Piv txwv li, hauv kev kho mob anodizing ntawm aluminium ntawv ci, titanium anode kuj ua tau zoo.

 

 

Platinum txheej: Platinum yog cov hlau muaj txiaj ntsig nrog kev ua haujlwm zoo catalytic thiab ruaj khov, haum rau cov txheej txheem electrolytic uas yuav tsum tau muaj kev ua haujlwm siab catalytic, xws li hydrogen ntau lawm.
Ruthenium-iridium txheej: Ruthenium-iridium txheej muaj kev tiv thaiv corrosion zoo heev thiab kev ua haujlwm catalytic, thiab tshwj xeeb tshaj yog tsim rau cov txheej txheem electrolytic uas yuav tsum tau muaj zog oxidation, xws li kev kho dej khib nyiab.
Lwm cov txheej txheem: xws li iridium-tantalum txheej, platinum txheej, thiab lwm yam, kuj tau siv dav hauv cov txheej txheem electrolytic sib txawv.

 

 

 

 

 

1. Hydrogen ntau lawm los ntawm electrolysis ntawm dej
Nyob rau hauv cov txheej txheem ntawm hydrogen ntau lawm los ntawm electrolysis ntawm dej, titanium mesh chim anode raws li ib tug anode yuav stably tsim oxygen, thiab vim nws zoo heev corrosion kuj thiab electrochemical zog, nws ua kom lub continuation thiab efficiency ntawm cov hydrogen ntau lawm txheej txheem.
Cov kev ua haujlwm siab catalytic ntawm titanium anode pab txo cov overpotential ntawm dej electrolysis thiab txhim kho cov electrolysis efficiency, yog li ua kom cov zis thiab purity ntawm hydrogen.
2. Kev kho dej khib nyiab
Lub titanium mesh chim anode tuaj yeem siv los kho cov dej khib nyiab los ntawm electrolytic oxidation, tshwj xeeb tshaj yog cov dej khib nyiab siab, cov dej khib nyiab uas muaj cov kua qaub lossis alkaline, thiab cov dej khib nyiab.
Nws tuaj yeem tshem tawm cov teeb meem organic thiab cov pa phem hauv cov dej khib nyiab ntawm qhov hluav taws xob siab thiab qhov ceev tam sim no, thiab txhim kho cov dej zoo.
3. Lwm qhov chaw
Tshuaj kws tshuaj: Titanium anodes yog siv los npaj ntau yam organic tebchaw thiab tshuaj intermediates, thiab cov yield thiab purity yog txhim kho los ntawm electrochemical synthesis.
Acid-base electrolysis: Hauv electrolysis ntawm cov kua qaub thiab alkali zoo xws li hydrochloric acid, sulfuric acid, thiab hydrofluoric acid, titanium anodes tuaj yeem hloov cov tshuaj txhuas thiab platinum electrodes, thiab muaj cov khoom zoo corrosion thiab electrocatalytic.
Resistance cua sov: Hauv qee cov txheej txheem kev lag luam, titanium anodes tuaj yeem siv rau cov cua sov ua haujlwm, xws li cua sov catalyst reactors hauv kev lag luam petrochemical.
Kev tswj hwm huab cua: Titanium anodes tuaj yeem siv rau kev kho electrochemical ntawm atmospheric pollutants, xws li tshem tawm NOx thiab SOx.

 

1. Titanium mesh pretreatment
Xaiv cov khoom zoo titanium mesh ua lub substrate.
Sib tsoo thiab ntxuav cov titanium mesh kom tshem tawm cov impurities xws li roj thiab oxide ntawm qhov chaw thiab txhim kho cov adhesion ntawm txheej.
2. Catalyst txheej
Siv iridium thiab lwm yam hlau zoo li catalysts rau saum npoo ntawm titanium mesh. Cov kauj ruam no yog los txhim kho cov kev ua haujlwm catalytic ntawm titanium mesh thaum lub sij hawm electrolysis thiab txhawb cov tshuaj tiv thaiv electrolysis.
