1. Gravure Printing ua haujlwm li cas thiab vim li cas lub tog raj kheej xav tau electroplating?
Gravure printing yog ua raws li lub tog raj kheej engraved.
Tsis zoo li cov txheej txheem luam ntawv uas cov duab tau nqa mus rau saum npoo av, gravure luam ntawv siv ntau txhiab lub microscopic recessed hlwb engraved rau saum npoo ntawm lub tog raj kheej.
Thaum lub sij hawm luam ntawv, cov hlwb no tuav tus number case. Ntau tus number case raug tshem tawm ntawm qhov tsis yog - daim duab saum npoo, thaum tus number case tseem nyob hauv cov engraved hlwb raug xa mus rau cov khoom luam ntawv.
Qhov no txhais tau tias qhov zoo ntawm lub tog raj kheej yog qhov tseem ceeb heev.
Ua ntej engraving, lub tog raj kheej xav tau ib tug nto uas yuav tsum tau machined thiab engraved. Tom qab engraving, qhov saum npoo yuav tsum tuaj yeem rov ua dua txhua yam kev sib cuag thaum luam ntawv.
Qhov no yog vim li cas electroplating plays ob lub luag haujlwm tseem ceeb hauv gravure lub tog raj kheej tsim.
Ib txheej tooj liab feem ntau yog siv ua ntej engraving.
Copper muab cov xim hlau tsim nyog rau kev tsim cov hlwb zoo uas xav tau rau cov duab luam ntawv.
Qhov zoo thiab sib xws ntawm cov txheej tooj liab no yog li cuam tshuam rau cov txheej txheem engraving thiab ua tiav tom ntej.
Tom qab engraving, lub tog raj kheej nto yuav tsum muaj kev tiv thaiv ntxiv.
Ib txheej tawv chromium feem ntau yog siv rau saum npoo ntawm tooj liab txhawm rau txhim kho hnav tsis kam thaum luam ntawv.
Yog li ntawd, lub simplified manufacturing ib theem zuj zus tuaj yeem qhia tau tias:
Kev npaj lub tog raj kheej → Copper Plating → Nto → Engraving → Chromium Plating → Finishing → Printing

Ib qho anode haum rau ib txheej txheej plating yuav tsum tsis txhob cia li xav tias tsim nyog rau lwm tus.
2. Electroplating ua haujlwm li cas hauv Gravure Cylinder Manufacturing?
Electroplating yog txheej txheem electrochemical nyob rau hauv uas hluav taws xob tam sim no tsav cov tshuaj tiv thaiv uas tso ib txheej hlau mus rau qhov chaw conductive.
Nyob rau hauv lub gravure lub tog raj kheej plating tank, lub hauv paus system muaj xws li:
DC Power Supply + Anode + Electrolyte + Gravure Lub tog raj kheej Cathode
Lub tog raj kheej gravure txuas nrog raws li tuscathode, thaum lub anode txuas nrog rau sab zoo ntawm DC fais fab mov.
Thaum tam sim no dhau los ntawm qhov system, electrochemical cov tshuaj tiv thaiv tshwm sim ntawm ob qho tib si electrode.
Ntawm lub cathode, hlau-muaj hom nyob rau hauv cov electrolyte raug txo thiab hlau tso rau ntawm lub tog raj kheej nto.
Qhov tseeb anodic cov tshuaj tiv thaiv nyob ntawm plating chemistry thiab hom anode siv.
Qhov no yog ib qho laj thawj xaiv anode tsis tuaj yeem sib cais los ntawm da dej chemistry.
Lub Anode cuam tshuam ntau tshaj qhov hluav taws xob Circuit Court
Los ntawm cov tswv yim engineering, ntau yam anode- cuam tshuam tuaj yeem cuam tshuam cov txheej txheem plating:
● cov khoom siv anode;

Yog tias lub kaw lus uas twb muaj lawm twb muaj qhov sib txawv, qhov no yuav tsum tau muab tso rau hauv cov ntaub ntawv qhia.
7. Cov ntaub ntawv Anode uas twb muaj lawm
Rau ib txoj kab plating uas twb muaj lawm, cov ntaub ntawv hais txog cov electrode tam sim no yog qhov tseem ceeb heev.
Qhov no yuav suav nrog:
● cov khoom siv anode;
● qhov ntev;
● kos duab;
● duab;
● raug kev khiav hauj lwm voltage;
● kev pab lub neej;
● hom tsis ua hauj lwm;
● siv electrode qauv qhov twg muaj.
