Anisotropic Sintered NdFeB NIB Ring Permanent Magnet

Sintered NIB Magnets
Imagnethi ye-NIB ye-Sintered inamandla aphezulu kodwa ilinganiselwe kwiijometri ezilula kwaye zinokuba brittle. Zenziwa ngoxinzelelo zenza izinto eziluhlaza zibe ziibhloko, ezithi ke zihambe ngenkqubo yokufudumala enzima. Ibhloko iyasikwa ukuze imile kwaye igqunywe ukuthintela ukubola. Imagnethi ene-Sintered idla ngokuba yi-anisotropic, nto leyo ethetha ukuba banokukhetha kwicala lemagnethi yabo. Ukwenza imagnethi yemagnethi ngokuchasene "nezikhozo" kuya kunciphisa amandla emagnethi ukuya kuthi ga kwi-50%.

I-Demagnetization
Imagnethi ye-NIB ngokwenene ziimagnethi ezisisigxina, njengoko ziphulukana ne-thein umazibuthe, okanye i-degauss ngokwendalo, malunga ne-1% ngenkulungwane. Zisebenza ngokubanzi phakathi koluhlu lobushushu obuyi-215°Fto 176°F(-138°C ukuya kuma-80°℃). Kwizicelo ezifuna uluhlu olubanzi lobushushu, iimagnethi zeSamarium Cobalt (SmCo) zisetyenziswa.

Iingubo
Ngenxa yokuba i-NIB engafakwanga i-sintered iya kugqwala kwaye idilike ngenxa yokuvezwa kwi-atmosfera, zithengiswa ngengubo ekhuselayo. Eyona nto ixhaphakileyo yenziwe nge-nickel, nangona ezinye iingubo ezithengiswayo zibonelela ngokumelana nokushisa okuphezulu, ukufuma okuphezulu, ukutshiza ityuwa, i-solvents kunye neegesi.

IBanga
Imagnethi ye-NIB iza kumabakala ahlukeneyo, ahambelana nokomelela kwemagnethi yawo, ukusuka ku-N35 (eyona ibuthathaka kwaye inexabiso eliphantsi) ukuya ku-N52 (eyona inamandla, ibiza kakhulu kwaye inobunkunkqele obungaphezulu). 52/35 = 1.49). Kuthi, kuqhelekile ukufumana imagnethi yebakala labathengi kuluhlu lwe-N40 ukuya ku-N42. Kwimveliso yevolumu, i-N35 ihlala isetyenziswa ifsize kwaye ubunzima ayisiyonto iqwalaselwayo kakhulu njengoko kubiza kancinci. f ubukhulu kunye nobunzima zizinto ezibalulekileyo, amabakala aphezulu aqhele ukusetyenziswa. Kukho iprimiyamu kwixabiso lemagnethi yodidi oluphezulu ngoko kuqhelekile ukubona imagnethi i-N48 kunye ne-N50 esetyenziswa kwimveliso xa ithelekiswa ne-N52.
