Omaginethi be-Neodymium bangamaginethi angcono kakhulu angenakuguqulwa athengiswayo, noma kuphi emhlabeni, ukumelana ne-demagnetization uma kuqhathaniswa namaginethi e-ferrite, i-alnico ngisho ne-samarium-cobalt.
✧ Omaginethi be-Neodymium VS omaginethi be-ferrite abavamile
Ama-magnet e-Ferrite angama-magnet angewona awensimbi asekelwe ku-triiron tetroxide (isilinganiso esilinganiselwe sesisindo se-iron oxide ne-ferrous oxide). Inkinga enkulu yala ma-magnet ukuthi awakwazi ukwenziwa ngokuthanda kwawo.
Omaginethi be-Neodymium abagcini nje ngokuba namandla amahle kakhulu kazibuthe, kodwa futhi banezakhiwo ezinhle zemishini ngenxa yokuhlangana kwezinsimbi, futhi bangacutshungulwa kalula babe yizimo ezahlukahlukene ukuze bavumelane nezidingo eziningi ezahlukene. Okubi ukuthi ama-monomer ensimbi kumaginethi e-neodymium kulula ukuwagqwala futhi awohloke, ngakho-ke ubuso buvame ukumbozwa nge-nickel, i-chromium, i-zinc, i-tin, njll. ukuvimbela ukugqwala.
✧ Ukwakheka kwemagnethi ye-neodymium
Amamagnethi e-Neodymium enziwe nge-neodymium, insimbi kanye ne-boron ehlanganiswe ndawonye, evame ukubhalwa njenge-Nd2Fe14B. Ngenxa yokwakheka okuzinzile kanye nekhono lokwenza amakristalu e-tetragonal, amamagnethi e-neodymium angabhekwa njengombono wamakhemikhali kuphela. 1982, uMakoto Sagawa we-Sumitomo Special Metals wakha amamagnethi e-neodymium okokuqala. Kusukela ngaleso sikhathi, amamagnethi e-Nd-Fe-B asuswe kancane kancane kumamagnethi e-ferrite.
✧ Amagnethi e-neodymium enziwa kanjani?
ISINYATHELO 1- Okokuqala, zonke izinto zokwenza ikhwalithi ekhethiwe yemagnethi zifakwa esithandweni sokuhlanza i-vacuum cleaner, zifudumale futhi zincibilikiswe ukuze kukhiqizwe umkhiqizo we-alloy. Le ngxube ibe isipholiswa ukuze kukhiqizwe ama-ingot ngaphambi kokuba igaywe ibe yizinhlamvu ezincane emshinini wokugaya ijethi.
ISINYATHELO 2- Impuphu ecolekile kakhulu icindezelwa ku-mold kanye ngesikhathi esifanayo amandla kazibuthe asetshenziswa ku-mold. I-Magnetism ivela ku-coil yekhebula esebenza njenge-magnet lapho kudlula ugesi kuyo. Lapho uhlaka lwezinhlayiya ze-magnet luhambisana nemiyalelo ye-magnetism, lokhu kubizwa ngokuthi i-anisotropic magnet.
ISINYATHELO 3- Lokhu akupheleli kule nqubo, kunalokho, okwamanje izinto ezisebenzisa ugesi azinawo ugesi futhi ngokuqinisekile zizosebenzisa ugesi kamuva ngenkathi kwenziwa kanjalo. Isinyathelo esilandelayo ukuthi izinto zifudumale, cishe kuze kube yilapho kuncibilika enkambisweni ebizwa ngokuthi Isenzo esilandelayo ukuthi umkhiqizo ufudumale, cishe kuze kube yilapho kuncibilika enkambisweni ebizwa ngokuthi i-sintering eyenza ama-magnet bits anombala ahlanganiswe ndawonye. Le nqubo yenzeka endaweni engenawo umoya-mpilo, engenawo ugesi.
ISINYATHELO 4- Cishe lapho, izinto ezifudumalayo ziphola ngokushesha kusetshenziswa indlela eyaziwa ngokuthi ukucima. Le nqubo yokupholisa ngokushesha inciphisa izindawo ezinobungozi obungamandla kagesi futhi ikhulisa nokusebenza kahle.
ISINYATHELO 5- Ngenxa yokuthi omaginethi be-neodymium baqinile kakhulu, okwenza basengozini yokulimaza nokulimaza, kufanele bagqunywe, bahlanzwe, bomiswe, futhi bafakwe ipulasitiki. Kunezinhlobo eziningi zokuqeda ezisetshenziswa omaginethi be-neodymium, enye evame kakhulu ukuba yingxube ye-nickel-copper-nickel kodwa ingagqunywa ngezinye izinsimbi kanye nerabha noma i-PTFE.
ISINYATHELO 6- Uma nje usufakwe ipulasitiki, umkhiqizo oqediwe uphinde ufakwe i-magnetization ngokuwufaka ngaphakathi kwe-coil, okuthi, uma ugesi udlula kuyo ukhiqize amandla kazibuthe anamandla aphindwe kathathu kunokuqina okudingekayo kwe-magnet. Lena inqubo ephumelelayo kangangokuthi uma i-magnet ingagcinwa endaweni yayo ingaphonswa kusuka ku-coil njengenhlamvu.
I-AH MAGNET ingumkhiqizi ogunyaziwe we-IATF16949, ISO9001, ISO14001 kanye ne-ISO45001 wazo zonke izinhlobo zama-magnets e-neodymium asebenza kahle kanye nama-magnetic assemblies aneminyaka engaphezu kwengu-30 yesipiliyoni kulo mkhakha. Uma unesithakazelo kuma-magnets e-neodymium, sicela ukhululeke ukuxhumana nathi!
