Raws li ib txwm muaj, cov hlau nplaum saum npoo av muaj txheej txheej ntawm electroplating (ntawm chav kawm, kuj tseem muaj cov kev cai rau NdFeB yam tsis muaj electroplating. Cov hlau nplaum ntawm qee cov khoom siv tsis xav tau electroplating, thiab cov tsos zoo ib yam li ferrite). Lub sijhawm no, tsis muaj cov kab xeb. ntawm. Feem ntau, cov kab xeb tshwm sim vim tias nws tau nyob hauv ib puag ncig nrog cov av qis, thiab huab cua ncig hauv qhov chaw ua haujlwm tsis zoo. Cov hlau nplaum yuav tsum tau muab tso rau hauv qhov chaw uas muaj qhov cua zoo thiab qee qhov kub sib txawv.
Tsis tas li ntawd, tsis muaj sijhawm txaus rau electroplating, thiab electroplating tsis zoo los ntawm cov chaw tsim khoom hlau nplaum kuj yog ib qho laj thawj. Qhov no yog ib qho teeb meem ntawm cov txheej txheem ntws.
Tsis tas li ntawd, yog tias lub ntim ntim ntawm cov hlau nplaum muaj zog puas lawm, nws tseem yuav ua rau oxidation ntawm cov hlau nplaum muaj zog, ua rau xeb.
Lwm lub ntsiab lus tseem ceeb yog tias cov av ntawm qhov chaw ntawm cov hlau nplaum tsis raug ntxuav kom zoo ua ntej electroplating, uas kuj yog ib qho laj thawj rau cov tsos ntawm xeb.
Cov hlau nplaum NdFeB hauv av yuav xeb. Txoj hauv kev los tiv thaiv xeb yog kom tsis txhob nthuav tawm qhov chaw rau dej thiab huab cua. Tsuas yog muab tso rau hauv dej (nws yog qhov zoo dua yog alkaline thiab cov pa roj carbon dioxide raug tshem tawm) los yog qhuav tam sim ntawd thiab kaw nws (nws yog qhov zoo dua los khaws nws nrog roj). Tom qab sib tsoo, nws raug nquahu kom qhuav nws nrog lub tshuab ziab khaub ncaws ultrasonic tam sim kom txo cov xeb. .
NdFeB cov hlau nplaum muaj zog yuav tsum zam cov txheej txheem khaws cia hauv qab no:
1. Nyob rau hauv ib qho chaw uas ntub dhau thiab muaj cua tsis zoo.
2. Thaum qhov sib txawv ntawm qhov kub thiab txias, txawm tias cov khoom uas tau dhau los ntawm kev ntsuas tshuaj ntsev tuaj yeem tsim cov kab xeb yog tias lawv khaws cia rau hauv qhov chaw hnyav rau lub sijhawm ntev. Yog tias tsis muaj txheej txheej ntawm qhov chaw, koj tuaj yeem xaiv siv lub desiccant lossis vapor theem xeb inhibitor thiab khaws cia rau hauv ib lub hnab ntim khoom.
3. Cov khoom siv hlau nplaum electroplated yuav tsum tsis txhob muab tso rau hauv qhov chaw muaj av noo ntev, tab sis yuav tsum muab tso rau hauv qhov chaw txias, qhuav.
