Zomwe Zimakhudza Moyo Wautumiki wa Molybdenum Electrodes

 Makampani opanga magalasi ndi bizinesi yachikhalidwe yokhala ndi mphamvu zambiri. Ndi mtengo wokwera wa mphamvu zamafuta komanso kukonza zofunikira pachitetezo cha chilengedwe, ukadaulo wosungunula wasintha kuchokera kuukadaulo wanthawi zonse wotenthetsera moto kupita kuukadaulo wosungunula wamagetsi. Elekitirodi ndi chinthu chomwe chimalumikizana mwachindunji ndi galasi lamadzimadzi ndikudutsa mphamvu yamagetsi kumadzimadzi agalasi, chomwe ndi chida chofunikira mu electrofusion yamagalasi.

 

Molybdenum electrode ndi chinthu chofunikira kwambiri cha electrode mu electrofusion yamagalasi chifukwa cha mphamvu yake yotentha kwambiri, kukana kwa dzimbiri, komanso kuvuta kupanga utoto wagalasi. Tikuyembekeza kuti moyo wautumiki wa electrode udzakhala wautali ngati zaka za ng'anjo kapena kuposa zaka za ng'anjo, koma electrode nthawi zambiri imawonongeka panthawi yomwe ikugwiritsidwa ntchito. Ndikofunikira kwambiri kumvetsetsa bwino zinthu zosiyanasiyana zomwe zimakhudza moyo wautumiki wa ma elekitirodi a molybdenum mu electro-fusion yamagalasi.

 

 

Kuchulukitsa kwa Molybdenum Electrode

Electrode ya molybdenum ili ndi mawonekedwe okana kutentha kwambiri, koma imagwira ndi mpweya pakatentha kwambiri. Pamene kutentha kufika 400 ℃, ndimolybdenumadzayamba kupanga molybdenum makutidwe ndi okosijeni (MoO) ndi molybdenum disulfide (MoO2), amene akhoza kutsatira pamwamba pa molybdenum elekitirodi ndi kupanga okusayidi wosanjikiza, ndi bungwe zina makutidwe ndi okosijeni wa molybdenum elekitirodi. Pamene kutentha kufika 500 ℃ ~ 700 ℃, molybdenum adzayamba oxidizing kuti molybdenum trioxide (MoO3). Ndi mpweya wosasunthika, womwe umawononga chitetezo cha oxide choyambirira kuti malo atsopano omwe amawonekera ndi molybdenum electrode apitirize kukhala oxidize kupanga MoO3. Kuchuluka kwa okosijeni kobwerezabwereza koteroko kumapangitsa kuti ma elekitirodi a molybdenum awonongeke mosalekeza mpaka awonongeke.

 

Zochita za Molybdenum Electrode ku Chigawo cha Galasi

Elekitirodi ya molybdenum imakhudzidwa ndi zigawo zina kapena zonyansa mugawo lagalasi pa kutentha kwakukulu, zomwe zimapangitsa kukokoloka kwakukulu kwa electrode. Mwachitsanzo, yankho lagalasi lomwe lili ndi As2O3, Sb2O3, ndi Na2SO4 monga chowunikira ndizovuta kwambiri pakukokoloka kwa ma elekitirodi a molybdenum, omwe amapangidwa ndi oxidized ku MoO ndi MoS2.

 

Electrochemical Reaction mu Glass Electrofusion

Electrochemical reaction imapezeka mu electrofusion yagalasi, yomwe ili pamalo olumikizirana pakati pa molybdenum electrode ndi galasi losungunuka. Mu hafu yozungulira ya magetsi a AC, ma ion okosijeni olakwika amasamutsidwa ku elekitirodi yabwino kuti atulutse ma elekitironi, omwe amamasula mpweya kuti apangitse okosijeni wa elekitirodi ya molybdenum. Mu AC mphamvu magetsi negative theka mkombero, ena magalasi kusungunula cations (monga boron) kusuntha kwa elekitirodi negative ndi m'badwo wa molybdenum elekitirodi mankhwala, amene ndi madipoziti lotayirira mu elekitirodi pamwamba kuwononga elekitirodi.

 

Kutentha ndi kachulukidwe panopa

Kuchuluka kwa kukokoloka kwa ma elekitirodi a molybdenum kumawonjezeka ndi kuwonjezeka kwa kutentha. Pamene mawonekedwe a galasi ndi kutentha kwa ndondomeko kumakhala kokhazikika, kachulukidwe kameneka kamakhala chinthu chomwe chimayang'anira kuchuluka kwa dzimbiri la electrode. Ngakhale kachulukidwe kakang'ono kovomerezeka ka molybdenum electrode kumatha kufika 2 ~ 3A/cm2, kukokoloka kwa ma elekitirodi kudzawonjezedwa ngati mphamvu yayikulu ikuyenda.
