Nickel{0}}molybdenum phaj
Khoom nta
Hauv kev lag luam xws li tshuaj, roj av, thiab tshuaj, uas cuam tshuam nrog cov kua qaub thiab alkalis muaj zog txhua hnub, qhov laj thawj ceev tshaj plaws rau cov khoom siv tsis ua haujlwm feem ntau tsis yog siab, tab sis corrosion. Xaiv lub phaj tsis ncaj ncees lawm tuaj yeem yuam kev kaw ntau lawm rau kev saib xyuas tsis pub dhau rau lub hlis; xaiv lub phaj zoo, txawm li cas los xij, tuaj yeem ua kom tag nrho cov kab ke ua haujlwm ruaj khov rau kaum xyoo. Nickel-molybdenum phaj (tseem hu ua npib tsib xee-molybdenum alloy phaj) yog "kev cawm seej" rau ntau tus qub tub rog engineers- nws tsis yog panacea, tab sis nws ua tau zoo hauv kev txo cov kua qaub ib puag ncig.
Peb tso Mo2 molybdenum phaj ua "cov khoom siv tseem ceeb ntawm siab-kawg lub tshuab nqus tsev siab-cov qauv kub". Nws tsuas yog ua haujlwm rau lub tshuab nqus tsev kho cua sov cov khoom lag luam, ib leeg siv lead ua rauv manufacturers, qhov chaw ua lag luam, thiab cov khoom siv zaj duab xis txheej. Txhawm rau muab nws yooj yim, nws daws qhov mob tseem ceeb ntawm "lub zog siab tshaj 2000 degree, yuav luag tsis muaj volatilisation nyob rau hauv lub tshuab nqus tsev, thiab tsis muaj paug ntawm workpieces". Piv nrog cov hlau tsis muaj steel lossis cov cua sov zoo tib yam- cov hlau tsis muaj zog, qhov "rigidity" thiab "purity" ntawm Mo2 molybdenum daim hlau ntawm qhov kub thiab txias tsis nyob rau tib theem, uas yog qhov tseem ceeb vim li cas nws tuaj yeem tau txais kev ruaj ntseg foothold hauv siab -kawg lag luam.
Nyob twj ywm ntawm qhov kub thiab txias
Thaum ua haujlwm kub ntawm 400-600 degree, nws tuav lub zog zoo thiab tawv, tsis zoo li qee cov hlau tsis zoo uas ua "mos." Qhov no ua rau nws tshwj xeeb tshaj yog haum rau high-temperature evaporators, reactor linings, thiab heat exchanger tube sheets.
Undemanding vuam thiab kev ua haujlwm
Nws qis- carbon tsim (B-3 thiab B-4 txhim kho versions) ua rau tsis muaj kev cuam tshuam ntawm intergranular tom qab vuam. Cov neeg ua haujlwm ntawm qhov chaw tuaj yeem ua tau yooj yim nrog phau ntawv lossis tsis siv neeg vuam, tsis zoo li qee cov nickel alloys uas xav tau kev kho cua sov kom zoo.
Uniform Structure thiab High Purity
Daim hlau los ntawm cov tuam txhab muaj npe nrov muaj cov nplej zoo, tsis muaj kev sib koom ua ke, thiab muaj qhov zoo nkauj zoo nkauj tom qab acid pickling thiab passivation. Lawv yuav tsis hnov dheev pitting lossis crevice corrosion txawm tias tom qab siv sijhawm ntev -.

Cov Khoom Siv Tshuaj
Hydrochloric acid cia tanks, hydrochloric acid synthesis furnaces, sulfuric acid evaporators, phosphoric acid concentrators, acetic acid reactors. Ntau cov tshuaj chlor-alkali nroj tsuag, nroj tsuag tshuaj tua kab, thiab dye nroj tsuag siv npib tsib xee-molybdenum daim hlau rau sab hauv phab ntsa ntawm reactors los yog lub tes tsho ntawm agitator shafts.
