Ukwelashwa Okungaphezulu Kwamazibuthe
Ukwelashwa okungaphezulu kweizibuthe ze-neodymiumidlala indima ebalulekile ekusebenzeni kwabo nasekuphileni isikhathi eside. Ozibuthe be-Neodymium, ababuye babizwe ngokuthi ngozibuthe be-NdFeB, bangozibuthe abangapheli abanamandla ngokwedlulele abenziwe nge-alloy yensimbi, i-boron, ne-neodymium. Ukwelashwa okungaphezulu kubhekisela ohlelweni lokusebenzisa ungqimba oluyisivikelo noma ukunamathela endaweni engaphandle kazibuthe we-neodymium. Lokhu kwelashwa kuyadingeka ukuze kuvinjwe uzibuthe ukuthi ungagqwali futhi uthuthukise ukuqina kwawo kukonke. Izinhlobo ezivame kakhulu zokwelapha ezingaphezulu kozibuthe be-neodymium zifaka i-NiCuNi plating, i-Zinc plating, ne-Epoxy coating.
Esinye sezizathu eziyinhloko zokuthi kungani ukwelashwa okungaphezulu kubalulekile kuzibuthe ze-neodymium ukuthi zisengozini yokugqwala. Ozibuthe be-Neodymium bakhiwe ngokuyinhloko ngensimbi, ejwayele ukugqwala lapho evezwe kumswakama nomoya-mpilo. Ngokusebenzisa i-coating yokuzivikela, ukugqwala kungancishiswa kakhulu, kwandise isikhathi sokuphila sikazibuthe.
Esinye isizathu sokwelashwa okungaphezulu ukuthuthukisa ukusebenza kukazibuthe. I-coating inganikeza indawo ebushelelezi, inciphise ukungqubuzana futhi ivumele izakhiwo ezingcono kazibuthe. Ukwelapha okuthile okungaphezulu, okufana ne-nickel plating noma i-golden plating, kungathuthukisa ukumelana kukazibuthe emazingeni okushisa aphezulu, kuyenze ifanele ukusetshenziswa okubandakanya ukushisa. Ukwelashwa kwendawo engaphezulu futhi kwenza omagnethi be-neodymium bahambisane nezindawo ezahlukahlukene kanye nezinhlelo zokusebenza. Isibonelo, ama-epoxy coatings angahlinzeka ngokufakwa, okuvumela ukuthi uzibuthe usetshenziswe ezinhlelweni zikagesi ngaphandle kokujikeleza isikhashana. Ama-coatings angaphinda avikele uzibuthe kumakhemikhali noma ekuhutsheni, awenze afaneleke ukusetshenziswa endaweni ebolayo noma ezindaweni lapho kukhona ukungqubuzana nokuguga.
Ukwelashwa okungaphezulu kuyadingeka ukuze izibuthe ze-neodymium zivikeleke ekugqwaleni, zithuthukise ukusebenza, zikhulise ukuqina, futhi ziqinisekise ukuhambisana nendawo ethile kanye nezinhlelo zokusebenza. Ngokusebenzisa ukwelashwa kwendawo efanele, isikhathi sokuphila nokusebenza kahle kwezibuthe ze-neodymium kungathuthukiswa kakhulu.
Ngezansi kunohlu lwe-plating/coating kanye nezimpaphe zazo ukuze uthole ireferensi yakho.

Izinhlobo zokumboza ozibuthe
NiCuNi: I-nickel coating yenziwe ngezingqimba ezintathu, i-nickel-copper-nickel. Lolu hlobo lwe-coating lusetshenziswa kabanzi futhi luhlinzeka ngokuvikeleka ekugqwaleni kukazibuthe ezimweni zangaphandle. Izindleko zokucubungula ziphansi. Izinga lokushisa eliphezulu lokusebenza licishe libe ngu-220-240ºC (kuye ngokuthi izinga lokushisa eliphakeme kakhulu likazibuthe). Lolu hlobo lwe-coating lusetshenziswa ezinjinini, kumajeneretha, emishinini yezokwelapha, ezinzwa, ezisetshenziswa zezimoto, ekugcinweni, ezinqubweni zokubeka ifilimu emincane, namaphampu.
I-Nickel Emnyama: Izakhiwo zalesi sigqoko zifana nalezo ze-nickel coating, umehluko wokuthi inqubo eyengeziwe ikhiqizwa, ukuhlanganiswa kwe-nickel emnyama. Izakhiwo ziyefana nalezo ezijwayelekile ze-nickel plating; ngokukhethekile ukuthi lokhu kufakwa kusetshenziselwa izinhlelo zokusebenza ezidinga ukuthi isici esibonakalayo sesiqephu singakhanyi.
