Nyuaj chromium plating ntawm chromium hais txog qhov luaj li cas ntawm cov khoom tsis tau raws li cov txheej txheem ntawm tus txheej txheem tsim, los yog vim hnav thiab rhuav los ntawm qhov sib txawv me ntsis, xav tau chromium plating rau puag txheej thiab ces kho ib co thickness ntawm chromium txheej . Cov txheej txheem ntawm chromium plating ntawm chromium yog cov nyuab dua li ntawm cov chromium plating ntawm cov ntaub ntawv luj. Vim hais tias qee qhov chaw tsuas yog plated, qee qhov muab tso rau ntev, qee qhov tau ua tiav thiab txhuam hniav. Lub ntsiab yog vim tias qhov chaw ntawm lub chromium txheej yog ib qho yooj yim rau tsim cov khoom cua hauv cov huab cua. Lub neej ntawm zaj dab neeg txog kev hla no cuam tshuam txog lub zog ntawm lub txheej thiab lub hauv paus hlau thaum lub sijhawm thib ob chromium plating. Tsuas yog tus sau zaj duab xis tawm xwb, qhov txheej yuav tsum tau. Chromium plating thiaj li ua tau zoo ua ke ntawm tag nrho cov txheej, qhov tseem ceeb ua ntej kev kho plating thiab kev ua kom deg.
Skim. Tshem tawm cov roj ntawm cov nplais ntawm cov khoom siv los ntawm cov pa qauv. Tom qab muab polishing, polishing thiab siv cov roj hnyav rau ib lub sijhawm, hnyav dua, xws li roj thiab txhuam hniav, tseem ceeb heev.
Sib tsoo. Lub burr nyob rau saum npoo ntawm chrome plating txheej yuav tsum tau polished los ntawm whetstone; qee qhov chaw yuav them nrog chromate zaj duab xis thiab li ntawm vim yog lub sij hawm ntev dua uas lawv muab tso rau. Nws tsis yog yooj yim tshem tawm nrog txoj kev dav dav thiab xav tau kom zoo zoo nrog polished.
Preheating. Tom qab qhov chaw raug dai hauv qhov zawj, lub sijhawm ua ntej yuav raug xaiv raws li qhov luaj li cas, thiaj li txo qhov sib txawv ntawm qhov chaw thiab cov chromium plating kua, thiab tsis txhob muaj qhov xwm txheej ntawm daim tawv nqaij poob thiab tev tawm vim ntawm cov coefficient expansion ntawm lub hauv paus thiab cov txheej chromium. Cov kauj ruam no tseem ceeb dua rau cov chrome plated qhov chaw.
Anode kho mob. Muaj ib txheej ntawm chromium nyob rau ntawm qhov chaw, thiab txoj kev kho tus mob anode yog ua kom lub ntsej muag ntau ntxhib thiab nce lub zog ntawm tsevneeg. Lub sij hawm ntawm anodic kev kho mob yuav tsum tau txiav txim siab raws li lub thickness ntawm tus uas twb muaj lawm chromium txheej. Lub txheej yog ob peb xe nkoos, thiab qhov txheej yog thicker, mus txog 2 ~ 3min.
Plated Normal. Qhov qhib rua ntawm chromium txheej yog kauj ruam tam sim no yog lub kauj ruam tseem ceeb tshaj plaws nyob rau hauv tag nrho cov txheej txheem cladding. Siv thawj zaug 5A / DM2 tam sim no ceev ceev 3 ~ 5min, thiab tom qab ntawd 10 ~ 15min lub sij hawm, qhov ceev ceev tam sim no nce mus rau 20 ~ 25A / DM2 ntawm, nyob rau hauv qhov tam sim no ntom nti plating, thiab thaum kawg rau hauv lub cev electroplating.
