Ozibuthe be-Neodymium abahlanganisiwe benziwe ngezinto ezinamandla ze-Nd-Fe-B ezixutshwe ku-epoxy binder. Ingxube icishe ibe ngu-97 vol% kazibuthe ukuya ku-3 vol% epoxy. Inqubo yokukhiqiza ihlanganisa ukuhlanganisa i-Nd-Fe-B powder ne-epoxy binder kanye nokucindezela ingxube emshinini wokunyathelisa nokuphulukisa ingxenye kuhhavini. Njengoba okokusebenza kwakhiwa ngokuminyanisa ukubopha, ubukhulu buvamise ukuhluka .002″ noma kangcono uma ugijima enikeziwe.Izibuthe Ezihlanganisiwe Ezihlanganisiwe Zozibuthe ze-NdFeB zisetshenziselwa kakhulu isikhunta esilula kanye nezakhiwo eziphakeme kazibuthe, izinga lokushisa elizinzile lokusebenza, ukumelana nokugqwala okuhle. Ziyakwazi ukufaka isikhunta nezinye izingxenye.
Inhlanganisela ephelele yenqubo yokujova kanye ne-high-property eyimpushana yomhlaba engavamile yenza kube nokwenzeka ukwakha i-Ndfeb ring magnet eboshwe kalula yesipika. I-Bonded Neodymium Magnets inenzuzo yomumo othuthuke kakhulu uma uqhathaniswa noZibuthe be-Sintered. Uzibuthe udinga ukumbozwa ngongqimba lwe-epoxy emnyama noma empunga noma i-Parylene ukuze uvikeleke ekugqwaleni.
Ozibuthe be-NdFeB abacindezelwe abashisayo bahlukaniswe izinhlobo ezimbili, i-Hot pressed isotropic NdFeB (MQ 2) kanye nozibuthe we-anisotropic we-NdFeb (MQ 3) oshisayo ocindezelwe oshisayo (MQ 3) .Umazibuthe we-NdFeb ocindezelwe oshisayo ukhiqizwa yi-NdFeB magnetic pw der ecishwa ngokushesha ngaphansi kwezinga lokushisa eliphezulu. ngokusebenzisa ukucindezela.Uzibuthe we-anisotropic we-NdFeB ocindezelwe oshisayo ngokuyinhloko uwuzibuthe wendandatho we-anisotropic radially-oriented okhiqizwa ngokucindezelwa nokuguqulwa kwe-extrusion ngokucisha ngokushesha i-NdFeB powder magnetic ngaphansi kwezinga lokushisa eliphezulu.Injection Customized Bonded NdFeB Ring Magnets
Ozibuthe be-neodymium-iron-boron (NdFeB) abahlanganisiwe bangozibuthe abaqinile abasetshenziselwa izinhlelo zokusebenza ezahlukahlukene. I-epoxy coating ivame ukusetshenziselwa omazibuthe be-NdFeB ababoshiwe; i-electroless nickel plating nayo isetshenziselwa ukuvimbela ukugqwala. I-Isotropic bonded NdFeB impahla ingafakwa uzibuthe kunoma iyiphi indlela, noma ngezigxobo eziningi.
I-Bonded Nd-Fe-B impahla iyi-isotropic, ngakho-ke ingenziwa uzibuthe nganoma iyiphi indlela, okuhlanganisa ukuhlelwa kwe-multi-polar. Ngenxa yokuthi impahla iku-epoxy binder, ingenziwa ngomshini emshinini wokugaya noma i-lathe. Kodwa-ke, okubalulekile ngeke kusekele intambo, ngakho-ke izimbobo azikwazi ukuthintwa. Izinto ezihlanganisiwe ze-Nd-Fe-B zivame ukusetshenziselwa ukunciphisa kakhulu usayizi wemiklamo esebenzisa izinto zikazibuthe ze-ceramic. Ukuncishiswa kosayizi okuphawulekayo kungafinyelelwa ngoba impahla icishe iqine ngokuphindwe kathathu kunempahla kazibuthe ye-ceramic. Ngaphezu kwalokho, njengoba ukwaziswa kuyi-isotropic, kungenziwa uzibuthe we-multi-polar, njengephethini ye-NSNS kububanzi obungaphandle bendandatho.
