Iimagnethi ze-Bonded Neodymium zenziwe ngezinto ezinamandla ze-Nd-Fe-B ezixutywe kwisibophelelo se-epoxy. Umxube umalunga ne-97 vol% ye-magnetic material ukuya kwi-3 vol% epoxy. Inkqubo yokuvelisa ibandakanya ukudibanisa i-Nd-Fe-B powder kunye ne-epoxy binder kunye nokuxinzelela umxube kwi-press kunye nokuphilisa inxalenye kwi-oven. Ekubeni izinto zenziwe nge-compression bonding, imilinganiselo ngokuqhelekileyo iyahluka .002 "okanye ingcono kwi-run enikiweyo.I-Bonded Compression Molded NdFeB Magnets isetyenziswa ngokubanzi kwi-mold elula kunye neempawu eziphezulu zemagneti, ubushushu bokusebenza obuzinzile, ukuxhathisa okuhle kwe-corrosion. Ziyakwazi ukufaka isikhunta kunye namanye amalungu.
Udibaniso olupheleleyo lwenkqubo yokutofa kunye nempahla ephezulu enqabileyo-yomhlaba engumgubo yenza kube nokwenzeka ukwenza i-bonding eyomeleleyo ye-Ndfeb ring magnet yesithethi. I-Bonded Neodymium Magnets ine-advanteji yeemilo eziphambili ngakumbi xa kuthelekiswa ne-Sintered Magnets. Umazibuthe kufuneka uqatywe umaleko we-epoxy emnyama okanye engwevu okanye iParylene ukuyikhusela kumhlwa.
Imagnethi ye-NdFeB ecinezelwe ngokushushu yahlulahlulwe yaba ziindidi ezimbini, i-Hot pressed isotropic NdFeB (MQ 2) kunye ne-hot-extruded anisotropic NdFeb magnet (MQ 3) .I-Hot-pressed isotropic NdFeb umazibuthe iveliswa ngokukhawuleza kwacinywa i-NdFeB magnetic pw der phantsi kobushushu obuphezulu. ngokucinezelwa.I-anisotropic ye-anisotropic ye-NdFeB umazibuthe ecinezelekileyo ngokuyintloko i-anisotropic radially-oriented ring magnetic eveliswa ngoxinzelelo kunye ne-extrusion deformation ngokucinywa ngokukhawuleza kwe-NdFeB ngumgubo wemagnethi phantsi kobushushu obuphezulu.
Iimagnethi ze-neodymium-iron-boron (NdFeB) ziimagnethi ezinamandla ezisetyenziselwa izicelo ezahlukeneyo. I-epoxy coating ixhaphake kakhulu esetyenziselwa iimagnethi zeNdFeB ezibotshiwe; i-electroless nickel plating ikwasetyenziselwa ukuthintela ukubola. Izinto ze-Isotropic ezibotshelelwe kwi-NdFeB zinokuthi zenziwe ngemagneti kulo naliphi na icala, okanye ngeepali ezininzi.
I-Bonded Nd-Fe-B imathiriyeli isotropic, ngoko inokuthi ifakwe imagneti kulo naliphi na icala, kubandakanywa namalungiselelo amaninzi. Ngenxa yokuba izinto zikwi-epoxy binder, zinokutshintshwa kumatshini wokusila okanye kwilathe. Nangona kunjalo, izinto eziphathekayo aziyi kuxhasa intambo, ngoko ke imingxuma ayinakuthatyathwa. I-Bonded Nd-Fe-B imathiriyeli ihlala isetyenziselwa ukunciphisa kakhulu ubungakanani boyilo olusebenzise imathiriyeli yemagnethi yeceramic. Ukuncitshiswa kobungakanani okubalulekileyo kunokufezekiswa ngenxa yokuba imathiriyeli yomelele ngokuphindwe kathathu kunesixhobo semagnethi ye-ceramic. Ukongezelela, ekubeni izinto eziphathekayo ziyi-isotropic, zinokuthi zenziwe ngemagnethi ezininzi zepolar, njengepateni ye-NSNS kububanzi obungaphandle bendandatho.
