Indlela Izigqoko Zizibuthe Ezikuthinta Ngayo Ukusebenza Kozibuthe Be-U Shaped Neodymium Magnets

Ozibuthe be-neodymium abamise u-U banikeza amandla kazibuthe aphakeme kakhulu, kodwa futhi babhekana nokuba sengozini okuyingqayizivele ngenxa yejometri yabo kanye nokuba sengozini kokugqwala okungokwemvelo kwezinto ze-neodymium. Ngenkathi i-alloy core ikhiqiza amandla kazibuthe, ukumboza kuyingqimba yayo yokuvikela ebalulekile, enquma ngokuqondile ukusebenza kwayo, ukuphepha nokuphila kwesevisi. Ukweqa ukukhethwa kokumboza kungaholela ekuhlulekeni ngaphambi kwesikhathi, amandla ancishisiwe noma ukuphuka okuyingozi.

Iqhaza Elibalulekile Lezingubo
Ozibuthe be-Neodymium bagqwala ngokushesha lapho bechayeka kumswakama, umswakama, usawoti noma amakhemikhali, okuholela ekuboleni kwamandla kazibuthe okungenakulungiseka kanye nokuqina kwesakhiwo. Umumo omise okwe-U ubhebhethekisa lezi zingozi: ukugoba kwawo okucijile kwangaphakathi kugxilisa ukucindezeleka komshini, i-geometry yayo evimbile icupha ukungcola, futhi amajika ayo ayinkimbinkimbi abekela inselele ukufana kokugqoka. Ngaphandle kokuvikela okuqinile, ukugqwala kungaqala ejikeni elingaphakathi, kucekeleke phansi okukhiphayo kazibuthe futhi kuqalise imifantu engenza ukuthi uzibuthe aphuke.

Izigqoko Zenza Okungaphezu Kokuvikela Ukugqwala Nje
Izembatho ezisebenzayo zisebenza njengezithiyo eziningi ezivikelayo: zakha isithiyo esingokomzimba ngokumelene nezinsongo zemvelo, zithuthukisa ukumelana nokuklwejwa nokucwiywa ngesikhathi sokuphatha, zihlinzeke ngokufakwa kukagesi kumamotho/izinzwa, futhi zigcine ukunamathela ngaphansi kokucindezeleka okushisayo. Ukumbozwa kwekhona elijulile kubalulekile kumazibuthe amise okwe-U-noma yiziphi izikhala zizosheshisa ukuwohloka kokusebenza ezindaweni ezinengcindezi ephezulu.

Ukuqhathanisa Izinketho Zokuhlanganisa Okujwayelekile
Ukucwenga kwe-Nickel-Copper-Nickel (Ni-Cu-Ni) kubiza kancane futhi kunikeza isivikelo esihle sonke kanye nokumelana nokugqokwa, kodwa kunengozi ye-micro-porosity kanye nokumbozwa okungalingani ku-U-bend, ngakho-ke kulungele kangcono izinhlelo zokusebenza ezomile zasendlini.
Izembatho ze-epoxy zihamba phambili ezindaweni ezinokhahlo—ugqinsi lwazo, oluwuketshezi oluningi lungena lijule ejikeni, lunikeze ukumelana okuhle kakhulu komswakama/amakhemikhali kanye nokufakwa kukagesi, kodwa ludela ukumelana nokuklwebheka.
I-Parylene inikeza i-encapsulation yama-molecular engenasici, engena-pinhole ngisho nasezikhaleni ezijulile, okwenza kube kuhle ezimweni ezimbi kakhulu (izokwelapha, i-aerospace), kodwa ukuvikelwa kwayo kwemishini kunomkhawulo futhi izindleko zayo ziphezulu.
I-Zinc ingasetshenziswa njengesendlalelo somhlatshelo ezindaweni ezithambile lapho iyonga khona, kodwa ayinakho ukuqina kwesikhathi eside.
Igolide liqinisekisa ukumelana nokugqwala kanye ne-conductivity kuma-electronics akhethekile, kodwa lidinga ukusetshenziswa ngokuhambisana ne-nickel ukuze kusekelwe isakhiwo.

