Tshwj xeeb, Precision, thiab Innovation pib nrog xaiv cov khoom zoo
Nyob rau hauv qhov hnyav heev corrosive ib puag ncig ntawm chlor-alkali kev lag luam, "kev noj qab haus huv" ntawm cov khoom tseem ceeb xws li twj, li qub, thiab cov kav xa dej ncaj qha txiav txim siab txog kev nyab xeeb thiab kev ua haujlwm. Titanium, nrog nws qhov tsis sib xws tsis kam tiv thaiv chloride ion corrosion, tau dhau los ua cov khoom tseem ceeb uas tsis tseem ceeb.
Txawm li cas los xij, thaum ntsib cov qib titanium sib txawv xws li GR1, GR2, thiab GR7, ntau tus engineers thiab cov thawj coj yuav ntsib teeb meem xaiv: Dab tsi yog qhov txawv? Qhov twg yog qhov haum rau kuv qhov kev ua haujlwm tshwj xeeb?
Niaj hnub no, Li Hua Titanium, uas yog tus kws tshaj lij titanium flange tob tob hauv kev lag luam chlor-alkali, yuav pab koj nkag siab tob txog peb cov khoom siv titanium no, muab cov lus qhia muaj cai rau koj xaiv cov khoom siv.
I. Common Advantages: Vim li cas Titanium yog qhov kev xaiv zoo tshaj plaws rau Chlor-Alkali Kev Lag Luam?
GR1, GR2, thiab GR7 tag nrho yog cov khoom lag luam ntshiab titanium thiab titanium-palladium alloys. Lawv qhia cov txiaj ntsig tseem ceeb ntawm titanium hlau:
- Zoo heev Corrosion Resistance:In oxidizing media (such as wet chlorine gas, hypochlorites in chlor-alkali production), they form a dense, stable oxide film, offering exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chloride ions – a key advantage over stainless steel.
- Siab zog:Lub zog yog ze rau cov hlau zoo tib yam, tab sis qhov ceev tsuas yog 60% ntawm cov hlau, txo cov khoom siv.
- Kev ua tau zoo:Muaj zoo forging, machining, thiab vuam zog.
II. Kev Ntsuam Xyuas Tus Kheej: "Kev Ua Haujlwm Pyramid" ntawm Peb Cov Khoom Siv Titanium
Peb tuaj yeem saib GR1, GR2, thiab GR7 ua "pyramid" nrog kev nce qib kev ua haujlwm thiab nqi.
1. GR1 (Gr.1) - "Tus Nqi- Kev Xaiv Ua Tau Zoo nrog Cov Ductility Zoo"
- Cov yam ntxwv tseem ceeb:Muaj cov ntsiab lus qis tshaj plaws ntawm impurity ntsiab (xws li oxygen, hlau) ntawm cov khoom lag luam ntshiab titanium qib, ua rau qhov zoo tshaj plaws plasticity, toughness, thiab txias formability, tab sis kuj qis zog.
- Cov ntaub ntawv tseem ceeb: Tensile Strength Ntau dua lossis sib npaug li 240 MPa.
- Kev siv tsim nyog:Ambient lossis qis- qhov chaw siab nrog kev ua haujlwm kub tsis tshaj 80℃. Cov seem uas tsis muaj zog corrosivity, xws li cov tso tsheb hlau luam thiab cov cua kub pauv cov raj rau dilute alkali daws thiab brine.
- Li Hua pom zoo:GR1 yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv nrog cov duab nyuaj uas yuav tsum tau ua kom txias txias. Txawm li cas los xij, nws lub zog yuav tsum tau ua tib zoo ntsuas rau siab - lub twj tso kua mis siab thiab valve flanges.
2. GR2 (Gr.2) - "Golden Balance of Strength and Corrosion Resistance"
- Cov yam ntxwv tseem ceeb:Feem ntau siv, kev sib npaug ntawm cov khoom lag luam ntshiab titanium qib. Nws ua tiav qhov sib npaug zoo ntawm lub zog, plasticity, thiab corrosion kuj, hailed li "tus qauv ntshiab titanium."
- Cov ntaub ntawv tseem ceeb:Tensile Strength Ntau dua lossis sib npaug li 400 MPa. Qhov no yog cov ntaub ntawv teev tseg rau feem coob ntawm cov qauv titanium flanges thiab titanium yeeb nkab fittings.
- Kev siv tsim nyog:Feem ntau 常温 mus rau nruab nrab - kub (~ 150℃) tej yam kev mob hauv chlor-alkali ntau lawm. Flanges, twj tso kua mis, thiab lub cev lub cev hauv qhov chaw tseem ceeb xws li brine seem, electrolyte kwj, thiab ntub dej chlorine gas pipelines.
- Li Hua Perspective:GR2 yog "tus neeg ua haujlwm" thiab "kev xaiv xaiv" rau chlor-alkali twj thiab valve flanges. Tshwj tsis yog cov xwm txheej tshwj xeeb txwv tsis pub lwm tus paub, xaiv GR2 yog kev ntseeg siab rau kev ua haujlwm thiab kev lag luam.
3. GR7 (Gr.7) - "Qhov kawg tiv thaiv rau cov xwm txheej hnyav"
- Cov yam ntxwv tseem ceeb:Raws li GR2, nws ntxiv kwv yees li0.12% ~ 0.25% Palladium (Pd). Qhov kev sib ntxiv ntawm "noble hlau" no ua rau muaj txiaj ntsig zoo hauv kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv kev txo cov xov xwm thiab tsis kam mus rau crevice corrosion.
- Cov ntaub ntawv tseem ceeb:Cov cuab yeej cuab tam yog piv rau GR2, tab sis corrosion kuj yog txhim kho los ntawm kev txiav txim ntawm qhov loj.
- Kev siv tsim nyog:Kub kub, siab concentration, acidic, los yog txo cov xov xwm. Cov ntu tuaj yeem ua rau xeb vim qhov chaw tuag lossis qhov khoob (xws li, ntawm flange gaskets). Cov cuab yeej tseem ceeb uas xov xwm muaj pes tsawg leeg yog qhov nyuaj lossis hloov pauv, yuav tsum muaj kev ntseeg siab.
- Li Hua Interpretation:GR7 yog koj daim npav "ace" rau kev cuam tshuam nrog cov xwm txheej hnyav tshaj plaws thiab xav tau. Nws muab qhov kev nyab xeeb tshaj plaws. Txawm hais tias tus nqi pib yog siab dua, nws tus nqi hauv kev zam kev saib xyuas thiab hloov pauv tag nrho cov cuab yeej siv lub neej yog qhov ntsuas tsis tau.
- Xaus
Hauv kev sib ntaus sib tua nyuaj ntawm chlor-alkali kev lag luam, tsis muaj "universal" cov ntaub ntawv, tsuas yog cov "zoo tshaj plaws" tov. GR1, GR2, thiab GR7 tsim cov ntaub ntawv ua tiav uas npog cov xwm txheej los ntawm kev niaj hnub mus rau qhov kawg.
Li Hua Titaniumtsis tsuas yog muab siab - zoo GR1, GR2, thiab GR7 titanium flanges uas ua raws li ASTM, ASME, GB, thiab lwm yam qauv tab sis kuj yog lub hom phiaj los ua koj tus kws pab tswv yim txhim khu kev qha hauv kev xaiv khoom nrog peb cov kws tshaj lij. Cia peb ua haujlwm ua ke los tsim cov khoom siv muaj zog tshaj plaws rau kev nyab xeeb, ua haujlwm tau zoo, thiab ntev -kev ua haujlwm ntev ntawm chlor-alkali kev lag luam.
