Neodymium Iron Boron Magnets ndeimwe yeakasimba kwazvo yekutengesa magineti aripo nhasi. Aya magineti epasi asingawanzo anogona kusimba kakapetwa ka10 pane yakasimba magineti eceramic. Magineti eNdFeB anowanzo kugadzirwa achishandisa imwe yemhando mbiri dzemhando dzemhando, akasungirirwa magineti (kumanikidza, jekiseni, extrusion kana kuumbwa kwekarenda), uye sintered magineti (upfu simbi, PM process). Magineti eNdFeB anowanzo shandiswa muzvigadzirwa zvinoda magineti akasimba echigarire senge hard disk drives emakomputa, mota dzemagetsi mumidziyo isina tambo, uye fasteners. Kune zvekurapa chikamu mashandisirwo matsva eaya magineti ane simba ari kubuda. Semuyenzaniso, catheter navigation, uko magineti anogona kubatanidzwa mumuromo wecatheter gungano uye inodzorwa nekunze magineti masisitimu ekugadzirisa uye kukanganisa kugona.
Zvimwe zvinoshandiswa mundima yekurapa zvinosanganisira kuunzwa kweakavhurika magineti resonance imaging (MRI) scanner ayo anoshandiswa kumepu uye mufananidzo anatomy, seimwe nzira kune superconducting magineti ayo anowanzo shandisa coils ewaya kugadzira magineti. Kuwedzera kushandiswa mumunda wemidziyo yekurapa kunosanganisira, kureba uye kwenguva pfupi maimplants, uye zvidiki zvinopinda. Zvimwe zvikumbiro zvinopinda zvishoma zveneodymium iron boron magineti magineti endoscopic emakumi ezviuru emaitiro anosanganisira; gastroesophageal, gastrointestinal, skeleton, tsandanyama uye majoini, mwoyo, uye neural.
Ferrite magineti, neodymium magineti kana kunyange magineti mabhesi anoshandiswa kune akasiyana maapplication muhunyanzvi, muindasitiri uye zvakare nezvinangwa zvekurapa. Pane chinodiwa chekupa magineti ane ekudzivirira pamusoro kubva pakuora, iyo "kunamira" kwemagineti. Kuisa neodymium magineti inzira yakakosha yekudzivirira magineti kubva mukuora. Iyo substrate NdFeB (Neodymium, Iron, Boron) ichaita oxidize nekukurumidza pasina danda rekudzivirira. Pazasi pane runyorwa rwekupfeka / kupfekedza uye minhenga yavo kune yako referensi.

NiCuNi coating: Iyo nickel coating inoumbwa netutatu, nickel-copper-nickel. Rudzi urwu rwekupfeka ndiyo inonyanya kushandiswa uye inopa dziviriro kubva mukuora kwemagineti mumamiriro ekunze. Mari yekugadzira yakaderera. Iyo yakanyanya tembiricha yekushanda ingangoita 220-240ºC (zvichienderana nehukuru hwekushanda tembiricha yemagineti). Rudzi urwu rwekupfekedza runoshandiswa mumainjini, majenareta, midziyo yekurapa, masensa, mashandisirwo emotokari, kuchengetedza, matete firimu deposition process uye pombi.
Black nickel: Zvimiro zvejasi iri zvakafanana neiyo nickel coating, nemusiyano wekuti imwe nzira inogadzirwa, dema nickel assembly. Zvivakwa zvakafanana neaya akajairwa nickel plating; nekunyanya kuti uku kupfekedzwa kunoshandiswa mumashandisirwo anoda kuti chimiro chechimiro chechidimbu hachina kupenya.
Ndarama: Rudzi urwu rwekupfekedza runowanzo shandiswa munharaunda yekurapa uye zvakare yakakodzera kushandiswa mukusangana nemuviri wemunhu. Pane mvumo kubva kuFDA (Food and Drug Administration). Pasi pechifukidzo chegoridhe pane sub-layer yeNi-Cu-Ni. Iyo yakanyanya kutonhora yekushanda inosvikawo 200 ° C. Mukuwedzera kune munda wemishonga, goridhe plating inoshandiswawo kune zvishongo uye zvinangwa zvekushongedza.
Zinc: Kana iyo yakanyanya tembiricha yekushanda iri pasi pe120 ° C, rudzi urwu rwekupfeka rwakakwana. Mari yacho yakadzikira uye magineti anodzivirirwa kubva mukuora mumhepo. Inogona kunama kune simbi, kunyangwe inonamira yakagadziridzwa inofanirwa kushandiswa. Iyo zinc coating yakakodzera chero zvipingamupinyi zvekudzivirira zvemagineti zvakaderera uye tembiricha yekushanda yakaderera inokunda.
Parylene: Kupfeka uku kunobvumidzwawo neFDA. Naizvozvo, dzinoshandiswa pakurapa zvikumbiro mumuviri wemunhu. Iyo yakanyanya kutonhora yekushanda inenge 150 ° C. The molecular structure ine ring-shaped hydrocarbon compounds inosanganisira H, Cl uye F. Zvichienderana nekugadzirwa kwema molecular, marudzi akasiyana-siyana anosiyaniswa se: Parylene N, Parylene C, Parylene D uye Parylene. HT.
Epoxy: Kupfekedza kunopa yakanakisa chipingamupinyi pamunyu nemvura. Iko kune kunamatira kwakanaka kwazvo kusimbi, kana magineti yakanamirwa neadhesive yakakosha yakakodzera magineti. Iyo yakanyanya tembiricha yekushanda inenge 150 ° C. Iyo epoxy coatings inowanzova yakasviba, asi inogonawo kuva yakachena. Zvishandiso zvinogona kuwanikwa muchikamu chemakungwa, injini, masensa, zvinhu zvevatengi uye chikamu chemotokari.
Magnets akaiswa mupurasitiki: kana anonziwo over-moulded. Hunhu hwayo hukuru kuchengetedzwa kwayo kwakanakisa kwemagineti kubva pakutsemuka, kukanganisa uye ngura. Iyo inodzivirira layer inopa dziviriro pamvura nemunyu. Iyo yakanyanya kupisa yekushanda inoenderana nepurasitiki inoshandiswa (acrylonitrile-butadiene-styrene).
Yakagadzirwa PTFE (Teflon): Kufanana nejekiseni / purasitiki coating inopawo yakanakisa dziviriro yemagineti kubva pakutyoka, kukanganisa uye ngura. Iyo magineti inodzivirirwa kubva pakunyorova, mvura nemunyu. Iyo yakanyanya tembiricha yekushanda inotenderedza 250 ° C. Ichi chifukidzo chinonyanya kushandiswa mumaindasitiri ekurapa uye muindasitiri yezvekudya.
Rubber: Rubber coating inodzivirira zvakakwana kubva pakuputsika uye kukanganisa uye kuderedza ngura. Iyo rabha zvinhu inoburitsa yakanaka kwazvo kutsvedza kuramba pane simbi. Iyo yakanyanya tembiricha yekushanda yakatenderedza 80-100 ° C. Pot magineti ane rubber coating ndiyo inonyanya kuoneka uye inoshandiswa zvakanyanya zvigadzirwa.
Isu tinopa vatengi vedu zano rehunyanzvi uye mhinduro dzekudzivirira magineti ako uye kuwana yakanyanya kunaka kushandisa magineti. Bata nesu uye isu tichafara kupindura mubvunzo wako.
