Anode daim hlau, raws li cov txheej txheem tseem ceeb hauv cov teb xws li electrochemistry, metallurgy, thiab kev tiv thaiv ib puag ncig, tau sib txawv ntawm ntau txoj kev. Txawv cov phiaj hlau muaj cov phiaj xwm tshwj xeeb thiab thov cov xwm txheej vim qhov sib txawv vim cov khoom siv, qauv, lossis hom phiaj. Hauv qab no yog cov lus qhia ntxaws ntxaws los ntawm kev pom ntawm cov khoom, txheej txheem, thiab ua haujlwm.
Kev faib tawm los ntawm cov khoom siv: kev txiav txim siab ntawm kev ua haujlwm yooj yim
Cov khoom ntawm anode phaj ncaj qha txiav txim siab nws conductivity, corrosion kuj, thiab catalytic kev ua haujlwm. Cov kev faib ua ke ib txwm muaj xws li hlau |- raws li, graphite {2} {- raws li.
1. Hlau {-} Raws anode daim hlau
Hlau {-} Based Anode Cov Plates xws li Lead, Titanium, Stainless Hlau, lossis lawv cov alloys thiab yog cov hom siv ntau tshaj plaws. Ua alloy anode daim hlau (xws li cov hmoov txhuas (xws li hilling} Cov roj teeb thiab zinc elecium alloysS) vim lawv tus nqi plab zom mov Titanium -} Base} Cov ntaub ntawv xaiv hluav taws xob (i6}}} Piv txwv li, hauv Chlor - Alkali Ntau Lawm, Titanium- Coated anodes tau ntau dua tsib zaug ntawm graphite anodes.
2. Graphite -} Raws anode daim hlau
Graphite tau siv ntev siv hauv kev siv xws li cov dej electrolysis rau hydrogen ntau lawm thiab txhuas cov kua qaub zoo nkauj (kev ua kom zoo nkauj) thiab kev coj ua. Txawm li cas los xij, ntuj graphite yog nkig thiab muaj cov tshuab hluav taws xob muaj zog los ntawm kev hloov kho ntawm graphite (uas ua tiav qhov ua tiav qhov kev ua kom zoo dua los ntawm kev ntsuas siab dua los ntawm kev ntsuas ntshav siab). Txawm li cas los xij, cov graphite anodes muaj kev cuam tshuam rau oxidation poob hauv cov oxidy oxidizing ib puag ncig muaj peev xwm corkali kev lag luam corrode cov kab graphite). Tam sim no, lawv feem ntau tau hloov los ntawm titanium - coated anodes, tshuav} {} nplai kev siv hluav taws xob.
3. Composite -} Raws anode daim hlau
Txhawm rau hais txog cov kev txwv ntawm cov ntaub ntawv ntawm cov ntaub ntawv, xws li cov qauv siv hluav taws xob (uas ua ke ntawm cov pa roj carbon mones) Cov ntaub ntawv anode, los ntawm cov khoom siv optimized, nthuav qhia tshwj xeeb hauv cov ntawv thov tshwj xeeb (xws li seasater electrolysis thiab kev kho seafingater ntawm high-}} recuatrtration kom haum).
Kev faib tawm los ntawm kev tsim khoom cov txheej txheem: Cov ncauj lus kom ntxaws tswj cov qauv thiab kev ua tau zoo
Kev tsim khoom lag luam ncaj qha rau anode phaj cov microstructure (piv txwv li porosity, piv txwv li cov phaj lossis txiav txim siab txiav txim siab nws cov ntawv thov.
1. Rolled anode daim hlau
Ua los ntawm high - kub dauv ntawm cov hlau nplaum (xws li cov khoom siv tam sim no (xws li hauv hluav taws xob tam sim no (hluav taws xob hauv hluav taws xob). Txawm li cas los xij, lawv cov kev tsis zoo ua rau lawv nyuaj rau hloov kho kom haum rau cov qauv xov tooj electrolytic cell.
2. Stamped / Welded Anode daim hlau
Cov phiaj no tau ntim rau hauv cov duab xws li (xws li cov phiaj duab sib dhos nrog qhov) thiab tom qab ntawd welded nrog kev txhawb nqa pob tw. Lawv feem ntau yog siv nyob rau hauv holometallurgical electrolytic cells (xws li Zinc Electrowowning Cov Hlwb). Lawv lub zog siab muaj zog tso cai rau lawv kom tiv thaiv cov siab ntawm electrolyte yaig thiab anode slime dependition.
3. Coated / sintered anode daim hlau
Rau inert substrates xws li cov khoom siv titanium, ib qho kev ua kom nquag siv los ntawm thermal decomposition (txheej ib lub ruthenium lossis i {kub sintering) lossis electrochemical tso tawm. The key to this process lies in controlling coating thickness (typically 10-50 microns) and adhesion. Piv txwv li, cov txheej ntawm ruthenium - titanium anodes siv nyob rau hauv cintering ncig mus kuaj (txhua tus ntawm 500-600℃kom ntseeg tau kom paub tseeb tias muaj ib puag ncig corrosive heev.
Kev faib tawm los ntawm kev ua haujlwm thiab daim ntawv thov: sib txawv tsim rau cov xwm txheej kev yoog
Raws li cov ntawv thov tiag tiag, anode daim phiaj tuaj yeem muab faib ntxiv rau hauv dav {{cov hom phiaj thiab hom tshwj xeeb.
1. General - lub hom phiaj anode daim hlau
Sawv cev los ntawm txhuas alloy lossis zoo tib yam titanium -}} Cov txheej txheem hluav taws xob (xws li cov khoom siv hluav taws xob (xws li {{1} {}}}}} mohtration kom kho kom zoo nkauj). Lawv cim los ntawm tus nqi qis thiab paub tab, tab sis yuav tsis zoo dua rau ib puag ncig loj (xws li cov tshuaj loj thiab muaj zog alkaline).
2. Tshwj xeeb anode daim hlau
Cov qauv tsim kho tau tsim rau cov xwm txheej tshwj xeeb. Piv txwv li, DSA (cov paib ruaj khov me me) anode daim hlau siv hauv kev kho kom zoo nrog i6} Tantalum Composite i6}} salinity wastewater. Nickel Anode daim hlau siv nyob rau hauv lub electroplating kev lag luam siv ib qho nyiaj me me los txhim kho cov kev sib dhos me me thiab zam kom tsis txhob "kev tsis sib xws". Lithium hlau anode daim hlau siv nyob rau hauv cov khoom- Lub zog hluav taws xob yuav tsum muaj cov txheej txheem tshiab (xws li Ceramic Electrolyte kev loj hlob thiab txhim kho kev nyab xeeb.

Qhov kev faib tawm ntawm anode daim hlau yog qhov tseem ceeb ntawm kev txhim kho kev sib koom tes ntawm cov ntaub ntawv txuj ci, engineering tshuab, thiab thov txais. Los ntawm cov hmoov txhuas tsoos rau niaj hnub - Raws cov qauv tsim qauv, los ntawm cov khoom siv yooj yim kom muaj kev faib tawm tau nce qib hauv cov teb ntsig. Yav tom ntej, nrog kev txhim kho kev tiv thaiv sai thiab kev ua haujlwm ib puag ncig uas ua ke, thiab ib puag ncig cov kev tshawb fawb, txuas ntxiv nthuav tawm thaj chaw tshawb fawb, txuas ntxiv mus rau thaj tsam ntawm anode daim hlau.
