Imagnethi zeNeodymium zezona magnethi zibalaseleyo ezingajikwayo ezithengiswayo, naphi na emhlabeni.Ukuchasana nokukhutshwa kweemagneti xa kuthelekiswa nemagnethi ye-ferrite, alnico kunye nesamarium-cobalt.
✧ Iimagnethi zeNeodymium VS iimagnethi zeferrite eziqhelekileyo
Iimagnethi zeFerrite ziimagnethi zezinto ezingezizo ezentsimbi ezisekwe kwi-triiron tetroxide (umlinganiselo omiselweyo wobunzima bentsimbi ukuya kwi-ferrous oxide).Eyona nto ingalunganga kwezi magnethi kukuba azinakwenziwa ngokuthanda kwazo.
Imagnethi ye-Neodymium ayinawo amandla abalaseleyo emagnethi kuphela, kodwa ikwaneempawu ezilungileyo zoomatshini ngenxa yokudityaniswa kwesinyithi, kwaye zinokulungiswa ngokulula zibe ziimo ezahlukeneyo ukuze zilungele iimfuno ezininzi ezahlukeneyo.Ukungalungi kukuba i-metal monomers kwimagnethi ye-neodymium kulula ukugqwala kunye nokuwohloka, ngoko ke umphezulu uhlala ugcwele i-nickel, i-chromium, i-zinc, i-tin, njl.
✧ Ukuqulunqwa kwemagnethi ye-neodymium
Iimagnethi zeNeodymium zenziwe nge-neodymium, intsimbi kunye ne-boron zidityaniswe kunye, zihlala zibhalwa njenge-Nd2Fe14B.Ngenxa yokwakheka okuzinzileyo kunye nokukwazi ukwenza iikristale ze-tetragonal, imagnethi ye-neodymium inokuqwalaselwa ngokucokisekileyo ukusuka kwindawo yokujonga iikhemikhali.Ngo-1982, uMakoto Sagawa we-Sumitomo Special Metals wavelisa imagnethi ye-neodymium okokuqala.Ukusukela ngoko, iimagnethi zeNd-Fe-B ziye zacinywa ngokuthe ngcembe kwiimagnethi zeferrite.
✧ Zenziwa njani iimagnethi zeneodymium?
INYATHELO 1-Kuqala kuzo zonke izinto, zonke izinto zokwenza umgangatho okhethiweyo wemagnethi zibekwe kwisithando somlilo sokucoca ivacuum, sifudunyezwe kwaye sinyibilikisiwe ukuphuhlisa imveliso yealloy.Lo mxube uye upholiswe phantsi ukuze kuphuhliswe ii-ingots phambi kokuba zicolwe kanye kwiinkozo ezincinci kwi-jet Mill.
INYATHELO 2- I powder-fine super-fine ke icinezelwe kwi-mold kunye kwaye ngexesha elifanayo amandla amagnetic asetyenziswa kwi-mold.I-Magnetism ivela kwikhoyili yentambo esebenza njengemagnethi xa kudlula umsinga wombane kuyo.Xa isakhelo sesuntswana umazibuthe sihambelana nemiyalelo yemagnethi, oku kubizwa ngokuba yimagnethi yeanisotropic.
INYATHELO 3-Esi ayisosiphelo senkqubo, endaweni yoko, ngalo mzuzu izinto ezifakwe nguzibuthe zikhutshiwe kwaye ngokuqinisekileyo ziya kwenziwa zimagneti kamva ngelixa usenza njalo.Inyathelo elilandelayo lelokuba imathiriyeli ifudunyezwe, kude kube kwindawo yokunyibilika kwindlela ebizwa Eli nyathelo lilandelayo lelokuba imveliso ifudunyezwe, phantse ide ibe yindawo yokunyibilika kwindlela ebizwa ngokuba yi-sintering eyenza ukuba amasuntswana umazibuthe omgubo adibane.Le nkqubo yenzeka kwindawo engena-oxygen, i-inert setting.
INYATHELO 4- Ngokucacileyo apho, izinto ezifudunyeziweyo zipholiswa ngokukhawuleza kusetyenziswa indlela eyaziwa ngokuba kukucima.Le nkqubo yokupholisa ngokukhawuleza inciphisa iindawo zemagnetism embi kwaye yonyusa ukusebenza.
INYATHELO 5-Ngenxa yokuba iimagnethi ze-neodymium zinzima kakhulu, zibenza babe sesichengeni sokonakalisa kunye nokonakalisa, kufuneka zigqunywe, zicocwe, zomiswe, kwaye zifakwe ipleyiti.Zininzi iintlobo ezahlukeneyo zokugqitywa ezenziweyo kunye neemagnethi ze-neodymium, enye yezona zinto ziqhelekileyo ngumxube we-nickel-copper-nickel kodwa zinokuqatywa kwezinye iintsimbi kunye nerabha okanye i-PTFE.
INYATHELO6- Ngokukhawuleza xa iplatiwe, imveliso egqityiweyo iphinda ifakwe kwi-coil, ethi, xa umbane wombane uhamba ngayo uvelise intsimi yamagnetic ngokuphindwe kathathu kunobunzima obufunekayo bemagnethi.Le yinkqubo esebenzayo kangangokuba ukuba umazibuthe akagcinwanga kwindawo inokuphoswa ukusuka kwikhoyili-njengembumbulu.
I-AH MAGNET yi-IATF16949, ISO9001, ISO14001 kunye ne-ISO45001 umenzi ovunyiweyo wazo zonke iintlobo zemagnethi ye-neodymium yokusebenza ephezulu kunye neendibano zemagnethi ezineminyaka engama-30 yamava endle.Ukuba unomdla kwimagnethi ye-neodymium, nceda uzive ukhululekile ukuqhagamshelana nathi!
