Muaj pes tsawg leeg thiab kev ua tau zoo ntawm Passivation Zaj duab xis ntawm Galvanized Sheet ntawm Hluav Taws Kub Kub Tube
Tom qab galvanizing, qhov saum npoo ntawm cov hlau phaj yuav tsum tau txais kev kho mob passivation, tab sis qee zaum kev ua haujlwm ntawm tus neeg sawv cev passivation tsis ruaj khov thiab cov nyhuv passivation tsis zoo, uas ua rau kev tsim khoom tsis ua haujlwm zoo. Cov khoom sib xyaw thiab cov qauv ntawm cov yeeb yaj kiab passivation txiav txim siab nws qhov kev ua tau zoo, yog li ntawd, qhov sib xyaw thiab kev tiv thaiv corrosion ntawm cov yeeb yaj kiab passivation ntawm cov ntawv galvanized tau tham. Lub morphology ntawm cov tshuaj passivation tus neeg sawv cev tau soj ntsuam siv SEM thiab TEM txoj kev, thiab cov morphology ntawm daim ntawv galvanized tom qab passivation tau soj ntsuam siv SEM. Tom qab passivation, qhov saum npoo ntawm daim ntawv zinc ua tiaj tus thiab qhov tsis xws luag raug txo; Thiab EDS tau siv los txheeb xyuas cov tshuaj muaj pes tsawg leeg ntawm cov yeeb yaj kiab passivation, uas muaj Zn, O, Cr, C; Txoj kev tsom xam AES nto tau siv los txheeb xyuas qhov kev hloov pauv ntawm ntau lub ntsiab lus nrog lub thickness ntawm zaj duab xis. Cov ntsiab lus ntawm cov ntsiab lus tshwj tsis yog Zn txo qis rau xoom raws li cov yeeb yaj kiab thickness nce; Txais XPS thev naus laus zis.
Thaum ua cov txheej txheem electroplating, cov kev xav tau rau cov khoom siv hluav taws xob yog qhov siab. Cov khoom siv hluav taws xob zoo tuaj yeem txhim kho kev ua haujlwm. Yog li dab tsi yog qhov yuav tsum tau muaj rau cov khoom siv hluav taws xob hauv electroplating ua rau cov lag luam?
1. Kev ntseeg siab ntawm cov khoom siv hluav taws xob thaum lub sij hawm ua electroplating yog ib qho tseem ceeb heev, feem ntau yog xa mus rau lub rationality ntawm cov qauv, kev ruaj ntseg, cov yam ntxwv ntawm Circuit Court, txias txoj kev, thiab lwm yam.
2. Thaum xaiv cov khoom siv hluav taws xob, nws yog ib qho tseem ceeb uas yuav tsum muaj tus nqi sib piv. Cov khoom siv hluav taws xob sib txawv muaj cov nqi sib txawv, thiab cov tuam txhab yuav tsum xaiv raws li lawv tus kheej qhov xwm txheej.
3. Ua raws li cov lus qhia tshwj xeeb uas yuav tsum tau ua los ntawm cov txheej txheem electroplating, suav nrog lub zog loj ntawm cov khoom siv hluav taws xob, cov ntsuas waveform, adjustable ntau yam ntawm cov nqi tam sim no thiab voltage, thiab lwm yam.
4. Raws li cov kev xav tau ntawm cov txheej txheem electroplating thiab cov xwm txheej ntawm qhov chaw electroplating, lub waveform, txias txoj kev, ntim loj, thiab corrosion kuj ntawm electroplating fais fab mov yuav tsum tau xaiv, nrog rau cov nqi sib npaug.
Yog li thaum xaiv cov txheej txheem electroplating, nws yog ib qho tsim nyog yuav tau xaiv lub hwj chim tsim nyog los xyuas kom meej qhov ua tau zoo thiab kev ua haujlwm ntawm electroplating.
