Ozibuthe be-Neodymium bangozibuthe abahamba phambili abangahlehlekisiwe abathengiswayo, noma kuphi emhlabeni. ukumelana ne-demagnetization uma kuqhathaniswa nozibuthe be-ferrite, i-alnico kanye ne-samarium-cobalt.
✧ Ozibuthe be-Neodymium VS omazibuthe be-ferrite abavamile
Ozibuthe beFerrite bangozibuthe bezinto ezingezona ezensimbi ezisekelwe ku-triiron tetroxide (isilinganiso esilinganiselwe sesisindo se-iron oxide kuya ku-ferrous oxide). Ububi obukhulu balezi zidonsa ukuthi azikwazi ukufojwa ngokuthanda kwazo.
Ozibuthe be-Neodymium abagcini nje ngokuba namandla kazibuthe amahle kakhulu, kodwa futhi banezakhiwo ezinhle zemishini ngenxa yokuhlangana kwezinsimbi, futhi bangacutshungulwa kalula babe yizimo ezihlukahlukene ukuze bavumelane nezidingo eziningi ezahlukene. Okubi ukuthi ama-metal monomers kumamagnet we-neodymium kulula ukugqwala futhi awonakalise, ngakho-ke indawo engaphezulu nayo ivame ukumbozwa nge-nickel, i-chromium, i-zinc, ithini, njll. ukuvimbela ukugqwala.
✧ Ukwakheka kazibuthe neodymium
Ozibuthe be-Neodymium benziwe nge-neodymium, insimbi ne-boron kuhlanganiswe ndawonye, ngokuvamile kubhalwe ngokuthi Nd2Fe14B. Ngenxa yokwakheka okungaguquki kanye nekhono lokwenza amakristalu e-tetragonal, izibuthe ze-neodymium zingabhekwa njengendawo yokubuka yamakhemikhali. Ngo-1982, uMakoto Sagawa we-Sumitomo Special Metals wakha omazibuthe be-neodymium okokuqala ngqa. Kusukela lapho, omazibuthe be-Nd-Fe-B baye basuswa kancane kancane kumagnethi we-ferrite.
✧ Benziwa kanjani omazibuthe be-neodymium?
ISINYATHELO 1- Okokuqala nje, zonke izakhi zokwenza ikhwalithi kazibuthe ekhethiwe zifakwa esithandweni sokungeniswa sokuhlanza ivacuum, sishisiswe futhi sincibilikiswe ukuthuthukisa umkhiqizo we-alloy. Le ngxube ibe isipholiswa phansi ukuze ithuthukise ama-ingots ngaphambi kokuba igaywe ibe yizinhlamvu ezincane emshinini wokugaya.
ISINYATHELO 2- I-super-fine powder ibe isicindezelwa esikhunjeni futhi ngesikhathi esifanayo amandla kazibuthe asetshenziswa esikhunjeni. I-Magnetism ivela kukhoyili yekhebula esebenza njengozibuthe lapho intambo kagesi idlula kuyo. Lapho uhlaka lwezinhlayiyana zikazibuthe lufana neziyalezo zikazibuthe, lokhu kubizwa ngokuthi uzibuthe we-anisotropic.
ISINYATHELO 3- Lokhu akusona isiphetho senqubo, esikhundleni salokho, kulo mzuzu izinto ezidonsa uzibuthe zikhishwe uzibuthe futhi zizokhishwa uzibuthe ngokuhamba kwesikhathi ngenkathi zenza kanjalo. Isinyathelo esilandelayo esokuba impahla ishiselwe, kuze kufike iphuzu lokuncibilika ngendlela ebizwa Isenzo esilandelayo esokuba umkhiqizo ushiselwe, cishe uze uncibilike ngendlela ebizwa nge-sintering eyenza izingcezu zikazibuthe eziyimpuphu zihlangane. Le nqubo yenzeka endaweni engenawo umoya-mpilo, nesilungiselelo esingasebenzi.
ISINYATHELO 4- Cishe lapho, izinto ezishisiwe zipholiswa ngokushesha kusetshenziswa indlela eyaziwa ngokuthi ukucisha. Le nqubo yokupholisa ngokushesha inciphisa izindawo ze-magnetism embi futhi iphinde ikhulise ukusebenza.
ISINYATHELO 5- Ngenxa yokuthi omagnethi be-neodymium baqine kakhulu, okwenza kube lula ukulimaza nokulimaza, kufanele bagcotshwe, bahlanzwe, bomiswe, futhi bahlanganiswe. Kunezinhlobo eziningi ezahlukene zokuqedela ezisetshenziswa ngozibuthe be-neodymium, enye yezinto ezijwayeleke kakhulu ukuba yingxube yenikeli yethusi-nickel kodwa ingagcotshwa kwezinye izinsimbi kanye nerabha noma i-PTFE.
ISINYATHELO6- Ngokushesha nje lapho upuletiwe, umkhiqizo oqediwe uphinde ufakwe uzibuthe ngokuwufaka ngaphakathi kwekhoyili, okuthi, lapho ugesi uhanjwa kuwo ukhiqize amandla kazibuthe aphindwe kathathu ngaphezu kokuqina okudingekayo kukazibuthe. Lena inqubo esebenza ngempumelelo kangangokuthi uma uzibuthe engagcinwa endaweni angaphonswa ekhoyili njengenhlamvu.
I-AH MAGNET ingumkhiqizi ogunyaziwe we-IATF16949, ISO9001, ISO14001 kanye ne-ISO45001 wazo zonke izinhlobo zozibuthe ze-neodymium ezisebenza kahle kanye nama-magnetic assemblies aneminyaka engaphezu kwengama-30 yesipiliyoni kulo mkhakha. Uma unentshisekelo kuzibuthe ze-neodymium, sicela ukhululeke ukuxhumana nathi!
