Kāohi i ka neodymium magnet
ʻO ke kinikini neodymium magnet
Hoʻoholo ʻia ka kuhikuhi magnetization o ka magnet i ka wā o ke kaʻina hana. ʻAʻole hiki ke hoʻololi i ka kuhikuhi magnetization o ka huahana i hoʻopau ʻia. E ʻoluʻolu e hōʻoia i ka kuhikuhi magnetization makemake o ka huahana.
Hōʻike ʻia ka kuhikuhi magnetization maʻamau i kēia kiʻi ma lalo nei.
ʻO ke kuhikuhi ʻana i ka magnet ka hana mua no nā mea magnet mau loa e like me ka hao hao boron a me nā magnet samarium cobalt e loaʻa ai ka magnetism. Hōʻike ia i nā pole ʻĀkau a me Hema o kahi mea magnet a i ʻole mea hoʻokalakupua. ʻO nā waiwai magnetic o nā mea magnet mau loa i loaʻa mai i kā lākou mau hana kristal maʻalahi. Me kēia deconstruction, hiki i ka mea magnet ke loaʻa i nā waiwai magnetic kiʻekiʻe loa ma lalo o ka hana a kahi māla magnetic waho ikaika, a ʻaʻole e nalowale kona mau waiwai ma hope o ka nalo ʻana o ke kahua magnetic waho.
Hiki ke hoʻololi i ke kuhikuhi magnetization o kahi magnet?
Mai ka hiʻohiʻona o ke kuhikuhi magnetization, hoʻokaʻawale ʻia nā mea magnetic i ʻelua mau ʻāpana: isotropic magnets a me anisotropic magnets. E like me ka manaʻo o ka inoa:
Loaʻa i nā mea magnet isotropic nā waiwai like ʻole ma kēlā me kēia ʻaoʻao a huki pū me ka ʻole.
Loaʻa nā waiwai magnetic mau anisotropic i nā ʻaoʻao like ʻole, a ʻo ke ala e hiki ai iā lākou ke loaʻa nā waiwai magnetic maikaʻi loa / ikaika loa i kapa ʻia ʻo ke kuhikuhi kuhikuhi o nā mea magnetic mau loa.
He kaʻina hana pono no ka hana ʻana i nā mea magnet permanent anisotropic. ʻO nā magnet hou he anisotropic. ʻO ka hoʻonohonoho ʻana o ka lepo magnetic kekahi o nā ʻenehana koʻikoʻi no ka hana ʻana i nā magnet NdFeB kiʻekiʻe. ʻO ka Sintered NdFeB ka mea maʻamau e kaomi ʻia e ka orientation field magnetic, no laila pono e hoʻoholo ʻia ke kuhikuhi kuhikuhi ma mua o ka hana ʻana, ʻo ia ke kuhikuhi magnetization makemake. Ke hana ʻia kahi magnet neodymium, ʻaʻole hiki iā ia ke hoʻololi i ke kuhikuhi o ka magnetization. Inā ʻike ʻia he hewa ke kuhikuhi magnetization, pono e hoʻoponopono hou ʻia ka magnet.
Ka uhi ʻana a me ka pā
Ma muli o ka maikaʻi ʻole o ka corrosion o ka NdFeB magnets, pono ka electroplating e pale i ka corrosion. A laila hiki mai ka nīnau, he aha kaʻu e hoʻopaʻa ai i nā magnet? He aha ka ʻoi aku ka maikaʻi loa? E pili ana i ka hopena maikaʻi loa o ka uhi ʻana o NdFeB ma ka ʻili, ʻo ka mea mua, pono mākou e ʻike i ka NdFeB hiki ke kau ʻia?
He aha nā uhi maʻamau o NdFeB magnets?
ʻO ka nickel coating ikaika ʻo NdFeB he nickel, zinc, epoxy resin a pēlā aku. Ma muli o ka electroplating, ʻokoʻa ke kala o ka ʻili magnet, a ʻokoʻa hoʻi ka manawa mālama no ka manawa lōʻihi.
Ua aʻo ʻia nā hopena o NI, ZN, epoxy resin, a me PARYLENE-C i nā waiwai magnetic o nā magnet NdFeB i ʻekolu mau hopena ma ka hoʻohālikelike. Ua hōʻike ʻia nā hopena: i loko o ka waika, alkali, a me ka paʻakai, polymer material coatings ʻoi aku ka maikaʻi o ka hopena pale i ka magnet, ʻilihune ka resin epoxy, ʻo ka pani ʻana o ka NI ka lua, a ʻoi aku ka maikaʻi o ka uhi ZN:
Zinc: He keʻokeʻo keʻokeʻo ka ʻili, hiki ke hoʻohana ʻia no 12-48 mau hola o ka paʻakai paʻakai, hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana i ke kāpili, (e like me AB glue) hiki ke mālama ʻia no ʻelua a ʻelima mau makahiki inā he electroplated.
Nickel: like me ke kila kila, paʻakikī ka ʻili i ka oxidized i ka lewa, a maikaʻi ke ʻano, maikaʻi ke aniani, a hiki i ka electroplating ke hele i ka hoʻāʻo ʻana i ka paʻakai no 12-72 mau hola. ʻO kona hemahema, ʻaʻole hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana me kekahi kāpili, kahi e hāʻule ai ka uhi. E hoʻolōʻihi i ka oxidation, i kēia manawa ke hoʻohana nui ʻia ke ʻano nickel-copper-nickel electroplating ma ka mākeke no 120-200 mau hola o ka paʻakai paʻakai.

ʻO nā kikoʻī kikoʻī: ka pahu i hoʻopaʻa ʻia me ka magnetically, nā pahu pahu, nā pahu keʻokeʻo a me nā ʻāpana hao, hiki ke pāʻani i ka pale ʻana i ka magnetism i ka wā o ka lawe ʻana.
Nā kikoʻī kikoʻī: I loko o 7-30 mau lā ma hope o ka hōʻoia ʻana i ke kauoha.
