He aha nā ʻano like ʻole o NdFeB magnet?

ʻO nā magnet NdFeB, ʻike ʻia hoʻi he neodymium magnets, he mau magnet mau loa i hana ʻia mai kahi huila o neodymium, hao a boron.ʻIke ʻia no ko lākou mau waiwai magnetic ikaika, hoʻohana nui ʻia kēia mau magnet i nā ʻoihana like ʻole, me ka uila, kaʻa a me ka ikehu hou.Aia nā ʻano like ʻole o nā magnet NdFeB, menā mākēneki NdFeB i hoʻopaʻa ʻiaanā mākēneki neodymium sintered.

Sintered neodymium magnetsʻo ia nā ʻano maʻamau o NdFeB magnet.Hana ʻia lākou ma o ke kaʻina hana i kapa ʻia ʻo sintering, kahi e hoʻoheheʻe ʻia ai nā mea maka i loko o ka umu ahi a laila hoʻomaloʻo i mea paʻa.Loaʻa i nā mea hoʻoheheʻe ka hopena i nā ikaika kiʻekiʻe a hiki ke hoʻohana ʻia i nā noi e koi ana i nā māla magnetic ikaika, e like me nā kaʻa uila, nā mea hana a me nā mea hoʻokaʻawale magnetic.

Hana ʻia nā magnet NdFeB i hoʻopaʻa pono ʻia ma ka hui ʻana i ka pauka NdFeB me kahi mea hoʻopili polymer a laila kaomi i ka hui ʻana i ke ʻano i makemake ʻia.Hiki i ke kaʻina hana ke hana i nā magnet me nā ʻano paʻakikī a me nā ʻano nui, e kūpono iā lākou no nā ʻano o nā noi.Nā mākēneki NdFeB i hoʻopaʻa ʻiaHoʻohana maʻamau ʻia i nā ʻoihana kahi koʻikoʻi ka maʻalahi o ka hoʻolālā a me ke kumukūʻai, e like me nā sensor, actuators a me nā mea magnetic.

Loaʻa i nā neodymium magnets sintered a me nā magnet neodymium paʻa i kā lākou pono ponoʻī a me nā hemahema.Ua ʻike ʻia nā magnet neodymium Sintered no ko lākou ikaika magnetic kiʻekiʻe a me ke kūpaʻa ʻana i ka demagnetization, e kūpono ana iā lākou no nā noi koi.Eia nō naʻe, palupalu lākou a hiki i ka corrosion, e koi ana i nā uhi kūikawā e pale aku iā lākou mai nā kumu kūlohelohe.

E pili ana iā mākou

ʻO nā magnet NdFeB i hoʻopaʻa ʻia, ma kekahi ʻaoʻao, ʻoi aku ka maʻalahi i ka hoʻolālā ʻana a hiki ke hana ʻia i nā puke kiʻekiʻe ma ke kumu kūʻai haʻahaʻa.ʻOi aku ka maikaʻi o ke kūpaʻa corrosion a hiki ke hoʻohana ʻia i nā noi ma kahinā mākēneki neodymium sinteredʻaʻole kūpono paha.Eia nō naʻe, ʻoi aku ka haʻahaʻa o ko lākou ikaika i ka hoʻohālikelike ʻia me nā magnet neodymium sintered a ʻaʻole kūpono paha no nā noi kiʻekiʻe.

ʻO ka hōʻuluʻulu manaʻo, ʻelua mau ʻano magnet NdFeB i hoʻopaʻa ʻia a me nā magnet NdFeB i hoʻopaʻa ʻia.ʻIke ʻia nā magnet neodymium Sintered no ko lākou ikaika magnetic kiʻekiʻe a me ke kūʻē ʻana i ka demagnetization, e kūpono ana iā lākou no nā noi koi, ʻoiai.nā mākēneki NdFeB i hoʻopaʻa ʻiahāʻawi i ka maʻalahi o ka hoʻolālā a me ke kumukūʻai.He mea nui ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o kēia mau ʻano ʻelua o nā magnet NdFeB i ke koho ʻana i ka magnet kūpono no kahi noi kikoʻī.
