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.

✧ 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.
NKWUKWU 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, ọ 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 wụpụ ya-dị ka mgbọ.
AH MAGNET bụ IATF16949, ISO9001, ISO14001 na ISO45001 onye na-emepụta ihe niile dị elu neodymium magnets na mgbakọ magnetik nwere ahụmahụ karịrị afọ 30 n'ọhịa. Ọ bụrụ na ị nwere mmasị na magnetik neodymium, biko nweere onwe gị ịkpọtụrụ anyị!