Roj thiab Roj
Cov cuab yeej siv roj ntub dej uas muaj hydrogen sulfide thiab chlorides, kev sib sau ua ke saum npoo thiab cov kav dej thauj mus los rau cov roj av acidic, thiab corrosion-cov khoom tiv thaiv rau hydrogenation units hauv cov roj refineries. Yav dhau los, duplex stainless hlau xau tom qab peb xyoos; tam sim no, tom qab hloov mus rau npib tsib xee- molybdenum daim hlau, nws yog qhov ua tau zoo.
Pharmaceuticals thiab Fine Chemicals
Cheebtsam hauv reactors thiab distillation yees xav tau siab purity thiab tsis muaj hlau ion paug. Hauv kev tsim tshuaj nruab nrab, txawm tias me me ntawm cov hlau ions tuaj yeem ua rau cov khoom lwj; lub siab purity ntawm nickel- molybdenum daim hlau yog zoo kawg nkaus haum rau lub hom phiaj no.
Khoom Description
Cia peb qhia meej nws cov khoom muag
Nickel-molybdenum phaj tsis yog ib qho kev hloov kho tshiab ntawm cov hlau tsis zoo ib yam, thiab nws tsuas yog ib qho ntshiab npib tsib xee phaj nrog cov ntaub ntawv ntxiv. Nws yog nyob rau hauv lub niche ua lag luam ntawm siab - kawg tshwj xeeb corrosion- resistant alloy daim hlau, tshwj xeeb tshaj yog hais txog qhov txawv txawv qhov chaw uas stainless hlau "tsis tuaj yeem tiv taus lub siab," ntshiab titanium yog " kim dhau," thiab Hastelloy C-series yog "me ntsis khib nyiab." Cov qib zoo li NS322 (sib npaug rau Hastelloy B-2), B-3, thiab B-4 muaj ntau dua 70% npib tsib xee thiab 26-30% molybdenum, tshwj xeeb tsim los daws teeb meem corrosion hauv kev txo cov xov xwm. Hauv kev ua lag luam, nws feem ntau hu ua "hydrochloric acid-specific phaj" lossis "thawj xaiv rau sulfuric acid evaporators." Nws yog ob peb zaug kim dua 316L, tab sis nws lub neej feem ntau yog 5-10 zaug ntev dua, ua rau nws qhov kev xaiv zoo tshaj plaws nyob rau hauv cov xwm txheej hnyav.
Peb feem ntau hais tias, "Stainless steel daws kev xeb dav dav, npib tsib xee- molybdenum daim hlau daws qhov corrosion tuag." Nws tsis yog rau txhua qhov haujlwm, tab sis tus kws txiav txim plaub- ua rau cov haujlwm uas muaj txiaj ntsig txhua xyoo hauv ntau pua lab, qhov twg ib qho kev kaw ib zaug ua rau ntau lab poob.
Tom qab -Kev Pabcuam Muag
Nickel-molybdenum daim hlau yeej tsis yog qhov kev xaiv pheej yig tshaj plaws, tab sis lawv yog qhov kev ntseeg siab tshaj plaws "ntev- khiav deb." Thaum koj cov kev khiav hauj lwm muaj xws li high-concentration hydrochloric acid, boiling sulfuric acid, los yog siab - qhov kub thiab txias ib puag ncig uas txo cov xov xwm, tsis txhob txhawj txog seb 316L puas txaus- mus ncaj rau nickel- molybdenum daim hlau, txuag koj ntau yam teeb meem. Yog tias koj tab tom xaiv cov ntaub ntawv rau ib txoj haujlwm tshiab lossis tab tom ntsib teeb meem corrosion tsis tu ncua nrog koj cov cuab yeej qub, xav tias dawb xa tuaj rau peb koj qhov kev ua haujlwm tsis zoo (nruab nrab concentration, kub, siab, txaus tus nqi).
