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 "nokhozo" 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 kuluhlu lobushushu obuphakathi kwe-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 kumabanga ahlukeneyo, ahambelana nokomelela kwemagnethi yawo, ukusuka ku-N35 (eyona ibuthathaka kwaye ixabisa kancinci) ukuya ku-N52 (eyona yomeleleyo, ibiza kakhulu kwaye inobuqhophololo). 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.
