Txawm hais tias muaj coob tus neeg paub txog cov hlau nplaum ruaj khov, lawv tsis paub tias cov hlau nplaum tuaj yeem muab faib ua ntau hom. Tsis tas li ntawd, "cov hlau nplaum zoo tib yam" thiab "neodymium hlau boron haib hlau nplaum"
1. Raws li cov khoom siv, cov hlau nplaum tuaj yeem muab faib ua neodymium hlau boron hlau nplaum, ferrite hlau nplaum, samarium cobalt hlau nplaum thiab alnico hlau nplaum. Ntawm lawv, qhov nrov tshaj plaws yog NdFeB hlau nplaum, uas yog hu ua "King of Magnets" vim nws lub zog sib nqus super.
2. Raws li lawv cov khoom sib nqus, lawv tuaj yeem muab faib ua cov hlau nplaum ruaj khov thiab cov hlau nplaum zoo tib yam.
3. Raws li lub zog sib nqus, nws tuaj yeem muab faib ua cov hlau nplaum muaj zog thiab cov hlau nplaum zoo tib yam.
Yog li dab tsi yog qhov txawv ntawm cov hlau nplaum zoo tib yam thiab cov hlau nplaum neodymium?
1. Qhov kub thiab txias tsis kam: Qhov kub thiab txias ntawm Curie ntawm NdFeB hlau nplaum yog siab dua li cov hlau nplaum zoo tib yam. Txawm hais tias siv cov khoom siv hlau nplaum muaj zog, nws qhov kev ua tau zoo dua li cov hlau nplaum zoo tib yam, yog li qhov kawg kub ntawm cov hlau nplaum muaj zog nws tus kheej tuaj yeem nce siab heev. Hauv kev lag luam kev lag luam, cov tshuab tuaj yeem ua haujlwm ntawm qhov kub thiab txias.
2. Hardness: Vim hais tias NdFeB hlau nplaum nce qhov ntom ntawm cov ntsiab lus tsis tshua muaj, lawv hardness yuav siab dua li cov hlau nplaum zoo tib yam. Yog li ntawd, thaum siv, kev tawg ntawm cov hlau nplaum vim kev sib tsoo yog heev zam, thaum cov hlau nplaum zoo tib yam tsis yooj yim thiab lawv cov tsos yuav xeb mus ntev.
3. Cov hlau nplaum muaj zog: Cov hlau nplaum feem ntau nyob rau hauv kev ua lag luam nyob ntawm cov nyiaj npib lawv tuaj yeem nqus tau. Tab sis NdFeB cov hlau nplaum muaj zog tuaj yeem nqus tau 640 npaug ntawm lawv tus kheej qhov hnyav, thiab nws yog qhov xav tau tias cov hlau nplaum muaj zog heev. Yog li thaum tuaj rau hauv kev sib cuag nrog cov hlau nplaum muaj zog, yuav tsum tau saib xyuas kom tsis txhob raug ntes hauv lawv.
4. Nqe: Txawm hais tias cov hlau nplaum ntawm NdFeB hlau nplaum muaj zog heev, nws tus nqi yog ncaj qha proportional rau nws tus kheej.
Txhua yam, tseem muaj qhov sib txawv loj ntawm NdFeB hlau nplaum thiab cov hlau nplaum zoo tib yam. NdFeB hlau nplaum feem ntau yog siv hauv hluav taws xob thiab lwm yam lag luam.
