LubMolybdenum Vuam Qwsyog ib qho kev daws teeb meem vuam qib siab uas tsim los rau kev siv kub thiab muaj zog heev. Ua los ntawm molybdenum ntshiab, cov pas nrig vuam no muaj kev ruaj khov zoo, thermal conductivity, thiab tiv taus corrosion, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov lag luam uas xav tau kev ua haujlwm raug thiab kev ntseeg siab hauv cov txheej txheem vuam.
Molybdenum vuam rodssiv rau hauv ntau yam lag luam vim lawv cov khoom zoo heev. Hauv kev lag luam aerospace, lawv zoo tagnrho rau kev vuam cov khoom xws li lub cav dav hlau thiab lub foob pob hluav taws, uas yuav tsum tau tiv taus qhov kub thiab txias heev. Hauv kev lag luam hluav taws xob, lawv ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom ua tau zoo xws li semiconductors thiab cov raj nqus tsev, qhov twg thermal stability yog qhov tseem ceeb. Kev lag luam tsim iav tau txais txiaj ntsig los ntawm nws siv hauv kev vuam cov khoom rau cov cua sov iav yaj thiab lwm yam khoom siv ua haujlwm kub. Kev lag luam nuclear vam khom molybdenum vuam rods los vuam cov khoom reactor thiab lwm yam khoom uas xav tau kev hluav taws xob siab thiab kev tiv taus cua sov. Kev lag luam tsheb kuj siv qhov zoo ntawm nws lub peev xwm los tsim cov khoom ua tau zoo ntawm lub cav thiab cov pa tawm uas ua haujlwm hauv qab cov xwm txheej hnyav.
Molybdenum vuam rodsmuaj ntau yam zoo uas ua rau lawv yog qhov kev xaiv zoo tshaj plaws ntawm cov kws tshaj lij. Kev ua tau zoo ntawm cov cua sov ua kom muaj kev hloov pauv cua sov zoo, txo qhov kev pheej hmoo ntawm kev hloov pauv cua sov thaum vuam. Lub ntsiab lus yaj siab ntawm 2,623°C (4,753°F) ua rau lawv zoo tagnrho rau cov ntawv thov kub heev. Cov pas nrig tiv taus oxidation thiab corrosion, ua kom muaj kev ua haujlwm ntev txawm tias nyob rau hauv ib puag ncig hnyav. Molybdenum lub zog tensile siab ua rau nws zoo tagnrho rau cov ntawv thov vuam uas xav tau kev ruaj khov thiab kev ntseeg siab. Cov khoom sib xws thiab zoo ntawm cov pas nrig tso cai rau kev vuam meej, huv si, txo qhov xav tau rau kev ua tiav tom qab vuam.
Molybdenum vuam rodsLawv paub txog lawv cov khoom zoo thiab tsim qauv yooj yim siv. Ua los ntawm 99.95% molybdenum ntshiab, lawv ua kom muaj kev ua tau zoo tshaj plaws thiab sib xws hauv ntau yam kev siv. Muaj ntau txoj kab uas hla kom tau raws li ntau yam kev xav tau vuam, los ntawm kev ua haujlwm ntxaws ntxaws mus rau cov haujlwm hnyav. Tsim los rau kev yooj yim siv, lawv muaj kev ruaj khov zoo heev thiab tsawg kawg nkaus spatter, ua rau lawv haum rau ob qho tib si tes thiab tsis siv neeg vuam txheej txheem. Sib xws nrog ntau yam kev vuam, suav nrog TIG (Tungsten Inert Gas) vuam thiab plasma arc vuam. Kev tiv thaiv kev puas tsuaj rau ib puag ncig ua kom ntseeg tau tias lub neej txee ntev yam tsis muaj kev cuam tshuam rau kev ua tau zoo.
Peb limolybdenum vuam rodssawv tawm hauv kev ua lag luam rau lawv qhov zoo thiab kev ua tau zoo tsis sib xws. Tsim los rau cov qauv siab tshaj plaws, lawv yog qhov kev xaiv ntau yam thiab txhim khu kev qha rau kev lag luam xws li aerospace, electronics thiab nuclear energy. Kev sib xyaw ua ke ntawm thermal conductivity, lub zog thiab corrosion tsis kam ua rau lawv tsis tseem ceeb rau cov ntawv thov uas xav tau kev ua haujlwm meej thiab ruaj khov. Txawm hais tias koj ua haujlwm nrog cov khoom kub siab lossis cov khoom lag luam tseem ceeb, peb cov molybdenum welding rods xa cov txiaj ntsig zoo sib xws, ua kom koj cov haujlwm ua tau raws li cov qauv zoo tshaj plaws.
Cov electrodes molybdenum yog qhov kev xaiv zoo tshaj plaws rau cov kws tshaj lij uas nrhiav kev daws teeb meem vuam nrog qhov tseeb, ruaj khov thiab kev ua tau zoo hauv cov xwm txheej hnyav. Lawv qhov kev ua tau zoo tshaj plaws thiab ntau yam kev siv ua rau lawv yog cov cuab yeej tseem ceeb hauv kev lag luam uas qhov zoo thiab kev ntseeg siab yog qhov tseem ceeb.
