Titanium anode, feem ntau hu ua DSA (dimensionally ruaj khov anode), yog qhov loj me ruaj khov anode. Nyob rau hauv tus txheej txheem ntawm kev siv, nws tsis undergo dissolution cov tshuaj tiv thaiv, thiaj li los tswj qhov seem stability. Yog li ntawd, nws yog ib qho insoluble anode.
Titanium anode tsis yog ib qho yooj yim hlau electrode, tab sis ib txheej electrode: nws yog cov khoom siv hluav taws xob sib xyaw nrog cov hlau titanium ua lub hauv paus hlau thiab electrocatalytic txheej ntawm qhov chaw. Txawm hais tias muaj ntau cov ntaub ntawv tuaj yeem ua rau hauv cov txheej txheem, feem ntau siv yog platinum pawg txheej txheej, feem ntau hu uaPlatinum Coated Titanium Anode, Nws feem ntau suav nrog 3 yam hauv qab no:platinum (hlau), ruthenium oxide, thiab iridium oxide(tag nrho-ceramic hlau oxides). Yog li ntawd, cov anode tuaj yeem txhais tau tias yog cov khoom siv hluav taws xob nrog cov khoom siv hluav taws xob thiab cov tshuaj lom neeg catalytic siab, siv titanium ua cov substrate thiab platinum pawg hlau thiab lawv cov oxides ua cov txheej txheej.
Kev txhim kho keeb kwm ntawm titanium anode
Hais txog nws keeb kwm, uas nws yug los yog sib cais los ntawm Dutch HB npias. Thaum ntxov li xyoo 1957, npias tau ua tus thawj coj hauv kev tsim cov thev naus laus zis ntawm electroplating platinum ntawm titanium, thov rau patent, thiab nrhiav tau magnetochemie (tus thawj coj ntawm machneto tshwj xeeb anode tuam txhab). Xyoo 1967, npias tau tsim txoj hauv kev los ua cov hlau oxide zaj duab xis ntawm titanium hlau. Ib qho ntawm cov kev siv tshwj xeeb ntawm kev siv ruthenium oxide raws li cov anode ntawm cov dej ntsev electrolysis txhawb kev hloov kho zoo ntawm Chlor alkali kev lag luam. Txog rau tam sim no, cov txheej no tseem siv dav hauv ntau yam tshuaj electrochemical chlorine evolution tshwm sim. Nrog rau kev kawm tob ntawm ntau hom platinum pawg hlau thiab lawv cov oxides, iridium tantalum sib xyaw hlau oxide txheej tau ua tiav hauv xyoo 1970, thiab maj mam pib siv rau hauv electrochemical oxygen evolution tshua. Niaj hnub no, cia siab rau nws cov kev ua tau zoo tshaj, cov anode yog dav siv nyob rau hauv ntau yam electrochemical teb, xws li tshuaj lom neeg kev lag luam (Chlor alkali kev lag luam), electrolytic organic synthesis, electroplating, cathodic tiv thaiv, industrial thiab civil electrolytic chlorine disinfection, thiab lwm yam daim ntawv thov teb.
Txij li thaum xyoo 1990,titanium anodetau raug sim thiab siv rau hauv cov txheej txheem PCB tooj liab plating, thiab txuas ntxiv tsim thiab txhim kho nyob rau hauv thawj xyoo caum ntawm lub xyoo pua no. Hauv 10 xyoo dhau los, nrog rau kev txhim kho ntawm PCB cov txheej txheem muaj peev xwm, cov anode maj mam pib hloov cov soluble anode - phosphorus tooj liab pob nrog nws qhov tshwj xeeb zoo. Raws li cov kev xav tau sib txawv electroplating, lub anode tuaj yeem siv tsis tau rau DC electroplating nkaus xwb tab sis kuj rov qab mem tes electroplating. Nyob rau hauv lub neej yav tom ntej, nrog rau kev txhim kho ntxiv ntawm cov txheej txheem tooj liab plating, cov anode kuj tseem yuav raug tsim kho kom haum rau cov txheej txheem electroplating tshiab.
