Electroplating yog ib qho txheej txheem zoo kawg nkaus uas tau siv rau ntau pua xyoo los txhim kho qhov zoo nkauj thiab ruaj khov ntawm ntau yam khoom, tshwj xeeb tshaj yog cov hniav nyiaj hniav kub. Cov txheej txheem no cuam tshuam nrog kev tso ib txheej hlau rau ntawm qhov chaw los ntawm kev tshuaj ntsuam electrochemical. Ib qho ntawm cov khoom tseem ceeb hauv cov txheej txheem yog lub electroplating rectifier, uas ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj txiaj ntsig zoo thiab zoo ntawm kev ua haujlwm electroplating. Hauv tsab xov xwm no, peb yuav tshawb nrhiav seb nws siv sijhawm ntev npaum li cas los electroplate hniav nyiaj hniav kub thiab qhov tseem ceeb ntawm electroplating rectifier hauv lub sijhawm no.
Cov txheej txheem electroplating
Ua ntej peb yuav tham txog seb yuav siv sijhawm ntev npaum li cas los ua electroplate cov hniav nyiaj hniav kub, nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem electroplating nws tus kheej. Cov txheej txheem pib nrog kev npaj cov hniav nyiaj hniav kub, uas feem ntau suav nrog kev ntxuav thiab polishing kom tshem tawm cov av qias neeg, roj, lossis oxides. Cov kauj ruam no yog qhov tseem ceeb vim tias txhua yam khoom tsis huv tuaj yeem cuam tshuam rau qhov lo ntawm cov hlau.
Thaum cov hniav nyiaj hniav kub npaj txhij lawm, nws yuav raug muab tso rau hauv cov kua electrolyte uas muaj cov hlau ions. Cov hniav nyiaj hniav kub ua haujlwm ua cathode (negative electrode) hauv lub voj voog electroplating, thaum lub anode (positive electrode) feem ntau yog ua los ntawm cov hlau uas yuav raug tso rau hauv. Thaum muaj hluav taws xob hla dhau cov kua, cov hlau ions raug txo thiab tso rau ntawm qhov chaw ntawm cov hniav nyiaj hniav kub, tsim ib txheej hlau nyias nyias.
Cov yam tseem ceeb uas cuam tshuam rau lub sijhawm electroplating
Lub sijhawm uas yuav tsum tau siv electroplate cov hniav nyiaj hniav kub sib txawv heev nyob ntawm ntau yam:
1. Qhov Tuab Txheej: Qhov tuab ntawm cov hlau txheej uas xav tau yog ib qho ntawm cov yam tseem ceeb uas txiav txim siab lub sijhawm electroplating. Cov txheej tuab dua yuav tsum siv sijhawm ntau dua los ua kom tiav, thaum cov txheej nyias dua tuaj yeem ua tiav sai dua.
2. Hom Hlau: Cov hlau sib txawv tso rau ntawm cov nqi sib txawv. Piv txwv li, kub thiab nyiaj yuav siv sijhawm tsawg dua los tso dua li cov hlau hnyav xws li nickel lossis tooj liab.
3. Qhov Ceev Tam Sim No: Qhov ntau ntawm cov tam sim no siv thaum lub sijhawm electroplating cuam tshuam rau qhov nrawm ntawm kev tso dej. Qhov ceev tam sim no siab dua tuaj yeem ua rau cov txheej txheem electroplating sai dua, tab sis nws kuj tseem tuaj yeem ua rau tsis zoo yog tias tsis tswj hwm kom zoo.
4. Kub ntawm cov electrolyte: Qhov kub ntawm cov electrolyte cuam tshuam rau qhov ceev ntawm cov txheej txheem electroplating. Qhov kub ntawm cov tshuaj ntau dua, qhov ceev ntawm kev tso dej.
5. Qhov zoo ntawm lub rectifier electroplating: Lub rectifier electroplating yog ib qho tseem ceeb uas hloov cov hluav taws xob hloov pauv (AC) mus rau cov hluav taws xob ncaj qha (DC) rau kev siv hauv cov txheej txheem electroplating. Lub rectifier zoo ua kom muaj hluav taws xob ruaj khov thiab sib xws, uas yog qhov tseem ceeb rau kev ua tiav electroplating sib xws. Yog tias lub rectifier tsis ua haujlwm zoo, nws yuav ua rau muaj kev hloov pauv tam sim no, cuam tshuam rau qhov nrawm ntawm kev tso dej thiab qhov zoo ntawm electroplating.
