Nyob rau hauv lub ntiaj teb no ntawm hlau nplaum, NdFeB hlau nplaum thiab ferrite hlau nplaum dominate, muab superior sib nqus zog thiab suav tsis tau daim ntaub ntawv. Cov hlau nplaum muaj zog no tau hloov ntau yam kev lag luam, los ntawm cov khoom siv hluav taws xob thiab hluav taws xob txuas ntxiv mus rau kev thauj mus los thiab kev kho mob. Cov kab lus no yuav siv sij hawm tob tob rau hauv cov khoom, kev tsim khoom, kev siv, thiab kev nce qib zoo siab ntawm NdFeB thiab ferrite hlau nplaum, qhia txog lawv qhov chaw tseem ceeb hauv kev siv tshuab niaj hnub no.
NdFeB hlau nplaum: Qhov chaw yug ntawm magnetic forceNdFeB hlau nplaum, tseem hu ua neodymium hlau nplaum, yog cov hlau nplaum ruaj khov uas muaj zog tshaj plaws, muab cov hlau nplaum tsis sib haum. Ua los ntawm neodymium, hlau, thiab boron, cov hlau nplaum no muaj lub zog loj heev, ua rau lawv tsim cov hlau nplaum muaj zog. Nrog lawv qhov loj me thiab lub zog zoo dua, NdFeB hlau nplaum tau hloov pauv ntau yam kev siv, suav nrog lub tshuab hluav taws xob, cov neeg hais lus, sib nqus sib nqus, thiab cov tshuab magnetic resonance imaging (MRI).
NdFeB hlau nplaum tsim txheej txheem: Kev tsim cov hlau nplaum NdFeB koom nrog txoj kev tsim khoom thiab kev tsim khoom. Thawj kauj ruam yog tsim cov khoom siv raw hauv cov hmoov nplej los ntawm cov txheej txheem melting, ua raws li kev sib tsoo thiab annealing los txhim kho cov hlau nplaum hlau nplaum. Lub resulting hmoov yog nias rau hauv pwm thiab sintered ntawm qhov kub thiab txias los tsim ib qho khoom hlau nplaum. Tom qab sintering, cov hlau nplaum yog machined kom tau qhov xav tau cov duab thiab loj. Thaum kawg, kev kho deg xws li txheej lossis plating yog siv los tiv thaiv cov hlau nplaum los ntawm kev xeb thiab txhim kho nws cov kav ntev.
Ferrite Magnets: Versatile Workhorse Ferrite hlau nplaum, tseem hu ua cov hlau nplaum ceramic, muaj zog sib nqus qis dua piv rau NdFeB hlau nplaum tab sis muaj lwm yam zoo xws li kev ua haujlwm siab corrosion thiab kub tsis kam. Cov hlau nplaum no yog tsim los ntawm kev sib xyaw ntawm cov hlau oxide thiab barium carbonate lossis strontium carbonate. Txawm hais tias lawv lub zog sib nqus qis dua, cov hlau nplaum ferrite tau siv dav hauv ntau daim ntawv thov vim lawv cov txiaj ntsig zoo, kev ruaj ntseg zoo, thiab ua haujlwm rau demagnetization. Cov ntawv thov rau cov hlau nplaum ferrite muaj xws li cov hlau nplaum tub yees, cov neeg hais lus, cov hlau nplaum sib nqus, thiab cov hlau nplaum sib nqus.
