Papa 35 SmCo Magnet

ʻO ka wehewehe pōkole:

ʻO ka māka 35 SmCo magnet a i ʻole grade 35 Samarium Cobalt magnet i kēia manawa ka ikaika loa o ka Samarium Cobalt magnet ma ka mākeke. He mea kūikawā SmCo kiʻekiʻe e hāʻawi ana i kahi huahana ikehu ʻoi aku ka maikaʻi, ka pale ʻana i ka corrosion, ke kūpaʻa wela maikaʻi a me ke kūpaʻa demagnetization wela.

E hoʻouna i ka leka uila iā mākou

Huahana Huahana

I ka wā ma mua, ʻo ka papa 30 a i ʻole 32 ka helu Samarium Cobalt kiʻekiʻe loa i hiki i nā mea hoʻolako magnet SmCo a pau ke hāʻawi. 35 papa Samarium Cobalt ua hoʻomalu ʻia e kekahi mau hui US, e like me Arnold (Arnold Magnetic Technologies, grade RECOMA 35E), EEC (Electron Energy Corporation, 34 grade SmCo). ʻO Horizon Magnetics kekahi o nā hui magnet liʻiliʻi loa e hiki ke hoʻolako i nā māka 35 SmCo ma ka nui nui me Br > 11.7 kGs, (BH) max > 33 MGOe a me Hcb >10.8 kOe.

Nā ʻano nui

1. ʻOi aku ka mana akā haʻahaʻa ke kaumaha. No Samarium Cobalt, hoʻonui kēia papa i ka ikaika o ka ikehu i mea e kūpono ai i kekahi mau noi koʻikoʻi kahi mea nui ka liʻiliʻi a me ka hoʻomaikaʻi ʻana i ka hana.

2. Paʻa kiʻekiʻe. No kēia papa, ʻoi aku ka kiʻekiʻe o BHmax, Hc a me Br ma mua o nā māka kiʻekiʻe o Sm2Co17 magnet e like me 32 grade, a ʻoi aku ka maikaʻi o ka paʻa ʻana o ka mahana a me ka mahana hana kiʻekiʻe.

Hoʻohana ʻia

1. Nā Kaʻa Kaʻa: Ma nā kaʻa kaʻa, ʻo ia ke kumu nui e lanakila ai i ka hoʻokūkū ikaika ma o ka hoʻohana ʻana i nā mea hana hou e hoʻonui ai i ka torque a me ka wikiwiki me ka pūʻolo liʻiliʻi a paʻa loa.

2. Ke hoʻololi nei i ka hana kiʻekiʻe Neodymium magnets: I ka nui o ka manawa, ʻoi aku ka maikaʻi o ke kumukūʻai Samarium Cobalt ma mua o ka neodymium magnet, no laila ua hoʻohana nui ʻia ʻo Samarium Cobalt magnet no nā mākeke kahi Neodymium magnet ʻaʻole lawa e hoʻokō i ke koi koʻikoʻi. He ʻuʻuku liʻiliʻi ko ka honua laha ʻole ʻo Dy (Dysprosium) a me Tb (Terbium) i nā ʻāina liʻiliʻi akā pono no nā mea kiʻekiʻe Neodymium magnets me ka pae AH, EH a i ʻole UH, ka hapa nui o ia mau mea i hoʻohana ʻia i nā kaʻa uila he nui. Ua ʻike ʻo 2011 i ka piʻi nui ʻana o nā mea makakumu kūʻai ʻāina rare. Ke piʻi aʻe nei ke kumu kūʻai o ka honua laʻa, 35 grade Samarium Cobalt, a i ʻole 30 grade hiki ke lilo i mea ʻoi aku ka maikaʻi loa no nā mea hoʻohana magnet e noho mau ke kumukūʻai ma mua o ko lākou mau mea hoʻokūkū. Ma muli o ke kūpaʻa maikaʻi o ka mahana, ʻoi aku ka maikaʻi o ka BHmax no ka papa 35 Samarium Cobalt ma mua o N42EH a i ʻole N38AH o Neodymium magnet ma nā mahana ma mua o 150C degere, hiki ke hōʻoia ʻia ma kaNā ʻĀpana Hysteresis.
