Kedu ihe bụ Neodymium Magnets

Kedu ka esi eme Magnet Neodymium?

Usoro abụọ a na-eji emepụta magnetik neodymium bụ njikọ na njikọta. Njirimara nke magnetik emechara dịgasị iche dabere n'otú e si emepụta ha na sintering bụ ụzọ kachasị mma nke ụzọ abụọ ahụ.

Otu esi eme Magnet Neodymium

Na-egwu egwu

1. Na-agbaze:

   A na-atụle Neodymium, Ígwè na boron ma tinye n'ime ọkụ induction oghere iji mepụta alloy. A na-agbakwunye ihe ndị ọzọ maka akara ule dị iche iche, dị ka cobalt, ọla kọpa, gadolinium, na dysprosium iji nyere aka na nguzogide corrosion. A na-emepụta ikpo ọkụ site na mmiri ọkụ eletrik n'ime oghere iji mee ka ihe ndị na-emerụ emerụ pụta. Ngwakọta neo alloy dị iche iche maka onye nrụpụta na ọkwa nke neodymium magnet.

2. Ntụ ntụ:

   A na-eme ka alloy gbazere dị jụụ wee ghọọ ingots. A na-egweri ingots n'ime ikuku nitrogen na argon iji mepụta ntụ ntụ nwere obere micron. A na-etinye ntụ ntụ neodymium na hopper maka ịpị.

3. Ịpị:

   A na-agbanye ntụ ntụ n'ime anwụ dị ntakịrị karịa ọdịdị a chọrọ site na usoro a maara dị ka iwe iwe na okpomọkụ nke ihe dịka 725 ° C. Ụdị dị ukwuu nke ọnwụ ahụ na-enye ohere maka nkwụsịtụ n'oge usoro nsị. N'oge ịpị, a na-ekpughe ihe ahụ na oghere magnetik. A na-etinye ya na ọnwụ nke abụọ ka a pịa ya ka ọ bụrụ ọdịdị sara mbara iji kwado magnetization yiri ntụziaka nke ịpị. Ụzọ ụfọdụ gụnyere ihe nrụnye iji mepụta oghere ndọta n'oge ịpị iji kwado ihe ndị ahụ.

   Tupu a tọhapụrụ magnet a na-agbanye, ọ na-enweta ihe na-eme ka ọ ghara imebi ya ka ọ hapụ ya ka ọ mepụta magnetik akwụkwọ ndụ akwụkwọ ndụ, nke na-adị mfe crumbles ma nwee ihe ndọta na-adịghị mma.

4. Na-agụ:

   Ịkụkọ, ma ọ bụ frittage, na-ejikọta ma mepụta magnetik akwụkwọ ndụ akwụkwọ ndụ na-eji okpomọkụ dị n'okpuru ebe mgbaze ya iji nye ya ihe ndọta ikpeazụ ya. A na-enyocha usoro a nke ọma na ikuku ikuku na-enweghị ikuku. Oxides nwere ike imebi ọrụ magnetik neodymium. A na-agbanye ya na okpomọkụ na-eru 1080 ° C mana n'okpuru ebe mgbaze ya iji mee ka ụmụ irighiri ihe na-arapara n'ahụ ibe ha.

   A na-etinye ihe nkwụsịtụ iji mee ka magnetọ ahụ dị ngwa ngwa wee belata usoro, nke bụ ụdị dị iche iche nke alloy nwere àgwà magnetik adịghị mma.

5. Ịrụ igwe:

   A na-eji ọla diamond ma ọ bụ ngwaọrụ ịkpụ waya na-akpụzi ha ka ọ dị mma.

6. Ịkwasa na mkpuchi:

   Neodymium oxidizes ngwa ngwa ma na-adịkarị mfe corrosion, nke nwere ike wepụ ihe ndọta ya. Dị ka ihe nchebe, a na-ekpuchi ha na plastik, nickel, ọla kọpa, zinc, tin, ma ọ bụ ụdị mkpuchi ndị ọzọ.

