Daim ntawv thov kev cia siab ntawm PTFE seals hauv kev tiv thaiv ib puag ncig
Polytetrafluoroethylene (PTFE) cov ntsaws ruaj ruaj, raws li cov khoom siv sealing zoo, tau siv dav hauv ntau qhov chaw lag luam nrog lawv cov kev tiv thaiv corrosion zoo heev. PTFE seals tiv taus ntau yam tshuaj xws li acids, alkalis, thiab ntsev, ua rau lawv ua lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj, tshuaj, thiab zaub mov.
Kev txheeb xyuas corrosion kuj
Kev tiv thaiv corrosion ntawm PTFE seals feem ntau yog vim qhov ruaj khov ntawm lawv cov qauv molecular. Nws qhov tshwj xeeb fluorocarbon daim ntawv cog lus ua rau PTFE tsis tshua muaj zog rau feem ntau cov tshuaj. Cov ntaub ntawv sim tau pom tias tom qab 24 teev ntawm kev nkag mus rau hauv aqua regia (cov kua qaub sib xyaw), PTFE pom yuav luag tsis muaj kev hloov pauv hauv nws qhov chaw, uas yog qhov zoo tshaj rau lwm yam khoom siv. Cov yam ntxwv no ua kom ntseeg tau tias PTFE cov ntsaws ruaj ruaj nyob ruaj khov nyob rau hauv ib puag ncig corrosive heev, yog li tiv thaiv cov xov xwm tawm thiab ua kom muaj kev nyab xeeb ntawm cov khoom siv.
Daim ntawv thov kev cia siab nyob rau hauv kev tiv thaiv ib puag ncig
Nrog rau kev paub thoob ntiaj teb kev paub txog kev tiv thaiv ib puag ncig, muaj kev xav tau ntau ntxiv rau cov ntaub ntawv zoo ib puag ncig hauv kev lag luam. Nrog nws zoo heev corrosion kuj thiab zoo recyclability, PTFE seals qhia tau hais tias muaj peev xwm nyob rau hauv lub tshav pob ntawm ib puag ncig tiv thaiv. Piv txwv li, hauv kev kho cov dej khib nyiab thiab cov pa hluav taws xob kho cov nroj tsuag, PTFE cov ntsaws ruaj ruaj tuaj yeem tiv thaiv kev yaig ntawm cov xov xwm corrosive, ncua kev pab cuam lub neej ntawm cov cuab yeej siv, thiab txo cov pa phem ib puag ncig vim kev xau.
Tsis tas li ntawd, raws li "carbon neutrality" tau dhau los ua lub ntsiab lus kub thoob ntiaj teb, kev txhim kho ntawm lub zog huv si kuj tau muab qhov chaw tshiab rau PTFE seals. Hauv cov khoom siv hluav taws xob tauj dua tshiab xws li hnub ci thiab cua zog, PTFE cov ntsaws ruaj ruaj tuaj yeem siv los kaw cov khoom tseem ceeb kom ntseeg tau tias cov khoom siv ruaj khov hauv qhov chaw hnyav. Nyob rau tib lub sij hawm, nws zoo heev kub-kub kuj ua rau nws lug siv nyob rau hauv high-temperature daim ntawv thov scenarios xws li roj hlwb.
Cov ntaub ntawv txhawb nqa
Raws li Tuam Tshoj Kev Tshawb Fawb Lub Tsev Haujlwm ntawm Puhua Tshawb Fawb Lub Tsev Haujlwm, Tuam Tshoj tau dhau los ua tus tsim khoom loj ntawm PTFE nyob hauv lub ntiaj teb, nrog cov peev txheej tsim tau zoo ntawm 149,600 tons hauv 2020, suav txog li 60% ntawm lub ntiaj teb kev ua lag luam. Nrog rau cov kev cai ib puag ncig nruj zuj zus thiab kev loj hlob sai ntawm kev lag luam huv huv, nws xav tias daim ntawv thov ntawm PTFE cov ntsaws ruaj ruaj nyob rau hauv kev tiv thaiv ib puag ncig thiab lub zog huv si yuav tuav txoj kev loj hlob sai hauv ob peb xyoos tom ntej no.
Xaus
Txhawm rau ua kom tiav, PTFE cov ntsaws ruaj ruaj qhia dav daim ntawv thov kev cia siab hauv kev tiv thaiv ib puag ncig thiab lub zog huv nrog lawv cov kev tiv thaiv zoo heev thiab kev tiv thaiv ib puag ncig zoo. Nrog kev nce qib ntawm kev siv technology thiab kev nthuav dav ntawm kev ua lag luam, PTFE cov ntsaws ruaj ruaj yuav ua lub luag haujlwm tseem ceeb hauv ntau thaj chaw thiab txhawb kev loj hlob ntsuab ntawm kev lag luam ntsig txog.
