Lub ntsiab ntsev nyob rau hauv cov hluav taws xob cua sov raj tov yog qhov tseem ceeb tshaj plaws uas txiav txim siab cov electroplating kev ua tau zoo thiab zoo

Lub ntsiab ntsev hauv cov tshuaj yog qhov tseem ceeb tshaj plaws uas txiav txim siab qhov ua tau zoo thiab qhov zoo ntawm electroplating. Thaum cov ntsiab lus ntawm cov ntsev tseem ceeb yog qis dua li cov txheej txheem yuav tsum tau ua, qhov kev ua haujlwm tam sim no txo ​​qis, qhov ceev tam sim no txo ​​qis, qhov chaw taw qhia tau yooj yim hlawv, cov nyhuv ntawm lub teeb ci txo qis, thiab txawm tias cov txheej txheem tsis tuaj yeem tau txais hauv thaj chaw qis tam sim no. . Thaum cov ntsiab lus ntawm cov ntsev tseem ceeb siab dua li cov txheej txheem yuav tsum tau ua, qhov kev ua haujlwm tam sim no kuj yuav txo qis, thiab qhov poob tawm los ntawm cov tshuaj plating yuav nce ntxiv.

Tus nqi pH yog qhov tseem ceeb hauv cov txheej txheem electroplating. Tus nqi pH ntawm cov tshuaj plating yuav tsum tau kuaj tsis tu ncua thiab sau tseg raws li. Yog tias nws dhau qhov txheej txheem ntau, nws yuav tsum tau hloov kho raws sijhawm. Txoj kev hloov kho yog kom dilute cov kua qaub los yog alkali nrog tib ion raws li cov ntsev tseem ceeb thiab ntxiv nws thaum nplawm. Nws tsis raug tso cai ncaj qha ntxiv cov kua qaub lossis alkali ncaj qha rau cov tshuaj plating.

Qhov kub thiab txias kuj yog ib qho tseem ceeb cuam tshuam rau cov khoom zoo. Piv txwv li, soaking aluminium thiab aluminium alloys hauv dej sov tom qab conductive oxidation yog qhov tsim nyog tiv thaiv txheej txheem. Qhov kub ntawm cov dej sov yuav tsum tsis txhob siab tshaj 50 degree, uas yog txaus kom tshem tawm tag nrho cov oxidation tov nyob rau saum npoo ntawm oxide zaj duab xis thiab ntxuav lub nto ntawm oxide zaj duab xis, yog li txhim kho kev tiv thaiv kev ua tau zoo ntawm oxide zaj duab xis txheej. Qhov kub thiab txias dhau los ua rau muaj kev puas tsuaj rau qhov zoo ntawm cov yeeb yaj kiab txheej, vim nws tuaj yeem ua rau cov kab nrib pleb thiab qhov hws, txo cov conductivity thiab tiv thaiv kev ua haujlwm ntawm cov yeeb yaj kiab txheej. Lub ziab kub ntawm txhuas thiab nws cov alloys tom qab conductive oxidation yuav tsum tsis txhob ntau tshaj 50 degree.

Lub sijhawm ua haujlwm yuav tsum tau tswj nruj heev. Piv txwv li, zaj duab xis txheej tau los ntawm kev ua oxidation ntawm txhuas thiab nws cov alloys nruj me ntsis raws li cov txheej txheem yuav tsum muaj zoo conductivity. Yog hais tias lub sij hawm oxidation ntev dhau lawm thiab lub thickness ntawm cov zaj duab xis txheej nce, tsis tsuas yog nws yuav cuam tshuam rau conductivity ntawm cov zaj duab xis txheej, tab sis cov zaj duab xis txheej kuj yuav tshwm nyob rau hauv lub ntiaj teb daj thiab outdated.

Additives muaj kev cuam tshuam zoo rau qhov zoo ntawm electroplating. Txhawm rau tiv thaiv tsis txaus lossis ntau ntxiv, nws yog qhov zoo tshaj kom ntxiv lawv ntau zaus raws li kev noj. Tsis tas li ntawd, txhua yam tshuaj lom neeg ntxiv rau hauv lub plating tank yuav tsum tau sau rau ntawm lub luag haujlwm, txhawm rau txheeb xyuas qhov ua rau thiab ntsuas raws sijhawm thaum muaj qhov txawv txav.
