Hlau Plating
Kev siv tshuab hluav taws xob yog txheej txheem electrochemical thiab txheej txheem redox. Cov txheej txheem yooj yim ntawm electroplating yog txhawm rau ib feem hauv kev daws cov hlau ntsev raws li cathode, thiab cov hlau phaj ua ib qho anode, tom qab DC lub zog hluav taws xob, Plating tso rau qhov yuav tsum tau ntawm ntu.
Cov txheej txheem ntawm electroplating yog qhov pib raws li hauv qab no:
Lub plated hlau yog nyob ntawm qhov anode thiab cov khoom yuav tsum tau plated yog ntawm cathode.
Cov anode thiab cathode txuas nrog los ntawm cov tshuaj electrolyte muaj li ntawm plated hlau zoo ions.
Tom qab dhau ntawm DC lub zog muab hluav taws xob, cov hlau ntawm qhov anode yuav oxidize (poob cov hluav taws xob), thiab cov ions zoo hauv kev daws yuav txo (tau txais hluav taws xob) ntawm cathode los ua atoms thiab sib sau rau ntawm cathode.
Cov tsos ntawm cov phiaj plated tom qab electroplating cuam tshuam txog qhov ntau ntawm qhov tam sim no. Qhov me me dua tam sim no, qhov zoo nkauj dua lub nruas yuav plated; txwv tsis pub, qhov tsis xwm yeem yuav tshwm sim.
Kev siv hluav taws xob tseem ceeb suav nrog kev tiv thaiv hlau oxidation (xws li xeb) thiab kho kom zoo nkauj.
Lub luag hauj lwm ntawm electroplating:
1. Tooj liab plating: siv los ua cov txheej txheem los txhim kho lub nplaum ntawm txheej plating thiab muaj peev xwm tiv thaiv corrosion.
2. Npib tsib xee plating: lub hauv paus lossis lub ntsej muag, txhim kho kev txhim kho corrosion thiab hnav tsis kam, (qhov twg tshuaj lom neeg nickel tiv thaiv chrome ntau dua nyob rau hauv cov txheej txheem niaj hnub).
3. Kub plating: Txhim kho cov conductive tiv taus kuj thiab txhim kho cov teeb liab kis.
4. Palladium-plated npib tsib xee: Txhim kho cov conductive tiv taus tsis kam, txhim kho cov teeb liab kis, thiab hnav tsis kam siab dua kub.
5. Tin-plated lead: Txhim kho lub peev xwm vuam thiab yog hloov sai sai los ntawm lwm qhov hloov pauv.
6. Nyiaj plating: Txhim kho qhov conductive tiv taus kuj thiab txhim kho cov teeb liab kis.
Electroplating yog ib txoj kev los tso ib txheej hlau ntawm ib tus neeg xyuas pib siv txoj cai ntawm electrolysis. Ntxiv nrog rau cov xaim hluav taws xob, cov tshuab hluav taws xob kuj tseem siv tau rau cov tshuab kho tshwj xeeb.
Noj npib tsib xee plating ua piv txwv:
Thaum npib tsib xee plating, lub cathode yog qhov uas yuav tau plated, qhov anode yog ntshiab npib tsib xee phaj, thiab cov tshuaj tiv thaiv hauv qab no tshwm sim hauv qhov anode thiab cathode feem:
Cathode (plated): Ni2 ++ 2e- → Ni (lub ntsiab cuam tshuam)
2H ++ 2e → H2 ↑ (sab tshuaj tiv thaiv)
Anode (npib tsib xee phaj): Ni -2e → Ni2 + (cov tshuaj tiv thaiv tseem ceeb)
4OH - 4e- → 2H2O + O2 (kev tawm tsam sab)
Tshiab insoluble electrode - titanium anode:
Cov titanium anode muaj lub zog loj electrochemical catalytic zog, thiab cov pa oxygen overpotential yog li 0.5 V qis dua ntawm cov hlau lead alloy insoluble anode. Lub zog txuag tau zoo kawg li, qhov kev ruaj khov yog siab, plating plating tsis qias neeg, qhov hnyav yog lub teeb, thiab kev hloov pauv tau yooj yim.
Hom tau tsam:
1. Cov pa oxygen overpotential ntawm titanium anode tseem qis dua li ntawm lub platinized anode, tab sis lub neej ua haujlwm nce ntxiv ntau dua 1 lub sijhawm;
2. Nws tuaj yeem txo lub tank voltage thiab txuag hluav taws xob siv;
3. Titanium anode muaj zoo stability (tshuaj lom neeg, electrochemical) hauv cov txheej txheem electroplating thiab muaj lub neej ua haujlwm ntev.
Kev siv cov titanium electrodes hauv kev lag luam electroplating feem ntau xaiv cov txheej txheej nrog cov hlau tsis tshua muaj hlau, xws li tantalum coatings, tantalum coatings, thiab lwm yam.
Daim ntawv thov ntawm cov tsis tshua muaj hlau oxide txheej titanium anode hauv electroplating
Cov tsis tshua muaj hlau oxide txheej titanium anode yog ua los ntawm cov hlau tsis muaj nqi strontium ntsev coated rau ntawm titanium substrate thiab sintered ntawm qhov kub, thiab yog siv dav hauv hydrometallurgy kev lag luam xws li electroplating thiab electrolysis. Kev npaj thiab daim ntawv thov ntawm cov xim zoo hlau oxide coated titanium anodes yog qhov paub tab heev. Qhov zoo ntawm cov titanium anodes yog li nram no:
1.High tam sim no efficiency, zoo heev corrosion tsis kam, lub neej ntev anode thiab lub siab tam sim no.
2. lub zog txuag: cov hlau uas muaj nuj nqi oxide txheej titanium anode yog cov pa oxygen tsawg zuj zus overpotential electrode, nws yooj yim dua rau kev txheeb xyuas oxygen hauv oxygen oxygen cheeb tsam ntawm qhov anode. Yog li no, lub cell siab kuj tseem nyob qis thaum hluav taws xob, uas txuag hluav taws xob.
3. Tsis muaj kuab paug: noble hlau oxide txheej Titanium anode txheej yog ceramic oxide ntawm noble hlau niobium, uas yog cov oxide ruaj khov.
4.cost-efficiency: Yuav kom ua tiav qhov kev pab cuam tib lub neej ntawm platinized electrode, tus nqi ntawm cov hlau zoo hlau txheej txheej titanium anode yog li 80% ntawm cov platinized electrode.
5.Txoj kev saib xyuas tus nqi: piv rau cov tsoos soluble electrode, cov hlau oxide txheej txheej titanium anode tsis tas yuav hloov lub hnab anode tsis tu ncua thiab rov ua kom rov qab qhov anode, yog li cov khoom lag luam zoo dua, cov nqi zog txo;
6.Txhua kev ua haujlwm zoo tib yam, lub neej ntawm cov hlau noble oxide coated titanium anode nyob ntawm qhov ua hauj lwm tam sim no ntom ntom, kub thiab da dej ua ke.
