I-Neodymium Iron Boron Magnets ingenye yezibuthe ezinamandla kakhulu zezentengiselwano ezitholakala namuhla.Lezi zibuthe zomhlaba eziyivelakancane zingaba namandla izikhathi eziphindwe ka-10 kunozibuthe we-ceramic onamandla kakhulu.Ozibuthe be-NdFeB bavame ukukhiqizwa kusetshenziswa esinye sezigaba ezimbili zezindlela ezijwayelekile, omagnet ababoshiwe (ukucindezela, umjovo, ukukhishwa kwe-extrusion noma ukubumba ikhalenda), kanye nozibuthe aba-sintered (i-powder metallurgy, inqubo ye-PM).Ozibuthe be-NdFeB bavame ukusetshenziswa emikhiqizweni edinga ozibuthe abaqinile abangapheli njengama-hard disk drive amakhompyutha, amamotho kagesi emishinini engenazintambo, nezixhumi.Ezisetshenziswa zengxenye yezokwelapha ukusetshenziswa okusha kwalezi zibuthe ezinamandla ziyavela.Isibonelo, ukuzulazula kwe-catheter, lapho omazibuthe bengahlanganiswa esihlokweni sokuhlanganiswa kwe-catheter futhi kulawulwe amasistimu kazibuthe angaphandle wokuqondisa kanye nekhono lokuphambuka.
Okunye okusetshenziswa emkhakheni wezokwelapha kufaka phakathi ukwethulwa kwezithwebuli ze-open magnetic resonance imaging (MRI) ezisetshenziselwa ukwenza imephu nesithombe sokwakheka komzimba, njengenye indlela yozibuthe abakhulu kakhulu abasebenzisa amakhoyili ezintambo ukukhiqiza inkambu kazibuthe.Ukusetshenziswa okwengeziwe emkhakheni wemishini yezokwelapha kufaka phakathi, izimila zesikhathi eside nezesikhathi esifushane, kanye nemishini ehlasela kancane.Ezinye izinhlelo zokusebenza ezingangeneleli kancane zozibuthe be-neodymium iron boron ziyi-endoscopic assemblies yenqwaba yezinqubo ezihlanganisa;i-gastroesophageal, i-gastroesophageal, i-skeleton, imisipha namalunga, i-cardiovascular, ne-neural.
Ozibuthe be-Ferrite, ozibuthe be-neodymium noma izisekelo kazibuthe zisetshenziselwa izinhlelo zokusebenza ezihlukahlukene kwezobuchwepheshe, embonini kanye nezinjongo zezokwelapha.Kunesidingo sokuhlinzeka ngozibuthe ngesivikelo esingaphezulu ekugqwaleni, “okuwukumboza” kuzibuthe.Ukufaka izibuthe ze-neodymium kuyinqubo ebalulekile yokuvikela uzibuthe ekugqwaleni.I-substrate i-NdFeB (i-Neodymium, i-Iron, i-Boron) izokhipha i-oxidize ngokushesha ngaphandle kongqimba oluyisivikelo.Ngezansi kunohlu lwe-plating/coating kanye nezimpaphe zazo ukuze uthole ireferensi yakho.

I-NiCuNi coating: 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 lokumboza lusetshenziswa ezinjinini, kumajeneretha, emishinini yezokwelapha, izinzwa, izinhlelo zokusebenza zezimoto, ukugcinwa, izinqubo 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 lokumboza luvame ukusetshenziswa emkhakheni wezokwelapha futhi lufanelekile ukusetshenziswa lapho kuthintana 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.
I-Zinc: Uma izinga lokushisa eliphezulu lokusebenza lingaphansi kuka-120 ° C, lolu hlobo lokumboza 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.Ukushisa okuphezulu okusebenzayo cishe ku-150 ° C. Isakhiwo samangqamuzana siqukethe i-hydrocarbon emise okwendandatho ehlanganisa i-H, Cl no-F. Ngokuya ngesakhiwo samangqamuzana, izinhlobo ezahlukene zihlukaniswa ngokuthi: I-Parylene N, i-Parylene C, i-Parylene D ne-Parylene. HT.
I-Epoxy: I-coating ehlinzeka ngokuvimbela okuhle 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.
Ozibuthe bajovwe ngepulasitiki: noma babuye babizwe ngokuthi ababunjwe ngokweqile.Isici sawo esiyinhloko ukuvikela kwawo okuhle kakhulu kukazibuthe ekuqhekekeni, emiphumeleni nasekugqwaleni.Ungqimba oluvikelayo lunikeza isivikelo emanzini nosawoti.Ukushisa okuphezulu okusebenzayo kuncike epulasitiki esetshenzisiwe (acrylonitrile-butadiene-styrene).
I-PTFE Eyakhiwe (i-Teflon): Njengomjovo / ipulasitiki enamathelayo ihlinzeka ngokuvikeleka okuhle kakhulu kukazibuthe ekuqhekekeni, imithelela kanye nokugqwala.Uzibuthe uvikelekile kumswakama, amanzi nosawoti.Ukushisa okuphezulu okusebenzayo kuzungeze i-250 ° C. Lokhu kunamathela kusetshenziswa ikakhulukazi ezimbonini zezokwelapha nasembonini yokudla.
Irabha: Injoloba ivikela ngokuphelele ekuqhekekeni kanye 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 amakhasimende ethu izeluleko zochwepheshe nezisombululo zendlela yokuvikela odonsa bakho futhi bathole ukusetshenziswa okuhle kakhulu kukazibuthe.Xhumana nathi futhi sizokujabulela ukuphendula umbuzo wakho.
