IiMagnet zeMagnet ziwuchaphazela njani ukusebenza kwe-U Shaped Neodymium Magnets

Imagnethi emile njenge-U ye-neodymium inika ugxininiso lwamandla kazibuthe, kodwa bakwajongana nobuthathaka obukhethekileyo ngenxa yejometri yabo kunye nokuchaphazeleka kokuthotywa kwe-neodymium. Ngelixa i-alloy core ivelisa amandla amagnetic, i-coating yi-maleko yayo ebalulekileyo yokukhusela, ebeka ngokuthe ngqo ukusebenza kwayo, ukhuseleko kunye nobomi benkonzo. Ukujongana nokukhethwa kwengubo kunokukhokelela ekungaphumelelini kwangaphambi kwexesha, ukunciphisa amandla okanye ukuphuka okuyingozi.

Indima ebalulekileyo yeeNgqungquthela
Iimagnethi zeNeodymium zidla ngokukhawuleza xa zisesichengeni sokufuma, ukufuma, ityuwa okanye iikhemikhali, ezikhokelela ekuboleni kwamandla kazibuthe okungenakuguqulwa kunye nokonakala kwesakhiwo. Ubume obubume obungu-U buyenza ibe mandundu le mingcipheko: ukugoba kwayo okubukhali kwangaphakathi kugxininise uxinzelelo kumatshini, ijometri yayo ethintelweyo ibamba ungcoliseko, kunye namagophe ayo antsonkothileyo acela umngeni ukufana kwengubo. Ngaphandle kokhuseleko oluluqilima, umhlwa unokuqalisa kwigophe langaphakathi, ukhukulise ukuphuma kwemagnethi kwaye uqalise iintanda ezinokubangela ukuba umazibuthe wophuke.

IiCoatings zenza Ngakumbi kunoKhuseleko lokuMhlwa
Iingubo ezisebenzayo zisebenza njengezithintelo ezininzi ezikhuselayo: zenza umqobo womzimba ngokuchasene nezoyikiso zokusingqongileyo, ziphucula ukuxhathisa ukukrwela kunye ne-chipboard ngexesha lokuphatha, ukubonelela ukugquma kombane kwii-motor / sensors, kunye nokugcina ukubambelela phantsi koxinzelelo lwe-thermal. Ugutyulo lwekona enzulu lubalulekile kwiimagnethi ezimilise u-U-naziphi na izikhewu ziyakukhawulezisa ukuthotywa kokusebenza kwiindawo ezinoxinzelelo oluphezulu.

Ukuthelekiswa koKhetho oluqhelekileyo lweCoating
I-Nickel-Copper-Nickel (i-Ni-Cu-Ni) i-plating ayibizi kakhulu kwaye ibonelela ngokhuseleko olulungileyo olupheleleyo kunye nokumelana nokunxiba, kodwa kukho umngcipheko we-micro-porosity kunye nokugubungela okungalinganiyo kwi-U-bend, ngoko ifaneleka kakhulu kwizicelo ezomileyo zangaphakathi.
Iingubo ze-epoxy zigqwesa kwiindawo ezinqabileyo-iingubo zazo ezityebileyo, ezingaphezulu kwamanzi zingena nzulu kwi-bend, zibonelela ngokugqwesa ukufuma / ukuchasana kweekhemikhali kunye nokugquma kombane, kodwa zincama ukuxhathisa ukukrala.
I-Parylene inikezela ngokungenasiphako, i-pinhole-free-molecular encapsulation nakwizikhewu ezinzulu, okwenza kube yinto efanelekileyo kwiimeko ezinzima (unyango, i-aerospace), kodwa ukukhuselwa kwayo ngomatshini kulinganiselwe kwaye ixabiso layo liphezulu.
I-Zinc ingasetyenziselwa njengomaleko wedini kwindawo epholileyo apho inoqoqosho, kodwa ayinakho ukuqina kwexesha elide.
Igolide iqinisekisa ukuxhathisa i-corrosion kunye ne-conductivity kwi-specialty electronics, kodwa kufuneka isetyenziswe ngokubambisana ne-nickel yenkxaso yesakhiwo.