7. Magnetization:

   Ọ bụ ezie na ihe ndọta ahụ nwere ntụzịaka nke ndọta, ọ bụghị magnetized na a ga-ekpughere ya nkenke n'ime oghere magnetik siri ike, nke bụ eriri waya nke gbara magnet gburugburu. The magnetizing na-agụnye capacitors na elu voltaji na-emepụta ike ugbu a.

8. Nyocha ikpeazụ:

   Igwe ihe nleba anya dijitalụ na-enyocha akụkụ ya yana teknụzụ fluorescence x-ray na-enyocha ọkpụrụkpụ nke plain ahụ. A na-anwale mkpuchi ahụ n'ụzọ ndị ọzọ iji hụ na ịdị mma na ike ya. A na-anwale usoro BH site na eserese hysteresis iji kwado nkwalite zuru oke.

Nkwekọrịta

Nkwekọrịta, ma ọ bụ mkpakọ njikọ, bụ usoro ịnwụ anwụ nke na-eji ngwakọta nke neodymium ntụ ntụ na ihe na-ejikọta epoxy. Ngwakọta ahụ bụ ihe ndọta 97% na 3% epoxy.

A na-agbakọta ngwakọta epoxy na neodymium na mpempe akwụkwọ ma ọ bụ wepụ ya ma gwọọ ya na oven. Ebe ọ bụ na a na-agbanye ngwakọta ahụ n'ime anwụ ma ọ bụ tinye site na extrusion, magnet nwere ike ịkpụzi ka ọ bụrụ ọdịdị dị mgbagwoju anya na nhazi. Usoro nchikota nke mkpakọ na-emepụta magnetik nwere nnabata siri ike na ọ dịghị achọ ọrụ nke abụọ.

Ihe ndọta jikọtara mkpakọ bụ isotropic na enwere ike ịmegharị ya n'akụkụ ọ bụla, nke gụnyere nhazi ọtụtụ polar. Njikọ epoxy na-eme ka magnetik sie ike nke ọma ka a na-egweri ma ọ bụ techie ya mana a gaghị agbapụ ya ma ọ bụ kpatụ ya.

Radial Sintered

Ihe ndọta neodymium gbakwasara radially bụ ihe ndọta kachasị ọhụrụ na ahịa ndọta. Usoro maka imepụta magnetik radial aligned ka amatala kemgbe ọtụtụ afọ mana ọ naghị efu ọnụ. Mmepe teknụzụ ndị na-adịbeghị anya emewo ka usoro mmepụta ihe na-eme ka ọ dị mfe imepụta magnet na-adabere na radially.

Usoro atọ maka imepụta magnetik neodymium radial aligned bụ anisotropic molding, na-ekpo ọkụ na-akụ azụ azụ extrusion, na radial rotating ubi alignment.

Usoro nchikota na-eme ka a mara na enweghi ntụpọ adịghị ike na nhazi magnet.

Àgwà pụrụ iche nke ihe ndọta radially aligned bụ ntụzịaka nke oghere ndọta, nke na-agbatị gburugburu ebe ndọta ahụ. Ogwe ndịda nke magnet dị n'ime ime mgbanaka ahụ, ebe ogwe ugwu dị na gburugburu ya.

Ihe ndọta neodymium gbakwasara radially bụ anisotropic ma bụrụ nke magnetized site n'ime mgbanaka ahụ gaa n'èzí. Magnetization Radial na-abawanye ike ndọta mgbanaka ma nwee ike ịkpụzi ya n'ọtụtụ usoro.

Enwere ike iji magnetik neodymium mgbanaka radial maka moto mekọrịtara ọnụ, moto steepụ, na moto brushless DC maka ụlọ ọrụ ụgbọ ala, kọmpụta, eletrọnịkị na nkwukọrịta.
