Tsis muaj txheej tooj liab nyob rau saum npoo ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov yeeb nkab qhov chaw

Tsis muaj txheej tooj liab tuaj yeem plated rau ntawm qhov chaw; yog vim li cas rau qhov tsis ua hauj lwm no feem ntau yog tshwm sim los ntawm qhov tsis ua hauj lwm ntawm cov tshuaj sensitizing los yog cov tshuaj ua kom muaj zog, thiab nws kuj yuav yog tus nqi pH, kub, formaldehyde, tooj liab sulfate cov ntsiab lus nyob rau hauv cov electroless tooj liab plating tov yog tsawg heev los yog complex tshwm sim. los ntawm cov ntsiab lus siab ntawm qhov sib tov. Txhawm rau daws qhov tsis ua tiav, ua ntej xyuas seb qhov kev daws teeb meem puas, ua kom cov tshuaj lossis cov tshuaj colloidal palladium yog qhov qub. Siv ib qho me me ntawm cov tshuaj sensitizing thiab activating tshiab (los yog cov tshuaj colloidal palladium), yog tias cov khoom siv yas roughened tuaj yeem muab tso rau hauv ib txheej tooj liab tom qab tau kho nrog Minyi npaj tshiab thiab ua kom muaj kev daws teeb meem, nws ua pov thawj tias thawj cov tshuaj sensitizing lossis Activating solution Tsis zoo, cov kev daws teeb meem no yuav tsum tau hloov kho lossis hloov. Yog tias cov khoom siv hluav taws xob muaj xim zoo nkauj tau kho nrog cov thawj sensitizing thiab activating tov, qhov saum npoo ntawm cov khoom tuaj yeem tig xim av, qhia tias cov tshuaj sensitizing thiab cov tshuaj activating tsis ua tiav, thiab cov tshuaj electroless tooj liab plating yuav tsum tau kuaj xyuas.

Lub tshuab nqus tsev electroplating hluav taws xob cua sov raj yuav tsum raug kuaj tom qab tus nqi tsim nyog ntawm formaldehyde

Thaum kuaj xyuas cov tshuaj electroless tooj liab plating, ua ntej kuaj xyuas tus nqi pH thiab qhov kub thiab txias ntawm cov tshuaj, kho tus nqi pH ntawm cov tshuaj mus txog 12, tswj qhov kub ntawm li 30 degree, thiab tom qab ntawd ntxiv qhov tsim nyog ntawm formaldehyde rau kev sim plating. . Yog tias cov khoom tseem tsis tuaj yeem muab tso rau sab sauv tooj liab, cov xim (lub teeb xim) los yog muaj pes tsawg leeg ntawm electroless tooj liab plating tov yuav tsum tau soj ntsuam xyuas seb cov tooj liab sulfate cov ntsiab lus hauv cov tshuaj plating yog tsawg. Yog tias cov ntsiab lus qis, qhov tsim nyog ntawm tooj liab sulfate lub ntsiab ntsev yuav tsum tau ntxiv. Tom qab kev soj ntsuam thiab ua tiav, qhov tshwm sim uas cov khoom tsis tuaj yeem raug plated nrog tooj liab tuaj yeem raug tshem tawm.
