NdFeB hlau nplaum yog tetragonal crystals tsim los ntawm neodymium, hlau, thiab boron (Nd2Fe14B). NdFeB hlau nplaum yog dav siv nyob rau hauv electronics, hluav taws xob machinery, khoom kho mob, cov khoom ua si, ntim, hardware machinery, aerospace thiab lwm yam teb. Feem ntau muaj xws li cov hlau nplaum ruaj khov motors, hais lus, sib nqus sib nqus, lub computer disk drives, cov khoom siv magnetic resonance imaging thiab cov twj paj nruag, thiab lwm yam.
Txhawm rau kom tsis txhob muaj kev puas tsuaj, qhov chaw ntawm cov hlau nplaum ruaj khov yuav tsum tau tiv thaiv thaum siv, xws li electroplating nrog kub, npib tsib xee, zinc, tin, thiab txau epoxy resin rau saum npoo.
NdFeB muab faib ua ob hom: sintered NdFeB thiab bonded NdFeB:
Bonded NdFeB hlau nplaum yog sib nqus nyob rau hauv tag nrho cov lus qhia thiab resistant rau corrosion;
Txij li thaum sintered NdFeB hlau nplaum yog nquag corrosion, qhov saum npoo yuav tsum tau plated. Feem ntau, muaj zinc plating, nickel plating, ib puag ncig tus phooj ywg zinc, ib puag ncig tus phooj ywg npib tsib xee, npib tsib xee tooj liab npib tsib xee, ib puag ncig tus phooj ywg npib tsib xee tooj liab npib tsib xee, thiab lwm yam. nto.
Tom qab ib lub sijhawm ntawm kev siv cov hlau nplaum NdFeB muaj zog, qhov zoo li qub yuav maj mam tsim cov xim dawb lossis lwm yam xim, uas maj mam nthuav dav thiab ua rau xeb. Feem ntau hais lus, txheej ntawm NdFeB hlau nplaum tsis yooj yim kom xeb. , Kev puas tsuaj los ntawm xeb thiab xeb ntawm NdFeB hlau nplaum feem ntau yog vim muaj cov hauv qab no:
1. Cov av ntawm cov hlau nplaum NdFeB tsis huv ua ntej electrolysis;
2. Lub hnab yas ntim sab nraud ntawm NdFeB hlau nplaum tsis zoo kaw, ua rau huab cua oxidation ntawm cov hlau nplaum;
3. Lub sijhawm ntawm cov txheej txheem electroplating tsis yog raws li tus qauv lossis muaj teeb meem kev ua haujlwm;
4. Qhov chaw uas NdFeB cov hlau nplaum khaws cia muaj cov av noo siab, qhov cua hauv tsev tsis zoo, thiab qhov kub thiab txias hloov pauv.
