Daim ntawv thov ntawm cov hlau nplaum muaj zog NdFeB cuam tshuam rau txhua qhov chaw ntawm lub neej. Cov ntawv thov sib txawv thiab cov khoom lag luam muaj cov kev xav tau sib txawv rau cov hlau nplaum, xws li kub tsis kam, tshuaj tsuag tshuaj tsw qab, kev ua siab ntev, thiab lwm yam. Qee cov neeg yuav khoom yuav tsis qhia rau cov chaw tsim khoom hlau nplaum txog qhov xav tau ntawm qhov kub thiab txias vim tsis muaj kev nkag siab ntawm cov hlau nplaum, los yog lawv. tej zaum yuav ncaj qha pom cov specifications haum rau lawv nyob rau hauv Internet, thiab tus nqi yog txais, ces lawv pib mus yuav. Txawm li cas los xij, nws yooj yim rau demagnetization thaum siv, lossis cov hlau nplaum tsis tas yuav tsum tau hlau nplaum, tab sis cov chaw tsim khoom hlau nplaum tsis tau piav qhia meej, ua rau muaj kev sib nqus. Feem ntau, cov hlau nplaum yog magnetized los ntawm lub neej ntawd thaum xa khoom.
Yog li tuaj yeem muaj zog sib nqus neodymium hlau nplaum tuaj yeem rov ua dua tom qab kub demagnetization?
Cov lus teb yog tias lawv tuaj yeem ua tau hlau nplaum, tab sis lawv tsis tuaj yeem ncav cuag qhov qub, uas yog, cov khoom sib nqus hauv lub cev tau qis dua thiab tsis tuaj yeem rov qab los, yog li nws yog qhov tsim nyog rau koj kom nkag siab qhov kub thiab txias ntawm ntau yam hlau nplaum.
Disadvantages ntawm kub demagnetization thiab re-magnetization ntawm NdFeB:
Magnetic poob: Tom qab kev kho qhov kub thiab txias, lub microstructure hauv cov hlau nplaum yuav hloov, ua rau ib nrab lossis ua tiav cov hlau nplaum. Txawm hais tias nws yog re-magnetized, nws cov hlau nplaum yuav tsis rov qab los rau nws qib dhau los.
Cov qauv kev hloov pauv: qhov kub thiab txias yuav ua rau muaj kev hloov pauv ntawm cov qauv lattice hauv cov hlau nplaum, ua rau nws yooj yim dua los yog raug cuam tshuam los ntawm kev cuam tshuam sab nraud.
Tus nqi thiab kev ua haujlwm: Cov txheej txheem remagnetization yuav xav tau sijhawm ntxiv thiab cov peev txheej, thiab yuav tsis tuaj yeem rov qab ua cov hlau nplaum qub.
