Ubwino wa zokutira maginito mwachindunji umatsimikizira moyo wautumiki wa mankhwala

Xinfeng anayesera anasonyeza kuti kiyubiki centimita waSintered NdFeb MagnetIkhoza kuipitsidwa ndi okosijeni pambuyo poyatsidwa ndi mpweya pa 150 ℃ kwa masiku 51.Imawononga mosavuta munjira zofooka za asidi.Kuti apange NdFeb Permanent Magnet kukhala yolimba, imayenera kukhala ndi zaka 20-30 za moyo wautumiki, iyenera kuchitidwa ndi mankhwala owononga pamwamba, kuti zisawonongeke zowonongeka kwa maginito.Ndipo kawirikawiri amatchedwaElectroplating Permanent Magnet.

Pakali pano, sintered NdFeb okhazikika maginito dongosolo kupanga makampani ambiri utenga electroplating zitsulo, electroplating + mankhwala golide plating, electrophoretic ❖ kuyanika ndi phosphating mankhwala, etc., padziko maginito wokutidwa ndi wosanjikiza zina wa odzipatula, ndi maginito pamwamba ndi sing'anga zowononga zimalekanitsidwa, pofuna kupewa kuwonongeka kwa sing'anga mpaka maginito.

1.Kawirikawiri kanasonkhezereka, faifi tambala + mkuwa + faifi tambala, faifi tambala + mkuwa + electroless faifi tambala plating njira zitatu, zina zitsulo plating zofunika, zambiri mu nickel plating ndiyeno zitsulo plating.

2.Muzochitika zina zapadera zidzagwiritsanso ntchito phosphating1) Mu NdFeb maginito mankhwala chifukwa cha zolowa, kusunga nthawi yaitali kwambiri ndi zosamveka kutsatira pamwamba mankhwala njira, ntchito phosphating yosavuta ndi yosavuta;(2) Pamene maginito amafuna epoxy zomatira, utoto, zomatira, utoto ndi ena epoxy organic chomangira mphamvu amafuna gawo lapansi kukhala ndi ntchito yabwino kuloŵa.Njira ya Phosphating imatha kupititsa patsogolo luso lolowetsa maginito.

3.Kupaka kwa Electrophoretic kwakhala imodzi mwa njira zogwiritsira ntchito zowonongeka zowonongeka pamwamba.Chifukwa sikuti imakhala ndi mphamvu yabwino yolumikizirana ndi maginito a porous, komanso imakhala ndi kukana kwa dzimbiri kutsitsi mchere, asidi ndi zamchere, ndi zina zambiri, kukana kwa dzimbiri.Koma kuyerekeza ndi zokutira zopopera, kukana kwake kutentha ndi chinyezi ndikochepa.

Makasitomala amatha kusankha ❖ kuyanika molingana ndi zomwe akufuna kuchita.Ndi kukula kwa ntchito galimoto, makasitomala ndi zofunika apamwamba NdFeb dzimbiri kukana, ndiHigh Quality Electroplating Permanent Magnetchofunika.The HAST kuyesera (PCT kuyesera) lakonzedwa kuyesa kukana dzimbiri wa sintered NdFeb maginito okhazikika mu yonyowa ndi kutentha kwambiri mapangidwe.

Kodi makasitomala amazindikira bwanji ngati zokutira zikukwaniritsa zofunikira?Salt kutsitsi kuyesera ndi cholinga cha pamwamba pa odana ndi dzimbiri ❖ kuyanika ankachitira sintered NdFeb maginito kuchita mwamsanga odana dzimbiri kuyesera, pa mapeto a kuyesera, chitsanzo ku bokosi mayeso, youma, ndi maso kapena kukulitsa galasi kuti. kuona chitsanzo pamwamba ndi mawanga, mawanga kukula kwa bokosi kusintha mtundu.

Kuti tifotokoze mwachidule, pongomvetsetsa momwe zinthu zimapangidwira komanso zofunikira za chinthucho, kasitomala amatha kuweruza molondola kugwirizana kwa chinthucho.Mwachidule, ndikumvetsetsa kwa magwiridwe antchito, kuwongolera kulolerana kwa mawonekedwe, kuzindikira kwa zokutira komanso kuwunika kwa mawonekedwe.

Pankhani ya magwiridwe antchito, Br (maginito otsalira), Hcb (kukakamiza), Hcj (kukakamiza kwamkati), (BH) Max (maximum maginito mphamvu mankhwala) ndi demagnetization pamapindikira amatha kuzindikirika ndi magwiridwe antchito.Dimensional kulolerana, kulondola kungayesedwe ndi vernier calipers;Pa zokutira, mtundu ndi kuwala kwa zokutira kumatha kuwonedwa ndi maso amaliseche ndikuzindikiridwa ndi mphamvu yomangirira ndi mayeso opopera mchere.Maonekedwe athunthu, makamaka ndi diso lamaliseche kapena galasi lokulitsa, kapena maikulosikopu ya kuwala (kwa mzere wa mankhwala osakwana 0.2mm), pamwamba pa maginito ndi osalala, palibe tinthu tating'onoting'ono ndi matupi akunja, palibe mawanga, palibe kugwa m'mphepete mwake, mawonekedwe ndi oyenera.
