  • Umazibuthe weFerrite

    Inkcazo emfutshane:

    Ii-ferrites ezinzima ezisekwe kwi-barium ferrite kunye ne-strontium powders (ifomula yeekhemikhali i-BaO • 6Fe2O3 kunye ne-SrO • 6Fe2O3) eyenziwe. Ziqukethe isinyithi esineoksijini, ke ngoko zibandakanyiwe kwiqela lezinto zeceramic. Ziqulethe i-approx. I-90% ye-oxide yentsimbi (i-Fe2O3) kunye ne-10% ye-alkaline yomhlaba oxide (i-BaO okanye i-SrO) -izinto ezingafunekiyo ezininzi kwaye ezingabizi kakhulu. Zahlulahlulahlulahlula zibe zi-isotropic kunye ne-anisotropic, amasuntswana okugqibela alungelelaniswe kwelinye
    ulwalathiso olufumana iimpawu ezingcono zemagneti. Iimagnethi ze-Isotropic zenziwe ngokucinezela ngelixa oomazibuthe be-anisotropic becinezelwe ngaphakathi kumazibuthe. Oku kubonelela ngemagnethi ngendlela ekhethekileyo kwaye iphindaphindwe kathathu ukuxinana kwamandla.

     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:

    Njengoko kuqhelekile kwiiceramics ze-oxide, iimagnethi ezilukhuni ze-ferrite zibonisa isimilo esinganyangekiyo kufuma, izinyibilikisi, izisombululo zealkali,

    iiasidi ezibuthathaka, iityiwa, izinto zokuthambisa kunye nezinto ezingcolisa igesi. Ngokubanzi, iimagnethi ezinzima ze-ferrite zinokusetyenziswa ngaphandle kokhuselo lokongezwa komhlwa.
    Phawu:
    Ngenxa yobunzima babo obukhulu (i-6-7 Mohs), iimagnethi zeFerrite zibukhali kwaye zibuthathaka ekunkqonkqozeni nasekuguqulweni. Ngexesha lokulungiswa, kufuneka zenziwe ngomatshini ngezixhobo zedayimani. Amaqondo obushushu asebenzayo ngoomazibuthe be-ferrite ngokubanzi aphakathi kwe-40ºC kunye ne-250ºC.

    Isicelo:

    Iimo ezahlukeneyo zisetyenziswa kubunjineli bezithuthi, ezinje nge-automation kunye nolawulo lwemilinganiselo. Ezinye izinto ezinje ngeMoto yombane yoomatshini (izisuli, isitulo esihleliyo semoto), Ukufundisa, ukufunxa umnyango, ibhayisekile Magnetic kunye nosihlalo wokuthambisa, njl.

     

    Namhlanje, ii-ferrites ezinzima zimela elona nani likhulu loomazibuthe abasisigxina abavelisiweyo. Ngokuchasene neemagnethi zeAlNiCo, ii-ferrites ezinzima zibonakaliswa kukuxinana kokuhamba kodwa amandla endawo anyanzelekileyo. Oku kubangela imilo ethe tyaba yemathiriyeli. I-Barium ferrite kunye ne-strontium ferrite yahlulwe ngokuxhomekeke kwinto yokuqala.

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