  • SmCo hlau nplaum

    Cov lus piav qhia luv luv:

    SmCo hlau nplaum sawv cev rau tiam tom kawg ntawm cov ntaub ntawv sib nqus. Lawv tau tsim ntau dua 40 xyoo dhau los thiab qhia txog cov era ntawm cov hlau nplaum ruaj khov. Lub sijhawm ntawd, cov khoom siv hlau tsis tshua muaj nqi hauv lub ntiaj teb no kim heev. Thaum xyoo 1980, SmCo cov khoom siv tau nce ntxiv los ntawm NdFeB cov hlau nplaum. Vim tias qhov nqi nce siab nyob hauv lub ntiaj teb tsis tshua muaj neodymium thiab dysprosium (Nd / Dy), cov khoom siv tam sim no tau rov qab tau txais nws cov koob meej hauv cov ntawv thov ntawm qhov kub siab dua (150 ° C - 200 ° C). Txawm li cas los xij, muaj kev txwv teeb tsa ntawm cov khoom siv hais txog qhov siab tshaj plaws. Ob qhov tseem ceeb ntawm SmCo hlau nplaum muaj, 1: 5 hom (SmCo5) thiab 2:17 hom (Sm2Co17). SmCo hlau nplaum muaj super siab sib nqus khoom thiab kub zog.

     Nco tseg:
    · Peb nyob li qub li saum toj no tshwj tsis yog sau los ntawm cov qhua tuaj noj mov. Cov ntsuas kub qhov kub thiab qhov ntsuas kub ua kom sib tshooj yog rau siv xwb, tsis yog lub hauv paus rau kev txiav txim siab.

     

    Hom tau tsam:
    Kev siv cov hlau nplaum no tau tso cai los ntawm qhov kub thiab txias hauv qhov ntau ntawm 250ºC mus rau 350ºC thiab lawv cov Curie kub yuav ua tau siab

    li 710 txog 880 ° C. Yog li no, SmCo hlau nplaum muaj qhov zoo tshaj plaws hlau nplaum ruaj khov vim yog lub zog tsis kam mus rau qhov kub thiab txias.

    SmCo hlau nplaum yog tus cwj pwm los ntawm kev tiv thaiv corrosion heev, tsis muaj txheej xav tau rau kev tiv thaiv saum npoo.

     

    Nta:
    Ib qho kev cuam tshuam ntawm SmCo hlau nplaum yog qhov cim brittleness ntawm cov khoom - qhov tseem ceeb uas yuav tsum tau tshwj xeeb rau hauv kev txiav txim siab thaum ua.

    Cov hlau nplaum yog galvanized lossis coated los ntawm cathodic electrodeposition rau qee yam kev siv.

     

    Daim ntawv thov:
    Hauv thaj chaw muaj kev ua haujlwm kub, kev tiv thaiv corrosion thiab oxidation tsis kam yog qhov tseem ceeb heev. Xws li, hluav taws xob hauv tshuab hluav taws xob,Hlau nplaumkis ic,

    Kev kho mob sib nqus, Magnistor, thiab lwm yam.

    Txhua qhov tau tshaj tawm tau txiav txim siab siv tus qauv coj mus kuaj raws li IEC 60404-5. Cov lus qhia tshwj xeeb hauv qab no yog cov nqe lus qhia qhov tseem ceeb thiab

    txawv. Lub max. kev khiav hauj lwm kub yog nyob ntawm cov hlau nplaum dimesion thiab cov ntawv thov tshwj xeeb. Xav paub ntau ntxiv thov hu rau peb

    daim ntawv thov engineers.
