Nyob rau hauv feem ntau aqueous daws, titanium tuaj yeem tsim ib zaj duab xis oxide passive rau ntawm qhov chaw. Yog li ntawd, titanium muaj kev ruaj ntseg zoo nyob rau hauv acidic, alkaline, nruab nrab ntsev daws thiab oxidizing media, uas yog zoo dua li tam sim no stainless hlau thiab lwm yam corrosion kuj ntawm non-ferrous hlau yog zoo, txawm piv rau platinum. Txawm li cas los xij, yog tias oxide zaj duab xis ntawm titanium nto tuaj yeem yaj tsis tu ncua hauv ib qho nruab nrab, titanium yuav raug corroded hauv qhov nruab nrab no. Piv txwv li, titanium yuav corroded nyob rau hauv hydrofluoric acid, concentrated sulfuric acid los yog kub sulfuric acid, hydrochloric acid, thiab phosphoric acid, vim hais tias cov kev daws teeb meem no yuav yaj cov oxide zaj duab xis nyob rau saum npoo ntawm titanium. Yog tias muaj oxidant lossis qee cov hlau ions ntxiv rau cov kev daws teeb meem no, oxide zaj duab xis ntawm titanium nto yuav raug tiv thaiv, thiab kev ruaj ntseg ntawm titanium yuav nce ntxiv. Titanium thiab titanium alloys muaj ntau yam zoo heev, xws li lub zog siab, lub teeb yuag, muaj zog tiv taus, corrosion kuj, thiab lwm yam. Lawv hu ua "cov hlau yav tom ntej" thiab tau cog lus cov khoom siv tshiab. Titanium thiab titanium alloys tsis tsuas yog muaj cov ntawv thov tseem ceeb hauv kev lag luam aviation thiab aerospace, tab sis kuj tau pib siv dav hauv ntau yam kev lag luam xws li kev lag luam tshuaj, roj av, kev lag luam teeb, metallurgy, thiab hluav taws xob, thiab lwm yam.
1. Kev lag luam tshuaj titanium muaj kev ruaj ntseg zoo hauv ntau cov kua qaub, alkali, thiab ntsev tawm, tshwj tsis yog cov saum toj no plaub inorganic acids thiab corrosive txhuas chloride. Yog li ntawd, titanium yog cov khoom siv zoo tshaj plaws hauv kev lag luam tshuaj. Corrosion-resistant cov ntaub ntawv. Nws tau siv ntau thiab ntau dua. Piv txwv li, titanium anodes thiab titanium ntub chlorine gas coolers yog siv nyob rau hauv kev lag luam Chlor-alkali. Nws tau txais txiaj ntsig zoo ntawm kev lag luam. Nws yog lub npe hu ua lub kiv puag ncig loj hauv kev lag luam Chlor-alkali.
2. Petroleum Kev Lag Luam: titanium muaj kev ruaj ntseg zoo hauv cov organic tebchaw, tshwj tsis yog rau tsib cov organic acids (acetic acid, formic acid, trichloroacetic acid, oxalic acid, thiab trifluoroacetic acid) ntawm qhov kub thiab txias. Yog li ntawd, titanium yog cov khoom siv zoo heev hauv cov roj av refining thiab petrochemical kev lag luam uas yuav siv tau los ua ntau yam kub exchangers, reactors, high-pressure hlab ntsha, thiab distillation txhua.
