  • Umazibuthe weSmCo

    Inkcazo emfutshane:

    Iimagnethi zeSmCo zimele ukuveliswa kwezinto zemagneti zakutshanje. Ziyaphuhliswa ngaphezulu kweminyaka engama-40 eyadlulayo kwaye zazisa ixesha leemagnethi ezisisigxina. Ngelo xesha, ezi zinto zinqabileyo zomhlaba zazibiza kakhulu. Ngexesha lama-1980, izinto zeSmCo zazisiya zitshintshwa ngoomazibuthe beNdFeB. Ngenxa yokunyuka kwamaxabiso amakhulu kumhlaba onqabileyo we-neodymium kunye ne-dysprosium (Nd / Dy), le nto ngoku ibuye yathandwa kwizicelo kumaqondo obushushu aphezulu (150 ° C - 200 ° C). Nangona kunjalo, kukho imida emiselweyo kwimathiriyeli ngokubhekisele kwisona siphumo siphezulu. Iindidi ezimbini ezinkulu iimagnethi SmCo ziyafumaneka, 1: 5 uhlobo (SmCo5) kunye nohlobo 2:17 (Sm2Co17). Iimagnethi zeSmCo zineempawu eziphezulu kakhulu zemagnethi kunye neepropathi zobushushu.

     Phawula:
    · Sihlala sifana nangasentla ngaphandle kokuba kuchaziwe kumthengi. Iqondo lobushushu le-Curie kunye nobushushu bokulinganisa ziireferensi kuphela, hayi njengesiseko sesigqibo. Ubushushu obuphezulu bokusebenza kwemagnethi buyatshintsha ngenxa yomyinge wobude kunye nobubanzi kunye nemeko yokusingqongileyo.

     

    Uncedo:
    Ukusetyenziswa kwala magnethi kulungiswe ngamaqondo obushushu kuluhlu olubanzi olubaleka ukusuka kuma-250ºC ukuya kuma-350ºC kwaye ubushushu bawo beCurie bunokuphakama

    njengoko 710 ukuba 880 ° C. Ke ngoko, umazibuthe weSmCo unokuqina okuzinzileyo ngenxa yokuxhathisa okuphezulu kubushushu obuphezulu.

    Iimagnethi SmCo luphawulwa nokumelana eliphezulu kakhulu, akukho ukutyabeka efunekayo ukuze ukhuseleko komhlaba.

     

    Phawu:
    Ukungancedi koomazibuthe beSmCo kukukrala okuphathekayo kwemathiriyeli - into ekufuneka ithathelwe ingqalelo ngokukodwa ngexesha lokulungiswa.

    Iimagnethi zenziwe zaza zagqunywa okanye zagutyungelwa ngumbane wobuchwephesha kwizicelo ezithile.

     

    Isicelo:
    Kwiindawo ezinobushushu obuphezulu bokusebenza, ukubola okukhulu kunye nokumelana ne-oxidation kubalulekile. Ezifana, i-magnetron ye-elektroniki,ImagnethiUkuhambisa ic,

    Unyango Magnetic, Magnistor, njl

    Onke amaxabiso achaziweyo amiselwa kusetyenziswa iisampulu ezisemgangathweni ngokwe-IEC 60404-5. Ezi nkcukacha zilandelayo zisebenza njengexabiso lesalathiso kwaye zinokwenzeka

    yahlukile. Ubuninzi. lobushushu yokusebenza kuxhomekeke dimesion umazibuthe kunye isicelo esithile. Ngolwazi oluthe kratya nceda unxibelelane nathi

    iinjineli zesicelo.
