Magnet, yakakosha-yakaita magineti mukuita kwekugadzira kwakaoma kuita imwe-nguva yekugadzirisa kuumba.
Magnet kutaridzika uye kurongeka kwekugadzira: iyo magineti poda yegineti mushure mekumisikidza, kuumba uye isostatic kudzvanya yakagadzirwa isina density yakadzikira, inova chinhu chisina kunaka mukugadzirwa, isina chinhu uye ine mamwe pores, nyore adsorption yehuwandu hukuru hwegasi rine. mvura, kune imwe nzira yekuunza dambudziko nematambudziko.Nekuda kweiyo yakaderera density yegirinhi billet, sintering yekupfupisa mwero yakakura, yakapusa deformation, chiyero chakareruka kubva mukushivirira, saka zvinodikanwa kuti sintering, uye maitiro ekuita sintering oparesheni yezvinodiwa zvakakwirira.
Mukutevedzana kwekuita magineti uye kuumbwa, iyo isina chinhu inoda kupfuura nematanho maviri kana yaiswa muchoto chekupisa:
Sintering uye kuchembera:
1. Sintering;Panguva yekushisa kwepamusoro kwenguva yenguva, iyo yakakosha sintered body density inofambira mberi.Hukama density yakawedzera kubva 0.6-0.7 kusvika pamusoro 0.95.Kuumbwa kwemukati kwezviyo chimwe nechimwe kunowedzerwa homogenized.Nzvimbo iri pakati pezvimedu inoderedzwa, uye adsorbed mhute yemvura inodzingwa.
2. Kuchembera:sintered NdFeb maginetibillet density yakakwira, Br yakakwirira, asi kumanikidza uye magineti simba chigadzirwa hachina kukwirira.Izvi zvinodaro nekuti iyo neodymium-yakapfuma chikamu haina kuparadzirwa zvakanaka.Pakuchembera tembiricha, iyo neodymium-yakapfuma chikamu chakatetepa chinokomberedza chikamu chikuru zvidimbu uye chinozvitsaura kubva kune chimwe nechimwe, zvichigadzira yakasarudzika dhizaini inokonzeresa kumanikidza kwakanyanya.Mushure mekukwegura, Br yebillet inongowedzerwa zvishoma, asi kumanikidzirwa kunowedzera kaviri.
Maonero uye kugadzira kutevedzana kwemagineti mushure mekunyudza zvigadzirwa zvisina chinhu zvinoda kuongororwa uye kuyedzwa sezvinotevera kuti ive nechokwadi chekuti basa remagineti rinokodzera:
A. Magnetic basa bvunzo pashure tembiricha sintering;
B. Density yekuona mushure mekushisa kwepamusoro sintering;
C. Chitarisiko chechiyero chekuongorora mushure mekushisa kwepamusoro sintering;
D. Mushure mekupisa kwekushisa kwepamusoro: carbon, oxygen uye nitrogen kuongorora;
E. Mushure mekudhirowa demagnetization curve kuburikidza nemagineti mita kuona kana blank inogutsikana nenyika chiyero.Sezvo chikamu chikuru cheNdFeb maginetiyakagadzirwa nesimbi, NdFeb inonyoreswa nyore nyore kana yaiswa kumhepo kana mhepo yakanyorova.Electroplating Permanent maginetiinzira yakakosha yekushongedza kutaridzika kwemagineti uye kuwedzera magineti kuchengetedza nguva.Magnet pamusoro pekugadzirisa kunyanya zingi, dema zingi, nickel, mhangura, goridhe, sirivheri, epoxy resin.
Surface plating yakasiyana nemuvara wayo wakasiyana, nguva yekuchengetedza haina kufanana, imwe neimwe ine zvakanakira nekuipira.
1. Zinc: chitarisiko chichena chesirivha, chinogona kuva 12 kusvika kumaawa 48 emunyu wekupfapfaidza, inogona kusungirirwa neimwe glue kushandiswa (zvakadai seAB glue), kana electroplating effect yakanaka, inogona kuchengetwa kwemakore maviri kusvika mashanu. , electroplating cost yakaderera.
2. Nickel: chitarisiko chinoratidzika sesimbi isina tsvina ruvara, yakaiswa mumhepo chitarisiko haisi nyore kuoxidize, kutaridzika kwakanaka, gloss yakanaka, inogona kuva maawa gumi nemaviri kusvika ku72 ekuyedza munyu pfapfaidzo.Izvo zvisingabatsiri ndezvokuti hazvisi nyore kushandisa glue yekubatanidza, kutaridzika kwekuzora kunamatira hakuna kusimba, uye kupfeka kuri nyore kudonha.Kuti ikurumidze oxidation, musika ikozvino wawedzera nickel - mhangura - nickel plating nzira yekuita 24-96 maawa emunyu wekupfapfaidza.
3. Black Zinc: maererano nezvinodiwa nemutengi zvakagadziriswa zvemagineti pamusoro inogadziriswa kuita dema, iri pahwaro hwemabati emakemikari kurapwa kuti uwedzere dhiri remafirimu ekuchengetedza firimu, iyi firimu inogona zvakare kutamba maitiro ekugadzirisa magineti, kuwedzera nguva yekupfapfaidza munyu.Asi kutaridzika kwayo kuri nyore kukweshwa, kurasikirwa nekugadzirisa kwayo.
4. Black Nickel: ine zvinodiwa zvakafanana zveblack zinc plating, iri pahwaro hwe nickel plating mushure mekurapa kwekemikari kuti uwedzere chidimbu chefirimu rekuchengetedza dema.
5. Ndarama: inowanzoshandiswa mune jewelry magnet accessories, ikozvino kune akawanda anonyanya kufarirwa magineti maoko ekushongedza.
6. Epoxy resin: kuitira kuti uwedzere munyu wekupfapfaidza kuramba kune chigadzirwa, jira resin pendi rinowedzerwa kunze kwemagineti mushure me nickel plating, iyo yakawanda yakasviba.Iyo yekuputira ine yakanaka corrosion resistance kunze kweiyo magnet coating.Magnet orientation uye kuumba muhurongwa hwemagineti, zvichireva kuita magineti zvinhu kana kushaikwa kwemagineti yekuwedzera magineti.Kazhinji, chinhu chine magineti chingave chine magineti chinogona kuiswa musimba remagineti rinoumbwa necoil iyo inofambiswa nadzo ikozvino, uye iyo magineti mukati megineti inogadziriswa nekunze kwemagineti.
