Mayendedwe ndi kuumba kwa maginito apadera

maginito, wapadera woboola pakati maginito mu ndondomeko kupanga n'zovuta kuchita nthawi imodzi processing kupanga.

Maginito akuyang'ana ndi kupanga dongosolo: maginito ufa wa maginito pambuyo lolunjika, akamaumba ndi isostatic kukanikiza opangidwa opanda kanthu kachulukidwe ndi otsika kwambiri, amene ndi chinthu zoipa kupanga, akusowekapo ndipo lili pores zambiri, zosavuta adsorption wa chiwerengero chachikulu cha mpweya munali. madzi, ku njira yotsatira kubweretsa mavuto ndi zovuta.Chifukwa cha otsika kachulukidwe wa wobiriwira billet, sintering kufupikitsa mlingo ndi lalikulu, mapindikidwe losavuta, sikelo yosavuta kulolerana, choncho m'pofunika sintering, ndi ndondomeko sintering ntchito zinachitikira zofunika ndi mkulu.

M'ndondomeko ya maginito ndi kuumba, chosowekacho chiyenera kudutsa njira ziwiri chikayikidwa mu ng'anjo ya sintering:

Sintering ndi kukalamba: 

1. Sintering;Pa mkulu kutentha imeneyi kwa nthawi, zofunika sintered thupi kachulukidwe patsogolo.Kachulukidwe wachibale wakula kuchokera ku 0.6-0.7 mpaka pamwamba pa 0.95.The mkati zikuchokera aliyense njere ndi zina homogenized.Danga pakati pa tinthu tating'onoting'ono tachepa, ndipo mpweya wamadzi wa adsorbed umatulutsidwa.

2. Kukalamba:sintered NdFeb maginitobillet kachulukidwe ndi mkulu, Br ndi mkulu, koma coercivity ndi maginito mphamvu mankhwala si mkulu.Izi ndichifukwa choti gawo lolemera la neodymium silimwazika bwino.Pa kutentha kwaukalamba, gawo lolemera la neodymium limazungulira tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono.Pambuyo pa ukalamba, Br wa billet amangowonjezeredwa pang'ono, koma kukakamiza kumawirikiza kawiri.

Kuyang'ana ndi kupanga katsatidwe ka maginito pambuyo popanga zinthu zopanda kanthu kuyenera kuwunikiridwa ndikuyesedwa motere kuti zitsimikizire kuti ntchito ya maginito ndiyoyenera:

A. Maginito ntchito mayeso pambuyo kutentha sintering;

B. Kuzindikira kachulukidwe pambuyo pa kutentha kwakukulu kwa sintering;

C. Maonekedwe sikelo anayendera pambuyo kutentha sintering; 

D. Pambuyo kutentha sintering: mpweya, mpweya ndi nayitrogeni kusanthula;

E. Pambuyo kujambula demagnetization pamapindikira kudzera maginito mita kudziwa ngati akusowekapo amakhutitsidwa ndi muyezo dziko.Popeza gawo lalikulu laNdFeb maginitoamapangidwa ndi chitsulo, NdFeb mosavuta oxidized pamene poyera mpweya kapena lonyowa chilengedwe.Electroplating Permanent maginitondi njira yofunika kukongoletsa maonekedwe a maginito ndi kuwonjezera maginito kusunga nthawi.Magnet pamwamba processing makamaka nthaka, nthaka wakuda, faifi tambala, mkuwa, golide, siliva, epoxy utomoni.

Kupaka pamwamba ndi kosiyana ndi mtundu wake ndi kosiyana, nthawi yosungira si yofanana, iliyonse ili ndi ubwino ndi zovuta zake. 

1. Zinc: mawonekedwe ndi oyera asiliva, amatha kukhala maola 12 mpaka 48 amchere, amatha kulumikizidwa ndi guluu (monga guluu AB), ngati mphamvu ya electroplating ndi yabwino, imatha kusungidwa kwa zaka ziwiri kapena zisanu. , mtengo wa electroplating ndi wotsika.

2. Nickel: mawonekedwe amawoneka ngati zitsulo zosapanga dzimbiri, zomwe zimayikidwa mumlengalenga sizili zophweka kuti zikhale ndi oxidize, maonekedwe abwino, gloss wabwino, akhoza kukhala maola 12 mpaka 72 akuyesa kutsitsi mchere.Choyipa ndichakuti sikosavuta kugwiritsa ntchito guluu polumikizana, mawonekedwe amafuta opaka mafuta siwolimba, ndipo zokutira ndizosavuta kugwa.Kufulumizitsa oxidation, msika tsopano ndi faifi tambala - mkuwa - nickel plating njira kuchita 24-96 maola opopera mchere.

3. Black Zinc: malinga ndi makasitomala makonda zofuna za maginito padziko ndi kukonzedwa mu wakuda, ndi pamaziko a kanasonkhezereka mankhwala mankhwala kuwonjezera wosanjikiza wakuda kukonza filimu, filimuyi akhoza kuimba zotsatira za kukonza maginito, kuonjezera nthawi yopopera mchere.Koma mawonekedwe ake ndi osavuta kukanda, amataya kukonza kwake.

4. Black Nickel: ndi zofunikira zomwezo zakuda zinki plating, ndi pamaziko a faifi tambala plating pambuyo mankhwala mankhwala kuwonjezera wosanjikiza wakuda kukonza filimu. 

5. Golide: zomwe zimagwiritsidwa ntchito popanga zodzikongoletsera maginito Chalk, tsopano pali ambiri otchuka kwambiri maginito zokongoletsera manja. 

6. Epoxy resin: kuti muwonjezere kukana kutsekemera kwa mchere ku chinthucho, utoto wa utomoni umawonjezeredwa kunja kwa maginito pambuyo pa plating ya nickel, yomwe nthawi zambiri imakhala yakuda.Ndi zokutira zokhala ndi kukana kwa dzimbiri kunja kwa zokutira maginito.Kuzungulira kwa maginito ndikupanga dongosolo la maginito maginito, kutanthauza kuti magnetize maginito zinthu kapena kusowa kwa maginito maginito kuwonjezera maginito.Nthawi zambiri, chinthu cha maginito kuti chikhale ndi maginito chikhoza kuyikidwa mu mphamvu ya maginito yomwe imapangidwa ndi koyilo yomwe imadutsapo, ndipo mphamvu ya maginito yomwe ili mkati mwa maginito imayendetsedwa ndi mphamvu yakunja ya maginito.