3. Metallurgical Kev Lag Luam: titanium yog ib qho khoom siv hlau nrog zoo nqus pa. Nws yog ib qho zoo tshaj plaws degassing tus neeg sawv cev hauv kev lag luam steelmaking. Nws tuaj yeem ua ke cov pa oxygen thiab nitrogen precipitated los ntawm cov hlau thaum txias. Ntxiv me me ntawm titanium (<0.1%) to="" steel="" can="" make="" the="" steel="" tough="" and="" elastic.="" titanium="" is="" also="" an="" important="" alloy="" additive="" in="" steelmaking,="" aluminum="" making,="" and="" other="" industries.="" titanium="" is="" superconducting="" and="" is="" a="" common="" superconducting="" material.="" in="" addition,="" titanium="" has="" good="" stability="" in="" acidic="" solutions="" containing="" metal="" ions,="" so="" titanium="" has="" a="" very="" wide="" range="" of="" applications="" in="" the="" hydrometallurgical="" industry,="" such="" as="" the="" electrolytic="" production="" of="" non-ferrous="" metals="" such="" as="" copper,="" nickel,="" cobalt,="" and="">
4. Ntawv thiab textile kev lag luam
Titanium muaj qhov tshwj xeeb corrosion tsis kam rau chlorine dioxide, chlorous acid, chlorite, thiab lwm yam tshuaj bleaching. Yog li ntawd, titanium muaj cov ntawv thov tseem ceeb hauv cov khoom siv tshuaj dawb hauv kev lag luam textile thiab dyeing kev lag luam thiab ntawv kev lag luam. Piv txwv li, sub-bleaching tshuab ua los ntawm titanium ua haujlwm zoo. Nyob rau tib lub sijhawm, nws kuj yog siv los ua spinneret hauv kev lag luam xws li hluavtaws fibers.
5. Kev lag luam chiv
Urea yog cov tshuaj chiv tseem ceeb. Hauv cov txheej txheem tsim khoom, urea, ammonia, ammonium carbamate, thiab lawv cov sib tov yog corrosive heev nyob rau hauv kub thiab high-pressure tej yam kev mob. Tom qab hloov stainless hlau nrog titanium, lub neej kev pab cuam ntawm cov cuab yeej yog heev nce, thiab lub sij hawm txij nkawm yuav txo tau heev. Yog li ntawd, cov cuab yeej tseem ceeb hauv urea ntau lawm tam sim no siv titanium.
6. Kev lag luam Desalination thiab Shipbuilding
Lub peev xwm ntawm titanium los tiv thaiv seawater corrosion yog zoo dua li ntawm tag nrho lwm cov hlau, thiab titanium muaj kev ruaj ntseg tshwj xeeb nyob rau hauv zoo li qub los yog high-ceev ntws seawater. Yog li ntawd, titanium yog cov khoom siv zoo tshaj plaws rau cov nroj tsuag desalination. Tus naj npawb ntawm daim ntawv thov titanium hauv daim teb no yuav nce ntxiv. Titanium muaj zog corrosion kuj rau seawater thiab marine huab cua thiab muaj lub zog siab thiab hnav. Nws yog cov khoom siv zoo tshaj plaws rau kev lag luam shipbuilding thiab tau siv dav hauv ntau qhov chaw ntawm ntau lub nkoj thiab cov dej hauv dej tob.
7. Kev lag luam hluav taws xob
Titanium muaj kev ruaj ntseg zoo nyob rau hauv ntau cov dej kub corrosive uas muaj chlorides, sulfides, thiab lwm yam. Yog li ntawd, titanium tau dav siv nyob rau hauv thermal fais fab nroj tsuag ua cua txias kav rau tshav kub exchangers. Tom qab hloov cov tooj liab-nickel alloy raj nrog nyias-walled titanium raj, tsis tsuas yog cov kev pab cuam lub neej yog zoo heev, tab sis kuj lub sij hawm txij nkawm yog heev txo, thiab cov economic nyhuv tseem ceeb heev.
8. Lwm yam
Qhov tseem ceeb feature ntawm titanium yog tias nws muaj zog corrosion kuj. Qhov no yog vim hais tias nws muaj ib tug tshwj xeeb loj affinity rau oxygen thiab muaj peev xwm tsim ib tug ntom oxide zaj duab xis ntawm nws nto, uas yuav tiv thaiv titanium los ntawm nruab nrab corrosion. Titanium tuaj yeem tiv thaiv corrosion ntawm tib neeg lub cev. thiab tsis muaj teeb meem rau tib neeg lub cev. Yog li ntawd, nws tuaj yeem siv dav hauv kev kho mob thiab kev lag luam tshuaj.
