Maginito a Neodymium amapangidwa ndi zinthu zamphamvu za Nd-Fe-B zosakanikirana ndi epoxy binder.Kusakaniza kuli pafupifupi 97 vol% maginito zakuthupi ku 3 vol% epoxy.Kupanga kumaphatikizapo kuphatikiza ufa wa Nd-Fe-B ndi binder epoxy ndi kukanikiza kusakaniza mu makina osindikizira ndikuchiritsa gawolo mu uvuni.Popeza zakuthupi aumbike ndi psinjika yomangira, miyeso amangosiyana .002″ kapena bwino kwa anapatsidwa run.The Bonded psinjika Anaumba NdFeB maginito chimagwiritsidwa ntchito mosavuta nkhungu ndi mkulu maginito katundu, khola ntchito kutentha, zabwino dzimbiri-kukana.Amatha kuyika nkhungu ndi ziwalo zina.
Kuphatikiza wathunthu wa jekeseni ndondomeko ndi mkulu-katundu osowa-pansi ufa kumapangitsa kukhala kotheka kupanga mosavuta amphamvu womangidwa Ndfeb mphete maginito kwa wokamba.Maginito a Bonded Neodymium ali ndi mwayi wamawonekedwe apamwamba kwambiri poyerekeza ndi maginito a Sintered.Maginito ayenera yokutidwa ndi wosanjikiza wakuda kapena imvi epoxy kapena Parylene kuwateteza ku dzimbiri.
The Hot- mbamuidwa NdFeB maginito ogaŵikana mitundu iwiri, Hot mbamuikha isotropic NdFeB (MQ 2) ndi otentha-extruded anisotropic NdFeb maginito (MQ 3) .The Hot- mbamuikha isotropic NdFeb maginito amapangidwa ndi mofulumira kuzimitsidwa NdFeB maginito pw der pansi kutentha kudzera compression.The otentha- mbamuidwa anisotropic NdFeB maginito makamaka anisotropic radially-oriented mphete maginito amene amapangidwa kudzera psinjika ndi extrusion mapindikidwe ndi mofulumira kuzimitsidwa NdFeB maginito ufa pansi kutentha.Mwamakonda jekeseni Bonded NdFeB mphete maginito.
Maginito a neodymium-iron-boron (NdFeB) ndi maginito amphamvu omwe amagwiritsidwa ntchito pazinthu zosiyanasiyana.Epoxy ❖ kuyanika nthawi zambiri amagwiritsidwa ntchito pomanga maginito a NdFeB;Electroless nickel plating imagwiritsidwanso ntchito kupewa dzimbiri.Isotropic womangidwa NdFeB zakuthupi akhoza magnetized mbali iliyonse, kapena mizati angapo.
Bonded Nd-Fe-B zakuthupi ndi isotropic, kotero zimatha kupangidwa ndi maginito kudzera mbali iliyonse, kuphatikiza makonzedwe amitundu yambiri.Chifukwa zinthuzo zili mu epoxy binder, zimatha kupangidwa ndi mphero kapena lathe.Komabe, zinthuzo sizingagwirizane ndi ulusi, choncho mabowo sangagwire.Zida za Bonded Nd-Fe-B nthawi zambiri zimagwiritsidwa ntchito kuchepetsa kukula kwa mapangidwe omwe amagwiritsa ntchito zida za maginito za ceramic.Kuchepetsa kwakukulu kungatheke chifukwa zinthuzo zimakhala zamphamvu pafupifupi katatu kuposa za ceramic maginito.Kuphatikiza apo, popeza zinthuzo ndi isotropic, zimatha kukhala ndi maginito amitundu yambiri, monga mawonekedwe a NSNS pamtunda wakunja wa mphete.
Zomangira NdFeB maginito ndi remanence mkulu, coercivity mkulu, mankhwala mkulu mphamvu, ntchito mkulu ndi chiŵerengero cha mtengo, zosavuta pokonza makulidwe osiyanasiyana, ndi specifications osachepera advantage.They akhoza kukhala kwa medina unit pamodzi ndi zigawo zina, chimagwiritsidwa ntchito nthawi yochepa, yaing'ono. , zopepuka, ndi zoonda zamagetsi zamagetsi.
Maginito omangidwa a NdFeb ndi mphamvu yamaginito apamwamba kuposa maginito opangidwa ndi jekeseni, alinso ndi mwayi wamawonekedwe apamwamba kwambiri poyerekeza ndi maginito a sintered.Kukakamiza kwakukulu, mankhwala amphamvu kwambiri, kukana dzimbiri, komanso kukana kutentha.
Bonded neodymium ufa amagwiritsidwa ntchito popanga maginito awa.Ufa umasungunuka ndikusakaniza ndi polima.Zigawo zimapanikizidwa kapena kutulutsidwa kuti apange chinthucho.Maginito a Neodymium omangidwa amatha kupangidwa ndi maginito kukhala mapatani ovuta okhala ndi mitengo ingapo.Ngakhale ndizofooka kwambiri kuposa maginito a Sintered Neodymium, maginito a Bonded neodymium amapereka kusinthasintha kwakukulu malinga ndi mawonekedwe omwe angapangidwe.Amakhalanso opepuka kuposa Samarium Cobalt, ndipo amakhala ndi kutentha kochepa kovomerezeka (kukakamiza).Komabe, amapereka mtengo wabwino kwambiri pamapulogalamu omwe amafunikira maginito ang'onoang'ono kapena kugwiritsa ntchito mphete zowunikira.

Kutentha Kwambiri Kwambiri:
Ngakhale Curie kutentha kwa NdFeB zakuthupi ndi za 310 ºC kwa 0% cobalt zakuthupi wamkulu kuposa 370 ºC kwa 5% kobalt, ena imfa yosasinthika wa linanena bungwe angayembekezere ngakhale zolimbitsa kutentha.Maginito a Neo alinso ndi Reversible Temperature Coefficient of Induction yomwe imachepetsa mphamvu ya maginito pamene kutentha kumakwera.Kusankhidwa kwa neo maginito m'malo SmCo, ndi ntchito ya kutentha pazipita ntchito, chofunika maginito linanena bungwe pa mmene kutentha ntchito ndi okwana mtengo wa dongosolo.
Neo maginito alinso ndi zolepheretsa chifukwa cha khalidwe lawo la dzimbiri.Munyengo yachinyontho, zokutira zodzitchinjiriza kapena zokutira zimalimbikitsidwa kwambiri.Zopaka zomwe zagwiritsidwa ntchito bwino zikuphatikizapo;e-coating, zokutira ufa, nickel plating, zinki plating, parylene ndi kuphatikiza kwa zokutira izi.
