ʻO nā magnet Neodymium nā magnet irreversible maikaʻi loa i hāʻawi ʻia ma ke kālepa, ma nā wahi āpau o ka honua. ke kū'ē nei i ka demagnetisation i ka hoʻohālikelike ʻia me nā magnet ferrite, alnico a me samarium-cobalt.
✧ Nā mākēneki Neodymium VS nā mākēneki ferrite maʻamau
ʻO nā magnet Ferrite he mau magnet mea ʻaʻole metala i hoʻokumu ʻia ma ka triiron tetroxide (lakio nui paʻa o ka hao oxide i ka ferrous oxide). ʻO ka hemahema nui o kēia mau magnet, ʻaʻole hiki ke hana ʻia i ka makemake.
ʻAʻole wale ka mana magnetic maikaʻi loa o nā magnet Neodymium, akā he mau waiwai mechanical maikaʻi hoʻi ma muli o ka hui ʻana o nā metala, a hiki ke hana maʻalahi ʻia i nā ʻano like ʻole e kūpono i nā pono like ʻole. ʻO ka hemahema, ʻo ia ka maʻalahi o ka popo a me ka palaho ʻana o nā monomers metala i loko o nā magnet neodymium, no laila ua uhi pinepine ʻia ka ʻili me ka nickel, chromium, zinc, tin, a me nā mea ʻē aʻe e pale aku i ka popo.
✧ Ka haku mele ʻana o ka magnet neodymium
Hana ʻia nā magnet Neodymium me ka neodymium, ka hao a me ka boron i hoʻohui ʻia, i kākau pinepine ʻia ʻo Nd2Fe14B. Ma muli o ke ʻano paʻa a me ka hiki ke hana i nā kristal tetragonal, hiki ke noʻonoʻo ʻia nā magnet neodymium mai kahi manaʻo kemika wale nō. 1982, ua hoʻomohala ʻo Makoto Sagawa o Sumitomo Special Metals i nā magnet neodymium no ka manawa mua. Mai ia manawa, ua hoʻopau mālie ʻia nā magnet Nd-Fe-B mai nā magnet ferrite.
✧ Pehea e hana ʻia ai nā magnet neodymium?
KAʻANUʻU 1- ʻO ka mea mua, ua waiho ʻia nā mea āpau e hana i ke ʻano i koho ʻia o ka magnet i loko o kahi umu hoʻoheheʻe mīkini hoʻomaʻemaʻe, hoʻomehana ʻia a hoʻoheheʻe ʻia e hana i ka huahana alloy. A laila hoʻomaʻalili ʻia kēia hui ʻana e hana i nā ingots ma mua o ka wili ʻia ʻana i loko o nā hua liʻiliʻi i loko o kahi wili jet.
KAʻANUʻU 2- A laila kaomi ʻia ka pauka maikaʻi loa i loko o kahi ʻōmole a i ka manawa like e hoʻopili ʻia ai ka ikehu magnetic i ka ʻōmole. Loaʻa ka Magnetism mai kahi wili o ke kaula e hana ana ma ke ʻano he magnet ke hoʻoili ʻia kahi au uila ma o ia mea. Ke kūlike ke ʻano o ka ʻāpana o ka magnet me nā kuhikuhi o ka magnetism, ua kapa ʻia kēia he magnet anisotropic.
KAʻANUʻU 3- ʻAʻole kēia ka hopena o ke kaʻina hana, akā, i kēia manawa ua hoʻohemo ʻia ka magnetized i ka mea a e magnetized ʻia ma hope aku i ka wā e hana ana pēlā. ʻO ka hana aʻe, ʻo ia ka hoʻomehana ʻana i ka mea, kokoke a hiki i ka pae heheʻe i loko o kahi kaʻina hana i kapa ʻia ʻO ka hana aʻe, ʻo ia ka hoʻomehana ʻana i ka huahana, kokoke a hiki i ka pae heheʻe i loko o kahi kaʻina hana i kapa ʻia ʻo sintering e hoʻohui pū ai nā ʻāpana magnet pauka. Hana ʻia kēia kaʻina hana ma kahi hoʻonohonoho ʻole oxygen, inert.
KAʻANUʻU 4- Ma laila wale nō, hoʻomaʻalili koke ʻia ka mea i hoʻomehana ʻia me ka hoʻohana ʻana i kahi ʻano i kapa ʻia ʻo quenching. Hoʻemi kēia kaʻina hana hoʻomaʻalili wikiwiki i nā wahi o ka magnetism maikaʻi ʻole a hoʻonui pū i ka hana.
KAʻANUʻU 5- Ma muli o ka paʻakikī o nā magnet neodymium, e maʻalahi ai lākou i ka hōʻino a me ka hōʻino ʻana, pono e uhi ʻia, hoʻomaʻemaʻe ʻia, hoʻomaloʻo ʻia, a hoʻopili ʻia. Nui nā ʻano hoʻopau like ʻole i hoʻohana ʻia me nā magnet neodymium, ʻo kekahi o nā mea maʻamau he hui nickel-copper-nickel akā hiki ke uhi ʻia i nā metala ʻē aʻe a me ka rubber a i ʻole PTFE.
KAʻANUʻU 6- Ke hoʻopili ʻia, hoʻopili hou ʻia ka huahana i hoʻopau ʻia ma ke kau ʻana i loko o kahi wili, kahi, i ka wā e hele ai ke au uila ma o ia mea e hoʻopuka ai i kahi kahua magnetic ʻekolu manawa ʻoi aku ka ikaika ma mua o ka paʻakikī e pono ai o ka magnet. He hana kūpono loa kēia inā ʻaʻole mālama ʻia ka magnet ma kahi e hiki ai ke hoʻolei ʻia mai ka wili e like me ka pōkā.
ʻO AH MAGNET kahi mea hana i hōʻoia ʻia e IATF16949, ISO9001, ISO14001 a me ISO45001 o nā ʻano magnet neodymium hana kiʻekiʻe a me nā ʻākoakoa magnetic me ka ʻoi aku o 30 mau makahiki o ka ʻike ma ke kahua. Inā makemake ʻoe i nā magnet neodymium, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou!
