✧ Mwachidule
Maginito a NIB amabwera m'makalasi osiyanasiyana, omwe amafanana ndi mphamvu ya maginito awo, kuyambira N35 (yotsika kwambiri komanso yotsika mtengo) mpaka N52 (yamphamvu kwambiri, yokwera mtengo kwambiri komanso yosasunthika). Maginito a N52 ndi pafupifupi 50% yamphamvu kuposa maginito a N35 (52/35 = 1.49). Ku US, ndizofanana kupeza maginito ogula mumtundu wa N40 mpaka N42. Pakupanga voliyumu, N35 imagwiritsidwa ntchito nthawi zambiri ngati kukula ndi kulemera sikuli kofunikira chifukwa ndizotsika mtengo. Ngati kukula ndi kulemera ndizofunikira kwambiri, masukulu apamwamba amagwiritsidwa ntchito. Pali mtengo wa maginito apamwamba kwambiri kotero ndizofala kwambiri kuwona maginito a N48 ndi N50 omwe amagwiritsidwa ntchito popanga motsutsana ndi N52.
✧ Kodi Makalasi Amatsimikiziridwa Bwanji?
Maginito a Neodymium kapena omwe amadziwika kuti NIB, NefeB kapena maginito apamwamba kwambiri ndi maginito amphamvu kwambiri komanso omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi. Ndi mankhwala a Nd2Fe14B, maginito a neo ali ndi mawonekedwe a tetragonal crystalline ndipo makamaka amapangidwa ndi zinthu za neodymium, Iron ndi Boron. Kwa zaka zambiri, maginito a neodymium asintha bwino mitundu ina yonse ya maginito okhazikika kuti agwiritsidwe ntchito mofala mu mota, zamagetsi ndi zida zina zatsiku ndi tsiku. Chifukwa cha kusiyana kwa kufunikira kwa maginito ndi kukoka mphamvu pa ntchito iliyonse, maginito a neodymium amapezeka mosavuta m'makalasi osiyanasiyana. Maginito a NIB amapangidwa molingana ndi zinthu zomwe amapangidwa. Monga lamulo lofunikira, kukweza magiredi, maginito adzakhala amphamvu.
Neodymium nomenclature nthawi zonse imayamba ndi 'N' kutsatiridwa ndi manambala awiri mkati mwa mndandanda wa 24 mpaka 52. Chilembo 'N' m'magiredi a neo magnets chimayimira neodymium pomwe manambala otsatirawa akuyimira mphamvu yayikulu kwambiri yamagetsi enieni. maginito omwe amayezedwa mu 'Mega Gauss Oersteds (MGOe). Mgoe ndiye chizindikiro choyambirira cha mphamvu ya maginito aliwonse a neo komanso kuchuluka kwa maginito opangidwa ndi iyo mkati mwa zida zilizonse kapena kugwiritsa ntchito. Ngakhale mtundu woyambirira umayamba ndi N24 komabe, otsika sakupangidwanso. Momwemonso, ngakhale mphamvu yayikulu yotheka ya NIB ikuyembekezeka kufika ku N64 komabe kuchuluka kwamphamvu kotereku sikunafufuzidwebe pamalonda ndipo N52 ndiye giredi yapamwamba kwambiri yomwe ikupezekapo mosavuta kwa ogula.
Zilembo zina zowonjezera zomwe zikutsatira kalasiyi zimatengera kutentha kwa maginito, kapena kusakhalapo kwake. Kutentha kwapakati ndi Nil-MH-SH-UH-EH. Zilembo zomalizazi zikuyimira kutentha kwambiri komwe kumagwirira ntchito, mwachitsanzo, kutentha kwa Curie komwe maginito angapirire asanathe kutaya mphamvu zake zonse. Maginito akagwiritsidwa ntchito kupitirira kutentha kwa Curie, zotsatira zake zimakhala kutayika kwa zotulutsa, kuchepa kwa zokolola ndipo pamapeto pake demagnetization yosasinthika.
Komabe, kukula kwake ndi mawonekedwe a maginito aliwonse a neodymium amakhalanso ndi gawo lalikulu pakutha kwake kugwira ntchito bwino pakutentha kwambiri. Komanso, chinthu china choyenera kukumbukira ndi chakuti mphamvu ya maginito abwino ndi ofanana ndi chiwerengero, kotero kuti N37 ndi 9% yokha yofooka kuposa N46. Njira yodalirika yowerengera giredi yeniyeni ya neo maginito ndikugwiritsa ntchito makina oyesa ma graph a hysteresis.
AH Magnet ndiwosowa maginito padziko lapansi omwe amagwira ntchito pofufuza, kupanga, kupanga ndi kutumiza maginito apamwamba kwambiri a sintered neodymium iron boron, magiredi 47 a maginito wamba a neodymium, kuyambira N33 mpaka 35AH, ndi GBD Series kuyambira 48SH mpaka 45AH zilipo. Ngati mukufuna zinthu zathu, lemberani ife tsopano!