Isiphumo sokuKhethwa koMtyalo kwiNdlela yokuSebenza
Iingubo zinquma ngokuthe ngqo ukuzinza kwamagnetic-i-corrosion iyancipha ngokusisigxina amandla e-Gauss kunye nokutsala amandla. Ilawula imfezeko yesakhiwo ngokuthintela iintanda kwiigophe zangaphakathi ezingagqunywanga. Iqinisekisa ukhuseleko ngokuthintela amaqhekeza e-brittle agxininisiweyo. Ukususela kumbono wombane, iingubo zithintela iisekethe ezimfutshane (epoxy / parylene) okanye zivumela ukuhamba kwangoku (i-nickel / igolide). Ngokukrakra, iidyasi ezingahambelaniyo ziyasilela kwiindawo ezirhabaxa: iimagnethi ezisemgangathweni ezimilise okwe-nickel ezimilise okwe-U zidla ngokukhawuleza kwindawo emanzi, ngelixa iimagnethi ezingafakwanga zingaphazamisana ne-elektroniki ekufutshane.

Ukukhetha eyona Coating: Iingcamango eziphambili
Yibeke kuqala indawo osebenza kuyo: vavanya ukufuma, ukuguquguquka kobushushu, ukuvezwa kweekhemikhali, kunye nokusetyenziswa kwangaphakathi/kwangaphandle. Ukugqiba ubomi obufunekayo benkonzo-iimeko ezinzima zibiza i-epoxy okanye i-parylene coatings. Ukuchonga iimfuno zombane: i-insulation ibiza ii-epoxy / parylene coatings; ukuhanjiswa kufuna i-nickel/igolide yokwaleka. Vavanya ukusebenza ngoomatshini: iingubo ze-nickel zixhathisa ukunxiba kuneepoxy ezithambileyo zokwaleka. Njalo ugxininise i-bend coverage yangaphakathi-abathengisi kufuneka baqinisekise ukufana kule ndawo ngokusebenzisa iinkqubo ezikhethekileyo. Iindleko zokulinganisela kunye nemingcipheko: Imilinganiselo yokukhusela engachazwanga ngokwaneleyo inokukhokelela kwiintsilelo ezixabisa kakhulu. Kwizicelo ezibalulekileyo, gunyazisa uvavanyo lwesitshizi setyuwa

Sebenzisa ezona ndlela zilungileyo
Chaza ngokucacileyo uhlobo lokutyabeka kunye nobuncinci bobungqingqwa kwiinkcukacha (umzekelo, "30μm epoxy"). Funa abavelisi ukuba banike ubungqina obubhaliweyo bokhuseleko olungaphakathi. Sebenza kunye neengcali ezinamava kwi-U-shaped magnetic geometries-iinkqubo zabo zokugquma zilinganiswe kwiimilo ezinzima. Iiprototypes zovavanyo phantsi kweemeko zehlabathi lokwenyani phambi kwemveliso epheleleyo; zibeke kwimijikelo yobushushu, imichiza, okanye ukufuma ukuqinisekisa ukusebenza.

Isiphelo: Iingubo njengabaGcileli abaCwangcisiweyo
Kwimagnethi ye-neodymium emile okwe-U, ii-coatings ayilonyango lomphezulu, kodwa zilukhuselo olusisiseko lokuthembeka. Ukukhetha iingubo ze-epoxy zendawo emanzi, iingubo ze-parylene zokuchaneka kotyando, okanye iingubo zokugqoka ezenziwe ngobunjineli ukwenzela ukuqhuba kunokuguqula ubuthathaka bube bubunzima. Ngokuthelekisa ukusebenza kwengubo kwiimfuno zesicelo kunye nokuqinisekisa ukukhuselwa kwiindawo ezibalulekileyo, unokuqinisekisa ukusebenza okuphezulu komagnetic kumashumi eminyaka. Ungaze ulalanise kukhuseleko lokugquma: amandla akho umazibuthe axhomekeke kuwo.
