Flexible NdFeB hlau nplaum yog ib hom micro-crystalline NdFeB sib tsoo hmoov thiab polymer matrix saj zawg zog hlau nplaum. Nws yog qhov muaj zog tshaj plaws isotropic saj zawg zog hlau nplaum nyob hauv lub ntiaj teb tam sim no. Nws cov khoom siv hluav taws xob sib nqus siab tshaj plaws tau tsim los rau 90kj / cm3 (11.25MGOe), uas yog 5 npaug ntawm lub zog sib nqus ntawm cov kua nplaum thiab ze rau lub zog sib nqus ntawm NdFeB nias. Lub zog sib nqus ntawm kev lag luam loj yog 16 txog 68KJ / m3 (2.0 ~ 8.5MGOe). Microcrystalline magnetic hmoov ua rau nws muaj zog sib nqus, thiab cov roj hmab dag ua rau nws hloov tau, thiab yooj yim rau machined rau hauv cov ntaub ntawv sib nqus sib nqus, sib nqus strips. thiab sib nqus rings thiab lwm yam zoo li cov khoom siv kom tau raws li ntau yam kev xav tau.Yooj yimNdFeBdaim ntawvfeem ntau siv rau hauv cov nas wireless, portable DVDS, me me motors hauv laptop computers, tiaj tus hais lus hauv TV thiab stereo li, thiab tiv thaiv tub sab nyiag.
Qhov zoo
1.Qhov kev ua tau zoo yog nruab nrab ntawm ferrite thiab nruj NdFeB cov hlau nplaum ruaj khov, sau qhov sib txawv ntawm lawv.
2. Nws tuaj yeem tsim cov khoom lag luam nyias nyias ntawm txhua yam duab, thiab cov tuab ntawm cov hlau nplaum tuaj yeem ncav cuag li 0.3mm, uas yog qhov nyuaj rau kev ua tiav nrog rau cov txheej txheem sintering thiab txhaj tshuaj, kom paub txog lub teeb yuag thiab miniaturization ntawm khoom siv.
3. Nws tuaj yeem yooj yim heev los ua kom tag nrho cov radial (kua hluav taws xob) kev taw qhia ntawm cov hlau nplaum.
4. Muab piv nrog cov hlau nplaum nruj, nws muaj cov khoom siv zoo dua qub, muaj kev cuam tshuam zoo thiab tsis yooj yim rau tawg.
5. Nws tuaj yeem muab tso rau hauv cov hlau, tsis yog hlau thiab lwm yam khoom siv molding, kom ua tiav cov khoom sib xyaw.
Yam ntxwv
• Cov khoom sib nqus siab tshaj plaws hauv isotropic flexible magnet, (BH)max{{0}}.0MGO hauv lab thiab (BH)max =2.0-8.5 MGOe hauv kev tsim khoom loj.
• Ua haujlwm kub li ntawm -40 degree mus rau 120 degree
• Kev ruaj ntseg zoo thiab kev ntseeg siab, uas tau ua pov thawj los ntawm kev sim ua haujlwm
• Cov txheej txheem ntau lawm luv dua yam tsis muaj pwm
• Ntau yam duab: ntev thiab nqaim tuav, thaj tsam loj nyias nyias, nyias nplhaib, thiab lwm yam.
• Cov khoom hloov tau zoo, zoo li tsis muaj qhov tawg, tsis muaj chipping (Tsis muaj kab nrib pleb ntawm cov hlau nplaum thaum 1 hli tuab daim ntawv qhwv ib ncig ntawm 10 mm inch mandrel).
• Saj zawg zog magnetizing, qis cogging vim magnetically isotropic yam ntxwv.
