Soda tshauv, raws li cov khoom siv raw hauv kev lag luam tshuaj, tau ntsib teeb meem corrosion loj hauv cov txheej txheem tsim khoom.
Tshwj xeeb tshaj yog nyob rau hauv qhov kev txiav txim ntawm cov pa roj los yog kua theem nruab nrab, cam khwb cia hlau thiab carbon steel khoom yog feem ntau nyuaj rau tiv thaiv qhov ntxeem tau ntawm lub zos corrosion thiab qhov sib txawv corrosion. Txog qhov kawg no, kev lag luam thoob ntiaj teb soda tshauv tau tig mus rau kev siv cov khoom siv titanium kom tau raws li qhov kev sib tw no.
Kev siv dav ntawm titanium hauv cov dej qab ntsev ntau lawm
Nyob rau hauv tus txheej txheem ntawm forging thiab firing soda tshauv, titanium yog dav siv nyob rau hauv distillation gas coolers thiab condensers vim nws zoo heev corrosion kuj. Tshwj xeeb, nyias-walled titanium raj muaj lub neej ua haujlwm txog li 20 xyoo. Qhov no tsis tsuas yog txhim kho cov cua sov hloov pauv, tab sis kuj tseem ua kom thaj chaw sib pauv cua sov ntawm cov khoom siv thiab thaj tsam ntawm cov yeeb nkab yuav tsis raug txo los ntawm xeb, uas yog qhov tseem ceeb tshwj xeeb rau cov distillation condenser.
Hauv Tebchaws Meskas, piv txwv li,titanium cov kav dejyog siv nyob rau hauv zus tau tej cov dej qab zib tshauv es tsis txhob cam khwb cia hlau kav uas yuav tsum tau hloov txhua ob xyoos. Qhov kev pib no tsis tsuas yog txuas ntxiv lub neej kev pabcuam ntawm cov cuab yeej siv, tab sis kuj tseem muaj peev xwm ntau lawm los ntawm 25%. Tsis tas li ntawd, txhawm rau txo cov nqi ntxiv, cov teb chaws txawv teb chaws kuj tau pib siv cov ntshiab titanium nqaim strips los tsim cov yeeb nkab nyias-phab ntsa los hloov cov kav dej seamless, thiab titanium phaj kub exchangers tau dav siv.
Kev xyaum ntawm titanium hauv dej qab zib tshauv ntau lawm hauv Suav teb
Txij li thaum xyoo 1965, Tuam Tshoj kuj tau sim siv titanium los daws qhov teeb meem ntawm cov khoom siv corrosion hauv cov dej qab ntsev ntau lawm. Hauv kev tsim cov dej qab zib tshauv, titanium muaj ntau yam kev siv, suav nrog crystallizing sab nraud coolers, ammonia condensers nyob rau sab saum toj ntawm distillation yees, ammonium chloride niam cawv rhaub, phaj kub exchangers, kaus phaj kub exchangers, carbonization ntauwd txias tubes, carbon. dioxide turbine compressor rotor impeller thiab lalkali twj thiab lwm yam khoom siv tseem ceeb.
Ntawm lawv, carbonization ntauwd yog cov cuab yeej tseem ceeb hauv kev tsim cov dej qab zib tshauv. Hauv carbonization ntauwd, ammonia reacts nrog carbon dioxide los tsim sodium bicarbonate. Txawm li cas los xij, cov yeeb nkab dej txias hauv lub tank dej txias hauv nruab nrab thiab qis ntawm cov pa roj carbonization ntau yog ntsib kev puas tsuaj loj heev. Yav dhau los, txawm tias muaj ntau yam kev tiv thaiv corrosion coatings tau sim, lawv tsis tau daws qhov teeb meem zoo. Lub neej kev pab cuam ntawm cov kav hlau cam khwb cia kuj luv heev. Txij li thaum cov yeeb nkab titanium tau siv los hloov cov yeeb nkab hlau cam khwb cia, tsis pom muaj corrosion tau ntau xyoo, thiab cov txiaj ntsig kev lag luam tau zoo heev.
Tsis tas li ntawd, kev siv ntau ntawm cov twj titanium kuj coj tau ntau yam zoo. Qhov kev sim qhia tau hais tias lub twj tso kua mis titanium tsis yog tsuas yog tiv taus corrosion thiab hnav, tab sis kuj tuaj yeem ua haujlwm ntawm kev ua haujlwm siab ntawm 70% mus rau 80% rau lub sijhawm ntev. Qhov no tsis tsuas yog txuag hluav taws xob, tab sis kuj tseem ua kom tsis muaj cov dej xau, uas txuag cov ntaub ntawv thiab ntxuav ib puag ncig. Qhov tseem ceeb tshaj, lub neej kev pab cuam ntawm lub twj tso kua mis titanium yog ntev li 20 txog 30 xyoo.
Nyob rau hauv cov ntsiab lus, daim ntawv thov ntawm titanium thiab titanium alloys nyob rau hauv soda tshauv ntau lawm qhia tau hais tias zoo heev corrosion kuj thiab high efficiency. Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev txo nqi ntxiv, daim ntawv thov kev cia siab ntawm titanium hauv kev lag luam soda tshauv yuav dav dua.
