1: Chlor-kev lag luam alkali: cov ntaub ntawv tseem ceeb rau electrolysis thiab chlorine gas kho. Kev lag luam chlor-alkali kev lag luam suav nrog cov xov xwm muaj zog corrosive xws li chlorine gas, hydrochloric acid, thiab brine.
Titanium alloys yog cov ntaub ntawv txheem hauv daim teb no. Electrolysis system: Titanium alloy anode hlwb tuaj yeem ua kom muaj txiaj ntsig tam sim no mus rau 97%, txo lub zog noj los ntawm 15%, thiab tiv taus qhov kub ntawm - kub electrolysis ib puag ncig ntawm brine. Lawv lub neej kev pab cuam yog 5 mus rau 8 xyoo ntev dua li ntawm cov hlau ib txwm muaj. Cov khoom siv kho cov roj chlorine: Titanium ntub chlorine coolers, chlorine gas drying towers, thiab lwm yam khoom siv tuaj yeem ua haujlwm yam tsis muaj corrosion rau ntau tshaj 15 xyoo hauv cov tshuaj chlorine -muaj cov roj ntub dej, txo qis kev saib xyuas los ntawm 80% thiab txo qhov kev pheej hmoo ntawm kev cuam tshuam ntau lawm.
2: PTA cog: Cov khoom tseem ceeb tiv taus acetic acid - bromide corrosion
Hauv kev tsim PTA (purified terephthalic acid), qhov sib xyaw ntawm acetic acid thiab bromide yog hu ua "mob qog noj ntshav ntawm cov ntaub ntawv", vim cov hlau feem ntau ua rau corrosion sai. Titanium alloy yog tib yam khoom uas tuaj yeem tiv taus qhov kev ua haujlwm no ntev. Reactor thiab stirring system: Lub oxidation reactor yog lined nrog titanium alloy, thiab lub nplawm paddle yog ua los ntawm TA10 titanium alloy. Nyob rau hauv ib puag ncig corrosive ntawm 135 degree, nws tuaj yeem siv rau 10 xyoo yam tsis muaj kev hloov pauv, uas yog ntau tshaj 10 npaug ntawm kev pabcuam lub neej ntawm 316L stainless hlau. Cov khoom siv hluav taws xob sib pauv: Hauv cov txheej txheem PTA concentration, titanium alloy kub exchangers tuaj yeem zam qhov teeb meem corrosion tshwm sim los ntawm acetic acid scaling, thiab cov khoom siv hluav taws xob sib pauv tuaj yeem ruaj khov ntawm ntau dua 90% ntawm tus nqi tsim, txo qis kev siv hluav taws xob.
3: Kev Lag Luam Kev Lag Luam Hauv Dej hiav txwv: Cov khoom siv tiv taus dej hiav txwv thiab siab -Ntshav Media
Hauv kev lag luam tshuaj lom neeg hauv hiav txwv (xws li dej hiav txwv desalination, hiav txwv ntsev ntau lawm, thiab cov chaw siv tshuaj nyob rau sab ntug dej hiav txwv), qhov siab - ntsev thiab siab - ib puag ncig cov av xav tau kev tiv thaiv corrosion los ntawm cov ntaub ntawv, thiab titanium alloys sawv tawm. Seawater desalination cov cuab yeej: Titanium raj kub exchangers tau enabled "dej ntau lawm piv" (tus piv ntawm cov dej tshiab uas ua rau seawater noj) nyob rau hauv seawater desalination mus rau ntau tshaj 10: 1, nrog txij nkawm mus txog rau 8 xyoo, txo cov zaus tu los ntawm 60% piv rau tooj liab alloy tshav kub exchangers. Offshore platform chemical systems: Titanium alloy twj, li qub, thiab cov kav dej tuaj yeem ua tiav 30-xyoo lub neej tag nrho yam tsis muaj corrosion los yog to hauv marine ntsev tsuag ib puag ncig, tsis txhob muaj kev pheej hmoo ntawm dej hiav txwv muaj kuab paug los yog xau ntawm cov tshuaj lom neeg vim cov khoom siv corrosion.
04 Kev thauj mus los tshwj xeeb nruab nrab: Hais txog kev xa cov kua dej muaj zog
Hauv kev lag luam tshuaj, nws yog qhov tsim nyog los thauj cov xov xwm tshwj xeeb xws li hydrofluoric acid, chlorine dioxide, thiab concentrated nitric acid. Titanium alloys (tshwj xeeb tshaj yog titanium-palladium alloys) yog cov ntsiab lus tseem ceeb. Kev thauj mus los ntawm Hydrofluoric acid: Ti-0.2Pd alloy yeeb nkab fittings tuaj yeem tiv taus qhov corrosion ntawm cov concentrated hydrofluoric acid, nrog tus nqi corrosion tswj nyob rau hauv 0.01mm / xyoo, daws qhov kev lag luam mob taw tes ntawm "nruam to ntawm cov kav xa dej" hauv cov tshuaj fluorine. Kev thauj mus los Oxidant: Titanium alloy pipeline systems rau chlorine dioxide tuaj yeem siv tau rau lub sijhawm ntev hauv qhov chaw oxidative heev, nrog tus nqi corrosion tsuas yog 0.03mm / xyoo,
ua kom muaj kev nyab xeeb ntawm kev tsim tshuaj tua kab mob thiab kev thauj mus los.
05 Pharmaceutical and Fine Chemical Industry: Dual Assurance of Cleanliness thiab Corrosion Resistance
Kev lag luam tshuaj thiab tshuaj lom neeg muaj kev cai nruj rau ob qho tib si "corrosion resistance" thiab "cleanliness" ntawm cov ntaub ntawv, thiab titanium alloys zoo kawg nkaus haum. Bioreactors: Cov phab ntsa sab hauv ntawm titanium alloy bioreactors, tom qab polishing precision, muaj qhov roughness Ra <0.4μm, uas tuaj yeem tiv thaiv kev loj hlob ntawm microbial thiab ua tau raws li FDA Class A cov qauv kev huv huv, ua rau lawv haum rau siab -kawg siv tshuaj xws li tshuaj tua kab mob thiab tshuaj tiv thaiv. Cov tshuab ntxuav tu: Titanium alloy Cheebtsam hauv CIP (Clean-Hauv-Qhov chaw) cov tshuab tuaj yeem tiv taus lub voj voog tu ntawm 80℃muaj zog alkali thiab siab - dej kub, tsis muaj xeb lossis hlau ion leaching ntev - siv sijhawm, zam kev kis kab mob ntawm cov tshuaj lossis cov khoom noj khoom haus.
Nyob rau hauv lub neej yav tom ntej, txoj kev loj hlob ntawm titanium thiab titanium alloys nyob rau hauv cov tshuaj lom neeg kev lag luam yuav loj hlob los ntawm "irreplaceable" mus ua "ubiquitous". Nrog rau kev txhawb nqa tas mus li thiab kev siv cov khoom siv tshiab, kev tsim khoom hloov pauv thiab hloov pauv ntsuab, tus nqi sib tw ntawm titanium alloys hauv kev lag luam tshuaj yuav nce ntxiv, thiab lawv daim ntawv thov yuav kuj nthuav ntxiv.
