Neodymium Iron Boron Magnets: Ua kom cov thev naus laus zis siab thiab cov cuab yeej ua tau zoo

Neodymium hlau boron (NdFeB) hlau nplaum yog cov khoom siv hlau nplaum ruaj khov tshaj plaws uas muaj hnub no. Lawv yog tsim los ntawm neodymium, hlau, boron thiab lwm yam tsis tshua muaj lub ntiaj teb, thiab muab lub zog sib nqus siab tshaj plaws ntawm tag nrho cov hlau nplaum ruaj khov. NdFeB hlau nplaum tau ua rau txoj kev loj hlob ntawm lub zog loj thiab lub zog muaj zog thiab lub tshuab hluav taws xob, ua rau lawv siv dav hauv ntau yam lag luam.

Hauv kev lag luam automotive, NdFeB hlau nplaum feem ntau yog siv rau hauv lub cev muaj zog rau lub tsheb fais fab fais fab, lub tshuab hluav taws xob, lub tshuab hluav taws xob tiv thaiv, thiab lwm yam khoom siv hluav taws xob hauv tsheb. Lawv pab txhim kho lub zog ceev thiab kev ua haujlwm ntawm cov tshuab tsheb thaum txo qhov loj thiab qhov hnyav. NdFeB hlau nplaum kuj tseem siv tau ntau yam hauv hybrid thiab hluav taws xob tsheb xws li traction motors, generators, roj teeb thiab roj teeb tswj systems.

Hauv kev lag luam neeg hlau, NdFeB hlau nplaum muab lub zog sib nqus tsim nyog los pab kom muaj kev txav ntawm cov caj npab, tes, thiab cov neeg ua haujlwm. Lawv yog ib qho tseem ceeb rau kev tsim kom muaj kev sib haum xeeb tsis tau muaj zog servomotors thiab cov actuators siv nyob rau hauv industrial robots, kho mob robots, drone motors, thiab lwm yam kev tswj cov lus tsa suab uas yuav tsum tau ceev teb, siab torque, thiab qhov chaw raug.

NdFeB hlau nplaum ua lub luag haujlwm tseem ceeb hauv lub zog tsim hluav taws xob. Lawv siv nyob rau hauv high-ceev generators los hloov txhua yam zog los ntawm cua, hydroelectric thiab tidal zog mus rau hauv hluav taws xob zog rau lub hwj chim daim phiaj. Lawv lub zog sib nqus siab ua rau cov khoom siv hluav taws xob muaj txiaj ntsig thiab lub teeb yuag tsim nyog rau kev tsim hluav taws xob tauj dua tshiab. NdFeB hlau nplaum kuj tseem siv rau hauv electromagnetic railguns thiab fusion reactors tam sim no nyob rau hauv txoj kev loj hlob.

Lwm daim ntawv thov ntawm NdFeB hlau nplaum muaj xws li sib nqus resonance imaging (MRI), sib nqus ntim hauv nuclear fusion, hluav taws xob khoom siv xws li hard disk drives, headphones, thiab sib nqus fasteners. Lawv pab kom miniaturization thiab txhim kho kev ua tau zoo ntawm cov thev naus laus zis nrog lawv cov khoom muaj zog sib nqus.

Hauv cov ntsiab lus, NdFeB cov hlau nplaum ruaj khov tau dhau los ua cov khoom tseem ceeb rau cov thev naus laus zis siab thiab cov cuab yeej ua haujlwm siab thoob plaws kev lag luam loj. Lawv lub zog sib nqus tshwj xeeb, ua haujlwm ntev thiab ua haujlwm rau demagnetization ua rau lawv haum rau ntau hom kev siv uas xav tau lub zog loj, kev tswj xyuas qhov tseeb, qhov loj me thiab kev ua haujlwm tau zoo. Kev tshawb fawb txuas ntxiv thiab kev txhim kho ntawm neodymium hlau nplaum thev naus laus zis yuav txuas ntxiv nthuav lawv cov ntawv thov kev lag luam hauv xyoo tom ntej.
