Cov ntaub ntawv tsim los ntawm ob lossis ntau yam khoom uas muaj cov khoom sib txawv lossis cov txheej txheem sib txawv, ua ke hauv daim ntawv microscopic lossis macroscopic, tuaj yeem hu ua
Rau cov khoom sib xyaw. Piv nrog cov ntaub ntawv homogeneous ib txwm muaj, qhov loj tshaj plaws ntawm cov ntaub ntawv sib xyaw yog tias lawv tuaj yeem ua tiav raws li qhov ua tau zoo ntawm cov khoom.
Tsim nyog tsim, muab kev ua si tag nrho rau qhov zoo ntawm cov khoom, kov yeej qhov tsis txaus ntawm ib qho khoom siv, kom cov khoom sib xyaw tuaj yeem tau txais cov khoom zoo tshaj plaws uas ib qho khoom tsis muaj.
Composite kev ua tau zoo, uas yog, cov ntaub ntawv sib xyaw muaj kev ua tau zoo tsim. Tam sim no, feem ntau cov ntaub ntawv sib xyaw yog cov khoom siv sib xyaw ua ke, uas yog cov yam ntxwv ntawm lub zog tshwj xeeb
Siab tshwj xeeb modulus. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, muaj kev xav tau ntau ntxiv rau cov khoom siv ua haujlwm thiab kev ua haujlwm siab dua. Kev siv cov khoom sib xyaw
Kev tshawb fawb txog cov khoom siv sib xyaw ua haujlwm tshiab raws li cov hauv paus ntsiab lus thiab cov txheej txheem ntawm cov ntaub ntawv tau dhau los ua ib qho tseem ceeb hauv kev txhim kho cov khoom siv. Bonded NdFeB hlau nplaum
Nws yog ib yam khoom sib nqus sib nqus. Nws yog tsim los ntawm cov hlau nplaum NdFeB hmoov thiab tsis yog hlau nplaum.
Kev tshawb fawb ntawm ntau lub ntsiab lus sib txuas ua ke NdFeB hlau nplaum
Nyob rau hauv xyoo tas los no, kev tshawb fawb ntawm ntau lub ntsiab lus sib txuas cov hlau nplaum tau pib nyiam cov kws tshawb fawb hauv tsev thiab txawv teb chaws. Multi-element composite bonded magnets xa mus rau cov hlau nplaum uas muaj
Muaj ntau tshaj ob qhov sib txawv sib nqus hmoov. Txij li thaum sib txuas NdFeB hlau nplaum hmoov muaj qhov ua tau zoo-tus nqi piv, lwm cov hmoov sib nqus sib xyaw nrog NdFeB sib nqus hmoov.
Composite bonded NdFeB hlau nplaum ua tom qab sib tov tau nyiam ntau xim. Cov txheej txheem sib xyaw suav nrog kev sib xyaw ua ke ntawm NdFeB sib nqus hmoov thiab ferrite magnetic hmoov.
Qhov sib xyaw ntawm ceev quenching NdFeB sib nqus hmoov thiab samarium cobalt hmoov, cov khoom sib xyaw ntawm isotropic thiab anisotropic NdFeB hmoov. Composite bonded NdFeB tuaj yeem siv rau hauv
Muaj kev cia siab rau kev tawg ntawm cov hauv qab no:
2. Tus nqi qis. Txij li thaum tus nqi ntawm Rapidly-quenched neodymium hlau boron mus tas li hlau nplaum hmoov, tshwj xeeb tshaj yog MQ magnetic hmoov, kuj tseem kim, nws muaj kev cuam tshuam zoo rau kev sib txuas ntawm NdFeB.
Boron yog dav siv, siv kev sib xyaw ntawm ferrite magnetic hmoov thiab ceev quenching hmoov, los yog ua ke ntawm cov nqi qis magnetic hmoov thiab Rapidly-quenched neodymium hlau boron mus tas li hlau nplaum hmoov kom tau txais cov nqi qis.
Tus nqi sib raug zoo NdFeB hlau nplaum.
2. Tsawg kub coefficient. Siv cov txiaj ntsig kub ntawm cov hmoov sib nqus sib txawv hauv cov hlau nplaum sib xyaw ua ke thiab kev sib xyaw ntawm anisotropic magnetic hmoov thiab cov hlau nplaum isotropic.
Cov txiaj ntsig kub ntawm cov hmoov tuaj yeem txo qhov kub coefficient. Piv txwv li, Yoshihiko Matsuyama muab anisotropic ferrite nrog
Qhov kub coefficient ntawm cov hlau nplaum sib txuas uas tau npaj los ntawm kev sib xyaw NdFeB hmoov thiab isotropic NdFeB hlau nplaum hmoov tuaj yeem txo tau rau 0.098 feem pua / degree, qhia txog qee yam Prospects.
3.Magnetic kev ua tau zoo tsim. Nyob rau hauv kev npaj ntawm bonded NdFeB hlau nplaum, ferrite thiab lwm yam hlau nplaum yog ntxiv thiab tuaj yeem npaj los ntawm kev tsim qauv.
Nws tuaj yeem tsim cov hlau nplaum sib nqus nrog cov khoom siv hluav taws xob sib nqus hloov tsis tu ncua hauv thaj tsam ntawm 2 ~ 12MGOe, tshwj xeeb tshaj yog cov khoom siv hluav taws xob sib nqus hauv thaj tsam ntawm 4 ~ 8MGOe.
Qhov sib nqus kev ua tau zoo ntawm cov hlau nplaum yog nruab nrab ntawm sintered ferrite thiab bonded NdFeB, thiab nws cov nqi qis dua li ntawm ib qho kev sib koom ua ke NdFeB. Nws tuaj yeem ua tau raws li qee qhov kev xav tau Tsim qauv rau qee lub sijhawm.
