Baoji Lihua Nonferrous Metals Co., Ltd. (abbreviated li Lihua Titanium) tau tsim nyob rau hauv 2006. Leveraging Baoji txoj kev lag luam zoo thiab nws tus kheej muaj zog technical support, lub tuam txhab tau mob siab rau kev tsim thiab muag khoom ntawm titanium thiab lwm yam nonferrous hlau rau ntau xyoo.
Hauv kev lag luam chlor-alkali kev lag luam- "tshuaj lom neeg sib ntaus sib tua" ntawm kev tawm tsam tsis tu ncua tawm tsam cov xov xwm corrosive heev- ua kom muaj kev nyab xeeb ntawm txhua qhov kev sib txuas yog lub neej rau kev tsim khoom ruaj khov thiab ruaj khov. Tau ze li ob xyoo lawm, Lihua Titanium tau mob siab rau ntawm qhov kev sib tw no, siv zog los ua tus kws tshaj lij hauv kev ua haujlwm ntawm titanium flanges. Kev tawm tsam corrosion yuav tsum tsis yog tsuas yog cov ntaub ntawv zoo heev tab sis kuj mob siab rau thiab txhim khu kev tsim khoom.
PART.01 Corrosion Challenges hauv Kev Lag Luam
Kev lag luam chlor-alkali feem ntau tsim cov dej qab zib caustic, chlorine, thiab hydrogen. Nws cov txheej txheem ntau lawm suav nrog ntau yam kev tshaj tawm corrosive:
- Ib puag ncig chlorine:Ob qho tshuaj chlorine qhuav thiab corrosive ntub dej chlorine yog cov oxidizing thiab corrosive rau feem ntau hlau.
- Hydrochloric Acid Ib puag ncig:Hydrochloric acid ntawm ntau qhov ntau thiab qhov kub thiab txias ua rau muaj qhov muaj zog -acid corrosive ib puag ncig.
- Cov tshuaj chloride:Xws li brine thiab hypochlorite, uas tuaj yeem yooj yim induce pitting corrosion thiab stress corrosion cracking.
- High -Tub kub Caustic Soda:Concentrated caustic soda ntawm qhov kub thiab txias yog corrosive rau ntau yam ntaub ntawv.
Nyob rau hauv xws li "kev sib ntaus sib tua tshuaj," tsoos 304 thiab 316 stainless hlau flanges tawm tsam los muab kev ua haujlwm ntev -. Lawv ua rau corrosion perforation thiab foob tsis ua hauj lwm, ua rau nruab nrab to. Qhov no tsis yog tsuas yog ua rau cov khoom poob thiab ib puag ncig muaj kuab lom tab sis kuj tuaj yeem ua rau muaj kev nyab xeeb loj. Kev kaw rau kev hloov pauv ua rau muaj kev poob nyiaj txiag loj.
PART.02 Titanium as the Game -Changer
Tau ntsib nrog cov teeb meem loj no, kev lag luam tau pom cov kev daws teeb meem txhim khu kev qha hauv titanium, uas qhia tau tias yuav luag zoo tag nrho.
- Corrosion Resistance:Titanium tam sim no tsim ib qhov ntom ntom, ruaj khov oxide zaj duab xis (TiO₂) hauv oxidizing media. Cov yeeb yaj kiab no muaj lub zog ntawm tus kheej - kho muaj peev xwm. Hauv cov tshuaj chlorine ntub, dej chlorine, hypochlorite, thiab cov tshuaj chloride, titanium qhov kev tiv thaiv corrosion yog qhov zoo tshaj rau cov hlau tsis muaj steel, txawm tias ntau tshaj ntawm qee cov hlau muaj txiaj ntsig. Tshwj xeeb tshaj yog nyob rau hauv chloride- muaj ib puag ncig, nws yuav luag tsis muaj zog rau pitting thiab crevice corrosion.
- Mechanical Properties:Titanium muaj lub zog tshwj xeeb (lub zog- rau-} qhov sib piv), tso cai rau lub teeb yuag flange tsim thaum tuav lub zog ntawm cov qauv, uas yuav pab txo cov load ntawm cov kav dej.
- Thermal stability:Nyob rau hauv qhov kub thiab txias muaj feem xyuam nrog chlor- cov txheej txheem alkali, titanium tuav ruaj khov thiab txhim khu kev qha.
