Kurapa Kwepamusoro kweMagineti
Kurapa kwepamusoro kweneodymium maginetiinoita basa rakakosha mukuita kwavo uye hupenyu hurefu.Neodymium magineti, anozivikanwawo seNdFeB magineti, ane simba rakanyanyisa magineti akagadzirwa kubva kune alloy yesimbi, boron, uye neodymium.Kurapa kwepamusoro kunoreva maitiro ekuisa chivharo chekudzivirira kana coating kune yekunze pamusoro peneodymium magineti.Kurapa uku kunodiwa kudzivirira magineti kubva mukuora uye kuvandudza kusimba kwayo kwese.Mhando dzakajairika dzekurapa kwepamusoro kune neodymium magineti dzinosanganisira NiCuNi plating, Zinc plating, uye Epoxy coating.
Chimwe chezvikonzero chikuru nei kurapwa kwepamusoro kwakakosha kune neodymium magineti iko kukanganisa kwavo mukuora.Neodymium magineti anonyanya kuumbwa nesimbi, iyo inowanzoita ngura kana yaiswa muhunyoro uye oksijeni.Nekushandisa chivharo chekudzivirira, ngura inogona kuderedzwa zvakanyanya, ichiwedzera hupenyu hwemagineti.
Chimwe chikonzero chekurapa kwepamusoro ndechekusimudzira kushanda kwemagineti.Iko kupfekedza kunogona kupa nzvimbo yakatsetseka, kuderedza kukwesha uye kubvumira zviri nani magineti zvivakwa.Mamwe marapirwo epamusoro, senge nickel plating kana goridhe plating, anogona kuvandudza magineti kuramba tembiricha, zvichiita kuti ive yakakodzera kune maapplication anosanganisira kupisa.Kurapa kwepamusoro zvakare kunogonesa neodymium magineti kuti ienderane nenzvimbo dzakasiyana siyana uye mashandisirwo.Semuenzaniso, epoxy coatings inogona kupa insulation, ichibvumira magineti kuti ishandiswe mumashandisirwo emagetsi pasina kupfupika-kutenderera.Coatings anogona zvakare kuchengetedza magineti kubva kumakemikari kana abrasion, zvichiita kuti ive yakakodzera kushandiswa munzvimbo dzinoita ngura kana mumashandisirwo ane friction uye kupfeka kuripo.
Kurapa kwepamusoro kunodiwa kune neodymium magineti kudzivirira kubva mukuora, kuwedzera mashandiro, kuwedzera kusimba, uye kuve nechokwadi kuenderana nekwakati nharaunda uye mashandisirwo.Nekushandisa iyo yakakodzera yepamusoro kurapwa, hupenyu uye kushanda kweneodymium magineti kunogona kuvandudzwa zvakanyanya.
Pazasi pane runyorwa rwekupfeka / kupfekedza uye minhenga yavo kune yako referensi.

Types of coatings for magineti
NiCuNi: Iyo nickel coating inoumbwa netutatu, nickel-mhangura-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 muinjini, jenareta, midziyo yekurapa, masensa, mota kunyorera, kuchengetedza, yakaonda firimu deposition process, uye pombi.
Black Nickel: Zvimiro zvejasi iri zvakafanana neiyo nickel coating, nemusiyano wekuti imwe nzira inogadzirwa, iyo 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 yakakodzerawo 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 isingasviki 120 ° 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 kupisa tembiricha inosvika 150 ° C. Iyo molecular chimiro ine ring-shaped hydrocarbon compounds inosanganisira H, Cl, uye F. Zvichienderana nekugadzirwa kwema molecular, marudzi akasiyana anosiyaniswa seParylene N, Parylene C, Parylene D, uye. Parylene HT.
Epoxy: Kupfeka 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 chemugungwa, injini, masensa, zvinhu zvevatengi, uye chikamu chemotokari.
Magnets akaiswa mupurasitiki: anonziwo over-molded.Chimiro chayo chikuru kuchengetedza kwayo kwakanaka 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 / epurasitiki coating zvakare inopa yakanakisa dziviriro yemagineti kubva pakutyoka, kukanganisa, uye ngura.Iyo magineti inodzivirirwa kubva pakunyorova, mvura, uye munyu.Iyo yakanyanya tembiricha yekushanda inotenderedza 250 ° C. Ichi chifukidzo chinonyanya kushandiswa mumaindasitiri ekurapa uye muindasitiri yezvekudya.
Rubber: Iyo rubha yakavhara inodzivirira zvakakwana kubva pakuputsika uye zvinokanganisa uye inoderedza 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 avo uye kuwana yakanyanya kunaka kushandisa magineti.Taura nesuuye isu tichafara kupindura mubvunzo wako.
