Ntiv nplhaib NdFeB hlau nplaum yog ib hom hlau nplaum ruaj khov uas tau siv dav hauv ntau yam kev lag luam, los ntawm cov khoom siv hluav taws xob mus rau lub zog tauj dua tshiab thiab dhau mus. Cov hlau nplaum no yog tsim los ntawm kev sib xyaw tshwj xeeb ntawm neodymium, hlau, thiab boron, thiab lawv muaj ntau qhov zoo dua lwm hom hlau nplaum.
Ib qho txiaj ntsig tseem ceeb ntawm lub nplhaib NdFeB hlau nplaum yog lawv lub zog zoo kawg. Cov hlau nplaum no yog qee qhov muaj zog tshaj plaws ntawm kev ua lag luam, nrog cov khoom siv hluav taws xob siab tshaj plaws uas yog ob peb zaug siab dua li cov hlau nplaum ferrite. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj kev sib nqus siab, xws li hauv cov motors, generators, thiab magnetic resonance imaging (MRI) machines.
Lwm qhov zoo ntawm lub nplhaib NdFeB hlau nplaum yog lawv qhov loj me thiab cov duab. Cov hlau nplaum no tuaj yeem tsim nyob rau hauv ntau qhov ntau thiab tsawg, nrog rau cov nplhaib, discs, lub tog raj kheej, thiab cov blocks, uas ua rau lawv muaj ntau yam thiab hloov tau rau ntau daim ntawv thov. Lawv kuj yog lub teeb yuag thiab yooj yim los tuav, uas ua rau lawv muaj kev xaiv nrov rau ntau daim ntawv thov kev lag luam thiab kev tshawb fawb.
Ntxiv rau lawv lub zog thiab ntau yam, lub nplhaib NdFeB hlau nplaum kuj tseem tiv taus demagnetization. Qhov no txhais tau hais tias lawv tuaj yeem tswj hwm lawv cov khoom sib nqus hauv lub sijhawm thiab nyob rau hauv ib puag ncig ib puag ncig, suav nrog qhov kub thiab txias thiab muaj zog electromagnetic tawg. Qhov no ua rau lawv muaj kev ntseeg siab thiab ruaj khov rau ntau daim ntawv thov xav tau.
Zuag qhia tag nrho, nplhaib NdFeB hlau nplaum yog ib qho zoo heev thiab muaj txiaj ntsig thev naus laus zis uas pab txhawb kev tsim kho tshiab thiab kev vam meej hauv ntau thaj chaw. Lawv lub zog, ntau yam, thiab kav ntev ua rau lawv muaj kev xaiv nrov rau ntau qhov kev lag luam, thiab peb tuaj yeem cia siab tias yuav pom kev nce qib ntxiv hauv cov thev naus laus zis no xyoo tom ntej.
