Momwe maginito a neodymium amapangidwira

Tifotokoza mmeneMaginito a NdFeBamapangidwa ndi kufotokoza kosavuta. Maginito a neodymium ndi maginito osatha opangidwa kuchokera ku aloyi ya neodymium, chitsulo, ndi boron kuti apange Nd2Fe14B tetragonal crystalline structure. Maginito a sintered neodymium amapangidwa ndi kutentha kwa vacuum osowa kwambiri padziko lapansi ngati zinthu zopangira mu ng'anjo. Pambuyo kupeza zipangizo, tidzachita 9 masitepe kuti NdFeB maginito ndipo potsiriza kutulutsa zomalizidwa.

Konzani zipangizo zochitira, kusungunuka, mphero, kukanikiza, sintering, Machining, plating, magnetization ndi kuyendera.

Konzani zida zochitira

The mankhwala pawiri mawonekedwe a neodymium maginito ndi Nd2Fe14B.

maginito zambiri Nd ndi B wolemera, ndi maginito yomalizidwa zambiri amakhala malo nonmagnetic wa Nd ndi B mu njere, amene ali kwambiri maginito Nd2Fe14B. mbewu. Zinthu zina zingapo zosowa zapadziko lapansi zitha kuwonjezeredwa kuti zilowe m'malo mwa neodymium: dysprosium, terbium, gadolinium, holmium, lanthanum, ndi cerium. Mkuwa, cobalt, aluminiyamu, gallium ndi niobium zitha kuwonjezeredwa kuti zithandizire zina za maginito. Ndizofala kugwiritsa ntchito Co ndi Dy pamodzi. Zinthu zonse zopangira maginito a kalasi yosankhidwa zimayikidwa mu ng'anjo ya vacuum induction, kutenthedwa ndikusungunuka kuti apange zinthu za alloy.

Kusungunuka

Zopangira ziyenera kusungunuka mu ng'anjo yovumbulutsidwa kuti ipange aloyi ya Nd2Fe14B. Chogulitsacho chimatenthedwa ndikupanga vortex, zonse pansi pa vacuum kuteteza kuipitsidwa kuti zisalowe. Chomaliza cha sitepe iyi ndi pepala lopangidwa ndi riboni (SC sheet) lopangidwa ndi makristalo a yunifolomu a Nd2Fe14B. Kusungunulaku kuyenera kuchitika kwakanthawi kochepa kuti tipewe makutidwe ndi okosijeni ochulukirapo a zitsulo zosowa zapadziko lapansi.

Kugaya

Njira ya 2-step mphero imagwiritsidwa ntchito popanga. Gawo loyamba, lotchedwa hydrogen detonation, limakhudza zomwe zimachitika pakati pa haidrojeni ndi neodymium ndi aloyi, kuswa ma flakes a SC kukhala tinthu tating'onoting'ono. Gawo lachiwiri, lotchedwa jet mphero, limatembenuza tinthu ta Nd2Fe14B kukhala tinthu tating'onoting'ono, toyambira 2-5μm. Jet mphero amachepetsa zomwe zimatulukapo kukhala ufa wa tinthu tating'ono kwambiri. Wapakati tinthu kukula ndi mozungulira 3 microns.

Kukanikiza

NdFeB ufa ndi mbamuikha mu olimba mu mawonekedwe ankafuna mu mphamvu maginito. Cholimba choponderezedwa chidzapeza ndikusunga mawonekedwe okonda maginito. Mu njira yotchedwa kufa-upsetting, ufawo umakanikizidwa kukhala cholimba mu kufa pafupifupi 725 ° C. Cholimbacho chimayikidwa mu chikombole chachiwiri, chomwe chimakanikizidwa kukhala chotambalala, pafupifupi theka la kutalika kwake koyambirira. Izi zimapangitsa kuti maginito omwe amawakonda agwirizane ndi njira ya extrusion. Pamawonekedwe ena, pali njira zomwe zimaphatikizapo zomangira zomwe zimapanga mphamvu ya maginito pakukanikiza kuti tigwirizane ndi tinthu tating'onoting'ono.

Sintering

Zoponderezedwa za NdFeB zolimba ziyenera kusiyidwa kuti zipange midadada ya NdFeB. Zinthuzo zimapanikizidwa pa kutentha kwakukulu (mpaka 1080 ° C) pansi pa malo osungunuka a zinthuzo mpaka tinthu tating'ono tigwirizane. Njira yopangira sintering imakhala ndi masitepe atatu: dehydrogenation, sintering ndi tempering.

Machining

Maginito a sintered amadulidwa mu mawonekedwe omwe amafunidwa ndi kukula kwake pogwiritsa ntchito njira yopera. Pang'ono ndi pang'ono, mawonekedwe ovuta omwe amatchedwa mawonekedwe osakhazikika amapangidwa ndi magetsi otulutsa magetsi (EDM). Chifukwa cha kukwera mtengo kwa zinthu, kutayika kwa zinthu chifukwa cha makina kumachepetsedwa. Huizhou Fullzen Technology ndiyabwino kwambiri pakupanga maginito osakhazikika.

Kupaka / Kupaka

Uncoated NdFeB ndi dzimbiri kwambiri ndipo amataya maginito mwamsanga pamene chonyowa. Chifukwa chake, maginito onse ogulitsa a neodymium amafuna zokutira. Maginito pawokha amakutidwa m'magulu atatu: faifi tambala, mkuwa ndi faifi tambala. Kuti mumve zambiri za zokutira, chonde dinani "Contact Us".

Magnetization

Maginito amayikidwa pamalo omwe amawonetsa maginito ku mphamvu ya maginito yamphamvu kwambiri kwa nthawi yochepa. Kwenikweni ndi koyilo yayikulu yokulungidwa mozungulira maginito. Zipangizo zamaginito zimagwiritsa ntchito mabanki a capacitor ndi ma voltages okwera kwambiri kuti apeze mphamvu yamphamvu mu nthawi yochepa.

Kuyendera

Yang'anani mtundu wa maginito obwera chifukwa cha mawonekedwe osiyanasiyana. Pulojekiti yoyezera pakompyuta imatsimikizira kukula kwake. Makina oyezera makulidwe a zokutira pogwiritsa ntchito ukadaulo wa X-ray fluorescence amatsimikizira makulidwe a zokutira. Kuyesa pafupipafupi muzakudya zopopera mchere komanso kuyezetsa zophikira kumatsimikiziranso momwe zokutirazo zimagwirira ntchito. Mapu a hysteresis amayesa kupindika kwa BH kwa maginito, kutsimikizira kuti ali ndi maginito mokwanira, monga momwe amayembekezerera gulu la maginito.
