Kev siv cov brightener rau hluav taws xob cua sov raj

Kev noj cov brightener nyob rau hauv acidic ci tooj liab plating tov yog muaj feem xyuam rau ntau yam, xws li hom, zoo, deg lub xeev ntawm workpiece, raws li zoo raws li lub loj concentration ntawm inorganic thiab organic impurities thiab tooj liab sulfate nyob rau hauv lub plating tov. Tshwj xeeb tshaj yog nrog tsis txaus Cl -, nws yog ib qho nyuaj kom tau ib tug du thiab ci txheej txawm nyob rau hauv ib txwm ntau yam ntawm lub brightener; Thaum huab hwm coj concentration ntawm Cl - siab dhau lawm, nws yuav ua rau kom lub zog noj ntawm brightener. Ib feem ntawm qhov ci ci yog siv los ntawm kev suav nrog cov khoom ua haujlwm thiab cov txheej txheem hauv cov txheej txheem plating uas tau siv rau lub sijhawm ntev; Ib feem yuav decompose rau hauv cov organic impurities; Ib feem tseem nyob hauv cov tshuaj plating, ua rau muaj kev hloov pauv ntawm cov teeb pom kev zoo nws tus kheej. Cov xwm txheej no tuaj yeem cuam tshuam qhov ci ntsa iab ntawm cov txheej txheej thiab ua rau muaj qhov tsis xws luag hauv txheej txheej. Ntxiv nrog rau kev siv lub teeb ci raws li cov neeg siv phau ntawv siv hauv kev tsim khoom, nws tseem yuav tsum tau siv zog ua kom pom tseeb ntawm kev siv lub teeb ci, thiab xyuam xim rau kev sib sau ntawm kev paub thiab kev soj ntsuam kom zoo. Cov txheej txheem ntawm kev ntxiv tsawg thiab ntau brighteners nyob rau hauv raws sij hawm yog saws kom lub brightener tas li nyob rau hauv lub plating tov. Tsis tas li ntawd, qhov kub thiab txias ntawm cov tshuaj plating thiab cov nqi hluav taws xob siv tau muaj kev cuam tshuam loj heev rau kev noj cov brighteners. Yog tias qhov tam sim no siab thiab lub sij hawm ntev, kev noj cov brightener yuav siab; Ntawm qhov tsis sib xws, kev noj cov brighteners txo. Qhov ntsuas kub zoo tshaj plaws rau feem ntau cov ci ci siv hauv acidic tooj liab plating yog nyob nruab nrab ntawm 10 thiab 35 degree. Nws yog ib qho tsim nyog los xaiv qhov tsim nyog cathodic tam sim no ceev raws li qhov kub ntawm plating thiab qhov loj ntawm cov electrolyte, txwv tsis pub cov txheej yuav tsis ci. Zoo li ib qho kev ci ntsa iab, thaum lub plating tov kub tshaj 38 degree, qhov ci ci tau nrawm, thiab qhov ci ci ntawm cov txheej yuav nqaim. Tsuas yog los ntawm kev siv lub dav kub acidic tooj liab plating brightener tuaj yeem ua rau da dej kub nce mus txog 40 degree, thiab cov xim tooj liab ci tseem tuaj yeem tau txais nyob rau hauv qhov chaw qis tam sim no.
