Molybdenum electrode kub oxidation kuj, kev pab lub neej ntev
(1) Molybdenum hmoov nrog particle loj xws li 2.5um mus rau 4.4um thiab cov ntsiab lus oxygen xws li 400ppm txog 600ppm yog nias rau hauv molybdenum billets.Tom qab ntawd, cov molybdenum billets tau muab tso rau hauv qhov hluav taws xob tiv thaiv sintering thiab ua ntej sintered nyob rau hauv lub tshuab nqus tsev lossis hydrogen gas ua qhov chaw tiv thaiv.Cov txheej txheem ua ntej sintering yog thawj zaug nce qhov kub ntawm chav tsev rau 4-6 teev rau 1200 ℃, tuav nws rau 2 teev, thiab tom qab ntawd nce qhov kub ntawm 1200 ℃ rau 1-2 teev rau 1350 ℃, tuav nws rau 2-4 teev. teev;
(2) Muab lub pre sintered molybdenum billet nyob rau hauv kauj ruam (1) nyob rau hauv ib tug nruab nrab zaus induction rauv thiab sinter nws nyob rau hauv hydrogen roj raws li ib tug tiv thaiv cua kom tau molybdenum electrodes nrog ib tug zoo purity ntawm tshaj 99.99%.Cov txheej txheem sintering yog raws li nram no: ua ntej, cua sov thiab sinter ntawm chav tsev kub rau 1-2 teev mus rau 1500 ℃, cia nws sov li 1-2 teev, ces sov thiab sinter ntawm 1500 ℃ rau 1-2 teev rau 1750 ℃ , ua kom sov li 2-4 teev, thiab tom qab ntawd ua kom sov thiab sinter ntawm 1750 ℃ rau 1-2 teev rau 1800 ℃ txog 1950 ℃, Ua kom sov li 4-6 teev.
Molybdenum electrode yog cov khoom siv molybdenum electrode uas siv nws qhov tshwj xeeb zoo, qhov kub thiab txias, tsis tu ncua nto, zoo conductivity, ruaj khov npoo, thiab zoo heev corrosion kuj los txhim kho nws tag nrho cov zoo thiab kev pab cuam lub neej.Lub molybdenum electrode muaj ib tug silver grey metallic luster.Qhov no yog ntau yam forged intermediate zaus furnaces tom qab isostatic nias sintering, uas yog ces tig, dov, npaj, thiab hauv av.
Daim ntawv thov ntawm molybdenum electrodes hauv iav kilns yog ib qho ntawm cov laj thawj uas cuam tshuam rau lawv lub neej kev pab cuam, uas tuaj yeem raug ntaus nqi rau cov hauv qab no.Ua ntej, txoj kev ntxig ntawm cov electrodes, xws li sab saum toj ntxig electrode yam tsis muaj electrode cib, tuaj yeem txhim kho lub neej kev pab cuam ntawm lub qhov cub, tab sis nws yog ib qho yooj yim los tsim lub kub saum, thiab cov electrodes yog nquag tawg, uas yuav tsum tau siab heev. rau cov duab ntawm cov khoom nto.Hauv qab ntxig electrode muaj tsawg corrosiveness, tab sis yuav tsum tau tsim ntau dua thiab cov khoom yuav tsum tau ua.Kev yaig ntawm cov pav ca electrode cib yog qhov siab heev.Yog tias tsis muaj kev tiv thaiv tshwj xeeb, nws yuav ua rau kom yaig ntawm qhov cub thiab muaj kev xav tau siab rau kev ua haujlwm thiab siv.
Qhov thib ob yog siv lub tsho molybdenum electrode dej kom raug.Lub tsho dej electrode nrog hauv qab ntxig electrodes yog qhov nyuaj los hloov, yog li cov dej xau loj feem ntau tshwm sim, ua rau lub qhov cub kaw.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tsis tu ncua tshuaj xyuas thiab tswj lub tsho dej thiab cov dej muag muag.Tsis tas li ntawd, cov impurities thiab ntom ntawm molybdenum electrodes kuj muaj qee yam cuam tshuam rau qhov zoo ntawm kilns thiab iav.Qhov kev faib ua feem ntawm cov impurities hauv molybdenum electrodes thiab qhov ntom thiab uniformity ntawm molybdenum electrodes yog cov cim tseem ceeb rau kev ntsuas molybdenum electrodes.Molybdenum electrodes nrog tsawg impurities tuaj yeem tsim iav nrog pob tshab zoo dua.Tsis tas li ntawd, ntau dhau impurities ntawm hlau thiab npib tsib xee hauv electrode tuaj yeem cuam tshuam rau lub neej ntawm electrode.Qhov hluav taws xob nrawm yog qhov tseem ceeb thiab tsis zoo, uas tsis tuaj yeem txhim kho cov kev pabcuam lub neej kom sib xyaw ua ke rau hauv lub khob, tab sis kuj tseem zoo txhim kho kev ua haujlwm ntawm lub khob.
Hauv cov ntsiab lus, molybdenum electrodes feem ntau yog siv hauv kev tsim cov iav thiab lub ntiaj teb tsis tshua muaj kev lag luam.
