Kev saib xyuas ntawm nickel plating tank

Kev saib xyuas ntawm nickel plating tank

1) Khaws qhov kub ntawm 55-60qC, thiab qhov kub ntawm pre plating thiab semi gloss npib tsib xee yuav tsum tsis txhob siab tshaj 65 degrees Celsius kom tsis txhob darkening ntawm cov xim txheej.

2) Txheeb xyuas tus nqi pH ntawm cov tshuaj plating ob zaug hauv ib hnub thiab tswj nws ntawm 4.0 thiab 4.2. Thaum tus nqi pH siab dhau lawm, dilute H2SO4 (kwv yees li 30 feem pua) yog siv los kho nws, thiab thaum tus nqi pH qis dhau, dilute NaOH (li 10 feem pua) yog siv los kho nws.

3) Siv sijhawm ntxuav cov khoom siv crystalline hauv cov tshuaj plating raws ntug ntawm lub da dej kom tsis txhob muaj ntau dhau thiab poob rau hauv da dej ua rau muaj qhov tsis xws luag xws li burrs thiab pits ntawm txheej plating.

4) Rau cov nickel tso tsheb hlau luam, qhov pom ntawm cov tshuaj plating yog qhov tseem ceeb heev, thiab cov nyhuv pom yuav tsum zoo dua. Absorb carbon tsawg kawg ib zaug ib lub lim tiam, nrog cov pa roj carbon absorption ntawm 0.2 ~ 0.5k.g/1000L.

5) Lub tank ua ntej nickel plating yuav tsum tau muab xa mus rau txhua peb lub hlis, lub hnab anode yuav tsum tau ntxuav, lub hnab ntim anode yuav tsum tau kuaj xyuas thiab hloov, thiab cov tshuaj plating yuav tsum tau kho ib zaug txhua rau lub hlis. Semigloss nickel thiab tag nrho-gloss npib tsib xee yuav tsum tau muab tso rau txhua txhua rau lub hlis, ntxuav thiab hloov nrog cov hnab looj anode hnav, thiab kho dua tshiab tsawg kawg ib xyoos ib zaug.

6) Thaum lub sij hawm tsis ua hauj lwm, me me tam sim no electrolysis ({1}}.2 ~ 0.5A / dm) yuav tsum tau ua nyob rau hauv lub plating tov kom tshem tawm cov hlau impurities.

7) Xyuas cov hluav taws xob conductivity ntawm txhua qhov kom ntseeg tau tias hluav taws xob conductivity zoo.

8) Ua ib qho Hall cell test piece ntawm lub plating da dej txhua ob hnub kom nkag siab txog cov xwm txheej ntawm cov tshuaj plating. Txheeb xyuas qhov muaj pes tsawg leeg ntawm cov tshuaj plating ib zaug ib lub lim tiam thiab ntxiv cov ntaub ntawv hauv lub sijhawm.

9) Zinc impurities yog yooj yim nqa nyob rau hauv pre nickel plating tso tsheb hlau luam, thiab ib tug tej yam nqi ntawm impurity tshem tawm dej feem ntau yuav tsum tau los tswj cov kev puas tsuaj ntawm zinc ions rau electroplating. Thaum xaiv, yuav tsum tau them nyiaj rau kev xaiv impurities tshem tawm cov dej uas tsis muaj leej faj, vim hais tias ntxiv impurities tshem tawm cov dej uas muaj leej faj cov ntsiab lus yuav yooj yim ua npuas ntawm pre plating npib tsib xee thiab acid tooj liab.
