Puas yog Neodymium Magnets Rust?

Ua rau xeb Spots hauv NdFeB Magnets:

 

Raws li ib txwm muaj, qhov saum npoo ntawm cov hlau nplaum muaj txheej txheej ntawm electroplating (ntawm chav kawm, kuj tseem muaj cov hlau nplaum NdFeB uas yuav tsum tsis muaj electroplating, qee cov hlau nplaum rau cov tshuab ua ntxhia tsis xav tau electroplating, thiab cov tsos zoo ib yam li ferrite), thiab muaj. tsis muaj xeb nyob rau lub sijhawm no Lub hav zoov ntawm xeb feem ntau 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. Dab tsi yuav tsum tau ceeb toom cov phooj ywg yog tias cov hlau nplaum yuav tsum tau muab tso rau hauv cov chaw uas muaj qhov cua zoo thiab qee qhov qhov kub ntawm qhov sib txawv.

 

Tsis tas li ntawd, lub sij hawm rau electroplating tsis txaus, thiab cov neeg pluag electroplating ntawm hlau nplaum manufacturers kuj yog ib qho ntawm cov laj thawj, uas belongs rau qhov 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 oxidize cov hlau nplaum uas muaj zog, uas ua rau muaj 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.

 

Hauv av NdFeB hlau nplaum yuav xeb. Txoj hauv kev los tiv thaiv xeb yog kom tsis txhob ntog los ntawm dej thiab huab cua. Tsuas yog muab tso rau hauv dej (zoo dua nrog alkaline, thiab cov pa roj carbon dioxide yuav raug tshem tawm) los yog qhuav thiab kaw nws tam sim ntawd (zoo dua nrog roj) Tom qab sib tsoo, nws raug nquahu kom qhuav nws hauv 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 qhov chaw uas muaj av noo ntau heev thiab tsis zoo cua ncig.

2.Thaum qhov sib txawv ntawm qhov kub thiab txias, txawm tias cov khoom uas dhau los ntawm cov tshuaj tsuag tshuaj ntsev tuaj yeem tsim cov kab xeb yog tias lawv khaws cia rau hauv 3. ib puag ncig hnyav rau lub sijhawm ntev.

4.Yog tias tsis muaj txheej txheej ntawm qhov chaw, koj tuaj yeem xaiv siv lub desiccant los yog vapor theem xeb inhibitor, thiab muab tso rau hauv ib lub hnab ntim khoom.

Cov khoom siv hlau nplaum electroplated yuav tsum tsis txhob muab tso rau hauv qhov chaw uas muaj cov av noo siab ntev, tab sis yuav tsum muab tso rau hauv qhov chaw txias thiab qhuav.
