Cov hlau nplaum muaj zog tsis yog tsuas yog muaj cov kev xav tau ntawm qhov chaw ua haujlwm tab sis kuj nyob rau hauv ib puag ncig sab hauv. Piv nrog ferrite hlau nplaum, AlNiCo thiabSamarium Cobalt: koj puas xav tau ntau tus thwjtim?, nws magnetic kev ua tau zoo heev tshaj ntawm lwm cov hlau nplaum. NdFeB hlau nplaum tuaj yeem nqus tau 640 npaug ntawm qhov hnyav ntawm lawv tus kheej qhov hnyav, yog li NdFeB hlau nplaum feem ntau hu los ntawm cov neeg sab nrauv. Rau cov hlau nplaum muaj zog, cov hlau nplaum muaj zog tuaj yeem sib nqus thiab demagnetized, vim tias cov hlau nplaum nws tus kheej yog los yog ntau dua hlau nplaum. Dab tsi yog vim li cas rau demagnetization ntawm cov hlau nplaum muaj zog qee zaum?
Txawm li cas los xij, nyob rau lub sijhawm ib txwm muaj, peb tseem nyiam AC demagnetization txoj kev, uas yog qhov zoo dua li qhov siab -kub demagnetization txoj kev thiab txoj kev vibration demagnetization thiab muaj kev ua haujlwm siab demagnetization. Nws yog txoj kev siv dav tshaj plaws hauv kev tsim khoom.
High -kub demagnetization txoj kev:
Lub luag haujlwm tseem ceeb ntawm kev ua haujlwm siab -kub demagnetization txoj kev yog muab cov hlau nplaum tso rau hauv qhov siab - qhov kub thiab txias rau cua sov. Tom qab siab -kub kev kho mob, 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 uas tau hloov pauv ntau heev.
Yog li ntawd, txoj kev demagnetization no feem ntau yog siv rau cov hlau nplaum uas tau muab pov tseg thiab rov qab los. Kev ua haujlwm ntawm txoj kev no yog qhov yooj yim heev. Nws vibrates cov hlau nplaum muaj zog heev thiab hnyav. Tom qab kev vibration ua haujlwm, cov qauv sab hauv ntawm cov hlau nplaum hloov pauv, thiab tom qab ntawd cov khoom siv lub cev ntawm cov hlau nplaum hloov pauv. Feem ntau hais lus, txoj kev demagnetization no yog siv. Cov nyhuv tsis zoo, tsuas yog me me ntawm demagnetization tuaj yeem siv tau ib ntus.
Txoj kev demagnetization no yog muab cov hlau nplaum tso rau hauv qhov chaw uas tuaj yeem tsim AC magnetic teb. Tom qab cuam tshuam los ntawm AC magnetic teb, cov qauv sab hauv ntawm cov hlau nplaum yuav cuam tshuam, thiab tom qab ntawd cov nyhuv ntawm demagnetization tuaj yeem ua tiav. Txoj kev no kuj muaj ntau. Txoj kev demagnetization.
