Maginito a Sintered Neodymium
Sintered Neodymium Magnetndi maginito amphamvu amasiku ano, omwe samangokhala ndi mikhalidwe yabwino kwambiri monga kukhazikika kwakukulu, kukakamiza kwambiri, mankhwala opangira mphamvu zamagetsi, komanso chiŵerengero chamtengo wapatali chamtengo wapatali komanso ndi chosavuta kupanga mawonekedwe ndi makulidwe osiyanasiyana, makamaka oyenera mphamvu zazikulu komanso malo okwera maginito, komanso zinthu zingapo zosinthira zazing'ono komanso zopepuka.
Maginito a Sintered Neodymium amagwiritsidwa ntchito kwambiri pamagalimoto (magalimoto amagetsi, chiwongolero chamagetsi, masensa, ndi zina zambiri), kupanga magetsi amphepo, makampani azidziwitso (ma hard disk drive, optical disk drives), zamagetsi zamagetsi (mafoni am'manja, makamera a digito), apanyumba. zida (zosinthira pafupipafupi mpweya, mafiriji, ndi makina ochapira), ma elevator linear motors, makina ojambulira maginito a nyukiliya, ndi zina zotero. Pakupanga mwanzeru, kuyendetsa mwanzeru, koimiridwa ndi maloboti.Mapulogalamum'madera monga ntchito zanzeru zikuwonjezeka.
Maginito a Neodymium Ogwirizana
Bonded Neodymium Magnet ndi mtundu wa zinthu zophatikizika za maginito okhazikika opangidwa mwa kuphatikiza mwachangu nanocrystalline neodymium chitsulo boron maginito ufa wokhala ndi polima wapamwamba (monga thermosetting epoxy resin, thermoplastic engineering plastics, etc.) monga chomangira, chogawidwa kukhalaMaginito Ophatikizidwa a NeodymiumndiMaginito Ojambulira a Neodymium.Ili ndi kulondola kwapamwamba kwambiri, kufananiza kwabwino kwa maginito, komanso kusasinthasintha, ndipo imatha kupangidwa kukhala mawonekedwe ovuta omwe ndi ovuta kuwapeza pamagetsi a sintered neodymium ndipo ndiosavuta kuphatikiza ndi zitsulo zina kapena pulasitiki kuti apange.Maginito a Bonded Neodymium alinso ndi njira zosiyanasiyana za magnetization, kuchepa kwa eddy pano, komanso kukana kwamphamvu kwa dzimbiri.
Maginito a Bonded Neodymium amagwiritsidwa ntchito kwambiri m'mafakitale aukadaulo wazidziwitso monga ma hard drive apakompyuta ndi ma optical disc drive spindle motors, makina osindikizira/makopera, ndi maginito odzigudubuza, komanso zida zoyendetsera ndi zowongolera pazida zopulumutsa mphamvu zapakhomo ndi zida zamagetsi zamagetsi.Kugwiritsa ntchito kwawo m'mamotor ang'onoang'ono ndi apadera ndi masensa a magalimoto atsopano amphamvu pang'onopang'ono akukhala msika wodziwika bwino.
Kufotokozera Mphamvu
Neodymium ndi antiferromagnetic chitsulo chomwe chimawonetsa mawonekedwe a maginito akakhala oyera, koma pa kutentha kosachepera 19 K (254.2 °C; 425.5 °F).Mankhwala a Neodymium okhala ndi zitsulo zosinthira ferromagnetic monga chitsulo, okhala ndi kutentha kwa Curie kuposa kutentha kwa chipinda, amagwiritsidwa ntchito kupanga maginito a neodymium.
Mphamvu za maginito a Neodymium ndizophatikiza zinthu zosiyanasiyana.Chofunika kwambiri ndipamwamba kwambiri uniaxial magnetocrystalline anisotropy ya tetragonal Nd2Fe14B crystal structure (HA 7 T - maginito mphamvu H mu mayunitsi A/m motsutsana maginito mphindi Am2).Izi zikuwonetsa kuti kristalo wa chinthucho imapanga maginito motsatira njira ina ya kristalo koma zimakhala zovuta kwambiri kuti maginito alowe mbali zina.Maginito a neodymium magnet alloy, monga maginito ena, amapangidwa ndi njere za microcrystalline zomwe zimapangidwira molumikizana ndi mphamvu ya maginito kotero kuti maginito ake onse amaloza mbali imodzi.Pawiriyi imakhala ndi mphamvu yokakamiza kwambiri, kapena kukana demagnetization, chifukwa cha kukana kwa crystal lattice kusintha komwe kumayendera maginito.
Chifukwa lili ndi ma elekitironi anayi osaphatikizidwa mu kapangidwe kake ka ma elekitironi poyerekeza ndi (pafupifupi) atatu muchitsulo, atomu ya neodymium imatha kukhala ndi mphindi yayikulu ya dipole.Ma electron osaphatikizidwa mu maginito omwe amayenderana kuti ma spins awo ayang'ane mbali imodzi amapanga mphamvu ya maginito.Izi zimabweretsa mphamvu maginito machulukitsidwe kwa Nd2Fe14B kuphatikiza (Js 1.6 T kapena 16 kG) ndi mmene yotsalira maginito 1.3 teslas.Chotsatira chake, gawo la maginitoli limatha kusunga mphamvu zambiri za maginito (BHmax 512 kJ / m3 kapena 64 MGOe), monga mphamvu yamphamvu kwambiri yofanana ndi Js2.
Mphamvu ya maginito iyi imakhala mozungulira nthawi 18 ndi voliyumu ndi nthawi 12 mokulira kuposa "nthawi zonse"maginito. Samarium cobalt (SmCo), woyamba malonda likupezeka osowa-lapansi maginito, ali mlingo m'munsi mwa mbali ya maginito mphamvu imeneyi kuposa NdFeB kasakaniza wazitsulo.Maonekedwe a maginito a Neodymium amakhudzidwa kwenikweni ndi mawonekedwe a alloy, kupanga, ndi kapangidwe kake.
Maatomu achitsulo ndi kuphatikiza kwa neodymium-boron amapezeka m'magulu ena mkati mwa Nd2Fe14B crystal structure.Ma diamagnetic boron maatomu amalimbikitsa mgwirizano kudzera m'maubwenzi olimba koma samathandizira mwachindunji ku maginito.Maginito a Neodymium ndi otsika mtengo kuposa maginito a samarium-cobalt chifukwa cha kuchepa kwapadziko lapansi komwe kumakhala kochepa kwambiri (12% ndi voliyumu, 26.7% ndi kulemera), komanso kupezeka kwa neodymium ndi chitsulo poyerekeza ndi samarium ndi cobalt.
