Magnets Neodymium-ku-xidhan waxa laga sameeyay walaxda Nd-Fe-B ee xoogga badan oo lagu dhex daray binder epoxy. Isku darka ayaa ah qiyaastii 97 vol% maadada magnet ilaa 3 vol% epoxy. Habka wax soo saarka ayaa ku lug leh isku-darka budada Nd-Fe-B iyo isku-darka epoxy-ga iyo isku-buufinta isku dhafka saxaafadda iyo daawaynta qaybta foornada. Tan iyo maaddada la sameeyay by isku xidhka riixo, cabbirada sida caadiga ah kala duwan yihiin .002 "ama ka wanaagsan ee orod siiyey. The Bonded cadaadis Molded NdFeB Magnets waxaa si ballaaran loo isticmaalaa caaryada fudud iyo guryaha magnetic sare, heerkulka shaqada deggan, daxalka-iska caabin wanaagsan. Waxay suurtogal u tahay inay geliyaan caaryada qaybo kale.
Isku darka dhamaystiran ee habka duritaanka iyo hantida sare ee naadir-dhulku waxay suurtogal ka dhigaysaa in la sameeyo magnet Ndfeb giraanta si fudud ugu xidhan oo loogu talagalay afhayeenka. Magnets Neodymium Bonded ayaa faa'iido u leh qaabab aad u horumarsan marka loo eego Magnets-ka Sintered. Magnet-ku wuxuu u baahan yahay in lagu dahaadho lakabka epoxy madow ama cawlan ama Parylene si looga ilaaliyo daxalka.
Magnet NdFeB Hot-pressed oo loo qaybiyay laba nooc, Hot pressed isotropic NdFeB (MQ 2) iyo hot-pressed anisotropic NdFeb magnet (MQ 3) . Magnet-ka NdFeB anisotropic-kuleyl la cadaadiyo inta badan waa anisotropic radially-oriented giraanta magnet kaas oo lagu soo saaro cadaadis iyo qallafsanaan iyadoo si degdeg ah loo demiyo budada magnetka ee NdFeB heerkul sarreeya
Magnets-ka-xidhan ee neodymium-iron-boron (NdFeB) waa magnets xooggan oo loo isticmaalo codsiyo kala duwan. Dahaarka Epoxy ayaa inta badan loo isticmaalaa magnets NdFeB. Dajinta nikkel-ka aan koronto lahayn ayaa sidoo kale loo isticmaalaa si looga hortago daxalka. Maaddada NdFeB ee ku xidhan Isotropic waxaa lagu magnetized karaa jiha kasta, ama leh tirar badan.
Maaddada Nd-Fe-B ee ku xidhan waa isotropic, sidaa darteed waxaa lagu dhejin karaa jiho kasta, oo ay ku jiraan qabanqaabada kala duwanaanshaha. Sababtoo ah maaddadu waxay ku jirtaa xargaha epoxy, waxaa lagu farsameyn karaa mishiinka ama saxarada. Si kastaba ha ahaatee, maaddadu ma taageeri doonto dunta, markaa godadka lama taaban karo. Maaddada Nd-Fe-B ee ku xidhan waxa inta badan loo adeegsadaa in si weyn loo dhimo cabbirka nashqadaha isticmaalay walxaha magnet-ka dhoobada ah. Dhimista cabbirka weyn ayaa la gaari karaa sababtoo ah maaddadu waxay ku dhowdahay saddex jeer ka xoog badan walxaha magnet dhoobada. Intaa waxaa dheer, maadaama maaddadu ay tahay isotropic, waxay noqon kartaa magnetized multi-polar, sida qaabka NSNS ee dhexroorka dibadda ee giraanta.
Magnets NdFeB Bonded waxay leeyihiin remanence sare, jujuub sare, wax soo saarka tamarta sare, waxqabadka sare iyo saamiga qiimaha, fududahay in la farsameeyo cabbirro kala duwan, iyo faa'iidada ugu yar ee qeexitaanka.Waxay noqon karaan unit medina oo ay weheliyaan qaybaha kale, si ballaaran loo isticmaalo muddo gaaban, yar yar. , iftiin, iyo alaab elegtaroonig ah oo khafiif ah.
Magnets NdFeb ee xidhan ayaa ka xoog badan birlabeedka la isku duro, waxa kale oo ay faa'iido u leeyihiin qaabab aad u horumarsan marka loo eego magnets-ka sintered. Qasab sare, wax soo saarka tamarta sare, iska caabinta daxalka, iyo iska caabinta heerkulka.
Budada neodymium ee xidhan ayaa loo isticmaalaa si loo abuuro magnets-kan. Budada waa la dhalaaliyaa oo lagu qasaa polymer. Qaybaha ayaa markaa la riixaa ama la saaraa si loo abuuro alaabta. Magnet-ka Neodymium ee xidhan waxa lagu dhejin karaa qaabab adag oo leh tiirar badan. In kasta oo aad uga daciifsan magnets-ka Sintered Neodymium, magnet-yada neodymium-ka ee xidhan waxa ay siinayaa dabacsanaan weyn marka loo eego qaababka la samayn karo. Waxay kaloo ka fudud yihiin Samarium Cobalt, waxayna leeyihiin heerkul hoose oo la aqbali karo (qasab). Si kastaba ha ahaatee, waxay bixiyaan qiimo aad u fiican codsiyada u baahan magnet yar ama isticmaalaya giraangiraha radial.
Codsiga:
Qalabka Automation-ka ee Xafiiska, Mashiinnada Korontada, Qalabka Maqalka-muuqaalka ah, Qalabka, Matoorada yar-yar iyo Mashiinnada cabbiraadda, Taleefannada gacanta, CD-ROM-ka, Matoorada DVD-ROM-ka, Matoorada Spindle-ka Hard Disk-ga HDD, Matoorada kale ee micro DC, iyo Aautomation-ka iwm.
Heerkulka Shaqada ee ugu badan:
Inkasta oo heerkulka Curie ee maaddada NdFeB ay ku dhowdahay 310 ºC 0% walxo kobalt ah oo ka weyn 370 ºC ee 5% kobalt, qaar ka mid ah luminta wax soo saarka ayaa laga yaabaa in la filayo xitaa heerkul dhexdhexaad ah. Magnets Neo sidoo kale waxay leeyihiin iskudhaf heerkul dib loo celin karo dhexdhexaad ah kaas oo yaraynaya wadarta guud ee wax soo saarka magnetic marka heerkulku kor u kaco. Xulashada magnets neo halkii SmCo, waa shaqo heerkulka ugu badan ee codsiga, loo baahan yahay wax soo saarka magnetic heerkulka shaqada caadiga ah iyo wadarta kharashka nidaamka.
Neo magnets sidoo kale waxay leeyihiin xoogaa xaddidaad ah sababtoo ah dabeecadooda daxalka ah. Marka ay xaaladdu qoyan tahay, dahaar ilaalin ah ayaa aad loogu talinayaa. Dahaarka si guul leh loo mariyey waxaa ka mid ah; dahaarka elektarooniga ah, dahaarka budada ah, dhejinta nikkel, dhejinta zinc, parylene iyo isku darka daahan.