Iimagnethi ze-Bonded NdFeB zineremanence ephezulu, ukunyanzeliswa okuphezulu, imveliso yamandla aphezulu, ukusebenza okuphezulu kunye nomlinganiselo wexabiso, kulula ukusetyenzwa ngobungakanani obahlukeneyo, kunye nobuncinci benkcazo inzuzo.Inokuba yeyunithi ye-medina kunye namanye amacandelo, asetyenziswa ngokubanzi kwixesha elifutshane, elincinci. , ukukhanya, kunye neemveliso ze-elektroniki ezincinci.
Iimagnethi ezibotshelelweyo zeNdFeb zinamandla amakhulu wemagnethi kunemagnethi abunjiweyo, zikwanelungelo leemilo ezihambele phambili ngakumbi xa kuthelekiswa noomazibuthe. Ukunyanzeliswa okuphezulu, imveliso yamandla aphezulu, ukumelana nokugqwala, kunye nokumelana nobushushu.
I-Bonded neodymium powder isetyenziselwa ukwenza ezi magnethi. Umgubo uyancibilika kwaye uxutywe ngepolymer. Amacandelo ke acinezelwe okanye akhutshelwe ukwenza imveliso. Imagnethi ye-Bonded Neodymium inokutsalwa ngokweepateni ezintsonkothileyo ezineepali ezininzi. Nangona zibuthathaka kakhulu kunemagnethi ye-Sintered Neodymium, iimagnethi ze-Bonded neodymium zinika ukuguquguquka okukhulu ngokwemilo enokwenziwa. Kananjalo zikhaphukhaphu kuneSamarium Cobalt, kwaye zineqondo lobushushu elamkelekileyo elisezantsi (ukunyanzeliswa). Nangona kunjalo, banikezela ngexabiso elibalaseleyo kwizicelo ezifuna umazibuthe omncinci okanye zisebenzisa iiringi zeradial.
Isicelo:
Izixhobo zokuziSebenzisa ze-Ofisi, oomatshini boMbane, izixhobo ezivakalayo ezibonwayo, izixhobo, iimotor ezincinci kunye noomatshini bokulinganisa, iiselfowuni, i-CD-ROM, ii-DVD-ROM drive motors, ii-hard disk spindle motors HDD, ezinye ii-micro DC motors, kunye nezixhobo ezizenzekelayo njl.
Obona bushushu bokusebenza:
Nangona ubushushu beCurie kwisixhobo se-NdFeB bumalunga ne-310 ºC kwi-0% yemathiriyeli ye-cobalt ukuya ngaphezulu kwe-370 ºC ye-5% ye-cobalt, enye ilahleko engenakubuyiseka yemveliso inokulindeleka kumaqondo obushushu aphakathi. Imagnethi zeNeo zikwanayo neqondo eliphezulu eliBuyiselwayo loBugcisa lweNgcaciso enciphisa isiphumo semagnethi xa ubushushu bunyuka. Ukukhethwa kwemagnethi ye-neo endaweni ye-SmCo, ngumsebenzi wobushushu obukhulu besicelo, imveliso yemagnethi efunekayo kubushushu obuqhelekileyo bokusebenza kunye neendleko zizonke zenkqubo.
Iimagnethi zeNeo nazo zinemida ethile ngenxa yendlela eziziphatha ngayo kumhlwa. Kwimeko efumileyo, kucetyiswa kakhulu ukugquma okanye ukugquma okukhuselweyo. Iingubo eziye zasetyenziswa ngempumelelo ziquka; i-e-coating, i-powder coating, i-nickel plating, i-zinc plating, i-parylene kunye nendibaniselwano yezi tyalo.
