Neodymium magnetik bụ ihe ndọta kachasị mma na-enweghị ike ịtụgharị azụ ahịa, ebe ọ bụla n'ụwa.iguzogide demagnetisation mgbe ọ dị iche na ferrite, alnico na ọbụna samarium-cobalt magnet.
✧ Neodymium magnetik VS ihe ndọta ferrite
Ihe ndọta ferrite bụ ihe ndọta na-abụghị ọla dabere na triiron tetroxide (nhazi oke nke ígwè oxide na ferrous oxide).Ihe ọghọm dị na magnetik ndị a bụ na a pụghị imepụta ha ma ọ dị ha mma.
Neodymium magnetik ọ bụghị naanị na ọ nwere ezigbo ike ndọta, kamakwa ọ nwere ezigbo ihe eji arụ ọrụ n'ihi ngwakọta nke ọla, enwere ike ịhazi ya ngwa ngwa ka ọ bụrụ ụdị dị iche iche iji gboo mkpa dị iche iche.Mwepu bụ na metal monomers na neodymium magnets dị mfe nchara na njọ, ya mere a na-ejikarị nickel, chromium, zinc, tin, wdg kpuchie elu ya iji gbochie nchara.
✧ Ngwakọta nke neodymium magnet
Neodymium magnets bụ nke neodymium, ígwè na boron jikọtara ọnụ, nke a na-edekarị dịka Nd2Fe14B.N'ihi nhazi a kapịrị ọnụ yana ikike ịmepụta kristal tetragonal, enwere ike ịtụle magnetik neodymium naanị site na echiche kemịkal.1982, Makoto Sagawa nke Sumitomo Special Metals mepụtara magnet neodymium maka oge mbụ.Kemgbe ahụ, a na-eji nwayọọ nwayọọ wepụ ihe ndọta Nd-Fe-B na magnetik ferrite.
✧ Kedu ka esi eme magnetik neodymium?
Nzọụkwụ 1- Nke mbụ, a na-etinye ihe niile na-eme ka ọ dị mma nke magnet n'ime ọkụ induction na-ekpo ọkụ, na-ekpo ọkụ yana gbazere iji mepụta ngwaahịa alloy.A na-emezi ngwakọta a dị jụụ ka o wee mepụta ingots tupu a ghaa ya n'ime obere ọka n'ime igwe igwe jet.
Nzọụkwụ 2- A na-apịa ntụ ntụ dị oke mma n'ụdị ya yana n'otu oge ahụ a na-etinye ike magnetik na ebu.Magnetism na-abịa site na eriri igwe na-arụ ọrụ dị ka magnet mgbe ọkụ eletrik na-agafe na ya.Mgbe akụkụ ahụ nke magnetik dabara na ntuziaka nke magnetism, nke a na-akpọ magnet anisotropic.
NKWUKWU 3- Nke a abụghị njedebe nke usoro, kama, n'oge a, ihe magnetized na-emebi emebi, ọ ga-abụkwa magnetized ma emechaa mgbe ị na-eme ya.Nzọụkwụ na-esote bụ ka a kpoo ihe ahụ ọkụ, ihe fọrọ nke nta ka ọ bụrụ ruo n'ókè na-agbaze na usoro a na-akpọ Ihe na-esonụ bụ ka ngwaahịa ahụ kpoo ọkụ, ọ fọrọ nke nta ka ọ bụrụ ebe mgbaze na usoro a na-akpọ sintering nke na-eme ka ihe ndọta powdered ejikọta ọnụ.Usoro a na-eme na enweghị ikuku oxygen, ebe inert.
Nzọụkwụ 4- N'ihe fọrọ nke nta ka ọ bụrụ ebe ahụ, ihe a na-ekpo ọkụ na-ajụ oyi ngwa ngwa site na iji usoro a maara dị ka quenching.Usoro jụrụ oyi a ngwa ngwa na-ebelata ebe magnetism ọjọọ ma na-abawanye arụmọrụ.
Nzọpụ 5- N'ihi n'eziokwu na magnetik neodymium siri ike, na-eme ka ha nwee ike imebi ma mebie ha, a ga-ekpuchi ha, kpochaa, akpọnwụọ, ma tinyekwa ya.Enwere ọtụtụ ụdị mmecha dị iche iche nke ejiri magnet neodymium mee ihe, otu n'ime ihe a na-ahụkarị bụ ngwakọta nickel-ọla kọpa-nickel mana enwere ike kpuchie ha na ọla ndị ọzọ yana roba ma ọ bụ PTFE.
Ntụpụ ụkwụ6- Ozugbo emere ya, a na-emegharị ngwaahịa ahụ emechara site na itinye ya n'ime eriri igwe, nke, mgbe ọkụ eletrik na-agafe na ya na-emepụta oghere magnetik ugboro atọ karịa ike dị mkpa nke magnet.Nke a bụ usoro dị irè nke na ọ bụrụ na edoghị magnetik n'ebe ọ nwere ike isi na eriri igwe tụgharịa dị ka mgbọ.
AH MAGNET bụ IATF16949, ISO9001, ISO14001 na ISO45001 onye na-emepụta ihe niile dị elu neodymium magnets na mgbakọ magnetik nwere ahụmịhe karịrị afọ 30 n'ọhịa.Ọ bụrụ na ị nwere mmasị na magnetik neodymium, biko nweere onwe gị ịkpọtụrụ anyị!
