Cob phum Magnets lub ntsiab lus tseem ceeb
Sintered ferrite
Sintered Ferrite (Sintered Ferrite) cov ntaub ntawv tseem ceeb, xws li BaFe12019 thiab SrFe12019, raws li qhov sib txawv ntawm cov hlau nplaum sib nqus uas tau muab faib ua cov hlau isotropic thiab heterogeneous.
Vim tias nws tsis muaj nqi thiab ntau qhov chaw sib nqus thiab ua qhov dav siv ntau lub nplhaib. Ferrite cov hlau nplaum yog tsim los ntawm cov tshuab xuab zeb, cov kev ntxhib los mos kuj yog ib qho nyuaj, tab sis kuj yog ib qho khoom siv, vim tias cov hlau nplaum ferrite muaj cua kub thiab tsis tshua muaj nqi, tau los ua ib txwm siv hlau nplaum.
Sib nqus hlau nplaum
Roj Hmab Sib Tshooj (Rubber Magnet) yog cov khoom ferrite, los ntawm cov ferrite hmoov thiab cov khoom hluav taws xob hluavtaws los ntawm extrusion, dov molding, kev txhaj molding thiab lwm cov txheej txheem ua ntawm muag, Elastic thiab twisted magnets. Yuav tuaj yeem ua tiav rau hauv txawb, dov, ntawv thiab ntau hom duab. Roj teeb hlau nplaum los ntawm cov hmoov hlau nplaum (SrO6Fe2O3), polyethylene (CPE) thiab lwm yam khoom siv (EBSO, DOP) thiab lwm yam khoom, los ntawm extrusion, dov ntawm. Roj hmab cords yuav yog hom qe los yog heterosexual, ua los ntawm ferrite, CPE thiab tej yam kab kawm, bendable, twistable thiab rollable. Nws tsis xav tau kev kho dua tshiab, yuav tsum yog qhov loj me me ntawm txoj kev kho, rubber hlau nplaum kuj tuaj yeem ua raws li tus neeg yuav tsum PVC, Beijiao, UV roj. Nws cov khoom sib nqus zog yog nruab nrab ntawm 0.60 thiab 1.50 Mgoe. Daim ntawv thov ntawm cov khoom siv roj hmab thiab cov khoom sib nqus: cov tub yees, cov khoom siv xov xwm, cov khoom siv rau cov hlau thiab cov khoom sib txuas, cov khoom ua si, cov khoom siv qhia, keyboards thiab sensors ntawm daim disk. Feem ntau siv me me lub cev muaj zog, cov tub yees, cov tshuaj tua kab mob, cov khoom ua si, cov khoom ua si, ntawv sau, thiab lwm yam lag luam.
Alnico
AlNiCo (AlNiCo) yog thawj qhov tsim cov khoom siv hlau nplaum, uas yog txhuas, nickel, cobalt, hlau thiab lwm yam kab uas muaj kev sib thooj. Raws li cov txheej txheem ntau lawm muab faib ua sintered aluminium nickel cobalt (Sintered AlNiCo) thiab nrum txhuas nickel cobalt (cam khwb cia AlNiCo). Cov khoom siv yog feem ntau puag ncig thiab square. Cov khoom sintered yog siv rau ib qho me me loj, thiab cov kab mob uas ua rau lub plhom tswm xeeb yog ua tau zoo dua cov khoom tsim khoom, thiab cov khoom sib nqus cov khoom me me tsawg dua cov khoom tsim khoom, tab sis cov khoom sintered yog siv rau ib qho me me. Kev ua zoo dua. Nyob rau hauv cov khoom siv hlau nplaum tas li, nruas txhuas nickel cobalt tas nrho cov hlau nplaum muaj qhov ntxim siab ntxim siab thim rov qab, qhov kub ua haujlwm ua tau siab li 600 ℃ los yog ntau dua. Alnico cov khoom ntiag tug ntawm cov khoom siv tas li yog siv ntau yam twj paj nruag thiab lwm yam kev siv.
Samarium cobalt
SmCo (SmCo) muab faib ua SmCo5 thiab Sm2Co17 raws li qhov sib txawv hauv paus, feem ntau, rau thawj lub cim thiab ob tiam neeg tsis tshua muaj lub ntiaj teb zoo li cov khoom magnet. Vim nws cov ntaub ntawv raw yog scarce, kim thiab ua nws txoj kev loj hlob yog tsawg. SmCo raws li ib tiam thib ob lub ntiaj teb tsis tshua muaj hlau nplaum, tsis tsuas yog muaj lub siab zog khoom (14-28MGOe) thiab txhim khu kev qha coercivity, tab sis kuj nyob rau hauv lub ntiaj teb tsis tshua muaj hlau nplhaib los qhia cov yam ntxwv kub zoo. Muab piv rau NdFeB, SmCo yog qhov tsim nyog rau kev ua haujlwm hauv chaw siab kub siab (> 200 ℃).
daim ntawv thov
Kev ruaj khov hlau nplaum tau siv hauv qhuav hluav taws xob, hluav taws xob, mechanical, kev thauj mus los, kev kho mob thiab txhua yam khoom siv, thiab lwm yam kev lag luam. Xws li cov lus nrov nrov, lub xov tooj txais tog xa tuaj; sib nqus qhov system ntawm hlau nplaum; generators, hlau nplaum tas li; tshuab kev lag luam uas siv cov tshuab txuas rau sab nrauv (xws li nto sib tsoo tshuab nplaum hlau nplaum, thiab lwm yam) thiab sib nqus levitation system, hlau nplaum sib nqus sib nqus sib nqus sib nqus, sib nqus vaj huam sib luag, nqus dej cav, magnetron, proton accelerator magnetic system.
