Kev soj ntsuam ntawm kev ua haujlwm tsis zoo hauv potassium chloride zinc plating ntawm hluav taws xob cua sov raj

Potassium chloride zinc plating yog ammonium tsis muaj zog acidic ci zinc plating txheej txheem tsim los ntawm qhov ntxov tshaj cyanide dawb ammonium chloride plating tov. Nws qhov zoo yog: (1) zoo conductivity ntawm cov tshuaj plating, tsis tshua muaj tank siab, thiab txuag hluav taws xob; (2) Cov txheej yog finely crystallized, ci, thiab tiaj tus; (3) High tam sim no efficiency thiab ceev deposition ceev; (4) Cov tshuaj plating muaj peev xwm dispersion zoo; (5) Haum rau kev ncaj qha electroplating ntawm castings; (6) Kev kho dej khib nyiab yooj yim thiab daws teeb meem ntawm ib puag ncig muaj kuab paug. Yog li ntawd, potassium chloride zinc plating tau siv dav hauv kev lag luam.

Txawm li cas los xij, qhov ua tsis tau zoo yog qhov tsis muaj txiaj ntsig hauv kev tsim khoom txhua hnub, feem ntau yog vim kev saib xyuas tsis zoo ntawm cov txheej txheem plating, cov khoom tsis sib xws lossis cuam tshuam los ntawm cov teeb meem tsis zoo, nrog rau kev kho tsis zoo ua ntej ntawm lub workpiece. Kab lus no yog lub hom phiaj los piav qhia thiab qhia txog cov laj thawj thiab kev kho mob ntawm kev ua txhaum ntawm cov tshuaj potassium chloride zinc plating.

2. Qhov ua rau thiab tuav txoj kev ntawm ntau yam kev ua txhaum

2.1 Cov txheej tsis ci

2.1.1 Ua rau

(1) Plating kua concentration tsawg dhau (xws li cov ntsiab lus ntawm zinc chloride, potassium chloride, thiab boric acid yog tsawg);

(2) Tsis txaus brightener;

(3) Ntau dhau pH;

(4) Lub plating tov kub siab dhau lawm;

(5) Tsawg cathode tam sim no ceev;

(6) Muaj ntau yam impurities hauv cov hlau hlau;

(7) Muaj ntau cov organic impurities.

2.1.2 Cov txheej txheem ua

(1) Los ntawm kev txheeb xyuas, ntxiv zinc chloride, potassium chloride, thiab boric acid rau cov txheej txheem tshwj xeeb;

(2) Ntxiv brighteners kom tsim nyog;

(3) Kho cov pH rau cov txheej txheem tshwj xeeb siv cov tshuaj dilute hydrochloric acid;

(4) Txo qhov kub ntawm cov tshuaj plating rau cov txheej txheem specifications;

(5) Ua kom cov cathode tam sim no ntom ntom;

(6) Ntxiv 0. thiab lim kom tshem tawm cov hlau hydroxide;

(7) Ntxiv 1-3 g/L activated carbon ntawm lub plating tov kub ntawm 45 degree C, do rau li 30 feeb, thiab lim; Xwb, txoj kev poov tshuaj permanganate tuaj yeem siv rau kev kho mob, uas yog thawj zaug txo qis pH mus rau 3 nrog dilute hydrochloric acid ~

4. Tom qab ntawd, thaum nplawm, ntxiv dej kub yaj hauv 0 5-1g/L poov tshuaj permanganate tusyees mus rau lub plating tov, ntxiv stirring rau 30 feeb, thiab ces cia nws sawv ntsug rau pom kom tshem tawm cov organic. teeb meem.

2.2 Misting thiab blooming

2.2.1 Ua rau

(1) Lub plating tov kub siab dhau lawm; Kev daws teeb meem ntawm potassium chloride zinc plating

(2) Ntau dhau pH;

(3) Ntau plating ntawm workpieces los yog tsis txaus anode cheeb tsam;

(4) Cov ntsiab lus zinc chloride tsawg dhau;

(5) Muaj ntau yam impurities hauv hlau tooj liab thiab txhuas;

(6) Tsis txaus brightener;

(7) Ntau cov organic impurities;

(8) Kev kho tsis zoo ua ntej ntawm qhov chaw ntawm lub workpiece substrate.

2.2.2 Txoj kev ua

(1) Txo lub plating tov kub rau cov txheej txheem specification;

(2) Kho cov pH rau cov txheej txheem tshwj xeeb;

(3) Txo lub peev xwm thauj khoom ntawm qhov chaw ua haujlwm kom tsim nyog lossis nce thaj tsam ntawm anode zinc phaj;

(4) Los ntawm kev txheeb xyuas, ntxiv zinc chloride rau cov txheej txheem tshwj xeeb;

(5) Siv txoj kev tshem tawm (ntxiv 1-3 g ntawm cov hmoov zinc ntshiab) los yog cov khoom siv hluav taws xob tsawg tam sim no kom tshem tawm cov tooj liab thiab cov hlau lead impurities (ntau cov tooj liab thiab txhuas cov ntsiab lus tseem tuaj yeem ua rau cov txheej hauv qhov chaw ntom ntom tam sim no kom pom cov xim dub. huab cua);

(6) Ntxiv brighteners kom tsim nyog;