Ozibuthe be-Bonded NdFeB bane-remanence ephezulu, ukuphoqelelwa okuphezulu, umkhiqizo wamandla aphezulu, ukusebenza okuphezulu kanye nenani lentengo, kulula ukucubungula osayizi abahlukahlukene, kanye nokucaciswa okuncane inzuzo. , imikhiqizo ye-elekthronikhi ekhanyayo, nencane.
Ozibuthe be-Bonded NdFeb banamandla kazibuthe aphezulu kunozibuthe ababunjwe ngomjovo, futhi banenzuzo yokuma okuthuthuke kakhulu uma kuqhathaniswa nozibuthe abahlanganisiwe. Ukuphoqwa okuphezulu, umkhiqizo wamandla aphezulu, ukumelana nokugqwala, nokumelana nezinga lokushisa.
I-Bonded neodymium powder isetshenziselwa ukwakha lezi zidonsa. Impushana iyancibilika futhi ihlanganiswe ne-polymer. Izingxenye zibe sezicindezelwa noma zikhishwe ukuze kwakhiwe umkhiqizo. Ozibuthe be-Neodymium abahlanganisiwe bangenziwa uzibuthe babe amaphethini ayinkimbinkimbi ngezigxobo eziningi. Nakuba bebuthakathaka kakhulu kunozibuthe be-Sintered Neodymium, ozibuthe be-Bonded neodymium banikeza ukuguquguquka okukhulu ngokwemimo engenziwa. Futhi zilula kune-Samarium Cobalt, futhi zinezinga lokushisa eliphansi elamukelekayo (ukuphoqelela). Noma kunjalo, banikeza inani elihle kakhulu lezinhlelo zokusebenza ezidinga uzibuthe omncane noma zisebenzisa izindandatho ze-radial.
Isicelo:
Izinsiza Ezizenzakalelayo Zehhovisi, Imishini Kagesi, Izinto ezilalelwayo ezibukwayo, Izinsimbi, izinjini ezincane nemishini yokukala, omakhalekhukhwini, i-CD-ROM, ama-DVD-ROM drive motors, ama-hard disk spindle motors HDD, amanye amamotho ama-micro DC, nezinsimbi ezishintshayo njll.
Izinga Lokushisa Eliphezulu Lokusebenza:
Nakuba izinga lokushisa le-Curie lezinto ezibonakalayo ze-NdFeB licishe libe ngu-310 ºC ku-0% wento ye-cobalt ibe ngaphezu kuka-370 ºC ku-5% cobalt, ukulahlekelwa okuthile okungenakuguqulwa kokuphumayo kungase kulindeleke emazingeni okushisa aphakathi nendawo. Ozibuthe be-Neo baphinde babe ne-Reversible Temperature Coefficient ephezulu ngokumaphakathi ye-Induction enciphisa inani eliphelele likazibuthe njengoba izinga lokushisa likhuphuka. Ukukhethwa kozibuthe be-neo esikhundleni se-SmCo, kuwumsebenzi wezinga lokushisa eliphezulu lohlelo lokusebenza, okukhiphayo kazibuthe ekushiseni okujwayelekile okusebenzayo kanye nenani eliphelele lesistimu.
Ozibuthe be-Neo nabo banemikhawulo ethile ngenxa yokuziphatha kwabo kokugqwala. Esimeni esiswakeme, kunconywa kakhulu ukumboza okokuvikela noma ukucwenga. Izindwangu ezisetshenziswe ngempumelelo zihlanganisa; i-e-coating, i-powder coating, i-nickel plating, i-zinc plating, i-parylene kanye nezinhlanganisela zalezi zingubo.
