Yuav ua li cas rau demagnetize lub nplhaib?
NdFeB nplhaib tau tsim muaj kev ua lag luam ntawm lub ntiaj teb tsis muaj praceodymium neodymium thiab hlau alloy, cov khoom siv tam sim no yog siv hauv khw, tab sis haib hlau nplaum feem ntau ntsib nyob rau hauv lub chav kawm ntawm sib nqus quab yuam txo los yog disappears, sau cov hauv qab no:
1: Demagnetization lossis demagnetization tom qab txhaj tshuaj hlau magnet, qhov kub ntxhov feem ntau yog 80 ℃ , cov hlau nplaum raug ntau tshaj 12 ℃ .
2: Tom qab cov hlau nplaum tshav kub los yog degaussing, feem ntau nws siv cov iav fiber ntau kub, kub dua 150 ℃ .
3: Hlau nplaum tom qab qhov cub ci ntsa iab
4: Cov khoom siv hlau nplaum muaj ntau impurities ua rau tsis muaj zog hlau nplaum,
5: Tej yam yuav tshwm sim hauv kev siv cov hlau nplaum, xws li kev cuam tshuam ntau zaus.
6: Cov ntaub ntawv muaj hlau lanthanum, uas ua rau cov hmoov hlau nplaum thiab lwm yam.
7: Kev sib nqus siab nrug thaj tsam yog qhov sib nqus quab yuam ntawm cov hlau nplaum uas ploj los yog N / S ncej hloov ( magnetizing tshuab los yog demagnetizer )
Qhov saum toj no demagnetization (degaussing) ua rau 90% ntawm cov ntsiab lus hais txog cov ntsiab lus, kev kub siab, kev siv cov khoom siv, kev cuam tshuam kev ua pa loj, kev sib nqus loj magnetic demagnetization.
