Raws li cov khoom siv hluav taws xob tseem ceeb hauv hydrometallurgy thiab electrochemical industries, lub tswv yim tsim ntawm cov hlau lead anode daim hlau tsis tsuas yog cuam tshuam rau lawv cov qauv morphology thiab kev tsim muaj peev xwm, tab sis tseem cuam tshuam ncaj qha rau kev ruaj ntseg, kev siv hluav taws xob, thiab kev pab cuam lub neej ntawm cov txheej txheem electrolysis. Los ntawm qhov ntev - thev naus laus zis evolution, kev tsim cov hlau lead anode daim hlau tau maj mam tsim ib lub tswv yim tseem ceeb ntawm "kev ua tau zoo, kev ua tau zoo, thiab kev ntseeg siab ntawm kev lag luam," sib zog ua kom tau txais txiaj ntsig zoo ntawm cov khoom siv anode nyob rau hauv complex electrochemical ib puag ncig.
Functional adaptation yog lub hauv paus pib ntawm kev tsim. Lub luag haujlwm tseem ceeb ntawm cov hlau lead anode yog kom ruaj khov thauj cov hluav taws xob mus rau cov kev daws teeb meem hauv electrolytic cell, thaum tib lub sijhawm tswj kev sib cais nyob rau hauv lub zog ntawm tam sim no los ua ib zaj duab xis passivation, yog li tswj cov tshuaj tiv thaiv anode txuas ntxiv. Tus qauv tsim yuav tsum txiav txim siab qhov ntev geometric, tuab, thaj chaw zoo, thiab txoj kev ncua ntawm lub phaj anode raws li cov khoom siv electrolyte, qhov ntom ntom tam sim no, thiab cov qauv ntawm cov khoom siv electrolytic. Piv txwv li, nyob rau hauv tooj liab electrolytic refining, lub sulfate system yuav tsum tau lub anode phaj kom muaj zoo txhuas sulfate zaj duab xis tsim muaj peev xwm. Tus qauv tsim yuav tsum xav txog qhov sib txawv ntawm qhov tam sim no ntawm cov phaj saum npoo kom tsis txhob muaj cov yeeb yaj kiab tawg thiab kev tawg sai heev los ntawm qhov muaj zog heev hauv zos tam sim no.
Lub tswv yim ntawm kev ua tau zoo sib npaug permeates tag nrho cov txheej txheem ntawm kev xaiv cov khoom siv thiab kev ua kom zoo dua qub. Thaum cov hlau lead muaj qhov ua tau zoo heev rau sulfate corrosion, cov hlau lead ntshiab tsis muaj zog thiab hardness, ua rau nws yooj yim rau nkag los yog deformation nyob rau hauv ntev hluav taws xob cua sov thiab electromagnetic rog. Yog li ntawd, cov ntsiab lus alloying xws li calcium, tin, thiab antimony feem ntau tau qhia hauv cov qauv tsim los kho cov nplej, txhim kho cov neeg kho tshuab lub zog thiab nkag mus, thaum tuav cov yam ntxwv passivation yam tsis muaj kev puas tsuaj loj. Raws li kev tsim qauv, qhov kev sib haum xeeb ntawm kev txhawb nqa cov tav lossis cov thav duab tuaj yeem ua rau tag nrho cov rigidity thaum txo qhov hnyav, txo qhov kev pheej hmoo ntawm deformation thaum thauj thiab siv. Qhov kev lag luam no- tawm ntawm kev tiv thaiv corrosion, conductivity, mechanical zog, thiab kev ua tau zoo yog qhov kev sib tw tseem ceeb hauv cov hlau lead anode phaj tsim.
Kev ntseeg tau ntawm kev lag luam yog qhov tseem ceeb rau kev tsim qauv. Ntau cov khoom siv lead ua thiab cov smelting thiab cov thev naus laus zis paub tab muab cov xwm txheej rau kev tsim cov nqi qis -. Tus tsim yuav tsum, thaum ua tau raws li qhov yuav tsum tau ua, ua kom yooj yim txoj kev tsim kom ntau li ntau tau, txo cov nyiaj siv ua haujlwm, thiab pab txhawb kev tsim khoom loj thiab kev saib xyuas tom qab. Piv txwv li, siv qhov ntev raws li tus qauv thiab modular ncua kev kawm interfaces tuaj yeem txo cov peev txheej pwm thiab ntawm - qhov teeb meem ntawm qhov chaw; ib tug tsim nyog phaj puab thiab ncua kev kawm ntawv taw tes layout pab kom tusyees faib tam sim no nyob rau hauv lub electrolytic cell, txo lub zog noj thiab txhim kho cathode khoom zoo. Tsis tas li ntawd, tus qauv tsim yuav tsum xav txog kev rov ua dua tshiab ntawm cov phaj anode, kom yooj yim disassembly thiab remelting tom qab nws cov kev pab cuam lub neej, ua raws li kev lag luam thiab ib puag ncig cov kev cai ntawm cov khoom siv rov ua dua tshiab.
Nyob rau theem tsim cov ncauj lus kom ntxaws, yuav tsum tau them nyiaj rau qhov mob thiab kho ntug. Lub phaj du thiab tiaj tiaj ua kom yooj yim tsim cov qauv ntawm cov hlau lead sulfate passivation zaj duab xis, txo qis kev ua tsis tiav ntxov los ntawm qhov tsis xws luag hauv zos; chamfered los yog rounded npoo txo qhov kev ntxhov siab thiab tiv thaiv kev tawg thaum tuav lossis siv. Txoj hauj lwm thiab qhov loj ntawm cov khoom siv hluav taws xob yuav tsum xyuas kom qis - kev sib txuas impedance thiab tsis txhob muaj cua sov hauv zos lossis galvanic corrosion los ntawm qhov tam sim no concentration.
Raws li kev lag luam electrochemical xav tau kom ua tau zoo thiab ntev -cov ntaub ntawv anode lub neej nce, lub tswv yim tsim ntawm cov hlau lead anode daim hlau txuas ntxiv txuas ntxiv cov ntsiab lus tshiab. Piv txwv li, cov lej simulations yog siv los ua kom zoo tshaj qhov kev faib tawm tam sim no ntawm lub phaj nto, txo cov concentration polarization thiab kev siv zog; Cov txheej txheem sib xyaw lossis cov khoom siv gradient tau tshawb nrhiav los txhim kho corrosion kuj nyob rau hauv cov kev ua haujlwm tshwj xeeb thaum tswj xyuas qhov zoo ntawm cov hlau lead matrix.
Zuag qhia tag nrho, nws tus qauv tsim tsis tu ncua nyob ib puag ncig kev ua tiav kev ua haujlwm zoo thiab lub neej ntev tshaj plaws nyob rau hauv cov khoom siv, txhawb kev ua haujlwm tas li ntawm cov txheej txheem electrolysis ib txwm muaj zog thiab kev lag luam.
Hauv cov ntsiab lus, kev tsim lub tswv yim ntawm cov hlau lead anode phaj tseem ceeb ua haujlwm kom haum, siv qhov kev ua tau zoo raws li kev txhais tau tias, thiab tsom mus rau kev ntseeg siab ntawm kev lag luam. Los ntawm kev ua kom zoo ntawm cov ntaub ntawv, cov qauv, qhov ntev, thiab qhov chaw saum npoo, lub anode tswj kev ruaj khov thiab ua haujlwm tau zoo hauv cov khoom siv hluav taws xob tsis zoo, muab cov kev pabcuam zoo rau cov haujlwm xws li tsis yog -ferrous hlau refining, electroplating, thiab lub zog cia technologies.
