Dab tsi yog cov ntsiab lus tseem ceeb rau kev kho saum npoo ua ntej txheej?
A: Degreasing → xeb tshem tawm → Phosphating / Passivation; xyuas kom huv si saum npoo thiab roughness kom tsis txhob muaj roj stains thiab oxide scale residue uas tuaj yeem ua rau txheej txheej.
Yuav ua li cas kom tsis txhob muaj xim txawv tom qab txheej?
A: Siv cov khoom sib xws, txheej txheej txheej txheej txheej txheej txheej txheej, thiab txheej txheej tsis sib xws; zam dhau qhov sib txawv ntawm qhov roughness.
Nws puas tuaj yeem electroplated?
A: Electroplating yog ua tau; Txhua yam degreasing thiab xeb tshem tawm yuav tsum tau ua ua ntej electroplating kom huv si saum npoo thiab tsis txhob muaj cov txheej txheem adhesion thiab pinholes.
Yuav ua li cas tshem tawm oxide nplai?
A: Txias- dov coils muaj tsawg dua oxide nplai tom qab annealing ib txwm; localized oxidation yuav raug tshem tawm los ntawm pickling thiab polishing; batch processing tuaj yeem ua tiav siv cov kab pickling.
Lub hom phiaj thiab kev xaiv ntawm txheej yog dab tsi?
A: Txhawm rau tiv thaiv khawb thaum thauj thiab ua haujlwm; xaiv cov yeeb yaj kiab qis / nruab nrab / siab adhesion raws li kev ua, thiab tshem tawm cov yeeb yaj kiab tam sim tom qab stamping kom tsis txhob muaj cov nplaum nplaum.
