Qaybta NdFeB, guud ahaan lagu dabaqay matoorada korontada

Qaybta NdFeB, guud ahaan lagu dabaqay matoorada korantada Sawirka sifaysan

Sharaxaad Gaaban:

Qaybta Ndfeb waxaa si weyn loogu isticmaalaa matoorada iyo dhammaan noocyada qalabka.Qaadashada noocyada kala duwan ee matoorrada tusaale ahaan, isticmaalka Qaybta Ndfeb waxay leedahay faa'iidooyinka qaylada hoose iyo qulqulka sare.Darajooyinka ka sarreeya SH ee Qaybta Ndfeb waxaa inta badan lagu isticmaalaa suuqa hadda.

Darajada ka sareysa SH ee shirkadeena si weyn loo isticmaalo oo ka sareysa tignoolajiyada aan dysprosium-ka ahayn ama tignoolajiyada ka yar dysprosium faa'iidada qiimaha caanaha waa iska cadahay.

Waxaan loo habeyn karaa iyadoo loo eegayo cabbirka la cayimay macaamiisha, arc bannaan, kaas oo xalliya qashinka mashiinka billet-ka ee labajibbaaran, kharashka badan iwm. Isla mar ahaantaana, waxaanu isticmaalnaa habka dhexgalka arc ee darajada hoose ee alaabta iyada oo loo marayo sputtering magnetron, u ogolow dhulka naadirka ah si fiican- Xadka xad-dhaafka ah ee xadka hadhuudhka ee magnetka, taasoo ka dhigaysa dahaarka mid ka xasilloon habka dhexgalka suuqa ee hadda isku mar, si loo gaaro qiimo jaban macaamiisha.

Cabbirka, shirkadeena waxay ku qalabaysan tahay mashiinka kala soocida cabbirka arc ee Keyence, taas oo yaraynaysa khatarta ay keento dufcaddii xun ee xakamaynta dulqaadka qaybta magnet-ka ee macaamiisha.

Si kasta oo ay tahay nooca daahan, dhammaanteen waxaan hubin karnaa daawaynta gaarka ah ee arc dusha sare ee qaybta loogu talagalay isku xirnaanta kolloid ee magnet si xalalka habka isticmaalka halkaas oo usha, xiisadda xabagta ee ku xiran waa mid aan ku filneyn iyo wixii la mid ah.
Shuruudaha gaarsiinta, waxaan haynaa meelo banaan oo kala duwan oo cabbir iyo darajooyin kala duwan leh, si aan u samayno prototype magnet wakhti kasta.Waxaan horay u dalbannaa budada budada ah si tiknoolijiyada dual alloy-ka dabacsan ay u qanciso shuruudaha gaarsiinta macaamiisha ka dib markaan helno baahida macaamiisha.

Shirkaddayadu waxay ku qalabaysan tahay koox farsamo iyo iibka xirfadlayaasha ah kuwaas oo ku siin kara talo farsamo, nidaamka isku dhafka magnet, iyo tiro badan oo ah kiisaska isticmaalka wakhti kasta si loo hubiyo in aysan jirin welwel dheeraad ah oo ku saabsan habka loo isticmaalo macaamiisha.

Waxaan si adag u hoggaansanahay heerarka xakamaynta habka, xakamaynta socodka si waafaqsan nidaamka IATF16949, si loo hubiyo bixinta iyo kormeerka tayada macaamiisha.
