Saamaynta budada wax lagu daro ee habka wax soo saarka ee NdFeb maran.
Si loo soo saaro NdFeb wax qabad heersare ah oo sinteredmagnet joogto ahwax, waa in aan si loo xakameeyo xajmiga socodka hawada shiidi qaybaha budada magnetic, si size ee qayb ka budada magnetic in 2.5 ~ 5μm xisaabiyey in ka badan 95%.Xinfeng Magnet waxay ogaatay in habka si weyn loo wanaajin karo iyadoo lagu darayo wax ka beddelka budada gaarka ah ee habka socodka hawada.
Waxyaabaha lagu daro budada wax laga beddelay waa inay lahaadaan shaqo isku dhafan, kuwaas oo ah: (1) shaqada anti-oxidation;(2) Hagaajinta shaqada dheecaanka budada;(3) Kahortagga gubashada budada, oo ah shaqada dib u dhigista bararka.Qadarka wax lagu daro waxay ku saabsan tahay 0.035% ~ 0.05% (jajab tiro badan) ee budada magnetic, taas oo inta badan lagu daro isla mar ahaantaana budada magnetic ee goobta quudinta qulqulka hawada.
Wax-qabadku waa unugyo dabiici ah oo ka kooban qaybo badan, oo leh kooxo lipophilic ah, kuwaas oo ah silsiladaha hydrocarbon, oo ay ku jiraan kooxo yaryar oo polar ah, sida kooxaha dufanka leh, si silsiladda hydrocarbon u yeelato dherer silsilad ku habboon.Qaybaha budada magnetic waxay si isdaba joog ah isku dhacaan oo taabtaan waxyaabo lagu daro habka socodka hawada, si dusha sare ee qayb kasta lagu dahaadhay lakabka filim wax lagu daro leh oo dhumucdiisu tahay 5 ~ 8nm.Waxay ka ciyaartaa doorarka soo socda: (1) Ka ilaali walxaha budada ah inay la xiriiraan hawada, waxay ciyaaraan doorka anti-oxidation;(2) Daciif saamaynta magnetostatic ee u dhexeeya qaybaha budada, yaraynta agglomeration u dhexeeya qaybaha budada, ciyaara doorka kala-firdhinta;(3) Kordhi dareeraha iyo dhaqdhaqaaqa qaybaha budada waxayna ciyaaraan doorka saliidda;(4) Waxay faa'iido u leedahay jihada qaybaha budada ah ee goobta magnetic, taas oo hagaajin karta jihada;BR waxaa lagu kordhin karaa 0.02-0.04 T, iyo badeecada tamarta magnetic (BH) m waa la kordhin karaa si u dhiganta.Waa in la ogaadaa in heerkulka isbeddelka ah ee wax lagu daro uu yahay 350 ℃.Heerkulka qulqulaya wuxuu u baahan yahay in lagu hayo 400-420 ℃ in muddo ah, si waxyaabaha lagu daro laga saaro magnetka, si aan loo carbin.
Shuruudaha lagama maarmaanka u ah soo saarista magnet joogto ah ee NdFeb tayo sare leh.
