Yuav ua li cas kom ntseeg tau qhov kev ua haujlwm ntawm cov txheej txheem yas electroplating rau hluav taws xob cua sov raj

Kauj ruam tsib ntawm cov txheej txheem yas electroplating: debonding

1, Lub hom phiaj ntawm debonding:

Lub colloidal palladium adsorbed rau ntawm cov yas nto hauv cov tshuaj catalytic tsis muaj kev ua haujlwm catalytic vim nws yog ib puag ncig los ntawm divalent tin ions (Sn2 ntxiv). Nws yog ib qho tsim nyog los yaj cov divalent tin nyob ib ncig ntawm lub palladium los ntawm cov txheej txheem gelation kom nthuav tawm nws thiab tiag tiag muaj cov haujlwm catalytic.

2, Lub hauv paus ntsiab lus ntawm debonding:

Tus neeg sawv cev tso tawm tshem tawm cov tin ions los ntawm cov yas saum npoo, nthuav tawm cov hlau palladium, uas ua raws li cov catalyst hauv kev tsim cov tshuaj nickel.

Qhov liab yog hlau palladium

3, Kev ceev faj:

1. Cov tshuaj rau cov gel tso tawm yuav tsum tau ua kom huv si, yog li yuav tsum muaj lub tshuab lim kom lim nws;

2. Lub sij hawm rau debonding yuav tsum sib phim nrog rau lub sij hawm rhiab heev. Ntev lossis luv luv debonding tuaj yeem ua rau tsis zoo electroplating, plating plating lossis plating;

3. Kev tso tawm gel yuav tsum tau hloov pauv tsis tu ncua lossis txhaj tshuaj ntawm cov tshuaj gel tso tawm tshiab;

4. Ua ntej siv sulfuric acid kom yaj cov kua nplaum, nws yog ib qho tsim nyog yuav tsum tau tseg ib feem los xyuas kom meej cov kev ua ntawm cov kua nplaum.

1, Lub hom phiaj ntawm rhiab heev:

Txhawm rau muab cov nyhuv catalytic rau cov tshuaj plating tom ntej, txhawb kev txo cov tshuaj tiv thaiv thiab nag lossis daus ntawm cov hlau ntawm cov khoom siv hauv cov txheej txheem tom ntej ntawm cov tshuaj plating.

2, Lub hauv paus ntsiab lus ntawm rhiab heev:

Los ntawm kev siv cov nyhuv txo qis ntawm stannous chloride ntawm palladium chloride, lub colloidal complex yog tsim ntawm tetravalent tin ions thiab palladium hlau. Cov hlau palladium yog adsorbed rau ntawm qhov chaw uas tsis yog xim hlau, thiab tom qab ntawd raug thaum lub sij hawm ntxuav, tsim ib tug hlau core ntawm palladium raws li ib tug catalyst rau electroless nickel plating.
