  • Sintered NdFeB Magnet

    Incazelo emfushane:

    Imagnethi yeNeodymium (NdFeB) - uzibuthe womhlaba ongajwayelekile owakhiwe nge-neodymium, i-iron ne-boron, iChina yaqala ukumba izimayini zasekhaya lezi ngawo-1980. Omazibuthe be-NeFeB bacindezelwe futhi ba-sintered endaweni evikelayo. Uma izinqubo zingalawulwa kahle, kuzoholela kukhubazeko lwekhwalithi ngenxa yokugqwala. Ngesikhathi SESIKHATHI, sizikhipha ngaphandle kwalezi zinkinga zisuka nje ngokuthwala izilawuli zekhwalithi futhi sibheka njengengxenye ebaluleke kakhulu, hhayi kumkhiqizo wokugcina kuphela kodwa futhi nangesikhathi sezinqubo ezibucayi esizeni.

     Qaphela:
    Ngaphansi kokushisa okusebenzayo okungu-20 ℃ ± 2 ℃, ngenhla kwemingcele kazibuthe nezakhiwo zomzimba kuyahlolwa, ngokulahlekelwa okungenakugwenywa kwamandla kazibuthe okungekho ngaphezu kwama-5%. .


    Inzuzo:

    Izici zala magnet ziphakeme kakhulu kunezendabuko futhi okwamanje zinamandla kakhulu ekusetshenzisweni. Ukuphakama kwabo

    ukuphoqelela kanye nokuhlala okuphezulu kuvumela ukwakhiwa okusha kanye nethuba lokukhulisa amandla kazibuthe wokusebenzisa lapho isikhala sinqunyelwe

    noma lapho kudingeka khona amandla kazibuthe aqinile.

    NdFeB odonsa basengozini kakhulu ukugqwala. Ngakho-ke dinga ingubo yokuvikela indawo. Ukusetshenziswa NdFeB uzibuthe kunemibandela

    ngezinga lokushisa ebangeni elikhulu eligijima lisuka ku-80ºC liye ku-230ºC. Futhi isebenza ezingeni lokushisa elingaphansi kuka-0 ℃.

    Isicelo:
    Ama-Neodymium odonsa asetshenziswa njengezinhlobo ezahlukahlukene zamalensi kazibuthe wokugxila, ukuphambuka kwezinhlayiya ezikhokhisiwe ku-elekthronikhi, amasistimu amabhuleki,

    i-drip, inzwa, amandla kazibuthe ku-rotor nama-motors amancane, kanye nensimu yesayensi, ezemithi (i-tomography, ama-spectrometer we-NMR), njll.

     

    Namuhla, odonsa be-NdFeB basetshenziswa ngobuningi emhlabeni wonke. Ukwenziwa kwale nto akukapheli; isizungu

    futhi amandla okuphoqelela ensimu akhula ngokuqhubekayo. Amandla aphezulu kazibuthe weNdFeB asho ukuthi kungakhiwa izinjini nezinzwa

    ihlale incanyana - futhi lokhu kusho ukwanda kokusebenza kahle. Ukuthuthuka okuqhubekayo kwenza le nto ethokozisayo ikwazi ukuphikisana-

    yethulwe ezindaweni ezintsha.

    Wonke amanani ashiwo anqunywa kusetshenziswa amasampuli ajwayelekile ngokwe-IEC 60404-5. Ukucaciswa okulandelayo kusebenza njengamanani ayisethenjwa futhi

    kungahluka. Ngeminye imininingwane sicela uxhumane nonjiniyela bethu bohlelo lokusebenza.