Lub Sijhawm Ib Txwm Muaj Rau Electroplating Hniav Nyiaj Hniav Kub
Xav txog cov yam saum toj no, lub sijhawm uas yuav tsum tau siv electroplate cov hniav nyiaj hniav kub yuav txawv ntawm ob peb feeb mus rau ob peb teev. Piv txwv li:
Kev Siv Hluav Taws Xob Me Me: Yog tias koj xav siv ib txheej kub lossis nyiaj nyias nyias rau kev kho kom zoo nkauj, cov txheej txheem no yuav siv sijhawm 10 txog 30 feeb. Qhov no feem ntau txaus rau cov hniav nyiaj hniav kub lossis cov hniav nyiaj hniav kub uas tsis tshua hnav.
Kev Plating Nruab Nrab: Yuav kom ua tiav qhov tiav uas ruaj khov dua, xws li txheej kub lossis nickel tuab dua, cov txheej txheem plating yuav siv sijhawm txij li 30 feeb txog 2 teev. Lub sijhawm no yuav tsim cov txheej txheej uas ruaj khov dua uas tuaj yeem tiv taus kev hnav thiab rhuav txhua hnub.
Kev Sib Tov Tuab: Thaum xav tau tuab dua, xws li rau kev siv hauv kev lag luam lossis cov hniav nyiaj hniav kub zoo, cov txheej txheem tuaj yeem siv sijhawm ntau teev. Qhov no yog qhov tseeb tshwj xeeb rau cov khoom uas yuav tsum tau tiv taus cov xwm txheej hnyav lossis siv ntau zaus.
Qhov Tseem Ceeb ntawm Kev Tswj Xyuas Zoo
Txawm siv sijhawm ntau npaum li cas los xij, kev tswj xyuas qhov zoo yog qhov tseem ceeb hauv cov txheej txheem electroplating. Kev siv lub rectifier electroplating txhim khu kev qha yog qhov tseem ceeb kom tswj tau qhov ntws tam sim no tas li, uas cuam tshuam ncaj qha rau qhov zoo ntawm cov txheej plated. Qhov tam sim no tsis sib xws tuaj yeem ua rau cov plating tsis sib xws, tsis nplaum zoo thiab txawm tias muaj qhov tsis zoo xws li pitting lossis blistering.
Tsis tas li ntawd xwb, kev saib xyuas thiab kev kho kom zoo ntawm lub rectifier electroplating tsis tu ncua yog qhov tsim nyog kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws. Qhov no suav nrog kev kuaj xyuas cov cim ntawm kev hnav lossis kev ua tsis tiav thiab hloov cov khoom raws li qhov tsim nyog.
Hauv kev xaus, lub sijhawm uas yuav tsum tau siv los electroplate cov hniav nyiaj hniav kub tuaj yeem sib txawv ntau nyob ntawm ntau yam, suav nrog qhov tuab ntawm cov txheej txheem xav tau, hom hlau siv, thiab qhov zoo ntawm lub plating rectifier. Txawm hais tias lub teeb plating tsuas yog siv ob peb feeb xwb, cov ntawv thov dav dua tuaj yeem txuas ntxiv cov txheej txheem mus rau ntau teev. Kev nkag siab txog cov kev hloov pauv no yog qhov tseem ceeb rau cov kws ua hniav nyiaj hniav kub thiab cov neeg nyiam ua si, vim nws tso cai rau kev npaj zoo dua thiab kev ua tiav ntawm cov txheej txheem electroplating. Los ntawm kev ua kom ntseeg tau tias lub plating rectifier zoo siv thiab tswj hwm hauv cov xwm txheej zoo, ib tus tuaj yeem ua tiav cov hniav nyiaj hniav kub zoo nkauj, ruaj khov uas yuav sawv ntawm qhov kev xeem ntawm lub sijhawm.
