau cov khoom siv hauv cov ntawv thov suav tsis txheeb qhia txog nws qhov tseem ceeb. Nws cov xwm txheej uas tsis yog-stick, ua ke nrog nws lub peev xwm los tiv thaiv qhov kub thiab txias thiab cov tshuaj corrosive, ua rau nws xaiv cov khoom siv hauv ntau qhov chaw. Txawm hais tias nws nyob hauv chav ua noj, ntawm txoj kev, hauv cov chaw tsim khoom, lossis tsev kho mob, cov lus teb rau 'Teflon siv rau dab tsi' yog pom tseeb hauv nws cov ntawv thov dav thiab ntau yam.
Taw qhia rau Teflon (PTFE)
Teflon, ib lub npe zoo sib xws nrog nws cov khoom siv tshuaj lom neeg, polytetrafluoroethylene (PTFE), tau hloov pauv ntau qhov kev lag luam txij li nws qhov kev tshawb pom tsis zoo hauv xyoo 1938 los ntawm Roy J. Plunkett. Qhov kev tsim kho tsis zoo no tau tshwm sim hauv Tebchaws Meskas thaum Plunkett ua haujlwm ntawm cov tub yees. Nws pom tias khov, compressed qauv ntawm tetrafluoroethylene polymerized rau hauv ib tug dawb, waxy khoom, cim lub hnub yug ntawm Teflon.
Dab tsi teev Teflon sib nrug yog nws cov khoom zoo kawg nkaus ntawm cov khoom tshwj xeeb. Nws yog qhov paub zoo tshaj plaws rau nws cov yam ntxwv uas tsis yog-stick, ib qho tshwj xeeb uas tau ua nws lub npe hauv tsev hauv chav ua noj. Teflon-coated cookware yooj yim ua noj thiab tu, sawv cev rau kev nce qib tseem ceeb hauv kev ua zaub mov thiab kev ua noj ua haus. Kev siv Teflon, txawm li cas los xij, ncua deb dhau ntawm chav ua noj.
Nyob rau hauv cov nqe lus ntawm tshav kub tsis kam, Teflon stands rau nws muaj peev xwm tiv taus kub kub yam tsis poob nws cov qauv kev ncaj ncees. Qhov kev ua tau zoo no ua rau nws muaj txiaj ntsig zoo hauv cov txheej txheem tsim khoom uas muaj qhov kub thiab txias, tshwj xeeb tshaj yog nyob rau hauv kev lag luam chemical thiab automotive industries. Nws lub zog siab thiab corrosion-resistant xwm kuj yog vim li cas Teflon txheej yog dav siv nyob rau hauv ntau yam kev siv xws li aerospace, qhov twg kev ntseeg siab thiab kav ntev yog qhov tseem ceeb.
Lwm qhov tseem ceeb ntawm Teflon yog nws cov tshuaj inertness. Nws nthuav tawm tshwj xeeb tsis kam rau cov tshuaj corrosive, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv tshuaj. Qhov kev tiv thaiv no ua kom ntseeg tau tias cov khoom siv Teflon tuaj yeem tswj tau ntau yam khoom tsis muaj degradation, lav lub neej ntev thiab kev nyab xeeb.
Teflon daim ntawv thov hauv kev kho mob tsis tuaj yeem hais ntau dhau.

Teflon hauv chav ua noj thiab cov cuab yeej ua noj
Teflon lub xub ntiag nyob rau hauv chav ua noj, tshwj xeeb tshaj yog nws lub luag hauj lwm nyob rau hauv tsis-stick cookware, yog underpinned los ntawm ib tug nplua nuj ntawm cov ntaub ntawv-rov qab zoo. Nws qhov tshwj xeeb uas tsis yog-stick coefficient, tus cwj pwm los ntawm kev sib txhuam tsis tshua muaj kev sib txhuam coefficient, muab nws sib nrug raws li qhov kev xaiv zoo tshaj plaws rau kev ua noj ua haus. Cov coefficient no tau raug sim ntau nyob rau hauv ob qho tib si cov pa thiab tsis yog cov chaw, qhia Teflon lub peev xwm los tiv thaiv cov khoom noj los ntawm kev ua raws li cov khoom noj khoom haus, txawm tias thaum muaj kev ntxhov siab.
Ib qho ntawm Teflon cov yam ntxwv zoo tshaj plaws yog nws cov cua sov ua kom zoo. Nrog rau qhov kub siab tshaj plaws ntawm kev ua haujlwm siab tshaj 260 degrees Celsius (kwv yees li 500 degrees Fahrenheit), Teflon-coated cookware tuaj yeem tiv taus qhov nruj ntawm kev ua noj hnyav yam tsis muaj hws. Yog tias qhov kub siab tshaj qhov ntsuas no, Teflon tswj nws cov qauv kev ncaj ncees, muab qhov tseem ceeb ntawm kev nyab xeeb tsis nyob hauv chav ua noj.
Tsis tas li ntawd, Teflon's non-stick zog txo qhov xav tau ntawm cov roj ua noj thiab cov rog. Kev txheeb xyuas cov ntaub ntawv nthuav dav qhia tau tias cov lauj kaub uas muaj Teflon yuav tsum muaj txog li 30% cov roj tsawg dua piv rau cov khoom ua noj ua haus, txhawb kev noj qab haus huv thiab ua raws li cov lus qhia zaub mov noj.
Teflon's corrosion-resistant xwm yog lwm cov ntaub ntawv txhawb kev pab, tshwj xeeb tshaj yog nyob rau hauv chav ua noj ib puag ncig uas raug rau ntau yam khoom xyaw thiab noo noo ntau. Kev soj ntsuam nruj tau pom tias Teflon-coated nto tseem tsis muaj kev cuam tshuam rau cov teebmeem corrosive ntawm cov kua qaub, cov hauv paus, thiab lwm yam khoom siv ua noj, ua kom lub neej ntev ntawm chav ua noj.
Hauv cov ntsiab lus, Teflon kev siv dav hauv chav ua noj tsis yog qhov yooj yim xwb; nws yog cov ntaub ntawv-tsav kev xaiv hauv paus nyob rau hauv nws impressive non-stick coefficient, tshwj xeeb tshav kub kuj, thiab zoo-tsim ntaub ntawv txo nyob rau hauv kev siv roj. Nws cov kev tiv thaiv corrosion ntxiv txhawb nws txoj hauj lwm raws li cov khoom siv rau cov neeg nyiam ua noj thiab cov kws tshaj lij.