Igolide: Lolu hlobo lokugqoka luvame ukusetshenziswa emkhakheni wezokwelapha futhi lufanelekile ukusetshenziswa ekuthintaneni nomzimba womuntu. Kunemvume evela ku-FDA (Ukuphathwa Kokudla Nezidakamizwa). Ngaphansi kwengubo yegolide, kune-sub-layer ye-Ni-Cu-Ni. Ukushisa okuphezulu okusebenzayo nakho kumayelana ne-200 ° C. Ngaphandle kwensimu yezokwelapha, i-plating yegolide isetshenziselwa ubucwebe kanye nezinhloso zokuhlobisa.
Zinc: Uma izinga lokushisa eliphezulu lokusebenza lingaphansi kuka-120 ° C, lolu hlobo lokugqoka lwanele. Izindleko ziphansi futhi uzibuthe uvikelekile ekugqwaleni emoyeni ovulekile. Inganamathiselwa ensimbi, nakuba kufanele kusetshenziswe ingcina eyenziwe ngokukhethekile. I-zinc enamathela ifanelekile inqobo nje uma izithiyo zokuzivikela zikazibuthe zingamazinga okushisa aphansi futhi aphansi okusebenza akhona.
I-Parylene: Lokhu kunamathela kugunyazwe yi-FDA. Ngakho-ke, zisetshenziselwa izicelo zezokwelapha emzimbeni womuntu. Izinga lokushisa eliphakeme lokusebenza licishe libe ngu-150 ° C. Isakhiwo samangqamuzana siqukethe inhlanganisela ye-hydrocarbon emise okwendandatho ehlanganisa i-H, Cl, no-F. Ngokuya ngesakhiwo samangqamuzana, izinhlobo ezahlukene zihlukaniswa njenge-Parylene N, Parylene C, Parylene D, kanye I-Parylene HT.
I-Epoxy: Ukugqoka okunikeza umgoqo omuhle kakhulu ngokumelene nosawoti namanzi. Kukhona ukunamathela okuhle kakhulu ensimbi, uma i-magnet ihlanganiswe ne-adhesive ekhethekile efanelekayo odonsa. Izinga lokushisa eliphezulu lokusebenza lilinganiselwa ku-150 ° C. Izingubo ze-epoxy ngokuvamile zimnyama, kodwa zingaba mhlophe. Izicelo zingatholakala emkhakheni wezasolwandle, izinjini, izinzwa, izimpahla zabathengi, kanye nomkhakha wezimoto.
Omazibuthe afakwe epulasitiki: zibizwa nangokuthi zibunjwe ngokweqile. Isici sawo esiyinhloko ukuvikela kwawo okuhle kakhulu kukazibuthe ekuqhekekeni, emithelela, nasekugqwaleni. Ungqimba oluvikelayo lunikeza isivikelo emanzini nosawoti. Ukushisa okuphezulu okusebenzayo kuncike epulasitiki esetshenzisiwe (acrylonitrile-butadiene-styrene).
Kwakhiwe i-PTFE (Teflon): Njengomjovo / ipulasitiki enamathela futhi inikeza isivikelo esihle kakhulu uzibuthe ngokumelene nokuphuka, imithelela, kanye nokugqwala. Uzibuthe uvikelekile emswakameni, emanzini, nakusawoti. Ukushisa okuphezulu okusebenzayo kuzungeze i-250 ° C. Lokhu kunamathela kusetshenziswa ikakhulukazi ezimbonini zezokwelapha nasembonini yokudla.
Irabha: I-rubber coating ivikela ngokuphelele ekuqhekekeni nemithelela futhi inciphisa ukugqwala. Izinto zenjoloba zikhiqiza ukumelana okuhle kakhulu kokushelela ezindaweni zensimbi. Ukushisa okuphezulu okusebenzayo kuzungeze i-80-100 ° C. Ozibuthe basebhodweni abane-rubber coating yimikhiqizo esobala kakhulu futhi esetshenziswa kabanzi.
Sinikeza amaklayenti ethu izeluleko zochwepheshe kanye nezixazululo zendlela yokuvikela omazibuthe bawo futhi bathole ukusetshenziswa okuhle kakhulu kukazibuthe.Xhumana nathifuthi sizokujabulela ukuphendula umbuzo wakho.
