Yog vim li cas rau qhov nce ntawm electroplating kuj pab pawg neeg thiab cov txheej txheem ntawm kev txhim kho cov conductivity ntawm electroplating auxiliary anode!

Ib, Muaj ntau ntau qhov laj thawj rau kev nce hauv impedance, feem ntau raws li hauv qab no:

1. Cov tshuaj tiv thaiv anodic oxidation yuav thicken thiab passivate oxide txheej nrog rau lub sijhawm;

2. Vim hais tias titanium phaj nyob rau hauv kev sib cuag nrog lub tsheb npav bar muaj ib tug virtual kev sib cuag los yog nto ntawm lub titanium phaj yog passivated nyob rau hauv high kub;

3. Cov ntsiab lus ntawm conductive nruab nrab hauv cov tshuaj plating yog txo;

4. Lub anode tawg, thiab lub zog sib txuas ntawm platinum txheej thiab substrate raug puas tsuaj;

5. Kev sib cuag tsis zoo ntawm rectifier fais fab mov thiab tsheb npav bar.

Thaum lub impedance ntawm lub plating tank nce, lub tank voltage kuj yuav nce. Thaum lub tank voltage tshaj 10V, qhov tam sim no yuav tsum tsis txhob nce, tab sis tam sim no yuav tsum tau kho kom tsim nyog, xws li: tam sim no yog txo los ntawm 10%, thiab lub sij hawm plating yog ncua los ntawm 10%.

2, txoj kev txhim kho cov conductivity ntawm electroplating auxiliary anode

1. Tshem tawm cov anode thiab khaws cia kom tsis txhob qhuav dej (uas yog, tsis txhob qhuav), muab tso rau hauv 5% hydrochloric acid, tsau rau 2 teev lossis ntev dua raws li qhov xwm txheej tiag tiag, ntxuav lub ntsej muag ntawm lub anode nrog txhuam mos. , thiab ceev faj tsis txhob khawb qhov saum npoo ntawm txheej anode. Feem ntau ntawm cov oxides yuav raug ntxuav tawm. Yog tias cov nyhuv tsis txaus siab, rov ua cov kauj ruam saum toj no. Tom qab ntxuav yooj yim, yaug nrog dej kais dej ntau zaus, thiab thaum kawg yaug nrog dej deionized kom ntseeg tau tias nws tsis muaj fluoride ions ua ntej rov siv dua.

2. Saib seb puas muaj qhov tshwm sim tawg (txheej txheej txheej txheej tshwm sim) ntawm ob sab ntawm lub anode. Yog hais tias qhov saum npoo yog corroded hnyav, lub anode tsis tuaj yeem siv dua. Yog tias ib sab zoo thiab sab nraud yog me ntsis corroded, sab zoo tuaj yeem tig rau kev siv, polished thiab tooj liab bar Tshem tawm cov txheej txheem passivation ntawm titanium phaj nyob rau hauv kev sib cuag, nce qhov concentration ntawm cov tshuaj plating kom tsim nyog, thiab xyuas seb puas cov ntsiab lus ntawm cov khoom siv hluav taws xob yog nyob rau hauv kev sib cuag zoo.

3. Yog tias nws tsis yooj yim rau koj tus kheej, koj tuaj yeem tiv tauj lub chaw tsim tshuaj anode kom rov qab thiab kho cov txheej txheem kom txuag tau cov nqi khoom;

4. Tom qab lub anode tsis siv, ntxuav nws nrog dej deionized thiab tshem tawm lub plating tank, thiab muab tso rau hauv ib tug deionized dej (los yog dej ntshiab) tank cais kom txhob qhuav thiab pab tiv thaiv lub neej kev pab cuam ntawm lub platinum-coated. titanium electrode.