Umthelela Wokukhetha Kokunamathela Ekusebenzeni
Izembatho zinquma ngokuqondile ukuzinza kazibuthe—ukugqwala kunciphisa unomphela amandla e-Gauss namandla okudonsa. Ilawula ubuqotho besakhiwo ngokuvimbela imifantu kumajika angaphakathi angavaliwe. Iqinisekisa ukuphepha ngokuvimbela izingcezwana ezicindezelweyo. Ngokombono kagesi, ama-coatings avimbela ama-circuits (i-epoxy/parylene) noma anike amandla ukugeleza kwamanje (i-nickel/igolide). Ngokudabukisayo, ukunamathela okungafani kuyahluleka ezindaweni ezinokhahlo: omazibuthe abajwayelekile abamise okwe-nickel abamise okwe-U bagqwala ngokushesha ezindaweni ezimanzi, kuyilapho ozibuthe abangafakwanga insimbi bengaphazamisa izinto zikagesi eziseduze.

Ukukhetha I-Coating Best: Ukucatshangelwa Okubalulekile
Beka kuqala indawo osebenzela kuyo: hlola umswakama, ukushintshashintsha kwezinga lokushisa, ukuchayeka kwamakhemikhali, kanye nokusetshenziswa kwangaphakathi/ngaphandle. Nquma impilo yesevisi edingekayo-izimo ezinzima zibiza i-epoxy noma i-parylene coatings. Thola izidingo zikagesi: ukufakwa kwe-insulation kubiza ama-epoxy/parylene coatings; I-conductivity idinga ukumbozwa kwe-nickel/igolide. Linganisa ukusebenza komshini: izimbotshana ze-nickel zimelana kakhulu nokugqokwa kunezingubo ezithambile ze-epoxy. Ngaso sonke isikhathi gcizelela ukumbozwa kwe-inner bend—abathengisi kufanele baqinisekise ukufana kule ndawo ngezinqubo ezikhethekile. Ibhalansi yezindleko kanye nezingozi: Izinyathelo zokuvikela ezishiwo ngokunganele zingaholela ekuhlulekeni okubizayo. Ngezinhlelo zokusebenza ezibucayi, gunyaza ukuhlolwa kwesifutho sikasawoti

Sebenzisa imikhuba emihle kakhulu
Yisho ngokucacile uhlobo lokunamathela kanye nobukhulu obuncane ekucacisweni (isb, “30μm epoxy”). Idinga abakhiqizi ukuthi banikeze ubufakazi obubhaliwe bokufakwa kwe-inbend. Sebenza nochwepheshe abanolwazi kumajiyometri kazibuthe amise okwe-U—izinqubo zabo zokumboza ziyalinganiswa ukuze zibe yizimo eziyinkimbinkimbi. Hlola ama-prototypes ngaphansi kwezimo zomhlaba wangempela ngaphambi kokukhiqizwa okugcwele; zibeke obala emijikelezweni yezinga lokushisa, amakhemikhali, noma umswakama ukuze kuqinisekiswe ukusebenza kwawo.

Isiphetho: Izingubo njengabanakekeli Beqhinga
Kozibuthe be-neodymium abamise u-U, okokunamathela akuzona izindlela zokwelapha ezingaphezulu, kodwa ziyizivikelo eziyisisekelo zokwethembeka. Ukukhetha i-epoxy coatings yezindawo ezimanzi, i-parylene coatings yokunemba kokuhlinzwa, noma ama-plating akhiwe ngobunjiniyela be-conductivity kungaguqula ubuthakathaka bube ukuqina. Ngokufanisa ukusebenza kwe-coating nezidingo zohlelo lokusebenza kanye nokuqinisekisa ukuvikeleka ezindaweni ezibucayi kakhulu, ungaqinisekisa ukusebenza okuphakeme kazibuthe amashumi eminyaka. Ungalokothi ubeke engcupheni ekuvikelekeni kokumboza: amandla kazibuthe wakho ancike kukho.
