Cov txheej txheem ntawm electroplating yas thiab hlau qhov chaw yog txawv

Cov txheej txheem ntawm electroplating yas thiab hlau qhov chaw kuj txawv, thiab kev nkag siab txog kev ua haujlwm ntawm cov txheej txheem no kuj tuaj yeem pab koj nkag siab qhov tseem ceeb ntawm electroplating yas thiab hlau qhov chaw.

Electroplating hlau txheej txheem:

Txawm hais tias cov txheej txheem electroplating ntawm cov hlau sib txawv, nyob ntawm seb qhov yuav tsum tau kho saum npoo thiab cov cuab yeej nyiam ntawm cov neeg ua haujlwm electroplating, cov hlau feem ntau yog electroplated los ntawm cov txheej txheem hauv qab no:

Ntxuav - Cov khoom yuav tsum ib txwm tsis muaj kuab paug uas tuaj yeem cuam tshuam cov txheej txheem electroplating.

Qhuav thiab Pickling - Tom qab ua tiav cov txheej txheem ntxuav, nws yuav tsum tau ntxuav thiab ziab cov khoom. Tom qab ntawd nws yuav tsum tau ntxuav nrog cov kua qaub ua ntej etching tuaj yeem nqa tawm.

Etching - Cov kauj ruam no yuav roughen saum npoo ntawm ib feem, yog li ua kom nws muaj peev xwm ua raws li cov hlau txheej.

Electroplating - Raus qhov chaw hauv lub da dej electroplating, thiab lub sij hawm immersion nyob ntawm qhov tuab ntawm cov hlau txheej.

Rinsing thiab Chemical Rinsing - Tom qab cov khoom raug plated, cov hlau yuav tsum tau siv cov tshuaj yaug, tom qab ntawd yaug nrog dej ntawm qhov kub thiab txias.

Electroplating txheej txheem:

Tom qab cov khoom yas los ua electroplated yog tsim, lawv yuav tsum tau "metallized" los pab lawv ua ntau nplaum rau kom zoo electroplating. Tom ntej no, cov khoom feem ntau yog electroplated los ntawm cov kauj ruam hauv qab no:

Ntxuav - Cov khoom yuav tsum tsis pub dawb los ntawm tej yam khoom uas yuav qhia tau thaum lub sij hawm tsim khoom, xws li av lossis cov ntiv tes.

Ua ntej impregnation - Ua ntej cov kauj ruam tom ntej, cov khoom siv yas yuav tsum tau muab tso rau hauv cov kuab tshuaj los tiv thaiv cov khoom tsis zoo thiab ua kom cov khoom sib txuas yooj yim dua.

Etching - Cov kauj ruam tseem ceeb no txhim kho lub peev xwm ntawm cov khoom yas kom nqus tau cov kua thiab txhim kho lawv cov adhesion rau cov hlau nto.

Kev hloov kho - xaiv tau, nws tuaj yeem ua kom zoo dua electroplating ntawm qhov chaw thiab txhim kho tag nrho cov tsos.

Neutralization - Tom ntej no, tus neeg sawv cev nruab nrab yuav tsum tau siv los tshem tawm cov etchant ntau dhau.

Activation - Tom qab siv lub pre activator, ib feem yuav tsum tau qhib. Activators ua catalysts rau cov txheej txheem electroplating thiab txo tus nqi ntawm rub tawm qhov chaw.

Acceleration - Txawm hais tias lub accelerator txo cov kev hloov pauv hauv lub caij nplooj ntoos hlav, nws lub luag haujlwm tseem ceeb yog tshem tawm stannous hydroxide thiab qhib lub activator.

Immersion hauv da dej tov - Cov tshuaj da dej npog cov khoom yas nrog cov txheej hlau. Qhov kev xaiv ntawm cov hlau los npog qhov chaw yuav txawv nyob ntawm seb qhov yuav tsum tau kho qhov chaw.
