Pehea ka lōʻihi o ka neodymium magnets

NdFeB magnets, ʻike ʻia hoʻi ʻo NdFeB magnets, he mau kristal tetragonal i hana ʻia me ka neodymium, hao, a me ka boron (Nd2Fe14B). ʻO nā magnet neodymium ka mea magnet mau loa i loaʻa i kēia lā a me nā mea hoʻohana maʻamau i hoʻohana pinepine ʻia.

Pehea ka lōʻihi e hiki ai i nā waiwai mākēneki o NdFeB mau mākēneki?

He kiʻekiʻe loa ka ikaika hoʻokalakupua o NdFeB, a ʻaʻohe demagnetization a me nā hoʻololi magnetic ma lalo o ke kaiapuni kūlohelohe a me nā kūlana maʻamau. Ke manaʻo nei he pololei ke kaiapuni, ʻaʻole e nalowale nā ​​magnets i ka hana ma hope o ka hoʻohana lōʻihi ʻana. No laila i ka hoʻohana pono ʻana, ʻike pinepine mākou i ka mana o ka mea manawa ma ka magnetism.

He aha nā mea e pili ai i ke ola lawelawe o nā magnet neodymium i ka hoʻohana ʻana i kēlā me kēia lā o nā magnet?

ʻElua mau kumu āu e pili pono ai i ke ola lawelawe o ka magnet.

ʻO ka mua ka wela. E mālama pono i kēia pilikia i ke kūʻai ʻana i nā magnet. Hoʻohana nui ʻia nā mākau N series ma ka mākeke, akā hiki iā lākou ke hana i kahi kaiapuni ma lalo o 80 degere. Inā ʻoi aku ka mahana ma mua o kēia mahana, e nāwaliwali ka magnetism a i ʻole demagnetized loa. Ma muli o ka hiki ʻana o ka mākēneki waho o ka magnet i ka saturation a ua hoʻokumu i nā laina induction magnetic, i ka wā e piʻi ai ka mahana o waho, e luku ʻia ke ʻano hana maʻamau i loko o ka magnet. Hoʻemi ia i ka ikaika hoʻoikaika koʻikoʻi o ka magnet, ʻo ia hoʻi, hoʻololi ka huahana ikehu nui me ka mahana, a hoʻololi pū ka huahana o ka waiwai Br a me ka waiwai H.

ʻO ka lua ka corrosion. ʻO ka maʻamau, ʻo ka ʻili o nā magnet neodymium e loaʻa kahi papa o ka uhi. Inā pōʻino ka uhi ʻana o ka magnet, hiki i ka wai ke komo pololei i loko o ka magnet, a laila e hoʻoheheʻe ʻia ka magnet a laila e alakaʻi i ka emi ʻana o ka hana magnetic. Ma waena o nā mea magnet a pau, ʻoi aku ka kiʻekiʻe o ka ikaika o ka corrosion o nā magnet neodymium ma mua o nā mea magnet ʻē aʻe.

Makemake au e kūʻai i nā neodymium magnets lōʻihi, pehea wau e koho ai i kahi mea hana?

Hana ʻia ka hapa nui o nā magnet neodymium ma Kina. Inā makemake ʻoe e kūʻai i nā huahana kiʻekiʻe, pili ia i ka ikaika o ka hale hana. Ma ke ʻano o ka ʻenehana hana, nā lako hoʻāʻo, ka holo ʻana o ke kaʻina hana, ke kōkua ʻenekinia, ke keʻena QC a me nā palapala ʻōnaehana hoʻokele maikaʻi hiki ke hoʻokō i nā kūlana honua. Hoʻokō wale ʻo Fuzheng i nā kūlana i luna aʻe, no laila kūpono ke koho iā mākou i mea hana i nā neodymium magnet wahine.
