Daim ntawv thov ntawm titanium anode hauv electroplating

Kev siv titanium anode hauv electroplating?

Precious hlau oxide coated titanium anode yog ua los ntawm precious hlau iridium ntsev coated ntawm titanium puag cov ntaub ntawv thiab sintered ntawm kub. Nws yog dav siv hauv electroplating (tooj liab, npib tsib xee, cobalt, kub, zinc, thiab lwm yam), electrolysis (electrolytic tooj liab, npib tsib xee, palladium, rhodium, thiab lwm yam) thiab lwm yam hydrometallurgical industries. Kev npaj thiab kev siv ntawm noble hlau oxide-coated titanium anodes yog heev paub tab, muaj keeb kwm ntawm ntau tshaj 40 xyoo. Piv nrog rau cov txheej txheem ib txwm siv ntawm platinum-plated electrode siv hauv alkaline tooj liab, qhov zoo ntawm titanium anode yog raws li hauv qab no:

1. High tam sim no efficiency, zoo heev corrosion kuj, ntev anode kev pab cuam lub neej, thiab siab tam sim no ceev (txog 10000A / M2).

2. Kev txuag hluav taws xob: Raws li peb txhua tus paub, lub platinum-plated electrode yog lub peev xwm siab-peroxide (1.563V, txheeb ze rau mercurous sulfate) electrode, thaum cov hlau oxide-coated titanium anode yog cov pa oxygen evolution overpotential (1.385V. txheeb ze rau mercurous sulfate). Electrodes, oxygen evolution yog yooj yim dua nyob rau hauv lub anode oxygen evolution cheeb tsam. Yog li ntawd, thaum lub sij hawm electrolysis, lub xov tooj ntawm tes siab kuj tsis tshua muaj, uas txuag tau ntau zog. Qhov tshwm sim no tau pom meej meej nyob rau hauv cov ntawv ci tooj liab tom qab kho alkaline tooj liab plating da dej.

3. Tsis muaj kuab paug: muaj nuj nqis hlau oxide txheej Titanium anode txheej yog ceramic oxide ntawm precious hlau iridium, uas yog ib tug zoo oxide oxide, yuav luag insoluble nyob rau hauv tej kua qaub thiab alkali, thiab oxide txheej tsuas yog 18 ~ 40μm, tag nrho cov txheej muaj tsawg oxide. Yog li ntawd, lub noble hlau oxide-coated titanium anode yuav tsis pollute lub electroplating kua, uas yog yeej ib yam li cov platinum-plated electrode.

4. Kev ua haujlwm siab: Yuav kom ua tiav tib lub neej kev pab cuam ntawm platinum-plated electrodes (txheej thickness 3.5 μm), tus nqi ntawm noble hlau oxide-coated titanium anodes yog li ntawm 80 feem pua ntawm cov platinum-plated electrodes. Noble hlau oxide-coated titanium anode muaj zoo electrochemical stability nyob rau hauv alkaline tooj liab electroplating electrolyte, thiab nws muaj zoo heev electrocatalytic kev ua si thiab durability. Raws li kev txheeb xyuas tus nqi ntawm Baoji Jindeli cov hlau oxide coated titanium anode thiab Pt electrode, nws pom tseeb tias cov hlau muaj nuj nqis oxide coated titanium anode yog kev lag luam.

5. Hauv kev lag luam luam tawm Circuit Board, tooj liab electroplating yuav tsum muaj lub voj voog rov qab tam sim no (PPR). Peb paub tias nyob rau hauv ib puag ncig uas muaj chloride nyob rau hauv lub sulfuric acid system, platinum txheej ntawm platinum-plated titanium anode yuav tev tawm tom qab ua hauj lwm rau ib lub sij hawm. Txawm li cas los xij, kev siv cov hlau oxide-coated titanium anodes tuaj yeem txhim kho qhov tshwm sim no.

6. Tsawg tus nqi tu: Piv nrog cov tshuaj soluble electrodes (graphite thiab lead alloy electrodes), noble hlau oxide-coated titanium anodes tsis tas yuav tsum tsis tu ncua ntau lawm los ntxuav, replenish anodes, los yog nquag hloov anode hnab thiab anodes. Txheej, kom cov khoom tsim tau zoo dua qub thiab cov nqi zog txo;

7. Nyob rau tib lub sijhawm ua haujlwm, kev pabcuam lub neej ntawm noble hlau oxide-coated titanium anodes nyob ntawm qhov ua haujlwm tam sim no ceev, kub thiab da dej muaj pes tsawg leeg.
