6.Chifukwa chiyani maginito a neodymium ndi okwera mtengo?
Maginito a Neodymium ndi okwera mtengo poyerekeza ndi mitundu ina ya maginito chifukwa cha zinthu zingapo:
Zipangizo zapadziko lapansi zomwe sizipezeka kawirikawiri: Neodymium ndi imodzi mwazinthu zosowa kwambiri padziko lapansi, zomwe sizipezeka kawirikawiri m'nthaka ya dziko lapansi. Kuchita migodi ndi kukonza zinthu zimenezi kungakhale kokwera mtengo, ndipo kuchepa kwa zinthu zimenezi kukhoza kukwera mtengo.
Kupanga: Kapangidwe ka maginito a neodymium ndizovuta ndipo kumaphatikizapo njira zingapo, kuphatikiza kuphatikizira zopangira, mphero, kukanikiza, ndi sintering. Njirazi zimafuna zida zapadera ndi ukadaulo, zomwe zitha kuwonjezera mtengo.
Kufunika kwakukulu: Maginito a Neodymium akufunika kwambiri chifukwa cha mawonekedwe awo apadera, monga mphamvu zawo ndi kukula kwake kochepa. Kufuna kwakukulu kumeneku kumatha kukweza mtengo, makamaka panthawi ya kusokonekera kwa mayendedwe kapena kufunikira kwapadziko lonse lapansi.
Kutulutsa kwa NdFeB
7.Kodi kuyeretsa maginito neodymium maginito?
Kuti muyeretse maginito a neodymium, mutha kutsatira njira zosavuta izi:
1.Sakanizani pang'ono sopo wofatsa ndi madzi ofunda mu mbale kapena sinki.
2.Ikani maginito a neodymium m'madzi a sopo ndikuwasiya kuti alowerere kwa mphindi zingapo.
3.Pezani pang'onopang'ono pamwamba pazigawo ndi burashi yofewa kapena nsalu kuti muchotse dothi kapena zinyalala.
4.Tsukani zozungulira bwino ndi madzi oyera kuti muchotse zotsalira za sopo.
5.Unikani zozungulira ndi nsalu yoyera, yofewa.
Zindikirani: Osagwiritsa ntchito mankhwala owopsa kapena zinthu zonyezimira kuyeretsa maginito a neodymium, chifukwa izi zitha kuwononga pamwamba pazigawozo ndikuwononga maginito ake. Kuonjezera apo, onetsetsani kuti mukugwiritsira ntchito maginito a neodymium mosamala, chifukwa ndi ophwanyika ndipo amatha kusweka kapena kusweka ngati agwetsedwa kapena osayendetsedwa bwino.
8.Kodi kupeza kalasi ya neodymium maginito?
Kuti mupeze giredi ya maginito a neodymium, mutha kupeza kachidindo kosindikizidwa kapena kusindikizidwa pa maginito omwe. Khodi iyi nthawi zambiri imakhala ndi manambala ndi zilembo zomwe zimawonetsa mphamvu ndi kapangidwe ka maginito. Nawa njira zopezera giredi ya maginito a neodymium:
Yang'anani code pa maginito. Khodi iyi nthawi zambiri imasindikizidwa kapena kusindikizidwa pa malo athyathyathya a maginito.
Khodiyo nthawi zambiri imakhala ndi zilembo ndi manambala angapo, monga "N52" kapena "N35EH".
Chilembo choyamba kapena zilembo zimasonyeza momwe maginito amapangidwira. Mwachitsanzo, "N" amaimira neodymium, pamene "Sm" amaimira samarium cobalt.
Nambala yomwe imatsatira chilembo choyamba kapena zilembo zimasonyeza mphamvu yaikulu ya maginito, yomwe ndi muyeso wa mphamvu zake. Chiwerengero chapamwamba, mphamvu ya maginito.
Nthawi zina padzakhala zilembo kapena manambala owonjezera kumapeto kwa kachidindo, zomwe zingasonyeze zina za maginito, monga kukana kwake kutentha kapena mawonekedwe.
