Molybdenum electrode high kutentha makutidwe ndi okosijeni kukana, moyo wautali utumiki
(1) ufa wa molybdenum wokhala ndi tinthu tating'ono tomwe timachokera ku 2.5um mpaka 4.4um ndi mpweya wochokera ku 400ppm mpaka 600ppm umakanikizidwa ku molybdenum billets. Kenako, ma billets a molybdenum amayikidwa mu ng'anjo yolimbana ndi sintering ndi pre sintered pansi pa vacuum kapena gasi wa hydrogen ngati mpweya woteteza. The pre sintering process imaphatikizapo kukweza kutentha kwa firiji kwa maola 4-6 mpaka 1200 ℃, kuigwira kwa maola awiri, kenako ndikukweza kutentha kuchokera ku 1200 ℃ kwa maola 1-2 mpaka 1350 ℃, ndikuigwira kwa 2-4. maola;
(2) Ikani pre sintered molybdenum billet mu sitepe (1) mu sing'anga pafupipafupi induction ng'anjo ndi sinter pansi mpweya wa haidrojeni monga zoteteza mpweya kupeza molybdenum maelekitirodi ndi khalidwe chiyero kuposa 99.99%. Njira yopangira sintering ili motere: choyamba, kutentha ndi sinter kuchokera kutentha kwa maola 1-2 mpaka 1500 ℃, kutentha kwa maola 1-2, kenako kutentha ndi sinter kuchokera 1500 ℃ kwa maola 1-2 mpaka 1750 ℃. sungani kutentha kwa maola 2-4, ndiyeno tenthetsani ndi sinter kuchokera ku 1750 ℃ kwa maola 1-2 1800 ℃ mpaka 1950 ℃, Khalani otentha kwa maola 4-6.
Molybdenum electrode ndi ma elekitirodi a molybdenum omwe amagwiritsa ntchito maubwino ake apadera, kukana kutentha, kupitilirabe pamwamba, kuwongolera bwino, m'mbali zokhazikika, komanso kukana kwa dzimbiri kuti apititse patsogolo mtundu wake wonse komanso moyo wautumiki. Electrode ya molybdenum ili ndi kuwala kwachitsulo kotuwa. Izi ndi zosiyanasiyana ng'anjo wapakatikati pafupipafupi pambuyo isostatic kukanikiza sintering, amene kenaka atembenuza, adagulung'undisa, anakonza, ndi pansi.
Kugwiritsa ntchito ma elekitirodi a molybdenum mu ng'anjo zamagalasi ndi chimodzi mwazifukwa zomwe zimakhudza moyo wawo wautumiki, zomwe zingabwere chifukwa cha izi. Choyamba, njira yoyika ma elekitirodi, monga ma elekitirodi omwe amayikidwa pamwamba popanda njerwa za elekitirodi, amatha kuwongolera moyo wautumiki wa ng'anjo, koma ndizosavuta kupanga pamwamba pamoto, ndipo ma elekitirodi amatha kusweka, zomwe zimafunikira zofunika kwambiri. kwa mawonekedwe a zinthu pamwamba. Elekitirodi yoyika pansi imakhala ndi corrosiveness pang'ono, koma imafunikira mapangidwe apamwamba ndi zofunikira za zida. Kukokoloka kwa njerwa za lathyathyathya elekitirodi ndi mkulu. Ngati njira zodzitetezera zapadera sizitsatiridwa, zidzakulitsa kukokoloka kwa ng'anjo ndikukhala ndi zofunikira zazikulu zogwirira ntchito ndikugwiritsa ntchito.
Chachiwiri ndikugwiritsa ntchito jekete lamadzi la molybdenum electrode molondola. Chovala chamadzi cha elekitirodi chokhala ndi maelekitirodi oyika pansi ndizovuta kusintha, chifukwa chake nthawi zambiri kutayikira kwamadzi kumachitika, zomwe zimapangitsa kuti ng'anjo itseke. Choncho, m'pofunika kuyang'anitsitsa nthawi zonse ndikusunga jekete lamadzi ndi madzi ofewa. Kuonjezera apo, zonyansa ndi kachulukidwe ka ma elekitirodi a molybdenum amakhalanso ndi zotsatira zina pa khalidwe la ma kilns ndi galasi. Kuchuluka kwa zonyansa mu ma elekitirodi a molybdenum ndi kachulukidwe ndi kufanana kwa ma elekitirodi a molybdenum ndizizindikiro zofunika pakuyezera ma elekitirodi a molybdenum. Ma electrode a Molybdenum okhala ndi zonyansa zochepa amatha kupanga magalasi owoneka bwino. Kuphatikiza apo, zonyansa zambiri zachitsulo ndi faifi tambala mu elekitirodi zingakhudzenso moyo wa elekitirodi. Kachulukidwe ka ma elekitirodi ndi okwera komanso yunifolomu, zomwe sizingangowonjezera moyo wautumiki wa elekitirodi, kupewa kukokoloka kwa ma elekitirodi, ndikupangitsa kuti tinthu tambiri ta molybdenum zisakanizidwe mugalasi, komanso kuwongolera magwiridwe antchito agalasi.
Mwachidule, ma elekitirodi a molybdenum amagwiritsidwa ntchito makamaka popanga magalasi ndi mafakitale osowa padziko lapansi.
