Magnet manufacturers qhia koj yuav ua li cas kom lub zog sib nqus ntawm cov hlau nplaum. Piv nrog cov hlau nplaum ferrite, AlNiCo thiab Samarium Cobalt, cov khoom sib nqus ntawm cov hlau nplaum zoo heev tshaj cov ntawm lwm cov hlau nplaum. NdFeB hlau nplaum tuaj yeem nqus tau 640 npaug ntawm lawv tus kheej qhov hnyav. Yog li ntawd, NdFeB feem ntau hu ua cov hlau nplaum muaj zog los ntawm cov neeg sab nrauv. Dab tsi yog txoj kev degaussing rau cov hlau nplaum muaj zog? Niaj hnub no, cov chaw tsim khoom siv hlau nplaum yuav qhia koj cov hauv qab no.
1. Vibration demagnetization txoj kev
Cov tuam txhab hlau nplaum qhia koj ua haujlwm yooj yim heev, uas yog ua kom muaj zog thiab khaus vibrations ntawm cov hlau nplaum muaj zog. Tom qab kev vibration ua haujlwm, cov qauv sab hauv ntawm cov hlau nplaum hloov, yog li hloov lub cev lub zog ntawm cov hlau nplaum. Feem ntau hais lus, txoj kev no yog siv. Txoj kev demagnetization tsis tshua muaj txiaj ntsig, thiab tsuas yog qee qhov me me ntawm demagnetization tuaj yeem siv tau ib ntus.
2. Kev kub siab demagnetization txoj kev
Lub luag haujlwm tseem ceeb ntawm txoj kev kub-kub demagnetization yog muab cov hlau nplaum tso rau hauv qhov cub kub kub rau cua sov. Tom qab kev kho kub kub, cov hlau nplaum ntawm cov hlau nplaum muaj zog yuav raug tshem tawm, tab sis thaum lub sij hawm cua sov, cov nyhuv ntawm qhov kub thiab txias yuav ncaj qha mus rau cov qauv ntawm cov khoom hauv cov hlau nplaum. Cov kev hloov pauv loj tau tshwm sim, yog li no txoj kev demagnetization feem ntau yog siv rau cov khoom siv hlau nplaum thiab rov siv dua.
Magnet manufacturers qhia koj yuav ua li cas kom hlau nplaum magnetism
Nrog rau kev siv cov hlau nplaum hauv ntau thiab ntau kev lag luam, koj puas tau kawm txog cov hlau nplaum ntawm cov hlau nplaum? Yuav ua li cas yog cov hlau nplaum hlau nplaum tsis muaj zog lossis ploj? Koj puas paub? Nws tsis muaj teeb meem, hnub no cov chaw tsim khoom hlau nplaum yuav qhia rau koj paub meej tias yuav ua li cas kom cov hlau nplaum ntawm cov hlau nplaum.
1. Txoj kev yooj yim tshaj plaws yog rov ua cov hlau nplaum rov ua kom nws ncav cuag lub xeev ntawm magnetization saturation.
2. Cov txheej txheem ntawm kev tsim hluav taws xob sib nqus sib sau ua ke sib nqus flux ntawm tus quab los ua kom muaj zog nqus zog.
3. Cov txheej txheem ntawm kev sib nqus cov kab sib nqus ntawm lub zog tuaj yeem siv los nyiam cov hlau nplaum conductive ntawm cov hlau nplaum, thiab cov chaw tsim khoom hlau nplaum yuav tsim cov hlau nplaum ntau dua ntawm cov npoo, cov fab thiab cov npoo ntawm cov hlau nplaum hlau nplaum.
4. Cov chaw tsim khoom hlau nplaum qhia rau koj tias tsis tas yuav txhawj xeeb yog tias lub zog sib nqus tsis txaus. Koj tuaj yeem ntxiv ib daim ntawv hlau rau lwm phab ntsa ntawm cov hlau nplaum kom ntxiv dag zog rau cov hlau nplaum. Cov chaw tsim khoom siv hlau nplaum siv cov hlau nplaum saum npoo ntawm lub sijhawm no.
