Cov teebmeem ntawm plating daws kev ruaj ntseg thiab kev sib pauv hluav taws xob muaj peev xwm ntawm electroplating hluav taws xob cua sov kav

① Cua sov lossis cua txias. Txij li thaum cov tshuaj electroplating yuav tsum tau ua haujlwm ntawm qhov kub thiab txias, nws yog ib qho tsim nyog yuav tsum tau nruab lub plating tank nrog lub tshuab cua sov. Piv txwv li, qhov kub ntawm cov plating tov rau ci npib tsib xee plating yuav tsum tau khaws cia ntawm 50 degree, qhov kub yuav tsum tau rau chrome plating yog 50 mus rau 60 degree, thiab cov kua qaub ci tooj liab plating los yog ci nyiaj plating kuj yuav tsum tau qhov kub thiab txias nyob rau hauv. 30 degree. Yog li, cov txheej txheem no yuav tsum tau ua kom tau raws li cov khoom siv hluav taws xob sib pauv. Rau cua sov, cua sov ncaj qha feem ntau yog siv, uas yog, stainless hlau los yog titanium hluav taws xob cua sov raj yog siv ncaj qha mus rau hauv lub plating tank, thiab ib co yog fixedly ntsia nyob rau hauv lub tank ntug los yog tank hauv qab uas tsis cuam tshuam rau lub plating ua hauj lwm. Rau qhov loj dua corrosion ntawm da dej, nws yog qhov zoo tshaj plaws los siv PTFE-tswj hluav taws xob rhaub. Qee lub tsev lag luam tseem siv chav rau cua sov tsis ncaj.

Muaj cov txheej txheem cua txias ncaj qha thiab cov txheej txheem cua txias. Hauv cov chav tsev uas tsis muaj cov xwm txheej los txhim kho lub txias txias, cov dej khov nab kuab yog siv los ua kom txias, thiab cov dej khov nab kuab tau muab tso rau ntawm lub tank plating. Qhov no yog qhov chaw kawg. Rau plating cov noob uas yuav tsum tau txias, yuav tsum tau siv lub txias txias. Cov hlab ntawm lub exchanger yuav tsum tau ua los ntawm tib yam khoom raws li cov cua kub raj uas muaj peev xwm tiv taus corrosion los ntawm cov tshuaj plating.

② Cathode txav los yog nplawm ntaus ntawv. Qee hom plating lossis feem ntau ntawm cov plating xav tau cov cathode nyob rau hauv lub xeev viav vias, uas tuaj yeem ua rau cov haujlwm ua haujlwm tam sim no, ua rau cov txheej txheem plating ua nws lub luag haujlwm (feem ntau ci ntsa iab thiab tawg muaj peev xwm), thiab tiv thaiv cov npoo ntse thiab cov fab. Coated, hlawv.

Piv txwv li, feem ntau ci plating hom, xws li ci nickel plating, acid ci tooj liab plating, thiab ci nyiaj plating, yuav tsum tau cathode txav. Cathode txav kuj yog cov khoom siv tsis yog qauv, tsuav yog tias cov cathode tuaj yeem ua cov kab rov tav lossis ntsug reciprocating kev sib hloov ntawm cov cuab yeej siv tshuab, tuaj yeem siv los ua cov khoom txav cathode. Lub amplitude thiab zaus ntawm kev txav mus los feem ntau yuav tsum yog l0 txog 20 zaug hauv ib feeb, thiab txhua qhov stroke feem ntau yog 10 mus rau 20 cm raws li qhov ntev ntawm lub plating tank. Qee cov noob plating tuaj yeem siv tshuab lossis cua agitation es tsis txhob cathode txav. Cov neeg kho tshuab nplawm yog nqa tawm nrog lub tov khoom ua los ntawm cov khoom siv corrosion-resistant, feem ntau yog tsav los ntawm lub cev muaj zog, tab sis qhov ceev yuav tsum tsis txhob siab dhau. Huab cua agitation siv compressed cua uas tau raug lim kom tshem tawm cov roj paug.

1. Cov txheej txheej saum npoo ua tau raws li qhov yuav tsum tau ua, ci ntsa iab, thiab tsis muaj xim sib txawv ntawm cov khoom siv tib yam (Ceeb toom: xim sib txawv suav nrog xim thiab gloss);

2. Qhov saum npoo ntawm cov txheej txheej electroplating yog tus du, qhov saum npoo tom qab electroplating yuav tsum tiaj tus thiab tsis sib xws, thiab electroplated nto yuav tsum tsis muaj qhov tsis xws luag:

① Foaming phenomenon: Qhov saum npoo ntawm txheej thiab lub substrate yog ib feem ntawm tev tawm, ua rau muaj qhov tshwm sim npuas;

② Peeling tshwm sim: txheej thiab substrate yog tev tawm; txheej yog cais los ntawm cov khoom siv substrate hauv flakes

③ Cov kab hluav taws kub hnyiab: xim tsaus, roughness, xoob tawg thiab lwm yam khoom tsis zoo uas tsim nyob rau hauv siab tam sim no, uas feem ntau muaj oxides lossis lwm yam impurities.

④ Peeling kab: Cov txheej txheej electroplating ntawm cov khoom tawg los yog yooj yim poob vim qee qhov laj thawj (xws li tsis sib xws thermal expansion lossis shrinkage).

⑤ Pockmarking phenomenon: qhov me me los yog qhov tsim ntawm cov hlau nto thaum lub sij hawm electroplating txheej txheem los yog corrosion

⑥ Roughness: Thaum lub sij hawm electroplating txheej txheem, txheej yog ntxhib thiab tsis du vim ntau yam laj thawj.

⑦ Cov kab dej tsis zoo, cov xim xim: feem ntau yog siv rau qhov tsis sib xws ntawm kev ntub dej los ntawm qhov chaw paug, ua rau cov yeeb yaj kiab dej ntawm qhov chaw tsis tu ncua.

⑦ Plua plav xim: Hloov xim ntawm cov hlau los yog txheej txheej los ntawm corrosion (xws li darkening, poob xim, thiab lwm yam).