Titanium qhov txiaj ntsig zoo ntawm qhov kawg yuav tsum tau muab txhais rau hauv txhua qhov sib txuas muaj zog hauv cov kav dej. Qhov no yog qhov uas Lihua Titanium tau tsom nws txoj kev cog qoob loo tob rau ze li ob xyoo lawm. Peb tshwj xeeb hauv kev hloov pauv siab -cov ntaub ntawv titanium zoo rau hauv siab-kev ua tau zoo titanium flanges los ntawm kev ua kom zoo dua thiab ua haujlwm, ua kom lawv cov kev tiv thaiv corrosion thiab lub zog txhua yam tau ua tiav raws li qhov xav tau.
PART.03 Daim ntawv thov ntawm Titanium Flanges
Tus nqi ntawm titanium flanges yog tshwj xeeb tshaj yog nyob rau hauv tej ntu ntawm chlor-alkali ntau lawm:
- Brine Refining & Electrolysis Tshooj:Hauv cov kav dej ntub dej chlorine, cov tshuab anolyte, thiab dechlorination system piping kev sib txuas, titanium flanges zoo tiv thaiv corrosion los ntawm cov tshuaj chlorides thiab hypochlorous acid, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm electrolytic hlwb.
- Chlorine Processing & Compression Section:Cov khoom siv tseem ceeb xws li hlau anodes, ion- pauv membrane electrolyzers, thiab cov twj tso kua mis anolyte tag nrho yuav tsum muaj cov khoom siv titanium.
- Hydrochloric Acid Synthesis Tshooj:Hauv hydrogen chloride gas thiab hydrochloric acid media pipelines, lub neej kev pab cuam ntawm titanium flanges deb tshaj li ntawm flanges ua los ntawm lwm yam hlau.
PART.04 Nyob rau hauv -Txoj kev muaj zog los ntawm Lihua Titanium
Corrosion yog ib qho yeeb ncuab nyob mus ib txhis hauv chlor-alkali kev lag luam, thiab xaiv cov ntaub ntawv tiv thaiv corrosion yog qhov tseem ceeb rau kev yeej qhov kev sib ntaus sib tua ntev no. Ntawm txhua qhov kev sib txuas tsis yooj yim hauv cov kav dej, Lihua Titanium cov flanges tsim muaj kev tiv thaiv zoo nrog lawv cov kev tiv thaiv zoo corrosion thiab precision- tsim tau zoo.
Hauv kev lag luam chlor-alkali, xaiv cov qib titanium kom raug yog qhov tseem ceeb tshwj xeeb rau kev ua kom muaj kev nyab xeeb, ruaj khov, thiab ntev - cov cuab yeej siv tau ntev. Cov qib sib txawv titanium muaj cov yam ntxwv tshwj xeeb haum rau ntau yam kev ua haujlwm:
| TA1 (Gr.1) | TA2 (Gr.2) | TA9 (Gr.7 / Ti-0.2Pd) | |
|---|---|---|---|
| Cov yam ntxwv tseem ceeb | Qhov zoo tshaj plaws plasticity thiab toughness, qis zog | Feem ntau sib npaug tag nrho kev ua tau zoo, zoo zog / ductility / corrosion kuj | Muaj ~ 0.12% -0.25% palladium (Pd), zoo heev txhim kho corrosion kuj |
| Tensile zog | Ntau dua lossis sib npaug li 240 MPa | Ntau tshaj lossis sib npaug li 400 MPa | Kev txhim kho tseem ceeb piv rau TA2 |
| Tej kev siv | Sib sib sib zog nqus-kos qhov chaw; qis-siab, Tsawg dua los yog sib npaug rau 80℃ib puag ncig (xws li, dilute caustic, brine tank Cheebtsam) | Ua hauj lwm rau feem ntau ib txwm mus rau nruab nrab - kub (~ 150 degree) tej yam kev mob: brine seem, electrolyte piping, ntub dej chlorine piping (flanges, twj tso kua mis casings, valve lub cev) | Siab-temp, siab-kev sib zog, acidic lossis txo cov xov xwm; crevice-qhov chaw nyob (piv txwv li, flange gaskets); cov cuab yeej tseem ceeb nrog kev sib txawv / hloov pauv hloov pauv |
Raws li lub tuam txhab kev lag luam tus qauv thiab lub tuam txhab "Specialized thiab Sophisticated" nyob rau hauv Shaanxi Province, Lihua Titanium tau tsom rau titanium flanges rau 20 xyoo, pab ntau tshaj 5,000 tuam txhab uas muag daws teeb meem kev lag luam corrosion. Yog xav paub ntxiv, thov ua raws li peb tus lej WeChat pej xeem "Lihua Titanium" thiab tawm hauv koj lub tuam txhab npe thiab cov ntaub ntawv tiv tauj. Peb yuav muab koj nrog cov kws tshaj lij los tiv thaiv - kev daws teeb meem corrosion.
