electroplating yog dab tsi?
Electroplating yog txheej txheem kev kho mob ntawm cov hlau uas siv electrolysis los coated txheej ntawm cov hlau los yog alloy ntawm cov hlau los yog lwm yam ntaub ntawv los txhim kho cov khoom zoo li, corrosion kuj, hnav tsis kam, conductivity thiab lwm yam khoom.
Thaum lub sij hawm electroplating txheej txheem, cov khoom yuav tsum tau plated yuav tsum tau siv raws li ib tug cathode nyob rau hauv kev sib cuag nrog cov tshuaj electrolyte, thaum cov hlau los yog alloy yog siv raws li ib tug anode thiab immersed nyob rau hauv cov tshuaj electrolyte. Los ntawm electrolysis, cov hlau los yog alloy ntawm lub anode poob electrons thiab dhau los ua lub xeev ionic, thiab raug txo rau cov hlau los yog alloy ntawm lub cathode los tsim cov txheej tshiab.
Electroplating tuaj yeem ua rau ntawm ntau yam ntaub ntawv, xws li hlau, yas, iav, ceramics, thiab lwm yam, thiab muaj ntau yam kev siv, xws li tsheb, aerospace, electronics, machinery, tshuaj lom neeg kev lag luam thiab lwm yam.
txoj kev electroplating
1. Tank plating: Los ntawm kev siv cov khoom raws li cathodes hauv cov electrolyte, hlau yog electrolyte-deposited rau lawv qhov chaw.
2. Barrel plating: Txhawm rau tso cov hlau rau ntawm qhov chaw, muab cov khoom tso rau hauv lub nruas thiab yob rau hauv cov electrolyte.
3. Rack plating: los ntawm kev ncua cov khoom hauv cov electrolyte thiab siv electrolysis los tso cov hlau rau ntawm lawv qhov chaw.
4. Txhuam plating: Siv cov txhuam hniav electrolyte, txheej txheej txheej txheej nrog hlau los ntawm electrolysis.
5. Nqus plating: Hlau vapor yog siv rau ntawm qhov chaw thaum nws nyob hauv lub tshuab nqus tsev.
6. Electroless plating: Ib qho tshuaj tiv thaiv ua rau tsim cov hlau txheej ntawm qhov chaw.
qhov zoo thiab qhov tsis zoo
qhov zoo:
◎ Txhim kho corrosion kuj: Electroplating tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau nto los txhim kho corrosion kuj ntawm cov hlau.
◎Txhim kho cov khoom zoo nkauj: Electroplating tuaj yeem ua rau cov hlau saum npoo ci dua thiab zoo nkauj dua, thiab txhim kho cov khoom zoo nkauj ntawm cov khoom.
◎Txhim kho conductivity: Electroplating tuaj yeem tsim ib zaj duab xis conductive ntawm cov hlau saum npoo los txhim kho cov conductivity ntawm cov hlau.
◎Txhim kho kev hnav tsis kam: Electroplating tuaj yeem tsim cov yeeb yaj kiab hnav-tiv taus ntawm cov hlau saum npoo los txhim kho qhov hnav tsis kam ntawm cov hlau.
◎ Txhim kho weldability: Electroplating tuaj yeem tsim cov yeeb yaj kiab weldable ntawm cov hlau nto los txhim kho qhov weldability ntawm cov hlau.
qhov tsis zoo:
◎Ib puag ncig muaj kuab paug: Cov dej khib nyiab ntau, cov roj khib nyiab thiab cov khib nyiab pov tseg yuav raug tsim thaum lub sij hawm electroplating txheej txheem, ua rau muaj kuab paug rau ib puag ncig.
◎ Tus nqi siab: Electroplating yuav tsum muaj ntau yam khoom siv thiab lub zog, thiab tus nqi siab.
◎Cov txheej txheem nyuaj: Electroplating yuav tsum muaj ntau yam txheej txheem, cov txheej txheem nyuaj, thiab nws yuav tsum tau ua haujlwm siab rau cov neeg ua haujlwm.
◎Limited txheej thickness: txheej thickness ntawm electroplating yog txwv thiab tsis tuaj yeem ua tau raws li qee qhov kev xav tau tshwj xeeb.
◎Cov teeb meem tsis zoo yuav tshwm sim: Cov teeb meem tsis zoo yuav tshwm sim thaum lub sij hawm electroplating, xws li plating tsis sib xws, tev, tev, thiab lwm yam.
Feem ntau, electroplating yog ib qho kev siv tshuab kho qhov chaw. Nws tuaj yeem txhim kho corrosion kuj, kho kom zoo nkauj, conductivity, hnav tsis kam thiab weldability ntawm cov hlau, tab sis nws kuj muaj qee qhov tsis zoo, xws li kev ua qias tuaj ib puag ncig, tus nqi siab, cov txheej txheem nyuaj, txwv txheej tuab thiab muaj qhov tsis xws luag, thiab lwm yam. Yog li ntawd, thaum xaiv txheej txheem electroplating, nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog nws qhov zoo thiab qhov tsis zoo thiab xaiv cov txheej txheem tsim nyog tshaj plaws.
