Ntawm ntau yam thev naus laus zis uas txhim kho kev ntim khoom, electroplating sawv tawm. Nws tsis tsuas yog ua rau lub ntim khoom zoo nkauj, zoo nkauj xwb, tab sis kuj muaj ntau yam zoo.
Cov Txheej Txheem Electroplating yog dab tsi?
Electroplating yog plating ntawm ib lossis ntau txheej hlau rau ntawm qhov chaw ntawm ib qho workpiece los ntawm kev siv electrodeposition, muab qhov workpiece zoo nkauj lossis cov kev xav tau ua haujlwm tshwj xeeb. Hauv electroplating, cov hlau plated lossis lwm yam khoom siv tsis yaj yog siv ua anode, thiab cov khoom hlau uas yuav tsum tau plated yog siv ua cathode, thiab cov cations ntawm cov hlau plated raug txo rau ntawm qhov chaw hlau los tsim cov txheej plated. Txhawm rau tshem tawm kev cuam tshuam ntawm lwm cov cations thiab ua kom cov txheej plating sib xws thiab ruaj khov, nws yog qhov tsim nyog siv cov tshuaj uas muaj cov cations ntawm cov hlau plating ua cov tshuaj plating kom khaws qhov concentration ntawm cov cations ntawm cov hlau plating tsis hloov pauv. Lub hom phiaj ntawm electroplating yog hloov cov khoom ntawm qhov chaw lossis qhov ntev ntawm lub substrate los ntawm kev siv cov hlau txheej rau lub substrate. Electroplating txhim kho qhov tsis kam ntawm cov hlau (cov hlau plated feem ntau yog corrosion-resistant), nce hardness, tiv thaiv kev puas tsuaj, thiab txhim kho kev coj hluav taws xob, lubricity, tiv thaiv cua sov, thiab qhov zoo nkauj ntawm qhov chaw.
Txheej Txheem Plating
Kev kho ua ntej (kev sib tsoo → kev npaj ntxuav → kev ntxuav dej → kev ntxuav roj electrolytic → kev ntxuav dej → kev ua kom cov kua qaub thiab kev ua kom muaj zog → kev ntxuav dej) → kev ua kom tsis muaj zog → kev ntxuav dej → kev plating (priming) → kev ntxuav dej → kev ua kom tsis muaj zog → kev ntxuav dej → kev plating (txheej saum npoo) → kev ntxuav dej → dej ntshiab → kev ua kom qhuav → kev ziab
Cov txiaj ntsig ntawm electroplating rau cov tshuaj pleev ib ce
Kev zoo nkauj zoo dua
Kev siv hluav taws xob electroplating muaj peev xwm ua kom lub thawv tshuaj pleev ib ce zoo nkauj dua tam sim ntawd. Cov xim xws li kub, nyiaj lossis chrome tuaj yeem hloov lub thawv ib txwm mus ua lub cim ntawm kev nplua nuj. Piv txwv li, ib lub hmoov compact plated kub liab zoo nkauj ua rau muaj kev xav zoo nkauj uas nyiam cov neeg siv khoom uas nyiam qhov kev zoo nkauj no nrog cov khoom kim heev.
Kev Ruaj Khov thiab Kev Tiv Thaiv Zoo Dua
Ntxiv rau qhov zoo nkauj, kev plating ua rau lub ntim khoom zoo nkauj ruaj khov dua. Cov txheej hlau nyias no ua haujlwm ua lub zog tiv thaiv, tiv thaiv cov khoom hauv qab los ntawm kev puas tsuaj los ntawm kev xeb, khawb thiab tshuaj lom neeg. Qhov no tseem ceeb heev rau cov khoom uas siv thiab kov ntau zaus, xws li cov raj mis lipstick.
Kev txhawb nqa ntawm daim duab hom lag luam
Qhov zoo nkauj uas ua tiav los ntawm kev siv electroplating tuaj yeem ua rau lub npe nrov dua. Cov ntim khoom zoo nkauj ua rau pom qhov zoo thiab tshwj xeeb rau cov tshuaj pleev ib ce. Cov npe tuaj yeem xaiv cov xim plating thiab cov xim tiav uas phim lawv lub npe nrov, ua rau kev paub txog lub npe nrov thiab kev ntseeg siab ntawm cov neeg siv khoom.
Kev siv electroplating hauv kev ntim khoom tawv nqaij
Cov fwj tshuaj tsw qab
Feem ntau cov fwj tshuaj pleev ib ce muaj lub hau lossis lub npoo uas muaj hlau plated. Piv txwv li, lub fwj tshuaj pleev ib ce uas muaj lub hau chrome-plated tsis yog tsuas yog zoo nkauj thiab niaj hnub xwb, tab sis kuj muab lub foob zoo dua los tiv thaiv cov tshuaj pleev ib ce ntawm huab cua thiab cov pa phem. Cov hlau plated kuj tiv taus xeb los ntawm cov tshuaj hauv cov serum, ua kom ntseeg tau tias cov khoom siv tau ntev.
Cov Raj Mis Qab Zib
Cov thawv tshuaj pleev ntsej muag tej zaum yuav muaj lub hau plated. Lub hau kub plated ntawm lub thawv tshuaj pleev zoo nkauj tuaj yeem qhia tau tias muaj kev nplua nuj tam sim ntawd. Tsis tas li ntawd, cov hau plated tiv taus kev khawb thiab kev co ntau dua li cov hau tsis plated, ua kom lub thawv zoo nkauj txawm tias siv ntau zaus.
Cov Tshuab Muab Twj Tso Kua Mis
Kev plating kuj tseem siv rau hauv cov twj tso kua mis rau cov khoom siv saib xyuas tawv nqaij. Lub taub hau twj tso kua mis uas muaj nickel plated ua rau lub twj tso kua mis ruaj khov dua, ua rau nws tiv taus kev hnav thiab rhuav thaum siv ntau zaus. Qhov chaw du ntawm cov taub hau twj tso kua mis uas muaj plated kuj yooj yim dua los ntxuav, uas yog qhov tseem ceeb rau kev tswj kev huv thaum siv cov khoom siv saib xyuas tawv nqaij.
Kev plating yog qhov kho kom zoo nkauj ntawm "tus kws kho kom zoo nkauj", nws tuaj yeem ua rau lub substrate tau txais cov txheej txheem hlau zoo, zoo nkauj thiab tiv thaiv, nws cov khoom muaj nyob txhua qhov chaw, tsis hais qhov twg hauv thaj chaw, lossis hauv cov neeg cov zaub mov thiab khaub ncaws, vaj tse thiab kev thauj mus los uas tuaj yeem pom hauv cov txiaj ntsig plating ntawm qhov taw tes flash.
