Hoʻohālikelike Hana Ma waena o nā Mākēneki Kanal Neodymium a me nā ʻano Magnet ʻē aʻe

ʻO ka "Superhero" o nā Magnets: No ke aha ʻo Arc NdFeBKanal MagnetsKa mana loa?

Aloha kākou! I kēia lā, e kamaʻilio kākou e pili ana i nā mea magnet - ʻo kēia mau mea liʻiliʻi maʻamau a hoihoi. Ua ʻike anei ʻoe? ʻO nā ʻokoʻa ma waena o nā magnet like ʻole e like me nā mea ma waena o nā smartphones a me nā kelepona maʻamau! ʻOi aku ka nui o nā kaha kaha NdFeB (Neodymium Iron Boron) i ʻike hou ʻia - ʻo lākou ka "Iron Man" o ka honua magnet. No laila, pehea ko lākou kupaianaha? He aha ka mea e kū ai lākou mai nā mea magnet ʻē aʻe? Mai hopohopo, e wāwahi mākou i kēlā me kēia pae.

 

1. E hui me ka ʻohana Magnet

ʻO ka mea mua, e hoʻolauna kākou i nā "ʻohana nui ʻehā" o nā magnet:

NdFeB Mākēneki - ʻO nā "mea hoʻokō kiʻekiʻe" o nā magnet

I kēia manawa, ʻo ka magnet mau loa ikaika loa i ka honua

Hana ʻia me ka neodymium, hao, a me ka boron

E like me nā "bodybuilders" o nā mea magnet - ikaika loa akā he wela iki

Nā Mākēneki Ferrite - ʻO nā "mea hana"

 

ʻO ka koho waiwai nui loa

Hana ʻia mai ka hao oxide a me ka strontium/barium pūhui

ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion akā ʻoi aku ka nāwaliwali o ka ikaika magnetic

AlNiCo Magnets - ʻO nā "mea kahiko kahiko"

ʻO kekahi o nā mea magnet paʻa kahiko loa

Kūlana wela kūlana

E like me nā mea pāʻani evergreen me nā mana anti-demagnetization ikaika

SmCo Magnets - ʻO nā "elites hanohano"

 

ʻO kekahi mea kiʻekiʻe-hana rare earth magnet

Paʻa ka wela a me ka ʻōpala

ʻOi aku ka maikaʻi ma mua o NdFeB, e mālama ana i nā noi uku

 

2. Na Mana Nui o NdFeB Channel Magnets

 

No ke aha i kapa ʻia ai lākou ʻo "Iron Man"? No ka mea, loaʻa iā lākou kēia mau mana kupaianaha:

 

Ka Ikaika Magnetic Kaulike ole

10 mau manawa ʻoi aku ka ikaika ma mua o nā magnet ferrite! (E noʻonoʻo i kahi mea hāpai kaumaha vs. kahi keiki kula haʻahaʻa)

Loaʻa ka Remanence i ka 1.0-1.4 Tesla (hiki wale nā ​​​​magnets maʻamau i ka 0.2-0.4)

ʻO ka mana anti-demagnetization maikaʻi loa, e like me ka cockroach hiki ʻole ke luku ʻia

 

ʻO ka hoʻolālā ʻana i ke ala ala

Hiki i ka hoʻolālā Groove ke hoʻomalu i ka mana magnetic, e like me ka hāʻawi ʻana i ka hoʻokele GPS magnetism

ʻOi aku ka paʻa paʻa, ʻaʻole hiki ke "haʻi"

Maʻalahi e hoʻouka, e like me ka hui ʻana i nā poloka Lego

 

ʻO ke aliʻi o ka hana uku

ʻOiai ʻoi aku ka kiʻekiʻe o ke kumukūʻai ma mua o ka ferrite, hāʻawi ia i ke kumu kūʻai haʻahaʻa loa no kēlā me kēia ʻāpana magnetic

Loaʻa i ka magnetism ikaika me ka liʻiliʻi liʻiliʻi, e mālama i nā wahi a me ke kālā

 

3. I ka manawa hea e koho ai i ka "Superhero"?

 

E koho i NdFeB Channel Magnets inā:

He palena ʻole ka wahi akā makemake ʻia ka magnetism ikaika (e laʻa, nā pepeiao pepeiao uea ʻole, nā kaʻa uila uila)

Pono ka hoʻomalu ʻana i ke kahua magnetic (e laʻa, nā mea hoʻokele magnetic, nā mea ʻike)

ʻO ka neʻe pinepine ʻana (e laʻa, nā motika EV, nā kaʻa drone)

ʻO ka hoʻolālā māmā ka mea nui (nā lako aerospace)

 

E koho i nā magnet ʻē aʻe inā:

Kaiapuni wela loa (ma luna o 200°C)

Nā kūlana ʻino loa (nā lako kai)

Puke kālā no ka hana nui

Paʻa loa nā mea hana i nā loli wela

 

4. Manaʻo kōkua no ka hoʻohana ʻana i nā Mākēneki NdFeB

 

Hāʻawi iā lākou i "ʻaʻahu":Ka uhi ʻana o ka ʻili (nickel, zinc, a i ʻole epoxy) no ka pale ʻana i ka ʻōpala

He "puʻuwai aniani" lākou:E mālama pono i ka wā o ka hoʻokomo ʻana - he palupalu lākou

Paʻa wela:Hiki i nā wela kiʻekiʻe ke hoʻoulu i ka "nalo ʻiʻo" mau loa (demagnetization)

He mea nui ke kuhikuhi: Pono e magnetized e like me ka hoʻolālā orientation

E mālama me ka akahele:Hiki i nā māla magnetic ikaika ke hoʻopili i nā kāleka hōʻaiʻē, nā wati; e mālama i nā mea hoʻohana pacemaker

 

5. He aha ka mea e hiki mai ana?

 

Nā mana ikaika loa:Ke kūkulu nei nā kānaka ʻepekema i nā māka hou ikaika loa

ʻOi aku ka pale wela:E hoʻemi iki iā lākou i nā wela kiʻekiʻe

Nā hoʻolālā akamai:Ke hoʻohana nei i nā lolouila no ka hoʻopololei ʻana i nā kūkulu ʻana o ke kahawai

Nā hāʻina ʻōmaʻomaʻo: Ka hoʻomaikaʻi ʻana i ka ʻenehana hana hou, e hōʻemi ana i ka hoʻohana ʻana i ka honua

ʻOi aku ke kumukūʻai: Hoʻonui i ka hana i ka hoʻohaʻahaʻa i nā kumukūʻai

 

Nā Manaʻo Hope

ʻO nā mea hoʻokalakupua NdFeB e like me nā "poʻokela holoʻokoʻa" o ka honua magnet, ka koho mua no ka nui o nā noi ʻenehana kiʻekiʻe. Akā ʻaʻole lākou mana loa - e like me ʻoe ʻaʻole e hoʻohana i kahi kaʻa haʻuki e huki i nā waiwai, ʻo ke kī ke koho ʻana i ka mea hana kūpono no ka hana.
