NdFeB muaj kev ua tau zoo heev hauv kev sib koom ua ke, khoom siv hluav taws xob sib nqus, remanence thiab lwm yam "magnetic zog" coefficients:
1. Muaj zog tiv thaiv demagnetization muaj peev xwm, qhov sib xyaw ua ke tuaj yeem ncav cuag SmCo cov hlau nplaum ruaj khov. Nws yog kwv yees li ob zaug ntawm ferrite thiab txog 3-10 zaug ntawm ferrite;
2. Cov cuab yeej thiab cov ntsuas siv NdFeB cov khoom sib nqus muaj peev xwm ntau dua nyob rau hauv lub teeb yuag, thiab cov khoom siv hluav taws xob sib nqus yog 1.5 npaug ntawm SmCo cov hlau nplaum ruaj khov thiab 10 npaug ntawm ferrite.
3. Muaj zog tiv thaiv sab nraud magnetic teb, remanence yog 1.2 npaug ntawm SmCo cov hlau nplaum ruaj khov thiab 3-4 npaug ntawm ferrite.
Yog li ntawd, NdFeB hlau nplaum tau siv dav vim lawv qhov kev sib piv zoo hauv kev sib xyaw ua ke, cov khoom siv hluav taws xob sib nqus, kev rov ua haujlwm thiab lwm yam, thiab tau txais txiaj ntsig zoo "sib nqus huab tais".
Kev ua haujlwm siab NdFeB hlau nplaum yog qhov nyuaj los hloov, nrog rau ob qho tib si kev thov nruj thiab cov yam ntxwv loj hlob sai. Sintered NdFeB hlau nplaum yog hom tseem ceeb. Raws li cov txheej txheem ntau lawm, NdFeB hlau nplaum tuaj yeem muab faib ua peb hom: sintered, bonded thiab kub nias.
1. Sintered NdFeB sib nqus cov ntaub ntawv siv hmoov metallurgy los ua cov ntaub ntawv prefabricated rau hauv cov hmoov zoo, nias rau hauv billets, thiab ces sinter lawv. Nws muaj cov yam ntxwv ntawm cov khoom siv hluav taws xob sib nqus, siab coercive, thiab kev ua haujlwm siab. Nws yog tsuas yog siv nyob rau hauv motors, generators thiab lwm yam teb;
2. Bonded NdFeB hlau nplaum yog cov hlau nplaum ua los ntawm kev sib xyaw NdFeB hlau nplaum hmoov nrog cov ntaub ntawv polymer thiab ntau yam khoom ntxiv, thiab tom qab ntawd siv cov txheej txheem molding xws li molding lossis txhaj tshuaj molding. Kev ua tau zoo ntawm kev sib raug zoo NdFeB tsis zoo li ntawm sintered NdFeB, tab sis nws muaj qhov zoo ntawm cov txheej txheem yooj yim, tsis tshua muaj nqi, me me, siab precision, uniform thiab ruaj khov magnetic teb, thiab lwm yam. Nws yog tsuas yog siv nyob rau hauv cov ntaub ntawv technology, chaw ua hauj lwm. automation, neeg siv khoom siv hluav taws xob thiab lwm yam.
