Cov kab lus Teflon thiab PTFE feem ntau pom nyob rau hauv lub neej niaj hnub, thiab lawv feem ntau xa mus rau ob peb qhov kev ua tau zoo heev uas tsis yog-stick txheej lossis cov ntaub ntawv sib khi. Tab sis ntau tus neeg yuav xav tsis thoob yog tias Teflon thiab PTFE yog tib yam khoom. Koj yuav tau txais kev nkag siab zoo txog kev sib txuas ntawm ob lub ntsiab lus hauv tsab ntawv no.
Txhais ntawm PTFE thiab Teflon
Ua ntej, cia peb paub tseeb tias Teflon thiab PTFE to taub. Polytetrafluoroethylene, los yog PTFE luv luv, yog ib tug siab molecular polymer tsim los ntawm dawb radical polymerization ntawm tetrafluoroethylene monomer. Kev ruaj ntseg tshuaj zoo heev, kub tsis kam, insulating zoo, thiab tsis tshua muaj kev sib txhuam coefficient characterize PTFE.
DuPont tau sau npe Teflon ua lub cim lag luam rau lawv cov PTFE kab ntawm cov khoom. Teflon PTFE yog li no tshwj xeeb DuPont PTFE khoom, thiab PTFE tsis yog muaj nyob rau hauv lub npe Teflon. Hauv lwm lo lus, tsis yog tag nrho PTFE raug xa mus rau Teflon; Tag nrho Teflon PTFE yog PTFE.
Kev ua tau zoo ntawm PTFE thiab Teflon
Teflon thiab PTFE muaj cov qauv sib txawv ntawm cov qauv molecular uas tso cai rau lawv los tso saib ntau yam kev ua tau zoo tshaj plaws.
Thaum tshav kub kub tsis kam: Teflon thiab PTFE tiv taus kub; lawv tuaj yeem tiv taus qhov kub li 290 degree thaum siv tsis tu ncua thiab siab li 260 degree thaum siv tsis tu ncua.
Chemical stability: Siv dav hauv cov tshuaj, semiconductor, thiab lwm yam lag luam, PTFE thiab Teflon muaj kev tiv thaiv zoo rau feem ntau cov kua qaub, alkalis, ntsev, thiab cov kuab tshuaj organic. Lawv kuj tsis nkag mus rau cov tshuaj tiv thaiv kab mob.
Tsis tshua muaj kev sib txhuam coefficient: Teflon thiab PTFE yog cov ntaub ntawv zoo tshaj plaws rau kev tsim cov kabmob, cov ntsaws ruaj ruaj, thiab lwm yam khoom uas yuav tsum muaj kev sib txhuam qis vim lawv qhov chaw du heev thiab tsis tshua muaj kev sib txhuam coefficient.
Tsis yog-stick: Teflon thiab PTFE muaj lub zog qis heev, uas ua rau nws nyuaj rau lwm cov ntaub ntawv los lo rau lawv. Lawv yog cov khoom pom zoo rau cov khoom xws li ci pwm thiab cov lauj kaub uas tsis yog-stick vim cov cuab yeej no.
Daim ntawv thov teb ntawm PTFE thiab Teflon
Raws li cov lus hais saum toj no, Teflon thiab PTFE tau siv dav hauv ntau qhov haujlwm.
Cov khoom siv hauv tsev: bakeware, ci pwm, nonstick pans, thiab lwm yam.
Cov ntawv thov kev lag luam: Teflon thiab PTFE yog siv los ua cov kav dej, li qub, cov ntsaws ruaj ruaj, cov ntaub ntawv insulating, thiab lwm yam khoom siv hauv cov khoom siv tshuaj lom neeg, aerospace, tsheb, hluav taws xob, thiab hluav taws xob.
Cov khoom siv kho mob: Cov hlab ntsha thiab cov hlab plawv yog tsim nrog PTFE thiab Teflon vim lawv cov biocompatibility muaj zog thiab tsis muaj toxicity.
Environmental teeb meem ntawm PTFE thiab Teflon
Thaum Teflon thiab PTFE muab ntau yam txiaj ntsig, muaj qee qhov kev txhawj xeeb ib puag ncig cuam tshuam nrog lawv cov kev siv thiab kev tsim khoom. Piv txwv li, cov khoom siv phom sij yuav raug tsim tawm thaum lub sij hawm PTFE txheej txheem, thiab cov pa phem yuav raug tso tawm thaum cov khoom tawg ntawm qhov kub thiab txias. Txhawm rau txo qis kev cuam tshuam ntawm ib puag ncig thiab kev noj qab haus huv rau pej xeem, kev tswj hwm ib puag ncig nruj thiab kev tswj hwm yog li tsim nyog rau kev tsim thiab siv Teflon thiab PTFE.
Cov ntsiab lus
Hauv cov ntsiab lus, cov qauv tshuaj thiab kev ua haujlwm ntawm PTFE thiab Teflon yog tib yam; Txawm li cas los xij, DuPont tshwj xeeb yog hais txog lawv cov khoom PTFE raws li Teflon moniker. Vim yog lawv qhov tshwj xeeb zoo, lawv nquag ua haujlwm hauv ntau lub lag luam; Txawm li cas los xij, lawv qhov cuam tshuam rau ib puag ncig thiab tib neeg kev noj qab haus huv yuav tsum tau muab rau hauv kev txiav txim siab. Nyob rau hauv lub neej yav tom ntej, peb cia siab tias Teflon thiab PTFE yuav muaj kev ruaj ntseg thiab eco-phooj ywg vim kev nce qib hauv kev tshawb fawb thiab thev naus laus zis nrog rau kev nco qab ib puag ncig.
