ʻO nā magnet Neodymium nā mea hoʻololi maikaʻi loa i hāʻawi ʻia i ke kālepa, ma nā wahi āpau o ka honua. kū'ē i ka demagnetization ke hoʻohālikelike ʻia me ka ferrite, alnico a me nā magnet samarium-cobalt.
✧ Neodymium magnets VS maʻamau ferrite magnets
ʻO nā mākēneki Ferrite he mau mea metala ʻole e pili ana i ka triiron tetroxide (ka lākiō nuipaʻa paʻa o ka iron oxide i ka ferrous oxide). ʻO ka hemahema nui o kēia mau magnet, ʻaʻole hiki ke hana ʻia ma ka makemake.
ʻAʻole wale ka mana magnetic maikaʻi loa nā neodymium magnets, akā loaʻa nō hoʻi nā waiwai mechanical maikaʻi ma muli o ka hui ʻana o nā metala, a hiki ke hana maʻalahi i nā ʻano like ʻole e kūpono i nā pono like ʻole. ʻO ka hemahema, ʻo nā monomers metala i loko o nā magnet neodymium he maʻalahi ka pala a me ka deteriorate, no laila ua uhi pinepine ʻia ka ʻili me ka nickel, chromium, zinc, tin, etc.
✧ Ka hui ʻana o ka neodymium magnet
Hana ʻia nā magnet neodymium me ka neodymium, ka hao a me ka boron i hui pū ʻia, i kākau pinepine ʻia e like me Nd2Fe14B. Ma muli o ka hoʻonohonoho paʻa a me ka hiki ke hana i nā kristal tetragonal, hiki ke noʻonoʻo ʻia nā magnet neodymium mai kahi ʻano kemika. 1982, ua kūkulu 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 i hana ʻia ai nā magnet neodymium?
KANAWAI 1- ʻO ka mea mua, hoʻokomo ʻia nā mea āpau e hana ai i ka maikaʻi o ka magnet i koho ʻia i loko o kahi umu hoʻomaʻemaʻe hoʻomaʻemaʻe hoʻomaʻemaʻe, hoʻomehana ʻia a hoʻoheheʻe ʻia e hoʻomohala i ka huahana alloy. Hoʻomaʻalili ʻia kēia hui ʻana no ka hoʻomohala ʻana i nā ingots ma mua o ka hoʻoheheʻe ʻia ʻana a lilo i mau ʻano liʻiliʻi i loko o kahi jet mill.
KANAWAI 2- A laila kaomi ʻia ka pauda super-fine i loko o kahi molole a i ka manawa like e hoʻopili ʻia ai ka ikehu magnetic i ka ʻōpala. Hiki mai ka Magnetism mai kahi wili uwea e hana ana ma ke ano he magnet i ka wa e hele ai kekahi au uwila. Ke hoʻohālikelike ʻia ka ʻāpana ʻāpana o ka magnet i nā ʻōlelo aʻoaʻo o ka magnetism, ua kapa ʻia kēia he anisotropic magnet.
KANAWAI 3- ʻAʻole kēia ka pau ʻana o ke kaʻina hana, akā, i kēia manawa ua demagnetized ka mea magnetised a e hoʻopaneʻe ʻia ma hope i ka wā e hana ana pēlā. ʻO ka ʻanuʻu aʻe no ka mea e wela ai, a hiki i ka helu heheʻe ʻana i kahi kaʻina hana i kapa ʻia ʻO ka hana ma lalo nei no ka hoʻomehana ʻana o ka huahana, kokoke a hiki i ka helu heheʻe i loko o kahi kaʻina i kapa ʻia ʻo sintering e hui pū ai nā ʻāpana magneto pauda. Hana ʻia kēia kaʻina hana i kahi hoʻonohonoho inert ʻole o ka oxygen.
KANAWAI 4- Ma kahi kokoke, hoʻomaʻalili koke ka mea wela me ka hoʻohana ʻana i ke ʻano i kapa ʻia ʻo quenching. ʻO kēia kaʻina hana hoʻomaha wikiwiki e hōʻemi i nā wahi o ka magnetism maikaʻi ʻole a hoʻonui pū i ka hana.
KANAWAI 5- Ma muli o ka paʻakikī loa o nā magnet neodymium, hiki iā lākou ke hoʻopōʻino a hōʻino ʻia, pono lākou e uhi ʻia, hoʻomaʻemaʻe, maloʻo, a hoʻopaʻa ʻia hoʻi. Nui nā ʻano hoʻopau like ʻole i hoʻohana ʻia me nā magnet neodymium, ʻo kekahi o nā mea maʻamau ʻo ia ka hui nickel-copper-nickel akā hiki ke uhi ʻia i nā metala ʻē aʻe a me ka rubber a i ʻole PTFE.
HAAWINA6- Ma hope o ka hoʻopaʻa ʻia ʻana, hoʻohana hou ʻia ka huahana i hoʻopaʻa ʻia ma ka hoʻokomo ʻana i loko o kahi coil, a i ka wā e holo ai ka uila i loko o ia mea e hoʻohua ai i kahi māla magnetic ʻekolu manawa ʻoi aku ka ikaika ma mua o ka paʻakikī pono o ka magnet. He hana maikaʻi kēia inā ʻaʻole mālama ʻia ka magnet ma kahi e hiki ke hoʻolei ʻia mai ka pōkā e like me ka pōkā.
ʻO AH MAGNET kahi mea hana IATF16949, ISO9001, ISO14001 a me ISO45001 o nā ʻano mea hana kiʻekiʻe neodymium magnets a me nā hui magnetic me nā makahiki 30 o ka ʻike ma ke kula. Inā makemake ʻoe i nā magnet neodymium, e ʻoluʻolu e kelepona iā mākou!
