Teflon txheej hauv tsev yuav yog cellular lossis du, tab sis lub hlwb nce qhov cua kub nto thiab txhawb ntau tshaj cua sov. Thaum muas Teflon cookware, nco ntsoov tias lub hauv qab ntawm cov tais diav yog kiag li tiaj. Nws yooj yim zoo nkauj los xyuas, cia li muab tus pas ntsuas rau hauv qab. Nws yog ib qho tseem ceeb kom muaj lub txaj hauv qab nrog lub qhov cub hluav taws xob hauv qhov cub hluav taws xob. Yog hais tias lub qab ntim ntawm lub tais yog me ntsis curved, ces, ua tsaug txawm tias me ntsis deflection, npaj mus them tshaj rau cov nqi hluav taws xob, thiab cov khoom noj yuav tau npaj kom ntev zog.
Nyob rau hauv lub ntiaj teb niaj hnub no, ntau hom Teflon coated cov tais diav tau txais kev paub zoo, feem ntau nws yog siv los ntawm cov chaw ua lag luam pej xeem, vim cov tais diav yooj yim siv thiab ua kom txo cov nqi roj.
Teflon muaj cov khoom zoo heev. Nws yog ib yam khoom siv pob tshab dawb ntawm cov xim dawb, zoo ib yam li cov tsos kom pom muaj polyethylene los yog paraffin. Teflon tiv taus cov high txias, thiab kuj frost-resistant - thaum kub ntawm -71 rau 270 ° C nws retains nws muaj peev xwm nyob twj ywm elastic thiab saj zawg zog. Nws kuj muaj kev npliag insulating zoo heev.
Teflon txheej muaj lub siab ua haujlwm - nws deb tshaj tag nrho tam sim no zoo-paub noble hlau thiab cov khoom siv hluavtaws. Acids, nrog rau cov mixtures ntawm hydrochloric thiab nitric acids, thiab alkalis tsis tua nws los ntawm nws cov kev txiav txim. Teflon tua tsuas yog chlorine trifluoride, alkali hlau melts thiab fluorine.
Teflon tau tsim los ntawm American firm DuPont, cov tshuaj fluorine uas muaj polymer tau pom los ntawm ib tug kws kho mob Roy Plunkett hauv xyoo 1938. Qhib rau hauv cov kev sim, cov khoom siv tshiab yog cov nplua thiab cov nplaum, thiab nws pib nrhiav cov ntawv hauv ntau qhov chaw. Tab sis txij li thaum tsis muaj dab tsi nyam rau cov ntaub ntawv nplua, nws tau txais nws lub koob npe nrov li ib qho zoo heev uas tsis yog lo lo. Ua ntej qhov no, cov tub rog xav paub, yam khoom siv txuj ci tseem ceeb li cas, lawv pib siv Teflon ua tus txheeb ze los tiv thaiv lub foob pob hluav taws xob los ntawm cov qauv tsim hluav taws xob. Thiab tsuas yog tom qab ntawd, thaum xyoo 1950, cov tais diav uas tau them nrog Teflon pib ua.
Cov ntaub ntawv pov thawj coated nrog Teflon yog muag heev, thiab yog li ntawd yuav tsum tau ceev faj kev kho mob. Npog yog yooj yim rau kev puas tsuaj, yog li ntawd, thaum npaj zaub mov hauv nws, tsis txhob siv cov khoom ntse hlau - lub diav rawg, rab riam thiab lwm yam. Yog tias muaj khawb ntawm lub Teflon txheej, cov kua qaub thiab roj los ntawm cov khoom nkag mus rau hauv lub hauv paus hlau ntawm cov tais diav. Lawv yuav pab tshem tawm cov yeeb yaj kiab, ces Teflon thiaj poob tag nrho nws cov khoom tsis yog. Nws yog qhov zoo tshaj plaws los siv thaum ua noj ua haus nrog cov roj hmab ntoo.
Yog tias tais diav tshiab, ces nws yuav tsum tau ntxuav nrog xab npum sov so, los yog koj tsuas ua tau dej hauv nws. Ces grease nws nrog zaub roj. Teflon cookware yog luv luv-nyob, nws yuav kav ntev li ob rau tsib xyoos. Yog tias qhov tiv thaiv txheej txheem yog tuab thiab ntxhib, ces cov tais diav yuav ntev thiab yuav ua haujlwm tau ntev txog kaum lub xyoo.
Tsis txhob muaj kev hloov hauv kub thiab poob siab - yog tias overheated, koj lub lauj kaub khov los yog yias tau yooj yim poob nws cov khoom tsis yog, thiab los ntawm kev cuam tshuam, nyias tais tau yooj yim deformed. Ua tib zoo ntxuav no tais nrog ib daim txhuam cev thiab ib lub kua xab npum.
Txawm li cas los xij, raws li nws tau nrhiav tsis ntev los no, cov tais diav nrog Teflon txheej yuav ua rau muaj mob loj. Thaum siab kub, Teflon zaj duab xis decomposes thiab tso tawm ntawm perfluorooctanoic acid pib, uas yog teeb meem heev rau kev noj qab haus huv thiab muaj peev xwm zwm nyob rau hauv ib puag ncig thiab tib neeg cov ntshav. Nws kuj tau raug pov thawj tias qhov tshuaj no ua rau oncological kab mob thiab tsis ntev dhau los perfluorooctanoic acid tau lees paub tias yog tus kabmob feemcoob carcinogen. Cov tuam txhab uas tsim cov hom cookware no, tsis lees paub tias lawv cov tais diav yog teeb meem.
