Anisotropic Sintered NdFeB NIB Ring Magnet Mau

Nā Mākēneki NIB Sintered
Loaʻa ka ikaika kiʻekiʻe loa o nā magnet Sintered NIB akā ua kaupalena ʻia i nā geometries maʻalahi a hiki ke palupalu. Hana ʻia lākou ma ke kaomi ʻana i nā mea maka i mau poloka, a laila hele i loko o kahi kaʻina hana hoʻomehana paʻakikī. A laila ʻoki ʻia ka poloka e like me ke ʻano a uhi ʻia i mea e pale ai i ka pala. He anisotropic maʻamau nā magnet sintered, ʻo ia ka mea makemake lākou i ke kuhikuhi o kā lākou māla magnetic. ʻO ka hoʻopaneʻe ʻana i ka magnet e kūʻē i ka "palaoa" e hōʻemi i ka ikaika o ka magnet a hiki i 50%.

Demagnetization
ʻO nā mea hoʻokalakupua NIB he mau magnet mau loa, no ka mea, nalowale lākou i ka magnetism, a i ʻole degauss maoli, ma kahi o 1% i kēlā me kēia kenekulia. E hana maʻamau lākou i loko o ka pae wela o-215 ° Fto 176 ° F (-138 ° C a 80 ° ℃). No nā noi e koi ana i kahi ākea ākea ākea, hoʻohana ʻia nā magnet Samarium Cobalt (SmCo).

Nā uhi
No ka mea, ʻo ka NIB sintered ʻaʻole i hoʻopili ʻia e ʻino a ʻūlū me ka ʻike ʻana i ka lewa, kūʻai ʻia lākou me kahi uhi pale. ʻO ka uhi maʻamau i hana ʻia me ka nickel, ʻoiai ʻo nā mea hoʻonaninani ʻē aʻe i kūʻai ʻia e hāʻawi i ke kūʻē i ka wela kiʻekiʻe, ka haʻahaʻa kiʻekiʻe, ka paʻakai paʻakai, nā solvents a me nā kinoea.

Papa
Hiki mai nā mākēneki NIB i nā māka like ʻole, e pili ana i ka ikaika o kā lākou mau mākēneki, mai ka N35 (nāwaliwali a me ka liʻiliʻi loa o ke kumukūʻai) a i ka N52 (ikaika loa, ʻoi aku ka pipiʻi a ʻoi aku ka brittle). 52/35 = 1.49). I ka Us, he mea maʻamau ka loaʻa ʻana o nā mea hoʻohana i nā mea hoʻohana ma ka pae N40 a i ka N42. I ka hana nui, hoʻohana pinepine ʻia ka N35 inā ʻaʻole manaʻo nui ka nui a me ke kaumaha no ka mea he emi ke kumu kūʻai. ʻO ka nui a me ke kaumaha ka mea koʻikoʻi, hoʻohana maʻamau nā māka kiʻekiʻe. Aia ke kumukūʻai ma ke kumu kūʻai o nā mea hoʻokalakupua kiʻekiʻe loa no laila ʻoi aku ka maʻamau o ka ʻike ʻana i nā magnet N48 a me N50 i hoʻohana ʻia i ka hana me N52.
