1 theem: Tshem tawm ntawm txheej chromium
Ntawm cov ntawv thov tau ntawm cov thev naus laus zis no, kev sib tw ntawm cov tub sab nyiag tsheb tsheb, ob sab hauv, ntxig, discs yog daim ntawv thov lwm yam. Chromium muaj cov yeeb yaj kiab nyuaj, inert, oxide zaj duab xis uas tsim cov teeb meem uas muaj teeb meem nrog cov txheej txheem hluav taws xob hluav taws xob. Yog li ntawd, thawj theem ntawm cov txheej txheem yuav tshem cov txheej chromium. Rau lub hom phiaj no, siv cov "universal nqus". Nyob rau hauv cov txheej txheem tshem tawm cov txheej chromium, lub hav iav tau pleev xim rau hauv daj, uas yog thawj lub cim ntawm lub chrome-plated nto. Cov xim daj no yog chrome nyob rau hauv ntsev ntawm ib inorganic compound. Txhawm rau tshem tawm cov txheej chromium los ntawm cov cim tsheb, cov txheej txheem tuaj yeem siv sijhawm li ob peb feeb los ua lub tsheb Chrome li ib teev. Thaum ua tiav ntawm theem no ntawm cov txheej txheem, faib rau saum npoo ntawm ib feem distilled lossis de ionized dej.
Tom qab tshem tawm cov txheej chromium, qhov saum npoo ntawm ib feem muaj cov txheej daj ua rau muaj kev tiv thaiv kab mob plab - Qhov no yog cov khoom siv los tiv thaiv corrosion ntawm lub chrome txheej. Ua ntej nqa lub décor ntawm kub, nws yog ib qho tsim nyog yuav tsum qhib lossis decapping rau saum npoo ntawm ib feem. Rau lub hom phiaj no. Rau lub hom phiaj no, peb siv reagent reagent. Cov txheej txheem ua kom tiav nrog gilding yog siv rau microaling, kev tsim micro-grungs, kev tsim cov khoom siv oxesive ntawm cov khoom siv nplaum ntawm cov hlau nplaum. Thaum lub sij hawm ua kom lub zog ua kom tiav, cov xim ntawm lub tampon tsis hloov thiab cov tshuaj tiv thaiv yog nyuam qhuav pom. Txhawm rau nqa tawm cov txheej txheem no, nws txaus los siv ntau zaus nrog cov swipon moistened nyob rau hauv tus activator nyob rau saum npoo ntawm ib feem los txiav txim siab nws ua tiav. Tom qab cov txheej txheem no, yaug saum npoo nrog dej distilled lossis de ionized dej.
Tom qab cov txheej txheem ua kom ua kom tiav, npaj mus rau cov txheej txheem ntawm kev thov gilding. Peb siv rau lub hom phiaj no lub reagent "kub-ntws gel 24kt / 999 kuaj". Nyob rau hauv cov txheej txheem no, cov kub muaj nyob rau hauv cov gel hauv cov ntsev ntawm ib tug inorganic compound nyob rau hauv lub inrounded hlau nto, sib sau ib tug tsawg-ntxig me ntsis tense txheej ntawm nws txuam nrog nws ntawm qib molecular. Vim tias qhov zoo ntawm thev naus laus zis thiab siv, tshwj xeeb npaj cov gels loj, muaj lub siab muaj kev txhim kho sab nraud uas muaj cov gel nrog cov roj doping, muaj ob peb zaug Zog siab dua thiab hnav tsis kam piv nrog cov kub ua ntawv thov los ntawm lub tank electroplating.
