Vim li cas cov khoom siv tshuaj nyiam cov khoom siv titanium?
Hauv cov txheej txheem tsim tshuaj niaj hnub no, cov cuab yeej siv feem ntau ua haujlwm nyob rau hauv ib puag ncig uas muaj zog corrosion, siab kub thiab siab, thiab kev sib koom ua ke ntawm ntau yam kev tshaj tawm. Cov xwm txheej no txwv nruj heev rau kev ua haujlwm ntawm cov khoom siv. Cov khoom siv niaj hnub xws li carbon steel thiab stainless hlau yuav raug kev txom nyem los ntawm corrosion perforation, kev ntxhov siab tawg, thiab lwm yam teeb meem nyob rau hauv tej yam kev mob, uas tsis tsuas yog cuam tshuam rau kev tsim khoom tab sis kuj yuav ua rau muaj kev nyab xeeb. Tawm tsam qhov teeb meem no, cov ntaub ntawv titanium tau maj mam sawv tawm vim lawv cov khoom zoo tshaj plaws, dhau los ua qhov kev xaiv tseem ceeb hauv kev tsim khoom siv tshuaj. Los ntawm reactors thiab heat exchangers mus rau piping systems thiab cia tso tsheb hlau luam, daim ntawv thov ntawm titanium txuas ntxiv mus, muab cov khoom txhawb kev ruaj ntseg, ruaj khov, thiab muaj txiaj ntsig ntau lawm.
Exceptional Corrosion Resistance raws li qhov tseem ceeb tshaj plaws
Hauv kev lag luam tshuaj, corrosion yog ib qho tseem ceeb ntawm cov cuab yeej siv tsis ua haujlwm, thiab titanium qhia pom qhov zoo tshaj plaws hauv qhov no:
- Kev tiv thaiv zoo rau cov kua qaub muaj zog (xws li nitric acid thiab hydrochloric acid) thiab alkaline xov xwm
- Tsim cov oxide zaj duab xis ntom ntom hauv qhov chaw oxidizing, muab kev tiv thaiv tus kheej -
- Tswj kev ruaj ntseg hauv chloride- thaj chaw nplua nuj, tiv thaiv pitting thiab crevice corrosion
- Qhov tseem ceeb txuas ntxiv cov cuab yeej siv lub neej thiab txo lub sijhawm poob los ntawm corrosion
Cov cuab yeej cuab tam zoo heev txhim kho cov cuab yeej kev ntseeg siab
Ntxiv nrog rau kev tiv thaiv corrosion, lub zog thiab ruaj khov yog qhov tseem ceeb sib npaug, qhov twg titanium ua tau zoo tshwj xeeb:
- High strength combined with low density supports lightweight equipment design
- Kev qaug zog zoo, haum rau kev ua haujlwm ntev - mus tas li
- Muaj zog cuam tshuam tsis kam, tswj kev ruaj ntseg hauv cov txheej txheem hloov pauv
- Txhim kho tag nrho cov cuab yeej kev nyab xeeb thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav
Zoo heev -Tsuas Ua Haujlwm rau Cov Txheej Txheem hnyav
High - qhov kub thiab txias ib puag ncig yog muaj nyob rau hauv ntau cov txheej txheem tshuaj, xav tau cov ntaub ntawv uas muaj zog thermal stability:
- Khaws cov khoom siv kho tshuab zoo thiab cov qauv kev ruaj ntseg ntawm qhov kub siab
- Muaj zog oxidation tsis kam, tiv thaiv kev ua haujlwm degradation nyob rau hauv tshav kub
- Tsawg thermal expansion coefficient pab txo cov qauv kev puas tsuaj los ntawm thermal stress
- Dav siv nyob rau hauv siab -kub reactors, tshav kub exchangers, thiab cov txheej txheem tseem ceeb
Qhov tseem ceeb Ntev -Cov txiaj ntsig nyiaj txiag lub sijhawm
Txawm hais tias cov ntaub ntawv titanium xav tau kev nqis peev ntau dua, lawv muaj qhov zoo meej rau tag nrho lub neej:
- Lub neej ua haujlwm ntev txo qhov xav tau kev hloov khoom siv ntau zaus
- Cov kev tu ncua tsawg tsawg txo qhov kev kho thiab cov nqi poob qis
- Txhim kho kev tsim khoom txuas ntxiv thiab txo kev cuam tshuam
- Muab cov nqi zoo tag nrho rau kev ua haujlwm ntev -
Raws li kev lag luam tshuaj lom neeg txuas ntxiv mus rau qhov siab dua thiab kev tsim khoom siab dua, qhov kev thov rau siab - cov ntaub ntawv ua tau zoo tau nce tsis tu ncua. titanium cov ntaub ntawv tsis tu ncua ua kom ntseeg tau kev ua tau zoo nyob rau hauv cov xwm txheej hnyav, nrog rau kev nthuav dav ntawm cov khoom siv tseem ceeb. Lawv lub luag haujlwm hauv kev txhim kho kev nyab xeeb, txhim kho kev ua haujlwm zoo, thiab txo cov nqi ua haujlwm ntev - lub sijhawm ua haujlwm tau dhau los ua pov thawj, ua rau lawv yog ib feem tseem ceeb hauv kev tsim kho tshuaj niaj hnub no.
