Txoj kev electroplated rwb thaiv tsev muaj ntau. Qhov yooj yim tshaj yog sib tshooj ntawm cov khoom uas tsis yog plated ntawm tib qho nrog sib, thiab kom pom tsuas yog qhov uas xav tau electroplating. Qhov tseeb, txhuam plating thiab bipolar plating kuj yog rau cov uas muaj cov plating ib nrab. Tshooj lus no qhia txog kev rwb thaiv tsev siv ib nrab rwb thaiv rau ib nrab plating.
Txoj kev no yuav tsum tau hais tias cov khoom yuav tsum tau plated thiab cov khoom uas tsis yog plated muaj qhov zoo li ciam teb kom lub txheej txheem thaiv tsev yuav raug muab kho thiab muaj tseeb thiab zoo nkauj ciam teb tau. Cov ntaub ntawv pov thaiv cov txheej txheem thiab cov substrate yuav tsum muaj qee qhov sib thooj, thiab muaj peev xwm tiv cov kua qaub thiab alkali, kub, yooj yim hloov tom qab txheej, yooj yim tshem tawm tom qab plating, tsis paug cov tshuaj. Feem ntau siv kev rwb thaiv tsev yog:
1. Encapsulation
Hom no yog siv cov yeeb yaj kiab zaj duab xis, tapes, yas yas, roj hmab plugs, pawm thiab lwm cov khoom siv thaag rau qhwv thiab thaiv cov khoom uas tsis yog khoom. Yog hais tias lub qhov tsis yog plated, qhov yuav ua tau ntawm cov yas yas uas me me loj dua lub puab inch, los yog siv rau roj hmab. Plug lossis ncoo kom nruj ob hnub; peripheral uas tsis yog plated, yuav ua tau me ntsis me tshaj ntawm txoj kab uas hla ntawm lub raj yas tom qab kub txheej, tuaj yeem siv rau bandage. Txoj kev no yooj yim thiab yooj yim. Qhov tsis zoo yog tias cov khoom siv nrog txoj kab tsis yoojyim yuav tsum muab qhwv, thiab txoj kev sib txuas ntawm cov pob qij txha yog qhov yooj yim los ntxuav, uas yooj yim ua rau kev sib nraus ntawm kev daws teeb meem.
2. Cov txheej txheem thaiv tsev
(1) Npaj kev npaj. Rwb thaiv tsev nrog cov ciab yog qhov zoo ntawm kev nplua ntawm cov txheej thaiv tsev thiab cov tsho lub cev, thiab qhov kawg ntawm qhov tsis tuaj yeem siv hlais thaum siv, thiab tsim nyog rau qhov chaw uas muaj kev siab dav siab yuav tsum ua kom tiav ntawm qhov rwb thaiv tsev. Tsis tas li ntawd, cov tshuaj formulations tau muab coj mus ua dua tshiab. Qee lub cev muaj cwj pwm yog tshwm nyob rau hauv Table 2-4-9.
Formulations 1 thiab 2 yog tsim rau da dej nrog kev kub ua haujlwm hauv qab 40 ° C thiab siv rau galvanizing, cadmium, tooj liab, xee tes, nyiaj, hmoov txhuas txhuas, thiab lwm yam, thiab kev rwb thaiv tsev ntawm qhov chaw sov los yog kub kub anodized qhov chaw. Formula 3 yog tsim rau chrome plating ntawm kev kub hauj lwm ntawm 40 ° C mus rau 60 ° C thiab rwb thaiv tsev ntawm cov khoom noj uas yooj yim thiab cov tawv nqaij nyuaj nrog oxalic acid thiab sulfuric acid.