Ib qho anode siv tau qee zaum muab cov ntaub ntawv tseem ceeb txog kev ua haujlwm tiag tiag thiab cov qauv tsis ua haujlwm.
8. Kev sib txuas hluav taws xob
Cov electrode kuj tseem yuav tsum sib xyaw kom raug nrog cov khoom siv hluav taws xob uas twb muaj lawm thiab busbar system.
Kev sib txuas txoj hauj lwm, tam sim no - nqa cov kev xav tau, kev teeb tsa, thiab kev sib cuag tsim yuav tsum tau txiav txim siab thaum tsim khoom.
9. Lub sijhawm ua haujlwm
Puas yog cov kab plating ua haujlwm:
tsis tu ncua;
tsis tu ncua;
nyob rau hauv ntau zaus;
nrog nquag pib- nres cycles?
Kuj tseem qhia meej seb lub anode tseem nyob rau hauv thaum lub hwj chim raug kaw.
Cov ntsiab lus kev khiav hauj lwm no tuaj yeem cuam tshuam thaum ntsuas cov kev pabcuam electrode.
10. Cov txheej txheem uas twb muaj lawm
Yog tias lub hom phiaj ntawm kev hloov cov electrode yog los daws qhov teeb meem uas twb muaj lawm, piav qhia qhov teeb meem ncaj qha.
Piv txwv tej zaum yuav muaj xws li:
● luv electrode lub neej;
● plating tsis sib xws;
● hloov anode geometry;
● tsis ruaj tsis khov kev khiav hauj lwm voltage;
● nyuaj electrode-gap tswj;
● kev saib xyuas tsis tu ncua;
● kev txhawj xeeb txog kev kis kab mob;
● xav tau ib tug customized zoo.
Qhov no pab kom cov electrode tshiab yog tsim nyob ib ncig ntawm lub hom phiaj tiag tiag es tsis yog tsuas yog rov tsim dua qhov qub qhov ntev.
11. Cia siab rau kev pab cuam lub neej
Yog tias qhov project muaj qhov kev pabcuam - lub hom phiaj lub neej, nws yuav tsum tau tham ua ke nrog qhov ceev thiab txheej txheej tam sim no.
Kev pabcuam lub neej tsis tuaj yeem ntsuas qhov muaj txiaj ntsig los ntawm qhov ntev ib leeg.
Kev xav zaum kawg: Xaiv lub Anode rau cov txheej txheem, tsis yog kos duab xwb
Rau gravure lub tog raj kheej electroplating, lub anode yuav tsum tsis txhob raug kho raws li ib tug fabricated titanium tivthaiv.
Nws qhov kev ua tau zoo nyob ntawm kev sib cuam tshuam ntawm:
Electrolyte + Anodic Reaction + Active Coating + Active Area + Tam sim no ntom + Geometry + Electrode Gap + Kev Ua Haujlwm
Rau tooj liab plating, nws tseem yog ib qho tseem ceeb kom paub qhov txawv ntawm soluble-anode thiab insoluble-anode txheej txheem tswvyim.
Rau coated titanium anodes,Ir-Ta MMO thiab Pt/Ti muab qhov chaw sib txawv thiab yuav tsum tau xaiv raws li qhov tseeb electrochemical ib puag ncig.
Nyob rau tib lub sijhawm, gravure lub tog raj kheej geometry ua rau kev tsim kho tshuab tshwj xeeb.
Lub qhov dej-tsim electrode thiaj li ua ke:
Correct Titanium Structure + Correct Active Area + Correct Coating System + Correct Current Density
Lub hom phiaj tsis yog tsuas yog tsim cov titanium anode uas haum rau hauv lub plating tank.
Nws yog los tsim ib qho electrode uas haum rau cov txheej txheem electrochemical.
Xav tau Titanium Anode rau koj lub tog raj kheej Gravure Plating Line?
Ehisen tsim khoIr-Ta MMO titanium anodes thiab platinized titanium (Pt/Ti) anodesrau kev lag luam electrochemical thiab electroplating daim ntaub ntawv.
Rau qhov kev ntsuam xyuas thawj zaug, koj tuaj yeem muab:
Plating Application + Electrolyte + Kev khiav hauj lwm tam sim no + Kub + Lub tog raj kheej Dimensions + Electrode Gap + Cov ntaub ntawv uas twb muaj lawm Anode + Teeb duab lossis duab
Raws li cov kev ua haujlwm no, cov qauv electrode, thaj chaw ua haujlwm zoo, txheej txheej txheej txheej, thiab txheej txheej txheej tuaj yeem ntsuas ua ke.
