Lub vuam pas nrig yog tsim los ntawm lub vuam pas nrig thiab txheej txheej. Ib qho ntawm cov haujlwm ntawm lub vuam pas nrig yog ua hluav taws xob ua hluav taws xob. Nyob rau tib lub sijhawm, nws tseem yog cov khoom siv tseem ceeb rau kev tsim cov hlau weld. Yog li ntawd, qhov zoo ntawm cov vuam pas nrig tseem cuam tshuam ncaj qha rau kev ua haujlwm ntawm kev sib koom ua ke, thiab cov khoom siv tshwj xeeb tsim. Cov hlau zoo welded carbon steel electrode core feem ntau yog 0.08% C qis carbon steel, feem ntau siv H08 thiab H08A carbon cov ntsiab lus thiab leej faj, phosphorus teeb meem impurities muaj kev txwv hnyav heev ntawm cov khoom siv electrode inch. (Qhov ntawd yog, txoj kab uas hla ntawm cov tub ntxhais electrode yog 2.5 mus rau 6 hli, thiab qhov ntev yog 350 mus rau 450 mm. Txawm hais tias cov electrode muaj peev xwm tiv thaiv kev puas tsuaj sab nraud nyob rau hauv ib txwm muaj, nws tsis tuaj yeem tsis quav ntsej tias nws yooj yim puas vim. Cov khoom siv hluav taws xob tsis zoo yog cov khoom siv ceramic, nws tsis tuaj yeem tiv taus qhov cuam tshuam zoo li cov tub ntxhais hlau, yog li nws tsis tuaj yeem tso nws thaum thauj khoom thiab tshem tawm cov rods uas ntim rau hauv cov thawv tsis tuaj yeem tuav cov hooks Raws li cov txheej txheem tshwj xeeb electrode rau ziab tshwj xeeb, yuav tsum tau ua tib zoo saib xyuas, feem ntau, cov vuam electrode tau ntim rau hauv hnab yas thiab thawv kom tiv thaiv kom tsis txhob ya raws, nws tsis tuaj yeem disassembled ua ntej siv cov electrode sai li sai tau. Yog tias ua tau, qhov seem electrode tom qab vuam raug kaw. . Acid electrodes tsis rhiab rau cov dej noo, thaum cov organic rutile electrodes tso cai rau cov dej ntau dua. Yog li ntawd, raws li cov xwm txheej tshwj xeeb ntawm qhov ntub dej, qhuav ntawm 70-150 degree rau ib teev, lub sij hawm cia luv luv thiab ntim tau zoo, thiab nws tsis tuaj yeem qhuav ua ntej siv. Lub alkaline low-hydrogen electrode yuav tsum tau qhuav ua ntej siv los txo cov ntsiab lus hydrogen ntawm cov electrode thiab tiv thaiv qhov tsis xws luag xws li pores thiab tawg. Qhov kub kom qhuav yog feem ntau 350 ° C rau ib teev. Tsis txhob maj mam muab cov electrode tso rau hauv qhov cub kub kub lossis txias txias kom tsis txhob qhuav tawg. Rau cov kev cai tshwj xeeb ntawm cov ntsiab lus hydrogen, qhov ziab kom qhuav yuav tsum tau nce mus rau 400-500 degree C rau ib mus rau ob teev. Cov alkaline electrode qhuav zoo dua yog muab tso rau hauv lwm qhov chaw tswj qhov kub thiab txias ntawm 50-100 degree C hauv qhov cub kom qhuav thiab siv raws li qhov xav tau. Thaum ziab cov electrode, txhua txheej ntawm vuam rods yuav tsum tsis txhob muab stacked tuab heev (feem ntau 1-3 txheej) kom tsis txhob muaj cua sov thiab noo noo thaum lub sij hawm electrode ziab. Thaum ua haujlwm hauv huab cua qhib, cov electrode yuav tsum tau muab khaws cia kom zoo thaum hmo ntuj thiab tsis tso cai rau khaws cia hauv huab cua qhib. Nws yuav tsum tau muab khaws cia ntawm qhov kub thiab txias tsis tu ncua, txwv tsis pub nws yuav tsum rov ua kom qhuav ua ntej siv hnub tom qab.
Lo lus "tiav" tsis txhais hais tias lub sij hawm cia siab tshaj ib lub sij hawm txwv, tab sis hais txog kev hloov ntawm qhov zoo (tsis zoo). Ntau hom electrodes tau khaws cia rau lub sijhawm ntev, thiab qee zaum cov pob zeb dawb (cov plaub hau) pom nyob rau saum npoo ntawm electrode. Qhov no feem ntau tshwm sim los ntawm iav dej. Cov crystals no tsis muaj teeb meem. Nws txhais tau hais tias cov electrode khaws cia rau lub sijhawm ntev thiab ntub dej. Rau cov electrode uas tau khaws cia rau ntau xyoo, cov txheej txheem yuav tsum tau sim thiab cov electrode yuav tsum qhuav ntawm qhov ntsuas kub. Tsis muaj qhov txawv txav ntawm cov txheej txheem kev ua tau zoo ntawm cov electrode thaum lub vuam, xws li qhov tshwm sim ntawm kev txhaws ntawm cov txheej, thiab qhov tsis xws luag xws li pores thiab tawg, cov khoom siv ntawm cov electrode feem ntau lav. Vim yog xeb me ntsis ntawm cov tub ntxhais wetted, cov electrode yuav tsis cuam tshuam qhov kev ua tau zoo, tab sis nws tsis haum yog tias qhov vuam zoo siab. Cov electrode yog xeb hnyav heev thiab tuaj yeem txo qis raws li qhov tsim nyog lossis siv rau cov khoom siv vuam. Nws yog qhov zoo tshaj rau kev sim nws cov khoom siv kho tshuab raws li lub teb chaws cov qauv thiab tom qab ntawd txiav txim siab txog kev siv nws. Yog tias cov xim vuam muaj ntau cov hmoov hlau, cov av noo ntawm cov txheeb ze yog siab thiab lub sij hawm cia ntev, lub vuam pas nrig yog damp, thiab txawm tias cov xim yog xeb. Txawm hais tias cov electrode qhuav, qhov pores lossis diffusion hydrogen tseem siab thaum lub sij hawm vuam. Thiab yog li ntawd yuav tsum tau muab pov tseg. Kev ntim khoom yuav tsum tau ua los tiv thaiv cov electrode los ntawm absorbing noo noo thiab yuav tsum tau muab cia rau hauv cia. Txhua yam ntawm vuam pas nrig tau raug mob hnyav, thiab cov txheej txheem tau raug tshem tawm tiag tiag. Cov batch ntawm vuam pas nrig yuav tsum tau muab pov tseg.
