Vim nws zoo heev hluav taws xob conductivity thiab oxidation tsis kam, nyiaj plating yog dav siv nyob rau hauv cov txheej txheem kho deg rau hluav taws xob tiv tauj. Txawm li cas los xij, hauv kev tsim khoom tiag tiag, kev hloov pauv ntawm cov txheej txheem tswj hwm thiab ib puag ncig feem ntau ua rau muaj qhov tsis xws luag xws li tsis zoo adhesion, pinholes, blistering, thiab tsis sib xws plating deposition. Cov teeb meem no tuaj yeem cuam tshuam loj rau kev tiv thaiv kev tiv thaiv, hluav taws xob ruaj khov, thiab ntev - lub sij hawm kev ntseeg siab ntawm cov khoom tseem ceeb hauv relays, keyboards, thiab lwm yam hluav taws xob precision. Yog li ntawd, kev nkag siab tob txog ntau yam tsis xws luag-nrog rau cov txheej txheem hauv qab- ntsig txog qhov ua rau- yog qhov tseem ceeb rau kev txhim kho cov plating zoo ntawm kev sib cuag hluav taws xob thiab ua kom muaj kev ua tau zoo sib xws hauv siab - kev ntseeg siab ntawm hluav taws xob daim ntawv thov.
Cov txheej txheem electroplating feem ntau suav nrog cov theem tseem ceeb xws li pretreatment, electroplating deposition, thiab tom qab- kho. Ntawm cov no, pretreatment yog lub hauv paus kauj ruam uas txiav txim siab adhesion thiab stability ntawm plating txheej. Kev xyaum qhia tau hais tias ntau dua 80% ntawm electroplating defects tshwm sim los ntawm kev kho tsis raug, tshwj xeeb tshaj yog nyob rau hauv siab - cov khoom muaj tseeb xws li Silver Plated Contacts, qhov uas yuav tsum tau ua kom huv si saum npoo yog nruj dua.
Ib qho ntawm cov teeb meem tshwm sim nyob rau hauv lub pretreatment theem yog tsis tiav degreasing. Tej yam tshwm sim muaj xws li pinholes, blistering, thiab txawm lub zos tev ntawm txheej. Raws li kev soj ntsuam microscopic, cov roj suav nrog ntawm cov txheej thiab cov substrate feem ntau pom. Tsis tas li ntawd, kev ntsuam xyuas zaj duab xis dej muab qhov kev ntsuam xyuas pom ntawm qhov chaw; Cov yeeb yaj kiab uas tsis muaj dej tsis tu ncua lossis nrawm nrawm feem ntau qhia tias muaj cov kab mob sib kis. Hom teeb meem no yog tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov Silver-plated hluav taws xob tiv tauj, raws li txawm me me kis tau tus mob cuam tshuam rau conductivity.
Thaum lub sij hawm electroplating deposition theem, txheej defects kuj muaj ntau haiv neeg. Piv txwv li, cov coatings ntxhib, scorched, los yog glossy coatings feem ntau muaj feem xyuam rau cov tsis sib xws tam sim no faib los yog txawv txav plating tov muaj pes tsawg leeg. Hauv Silver plating rau cov txheej txheem kev sib cuag hluav taws xob, kev ruaj ntseg ntawm qhov tam sim no yog qhov tseem ceeb heev. Excessively high current densities can lead to excessively rapid localized deposition, resulting in a rough structure, while excessively low current densities may cause a porous coating, affecting conductivity.
Tsis tas li ntawd, cov ntsiab lus impurity hauv cov tshuaj plating ncaj qha cuam tshuam rau txheej zoo. Lub xub ntiag ntawm metallic impurities los yog organic paug nyob rau hauv cov kev daws yuav ua rau tsaus me ntsis los yog uneven deposition nyob rau saum npoo ntawm silver plated hu. Yog li ntawd, tsis tu ncua pom thiab tsom xam yog tsim nyog thaum lub sij hawm tsim cov txheej txheem, thiab kev daws purity yuav tsum tau khaws cia los ntawm activated carbon kho los yog electrolytic purification.
