Hoʻohana ʻia nā magnet ikaika i kēia manawa ma kahi ākea o nā noi ma kahi o kēlā me kēia ʻoihana. Aia nā ʻoihana uila, ʻoihana mokulele, ʻoihana olakino a pēlā aku.
No laila pehea e hoʻokolokolo ai i ka maikaʻi a me ka maikaʻi ʻole o NdFeB magnet i ke kūʻai ʻana i nā magnet ikaika NdFeB? He pilikia kēia i ʻike pinepine ʻia e ka poʻe hou, he aha ke ʻano o ka magnet maikaʻi?
I kēia lā, e aʻo mākou iā ʻoe i kekahi mau ʻōlelo aʻoaʻo no ke kūʻai ʻana i nā magnet NdFeB.
1. ʻO ka mea mua, pono ʻoe e ʻike i ke ʻano o ka hana hana o ka magnet āu e makemake ai e hoʻohana?
2. aia nō ke ʻano o ke kaiapuni waho i hiki iā ʻoe ke koho i ka plating pono no ka magnet.
3. nā koi o ka mana magnetic, nā koi wela?
4. ke kūpaʻa mau o ka ikaika magnetic, ke kumu o nā mea maka?
Hiki ke koho i ka mana magnetic ma muli o ka nui o kāu mau kikoʻī e koho i ka papa waiwai, kikoʻī ka mahana, ma lalo o 80 degere, koho N series, ma luna o 80 aia nā H series, kū i ka 120 degere; SH moʻo, kū i ka 150 degere; UH moʻo, kū i ka 180 degere; a me 200 degere ma luna o ka EH a me AH.
ʻO nāʻano hana maʻamau o ka nickel plating a me ka zinc plating, ke gula a me ke kala kala, a me nā mea'ē aʻe, hiki ke hanaʻia e like me nā koi o ka mea kūʻai. Inā loaʻa iā ʻoe nā koi kiʻekiʻe, hiki iā ʻoe ke plating epoxy.
ʻO ka maʻamau, loiloi ʻia ka NdFeB mai ʻelua ʻaoʻao.
1 、Nani
2、Ka hana
ʻIke: inā he nalo nā ʻaoʻao a me nā kihi, inā paʻa ka papa plating, inā paha e kūpono ka nui i nā koi hoʻolālā.
Hana: Aia kahi maʻamau i hoʻohui ʻia no ka hana NdFeB, ʻo nā kuhikuhi nui he huahana ikehu magnetic, coercivity, remanence, etc.
Inā ʻike ʻoe i nā helu i luna, hiki iā ʻoe ke koho i ka magnet NdFeB e kūpono i kāu mau koi.
