Cov txheej txheej electroplating ntawm hluav taws xob cua sov raj tig daj, thiab nyob rau hauv mob hnyav, nws tig dub

Qhov siab tam sim no ceev thaj tsam ntawm cov qauv zinc hlau coating tig daj thiab dub, thiab cov teeb meem tseem ceeb yog nyob rau hauv lub teeb emitting kev daws tom qab kev kho mob. Qhov loj feem ntawm nitric acid nyob rau hauv lub plating tov yog {{0}}.1 feem pua ​​rau 0.3 feem pua, uas yog 110 feem pua ​​ntawm cov plating tov. Cov kab ntawm nitric acid tsis tuaj yeem tsim lub teeb, thiab tsuas yog tshem tawm cov ntaub ntawv nyias nyias ntawm cov txheej txheem plating, tuav cov adhesion zoo ntawm txheej plating thiab cov zaj duab xis passivation. Vim tias muaj cov hlau nyob hauv txheej txheej, thaum cov feem ntau ntawm nitric acid ntau tshaj 0.6 feem pua, nws yuav ua rau yellowing; Thaum nws nce mus txog 2 feem pua, lub txheej tig dub. Yog hais tias nws tig daj, luv lub teeb tso zis lub sij hawm rau 1-2 vib nas this. Thaum cov xim daj yog sib sib zog nqus, lub teeb tso zis kua tuaj yeem hloov tau.

1.10 Cov xim txawv txav ntawm cov xim passivation zaj duab xis

Cov xim ib txwm muaj ntawm zinc hlau alloy txheej passivation yog ib yam thiab ci xim. Yog hais tias cov xim yog txawv txav, uas yog, passivation zaj duab xis xim ntawm lub siab tam sim no ntom cheeb tsam txheej yog tsaus dua li lwm qhov chaw, tsim ib tug sib piv. Qhov xim tsaus dua, qhov sib txawv ntau dua. Los ntawm me ntsis ntsuab mus rau tsaus ntsuab, tsaus ntsuab, thiab txawm blackening. Qhov no yog vim muaj cov ntsiab lus hlau siab ntawm cov txheej hauv qhov chaw siab tam sim no. Yog li ntawd, 3 mus rau 5 feeb ua ntej lub plating daim yog tawm ntawm lub tank, qhov ceev tam sim no poob mus txog 1Am2, thiab cov xim txawv qhov txhaum raug tshem tawm.

2 Kev xaus

Hauv cov ntsiab lus, feem ntau ntawm qhov txhaum yog tshwm sim los ntawm kev sib txawv ntawm cov txheej txheem tshwj xeeb thiab cov txheej txheem kev ua haujlwm thaum lub sijhawm tsim khoom. Yog li ntawd, nws tsis yog tsuas yog tsim nyog los txhim kho kev paub txog cov txheej txheem tshwj xeeb, tab sis kuj yuav tsum ua raws li cov txheej txheem kev khiav hauj lwm nruj me ntsis, kom ntau qhov kev ua txhaum ntawm electroplating tuaj yeem "tiv thaiv ua ntej lawv tshwm sim".
