Molybdenum electrodesua lub luag haujlwm tseem ceeb hauv kev tsim cov iav. Lawv tau siv los ua ib qho chaw hluav taws xob sib xws uas yaj thiab ua rau cov iav, yog li lawv lub neej ntev yog qhov tseem ceeb rau kev ua tiav ntawm cov kab ntau lawm. Txawm li cas los xij, kev pabcuam lub neej ntawm molybdenum electrodes cuam tshuam los ntawm ntau yam.
iav muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm cov iav tuaj yeem ua rau muaj kev cuam tshuam loj rau lub neej kev pabcuam ntawm molybdenum electrode. Qee cov iav iav, xws li cov hlau alkali siab lossis halides, tuaj yeem ua rau molybdenum, ua rau cov electrode degradation sai dua. Tsis tas li ntawd, cov iav uas muaj cov khoom tsis zoo, xws li hlau lossis tooj liab, kuj tseem tuaj yeem ua rau cov electrode degradation sai.
Ua haujlwm kub
Kev khiav hauj lwm kub kuj tseem muaj feem cuam tshuam rau lub neej ntawm molybdenum electrodes, xws li oxidation thiab corrosion ntawm electrode, yog li ua rau nws lub neej luv. Qhov no yog vim hais tias, nyob rau hauv qhov kub thiab txias, molybdenum reacts nrog oxygen thiab lwm yam khoom nyob rau hauv lub iav yaj, ua rau cov oxides thiab lwm yam compounds uas tsis muaj zog electrode thiab ua rau nws yooj yim rau corrosion. Tsis tas li ntawd, qhov kub siab dua nce tus nqi ntawm cov impurities diffuse rau hauv electrode, ntxiv rau nws cov degradation.
tam sim no
Kev pabcuam lub neej ntawm molybdenum electrodes hauv iav kev lag luam kuj cuam tshuam los ntawm tus nqi tam sim no dhau los ntawm electrode. Cov tam sim no siab dua ua rau cov electrode degrade sai dua vim muaj cua sov ntau ntxiv thiab tsim cov chaw kub. Qhov no tuaj yeem ua rau hauv zos melting thiab deformation ntawm electrode, ua rau nws tsis muaj zog thiab ua rau nws muaj kev cuam tshuam rau corrosion thiab lwm yam degradation. Tsis zoo, tam sim no siab dua kuj nce tus nqi ntawm cov impurities diffuse mus rau hauv lub electrode, ntxiv accelerating nws degradation.
Electrode tsim
Kev tsim ntawm molybdenum electrode kuj tseem ceeb heev. Cov yam ntxwv xws li electrode loj, cov duab thiab qhov chaw saum npoo tag nrho cuam tshuam nws cov kav ntev thiab corrosion kuj. Piv txwv li, electrodes nrog thaj chaw loj dua tuaj yeem ua rau oxidation thiab corrosion ntau dua vim yog cov iav yaj ntau dua. Ib yam li ntawd, cov electrodes uas muaj cov duab nyuaj lossis cov kaum ntse ntse tuaj yeem ua rau muaj kev ntxhov siab thiab deformation, uas tuaj yeem ua rau lawv tsis muaj zog thiab ua rau lawv muaj kev cuam tshuam ntau dua.
Kev tu thiab tu
Nrog kev tu thiab tu kom zoo, kev pabcuam lub neej ntawm molybdenum electrodes hauv iav kev lag luam tuaj yeem txuas ntxiv. Los ntawm kev ntxuav thiab tshuaj xyuas lawv tsis tu ncua, txhua yam teeb meem uas tuaj yeem ua rau tsis ua tiav ntxov tuaj yeem kuaj pom thiab daws tau ntxov. Piv txwv li, tshem tawm cov deposits los yog impurities los ntawm ib tug nto tuaj yeem tiv thaiv corrosion thiab lwm yam degradation. Tsis tas li ntawd, kev tshuaj xyuas tsis tu ncua tuaj yeem nthuav tawm cov cim ntawm kev hnav lossis kev puas tsuaj, xws li cov kab nrib pleb lossis khoov, uas tuaj yeem kho lossis hloov ua ntej qhov teeb meem nce mus rau qhov teeb meem loj dua. Kev tuav thiab khaws cia ntawm cov electrodes no tseem ceeb heev los tiv thaiv kev puas tsuaj thiab xyuas kom lawv nyob twj ywm zoo thaum lub sijhawm poob.
