Intee in le'eg bay u leedahay nuugista magnets-ka xooggan ee NdFeB?

2023-02-20

Sidee Ma xoog badan tahay nuugista magnets-ka ndFeB?

 

NdFeB magnets hadda waa birneedka joogtada ah ee ugu awoodda badan. Magnets NdFeB waa hadda magnet-yada ganacsi ahaan ugu badan ee la heli karo. Waxaa loo yaqaan boqorka ee magnetismka. Waxay leeyihiin sifooyin birlab ah oo aad u sarreeya iyo ugu badnaantooda Alaabta tamarta magnetic (BHmax) waxay ka badan tahay 10 jeer ferrite. Sidoo kale waa magnetka dhulka naadirka ah ee inta badan la isticmaalo, iyo iyada waxaa loo isticmaalaa qaybo badan iyo qalab sida magnet joogto ah ee our caadiga ah matoorada, disk-yada, iyo sawir-qaadista magnet-ka.

 

Ay iska leedahay mashiinada ayaa sidoo kale aad u fiican. Heerkulka shaqada wuxuu gaari karaa ilaa 200 darajo Celsius. Waxaa intaa dheer, qaabkeedu waa mid adag, waxqabadkiisu waa mid deggan, iyo waxay leedahay wax qabad qiimo leh, sidaa darteed codsigeedu aad buu u ballaaran yahay. Laakin sababtoo ah dhaqdhaqaaqeeda kiimikada ee xooggan, waa in lagu daaweeyaa dusha sare daahan. (Sida Zn, Ni plating, electrophoresis, passivation, iwm.).

 

Ugu weyn qayb ka mid ah magnets NdFeB waa curiyaha dhulka naadirka ah neodymium. Dhulka naadir maaha loo yaqaan dhul naadir ah sababtoo ah xooga saaridiisa oo yar, laakiin way adagtahay in la sameeyo oo ka duwan alaabta kale ee ku xiran curaarta kiimikada. Inkastoo ay Soo jiidashada magnetic ee magnets ndFeB waa mid aad u xoog badan, xitaa waxaa la sheegay in Magnets NdFeB waxay nuugi kartaa 600 jeer miisaankooda. Laakiin dhab ahaantii, tani Hadalka ma aha mid dhamaystiran, sababtoo ah soo jiidashada magnetic sidoo kale waa ay saameeyeen xaalado badan sida qaabka iyo masaafada. Tusaale ahaan, loogu talagalay magnets leh dhexroor isku mid ah, oo sarreeya magnetka, ayaa sii xoogeysanaya xoogga soo jiidashada magnetic; Magnet-ka leh dhererka isku midka ah, ayaa ka weyn dhexroorka, ayaa weynaanta xoogga soo jiidashada magnetic.