Tom qab{0}} kev kho mob tseem ceeb heev. Kev tu lossis ziab tsis txaus yuav ua rau cov tshuaj lom neeg nyob rau ntawm txheej txheej, ua rau muaj kev xeb los yog tsis muaj xim. Nyob rau hauv silver plated hu, nto stability ncaj qha cuam tshuam rau lub sij hawm ntev - conductivity ntawm cov khoom; Yog li ntawd, kev tu kom huv thiab kev tiv thaiv tsim nyog yuav tsum tau ua kom ntseeg tau.
Los ntawm kev xav ntawm tag nrho cov txheej txheem kev tswj hwm, tsim kom muaj kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb tshwj xeeb. Ua ntej, cov txheej txheem kev khiav hauj lwm yuav tsum tau tsim los tswj qhov kub thiab txias, lub sijhawm, thiab cov txheej txheem ntawm txhua qhov txheej txheem. Qhov thib ob, cov txheej txheem traceability yuav tsum ua tiav los ntawm kev saib xyuas online thiab sau cov ntaub ntawv. Thib peb, kev saib xyuas cov cuab yeej siv thiab kev cob qhia cov neeg ua haujlwm yuav tsum tau ntxiv dag zog kom ntseeg tau tias muaj kev sib luag hauv kev ua tiav.
Nyob rau hauv lub tshav pob ntawm kev sib cuag, cov kev xav tau rau plating zoo nyob rau hauv electroplated nyiaj hu yog deb tshaj cov zoo tib yam zoo nkauj electroplating. Yog li ntawd, cov tuam txhab yuav tsum tau nqis peev tsis tu ncua hauv kev tswj cov txheej txheem, kev tshuaj xyuas zoo, thiab kev hloov kho khoom siv kom tau raws li qhov xav tau ntawm cov ntawv thov siab - kawg.
Zuag qhia tag nrho, thaum cov txheej txheem electroplating yog qhov paub tab, nws txoj haujlwm ruaj khov yog nyob ntawm kev tswj hwm ntawm ntau yam. Los ntawm pretreatment mus rau deposition mus post-kev kho mob, txhua kauj ruam yuav tsum tau ceev faj tswj. Los ntawm kev txheeb xyuas cov teeb meem zoo sib xws thiab ua raws li kev ntsuas kev txhim kho, tag nrho cov txiaj ntsig zoo thiab kev sib raug zoo ntawm cov nyiaj sib raug zoo tuaj yeem txhim kho tau zoo, yog li ua tau raws li cov qauv siab xav tau hauv cov khoom siv hluav taws xob, hluav taws xob, thiab kev lag luam precision.
Cov lus nug nquag
1. Vim li cas cov nyiaj plating txheej ntawm Plating rau Kev Sib Txuas Hluav Taws Xob qee zaum pom qhov tsis zoo los yog tev tawm?
Cov adhesion tsis zoo yog feem ntau cuam tshuam nrog kev ua kom tsis txaus thaum ua ntej - kho, oxidation ntawm lub hauv paus hlau, los yog tsis ruaj tsis khov plating. Additionally, if the current density is excessively high or the internal stress within the plating layer is too great, it can cause the coating to peel or flake under thermal cycling or mechanical stress.
2. Dab tsi ua rau cov nyiaj plating txheej rau nyiaj hluav taws xob tiv tauj kom pom ntxhib lossis hlawv?
Ib txheej txheej ntxhib lossis hlawv plating feem ntau txuas nrog ntau qhov tam sim no ntom ntom, tsis yog - tsis sib xws hauv cov plating da dej muaj pes tsawg leeg, lossis kev ntxhov siab tsis txaus. In areas where current density is locally concentrated, abnormal grain growth can occur, resulting in an uneven surface finish or even a burnt appearance.
3. Yuav ua li cas qhov zoo ntawm nyiaj plating rau Hluav taws xob tiv tauj Silver Plated yuav zoo tswj kom txo tau qhov tsis xws luag?
Kev tswj kom zoo yuav tsum muaj kev qhia dav dav thoob plaws tag nrho cov txheej txheem- suav nrog kev ua ntej ua ntej- kev kho mob tu, ruaj khov ntawm qhov ceev tam sim no, kev pom ib ntus thiab tshuaj ntsuam xyuas ntawm lub plating da dej, thiab ua tiav tom qab- kev kho mob yaug thiab tiv thaiv. Tsis tas li ntawd, tsim kom muaj kev saib xyuas cov txheej txheem muaj zog thiab kev ua tau zoo traceability tuaj yeem txo qis tus nqi thiab txhim kho cov khoom sib xws.
