Cov khoom siv tshwj xeeb yuav tsum tau siv rau electroplating kub ntawm hluav taws xob cua sov raj

Kev ceev npib tsib xee kub electroplating siv cov nplaum qhwv cov khoom siv, uas tuaj yeem ua rau muaj kev puas tsuaj rau cov nplaum qhwv qhov chaw tom qab siv ntev. Cov khoom puas yuav muaj potions vim kev tu tsis txaus. Txhawm rau tiv thaiv impurities los ntawm kev nkaum hauv qhov khoom siv, nws yog ib qho tsim nyog yuav tsum tau siv cov khoom siv tshwj xeeb thaum kub plating. Qhov no txhais tau hais tias muaj cov txheej txheem kub plating qhov twg lub phaj sab sauv thiab sab qis yog hloov nrog cov khoom siv. Cov ntawv tshem tawm tam sim ntawd muab tso rau hauv lub tank tu, uas yog ib qho tseem ceeb heev los tiv thaiv lub tog raj kheej kub.

3.3 Nickel / Kub Plated Phaj Da Dej

3.3.1 Cov dej zoo yuav tsum tau ua rau cov phaj tu lub tank

Txawm hais tias nws yog npib tsib xee plated lossis kub plated txij nkawm lub tank, cov dej yuav tsum tau muaj siab, thiab ob qho tib si yuav tsum tau 10 feem pua ​​​​μ DI dej uas tsis muaj conductivity nyob rau hauv s. Tom qab npib tsib xee plating, nws yuav tsum tau ntxiv 1g / L rau 3g / L ntawm citric acid nyob rau hauv cov dej ntawm lub plating tank los tswj cov kev ua ntawm cov nickel nto tom qab npib tsib xee plating.

Tom qab plating, 1g / L txog 3g / L ntawm sodium carbonate yuav tsum tau ntxiv rau cov dej ntawm lub plating tank. Yog hais tias sodium carbonate ntau dhau lawm, nws yuav ua rau kom tawg ntawm cov yeeb yaj kiab qhuav, thiab cov dej qias neeg tsis zoo yuav ua rau lub ntsej muag ntawm lub phaj.

Kev tswj dej kub ntawm lub tank curing

Cov dej txias yuav tsum tau muab tso rau hauv lub tank kho, thiab cov dej kub yuav tsum tau tswj ntawm 18 degree thiab 25 degree. Thaum cov dej kub siab dhau lawm, nickel passivation yuav tshwm sim ntau dua. Tom qab kev txhim kho cov dej txias hauv lub tank tu, peb pom tias qhov teeb meem passivation ntawm cov nickel nto tau zoo tam sim ntawd tom qab kev txhim kho. Qhov teeb meem ntawm kub discoloration ntawm nickel nto passivation yeej tsis pom dua