Si loo helo hanuunin wanaagsan ee magnets, Xinfeng magnet ayaa soo gebagebowday sannado badan oo tijaabo ah iyo jawaab celin isku dhafan oo ku saabsan isticmaalka macaamiisha suuqa in ay lagama maarmaan tahay in la sameeyo budada magnetic NdFeb sintered si loo buuxiyo shuruudaha soo socda si alaabooyinka tayada sare leh ay awoodaan. la abuuro, oo kaliya agabka dawada ayaa wanaagsan, daawaduna way fiicnaan doontaa.(1) Cabbirka walxaha budada ah waa yar yahay (3 ~ 4μm), iyo qaybinta cabbirku waa cidhiidhi, taas oo ah, shuruudaha 3 ~ 4μm qaybo ka mid ah 95%, ma laha wax ka yar 1μm ama in ka badan qaybaha 7μm, Hubi in dhammaan qaybaha ay yihiin hal crystal.(2) Qaybaha budada ayaa ah kuwo wareegsan ama qiyaas ahaan wareegsan.(3) Cilladaha kristaalka ah ee walxaha budada ah waa inay ahaadaan kuwa ugu yar intii suurtagal ah.(4) Marka la burburinayo, waxaa fiican in la jebiyo weheliyaan marxaladda crystal, iyo ku dadaalaan si ay u gaaraan dusha sare ee qayb kasta ayaa Rich Nd wajiga, kaas oo dhigaya aasaaska wejiga dareere sintering ka dambeeya oo ka hortagtaa dhacdo fasalka ⅱ xadka hadhuudh.(5) Wasakhda iyo gaasaska lagu dhejiyay dusha sare ee walxaha budada ah waa inay ahaadaan kuwa ugu yar ee suurtogalka ah, gaar ahaan waxa ku jira ogsijiinta waa inay yaraataa.Sidaa darteed, habka diyaarinta budada waa in lagu fuliyaa si nadiif ah oo nadiif ah oo gaaska aan firfircoonayn ama xaaladaha vacuum, si looga hortago taabashada budada magnetic ee oksijiinta ama hawada qoyan.Shanta shuruudood ee kor ku xusan ayaa lagama maarmaan u ah soo saarista tayada sare ee sintered NdFeb magnets joogto ah, la'aanta mid kastaa ma aha mid la jecel yahay, waxay u egtahay mid fudud, dhab ahaantii mid kastaa wuxuu samayn karaa kaamil ma fududa, Xinfeng magnets wuxuu diyaar u yahay inuu si wada jir ah ula shaqeeyo dadka dhammaan qaybaha kala duwan ee nolosha. samee alaabo kaamil ah, kuna dadaal inaad siiso macaamiisha adeegyo tayo badan leh.
Horumarka cusub ee Xinfeng Magnet ee horumarinta isku-xidhka magnet-ka NdFeb.
Qasabku waa mid ka mid ah halbeegyada farsamo ee muhiimka ah ee magnet joogto ah.Kordhinta qasbiddu waxay kordhin kartaa wax soo saarka tamarta magnetic weyn ee magnetka, hagaajinta iska caabinta demagnetization ee magnetka joogtada ah ee la isticmaalo, waxayna wanaajisaa xasilloonideeda.Waqtigan xaadirka ah, diyaarinta saafiga ah ternary ternary sintered NdFeb magnet joogto ah, sifooyinka magnetic farsamada iyo qiyamka aragtida, iyo remanence BR ayaa mar hore gaadhay 96.27% ee qiimaha aragti, iyo wax soo saarka tamarta magnetic weyn ee BH ayaa gaadhay 91.5% ka mid ah aragtideeda. qiimaha.Si kastaba ha ahaatee, xoogga qasabku waxa uu gaadhay kaliya 12% qiimaheeda aragtiyeed.Waa awood weyn oo lagu hagaajinayo xooggeeda qasabka ah, weli waxaa jira koror weyn oo meel bannaan ah.Xinfeng magnet ayaa si adag uga shaqaynaysay arrintan.
Marka hore, qasbidda magnetka si wax ku ool ah ayaa loo wanaajin karaa iyadoo lagu beddelo Nd qayb ahaan Dy iyo Tb.Si kastaba ha ahaatee, khayraadka birta ah ee dhifka ah ee dhulka, Dy iyo Tb waxay ku yar yihiin maaddooyinka qaaliga ah, Dy iyo Tb-na waxa lagu dari karaa oo kaliya tirooyin.Marka labaad, marka lagu daro qaar ka mid ah walxaha birta ah sida AL, Nb, Ga, Ti, Zr, Mo, iwm., marka walxahaas ay galaan crystal, qaab-dhismeedka yar-yar iyo waxqabadka habka ayaa si cad u wanaajinaya, oo kordhiya qasbidda magnetka.Seddexaad, qasbidda birlabeedka si wax ku ool ah ayaa loo wanaajin karaa iyadoo lagu darayo curiyeyaasha lana isticmaalo heerkul hooseeya ama habka daawaha labanlaabka ah si loo yareeyo celceliska cabbirka crystal.
Marka xigta, Xinfeng magnet wuxuu sii wadi doonaa inuu si adag u shaqeeyo si loo hagaajiyo wax soo saarka tamarta magnetic weyn ee NdFeb sintered, oo si joogto ah u siisa alaabada ka wanaagsan macaamiisha.
