Neodymium Magnet, i ʻike ʻia ʻoNdFeb Neodymium magnet, he ʻōnaehana kristal tetragonal i hana ʻia e neodymium, hao a me ka boron.Ua ʻoi aku ka ikaika o kēia magnet ma mua oSmCo mau Magnets, ka magnet nui loa o ka honua ia manawa.Ma hope mai, ʻo ka hoʻomohala kūleʻa o ka pauka metallurgy, ua hoʻomohala maikaʻi ʻo General Motors i ke ʻano hoʻoheheʻe rotary jet, hiki ke hana i nā magnet NdFeb.ʻO kēia ʻano magnet ka lua wale nō i ka zero holmium permanent magnet, ʻo ia hoʻi nā magnet honua laha i hoʻohana mau ʻia.Hoʻohana nui ʻia nā magnet NdFeb i nā huahana uila e like me nā paʻa paʻa, kelepona paʻa, nā pepeiao a me nā mea hana pākaukau.
ʻO NdFeb magnet, ʻike ʻia hoʻi he ʻano mea magnet mau loa, he ʻanoMea Mākēnekihana ʻia a sintered mai praseodymium neodymium ma ke ʻano he kumu kumu.
ʻO ka hoʻohana ʻana i ka magnet NdFeb i ka leo kani: no ka mea, ʻo kāna mea nui he neodymium a me ka mea hoʻohui i ka hao (fe-co), no laila ua kapa ʻia ʻo NdFeb.He ʻano magnet mau loa ia me ka hana maikaʻi loa, i hoʻohana nui ʻia i ka ʻoihana uila, hana mīkini a me nā mea kani.
Loaʻa iā NdFeb nā hiʻohiʻona o ka remanence kiʻekiʻe, kiʻekiʻe coercivity a me ka ikaika kiʻekiʻe magnetic field.Hiki iā ia ke mālama i ka magnetism no ka manawa lōʻihi i ka wela kiʻekiʻe me ka ʻole o ka oxygen.Paʻa wela maikaʻi;Loaʻa iā ia ke kūpaʻa kemika maikaʻi a me ke kūpaʻa corrosion kiʻekiʻe.ʻO kāna hiʻohiʻona nui hiki ke hoʻopiha ʻia me ka nui o nā magnets (a ʻoi aku ma mua o 100kg), a he liʻiliʻi loa ke kahua demagnetic (negligible).No laila, loaʻa iā ia kahi manaʻo noiʻi ākea ma ke kahua o ka māla magnetic kiʻekiʻe.
I kēia manawa, ʻo nā huahana home ka mea nui: hf50 ~ 70mm kikoʻī kikoʻī, hf80 ~ 120mm kikoʻī kikoʻī a me smd moʻo ʻekolu ʻano huahana.ʻOi aku ka nui o ke kumukūʻai o nā huahana ma mua o RMB 20,000 no ka kilo i RMB 40,000.
No ka mea ua hoʻohana nui ʻia ka huahana a nui ka dosage, ʻoi aku ka nui o ka hoʻohana ʻana i nā haneli haneli mau tons i kēlā me kēia makahiki.Eia naʻe, he liʻiliʻi wale nō nā ʻāina o ka honua e hiki ke hana i kēia Material hana hou me ka ʻenehana kiʻekiʻe a me ka waiwai hoʻohui kiʻekiʻe, "Mea Mākēneki Kiʻekiʻe“.
