Zeziphi iintlobo ezahlukeneyo zeemagnethi ze-NdFeB?

Imagnethi ye-NdFeB, ekwabizwa ngokuba yimagnethi ye-neodymium, ziimagnethi ezisisigxina ezenziwe ngealloyi ye-neodymium, intsimbi kunye neboron.Ezaziwa ngeempawu zazo eziqinileyo zemagneti, ezi magnethi zisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya i-elektroniki, izithuthi kunye namandla avuselelekayo.Kukho iintlobo ezahlukeneyo zeemagnethi zeNdFeB, kubandakanyaimagnethi edityanisiweyo yeNdFeBkwayeiimagnethi ze-sintered neodymium.

Iimagnethi ze-Sintered neodymiumzezona ntlobo zixhaphakileyo zeemagnethi ze-NdFeB.Zenziwa ngenkqubo ebizwa ngokuba yi-sintering, apho imathiriyeli ekrwada inyibilikiswa eziko ize ipholiswe yenze into eqinileyo.Iimagnethi ezisisiphumo zinamandla entsimi aphezulu kwaye zinokusetyenziswa kwizicelo ezifuna umhlaba owomeleleyo wemagnethi, onje ngeenjini zombane, iijenereyitha kunye nezahluli zemagnethi.

Iimagnethi zeNdFeB ezidityanisiweyo, kwelinye icala, zenziwe ngokuxuba umgubo we-NdFeB kunye ne-polymer binder kwaye emva koko ucinezele umxube kwimilo oyifunayo.Inkqubo inokuvelisa iimagnethi ezinemilo entsonkothileyo kunye nobukhulu, zibenze zilungele uluhlu olubanzi lwezicelo.Iimagnethi zeNdFeB ezidityanisiweyozisetyenziswa ngokuqhelekileyo kumashishini apho ukuguquguquka koyilo kunye nokusebenza kakuhle kweendleko kubalulekile, njengezinzwa, ii-actuator kunye namacandelo magnetic.

Zombini iimagnethi ze-sintered neodymium kunye neemagnethi ezidityanisiweyo ze-neodymium zinezibonelelo zazo kunye nokungalunganga.Iimagnethi ze-Sintered neodymium ziyaziwa ngamandla azo aphezulu wemagnethi kunye nokuxhathisa kwi-demagnetization, zizenza zilungele usetyenziso olufunayo.Nangona kunjalo, zikwabhityile kwaye zichaphazeleka kukubola, zifuna iingubo ezikhethekileyo zokuzikhusela kwizinto ezisingqongileyo.

Ngathi

Iimagnethi zeNdFeB ezidityanisiweyo, kwelinye icala, zibhetyebhetye ngakumbi kuyilo kwaye zinokuveliswa kwimiqulu ephezulu ngexabiso eliphantsi.Bakwanayo nokumelana nomhlwa okungcono kwaye ingasetyenziswa kwizicelo aphoiimagnethi ze-sintered neodymiumisenokungafaneleki.Nangona kunjalo, amandla abo emagnethi asezantsi xa kuthelekiswa neemagnethi ze-sintered neodymium kwaye zisenokungalungeli usetyenziso olusebenza kakhulu.

Isishwankathelo, iimagnethi ze-NdFeB ezidityanisiweyo kunye neemagnethi ezidityanisiweyo ze-NdFeB ziindidi ezimbini ezahlukeneyo zeemagnethi ze-NdFeB, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa.Iimagnethi ze-Sintered neodymium ziyaziwa ngamandla azo aphezulu ngumagnethi kunye nokuchasana nokukhutshwa kwemagnethi, okubenza bafanelekele izicelo ezibango, ngelixa.imagnethi edityanisiweyo yeNdFeBunikeze ukuguquguquka koyilo kunye nokusebenza kakuhle kweendleko.Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeemagnethi ze-NdFeB kubalulekile ekukhetheni umazibuthe ofanelekileyo kwisicelo esithile.
