Bonded NdFeB Magnets
Bonded NdFeB, tsim los ntawm Nd2Fe14B, yog cov hlau nplaum hluavtaws.Bonded NdFeB hlau nplaum yog cov hlau nplaum ua los ntawm "nias molding" los yog "txhaj tshuaj molding" los ntawm kev sib tov ceev-quenched NdFeB magnetic hmoov thiab binder.Bonded hlau nplaum muaj qhov raug siab qhov tseeb, tuaj yeem ua rau hauv cov khoom sib nqus nrog cov duab sib txawv, thiab muaj cov yam ntxwv ntawm kev molding ib zaug thiab ntau tus ncej.Bonded NdFeB muaj lub zog txhua yam, thiab tuaj yeem tsim tau ib zaug nrog lwm cov khoom txhawb nqa.
Bonded hlau nplaum tau tshwm sim nyob ib ncig ntawm 1970s thaum SmCo tau ua lag luam.Qhov teeb meem kev lag luam ntawm sintered mus tas li hlau nplaum yog qhov zoo heev, tab sis nws yog ib qho nyuaj rau precisely txheej txheem rau hauv cov duab tshwj xeeb, thiab lawv muaj feem xyuam rau tawg, puas, ntug poob, ces kaum poob thiab lwm yam teeb meem thaum lub sij hawm ua.Tsis tas li ntawd, lawv tsis yooj yim rau kev sib sau ua ke, yog li lawv daim ntawv thov raug txwv.Yuav kom daws tau qhov teeb meem no, cov hlau nplaum tas mus li yog pulverized, tov nrog yas, thiab nias rau hauv magnetic teb, uas yog tej zaum cov txheej txheem tsim khoom qub tshaj plaws ntawm cov hlau nplaum sib txuas.Bonded NdFeB hlau nplaum tau siv dav vim lawv cov nqi qis, qhov tseeb qhov tseeb, kev ywj pheej loj ntawm cov duab, zoo txhua yam muaj zog, thiab lub teeb tshwj xeeb lub ntiajteb txawj nqus, nrog rau kev loj hlob txhua xyoo ntawm 35%.Txij li thaum qhov tshwm sim ntawm NdFeB cov hlau nplaum ruaj khov hmoov, cov hlau nplaum hloov tau yooj yim tau ua tiav sai vim nws cov khoom sib nqus siab.