Ngati palibe njira yodziwira kuchuluka kwa maginito a neodymium mutha kudziwanso poyesa. Izi ndichifukwa choti maginito a neodymium amasiyanitsidwa ndi maginito a neodymium. Mutha kugwiritsa ntchito mita ya gauss kuyeza kuchuluka kwa maginito a neodymium maginito ndikugwiritsa ntchito tebulo kuti mudziwe kuchuluka kwa maginito a neodymium.
9.Kodi pali malire a kukula kwa maginito a neodymium?
Palibe malire ovuta kuti maginito a neodymium angakhale aakulu bwanji, koma pali malire othandiza omwe amatsimikiziridwa ndi zifukwa zingapo.
Chinthu chimodzi ndi kupezeka kwa zipangizo zapadziko lapansi zomwe zimagwiritsidwa ntchito popanga maginito a neodymium. Zida zimenezi sizipezeka m’nthaka ya dziko lapansi ndipo ndizokwera mtengo kuzikumba ndikuzikonza. Kukula kwa maginito kumachulukirachulukira, momwemonso kuchuluka kwa zinthu zofunika, zomwe zimatha kupanga maginito akuluakulu kukhala okwera mtengo kwambiri.
Chinthu china ndicho kupanga. Kupanga maginito a neodymium kumaphatikizapo njira zingapo, kuphatikiza kuphatikizira zopangira, mphero, kukanikiza, ndi sintering. Njirazi zimafuna zida zapadera komanso ukadaulo, zomwe zimatha kukhala zovuta komanso zokwera mtengo kuti ziwonjezere maginito akuluakulu.
Maginito a Neodymium amathanso kupanga zazikulu kwambiri
Kuphatikiza apo, maginito akuluakulu a neodymium amatha kukhala ovuta kuwagwira ndikuyika ziwopsezo zachitetezo chifukwa cha mphamvu zawo zamaginito. Athanso kukhala osavuta kusweka kapena kusweka chifukwa cha brittleness yawo.
Maginito a neodymium amapangidwa kuchokera ku chisakanizo cha neodymium, chitsulo ndi boron ufa, zomwe zikutanthauza kuti kugawa kwa neodymium mu maginito a neodymium sikuli yunifolomu, ndipo n'zovuta kutsimikizira kuti maginito a neodymium maginito ndi mphamvu yomweyo kulikonse. . Zotsatira zake, maginito akuluakulu a neodymium nthawi zambiri amakhala okwera mtengo kwambiri kuti awonetsetse kuti akugwira ntchito bwino.
0.Is neodymium mwamphamvu maginito mu mawonekedwe ake koyera?
Neodymium palokha si maginito mwamphamvu, chifukwa ndi chitsulo chosowa padziko lapansi chokhala ndi paramagnetic katundu, kutanthauza kuti imakopeka mofooka ndi maginito. Komabe, pamene neodymium pamodzi ndi zinthu zina monga chitsulo ndi boron kulenga aloyi Nd2Fe14B, amene ntchito kupanga neodymium maginito, chifukwa pawiri zimasonyeza wamphamvu kwambiri maginito katundu chifukwa mayikidwe ake atomiki maginito mphindi. Neodymium mu alloy imagwira ntchito yofunika kwambiri pakuthandizira mphamvu ya maginito yamphamvu ya maginito a neodymium.
Chitsanzo chabwino cha izi ndipot maginito. Maginito a mphika ali ndi magawo atatu: mphete yoyika pulasitiki, nyumba yachitsulo ndi maginito a neodymium. Ntchito yayikulu ya mphete ya pulasitiki ndikukonza maginito a neodymium, kotero ndizotheka kuchita popanda mphete yoyika pulasitiki kuti mupulumutse ndalama malinga ndi zomwe kasitomala akufuna. Chifukwa chachikulu chomwe maginito a mphika ali ndi chitsulo chachitsulo ndi zifukwa ziwiri: 1. maginito a neodymium ndi osalimba ndipo chitsulo chachitsulo chimatha kuchiteteza kumlingo wina ndikuwonjezera moyo wa maginito a mphika; 2. maginito a neodymium ndi chitsulo chosungira pamodzi amatha kupanga maginito amphamvu.
Malangizo: Osapeputsa maginito ang'onoang'ono ngati mphika, ndi maginito kuposa momwe mungaganizire.
