Indlela iiMagnet Coatings ezichaphazela ngayo ukusebenza kweeMagnet ze-U Shaped Neodymium

Iimagnethi ze-neodymium ezimile okwe-U zinika uxinaniso oluphezulu lwamandla emagnethi, kodwa zikwajongene nobuthathaka obukhethekileyo ngenxa yejometri yazo kunye nokuthambekela kokugqwala kwezinto ze-neodymium. Ngelixa i-alloy core ivelisa amandla emagnethi, i-coating yimaleko yayo ebalulekileyo yokukhusela, emisela ngokuthe ngqo ukusebenza kwayo, ukhuseleko kunye nobomi benkonzo. Ukungahoyi ukhetho lwe-coating kunokukhokelela ekusileleni kwangethuba, amandla anciphileyo okanye ukwaphuka okuyingozi.

Indima Ebalulekileyo Yeengubo
Iimagnethi zeNeodymium zibola ngokukhawuleza xa zichatshazelwe kukufuma, ukufuma, ityuwa okanye iikhemikhali, nto leyo ebangela ukubola kwamandla emagnethi angenakulungiseka kunye nokuqhekeka kwesakhiwo. Imilo efana no-U iyayandisa le mingcipheko: ukugoba kwayo kwangaphakathi okubukhali kugxininisa uxinzelelo loomatshini, i-geometry yayo ethintelweyo ibamba izinto ezingcolisayo, kwaye ii-curves zayo ezintsonkothileyo zijongene nokufana kwe-coating. Ngaphandle kokhuseleko oluqinileyo, ukugoba kunokuqala kwi-inner bend, kutshabalalise imveliso yemagnethi kwaye kuqalise iintanda ezinokubangela ukuba imagnethi iqhekeke.

Iingubo zenza okungaphezulu nje kokukhusela ukugqwala
Iingubo ezisebenzayo zisebenza njengezithintelo ezininzi zokukhusela: zenza umqobo womzimba nxamnye nezoyikiso zokusingqongileyo, zonyusa ukumelana nokukrweleka nokuqhekeka ngexesha lokuphathwa, zibonelela ngobushushu bombane kwiimoto/ii-sensors, kwaye zigcina ukunamathela phantsi koxinzelelo lobushushu. Ukugquma okunzulu kwikona kubaluleke kakhulu kwiimagnethi ezimile okwe-U—naziphi na izikhewu ziya kukhawulezisa ukuwohloka kokusebenza kwiindawo ezinoxinzelelo oluphezulu.

Ukuthelekiswa kweenketho zokugquma eziqhelekileyo
Iplating yeNickel-Copper-Nickel (Ni-Cu-Ni) ingabizi kakhulu kwaye inika ukhuseleko oluhle kunye nokumelana nokuguguleka, kodwa kukho umngcipheko we-micro-porosity kunye nokugquma okungalinganiyo kwi-U-bend, ngoko ke ifanelekile kakhulu kwiindlela zokusetyenziswa zangaphakathi ezomileyo.
Iingubo ze-epoxy zibalasele kwiindawo ezinzima—iingubo zazo ezijiyileyo nezimanzi zingena nzulu kwigophe, zibonelela ngokumelana nokufuma/iikhemikhali kunye nobushushu bombane, kodwa azinawo amandla okukrwela.
I-Parylene inika i-molecule encapsulation engenazimbobo, nokuba ikwizikhewu ezinzulu, nto leyo eyenza ukuba ilungele iimeko ezinzima (ezonyango, ezindizayo), kodwa ukhuseleko lwayo loomatshini lulinganiselwe kwaye ixabiso layo liphezulu.
I-Zinc ingasetyenziswa njengomaleko wokuncama kwiindawo ezithambileyo apho ingabizi kakhulu, kodwa ayinalo ixesha elide.
Igolide iqinisekisa ukumelana nokugqwala kunye nokuqhuba kombane kwii-elektroniki ezikhethekileyo, kodwa kufuneka isetyenziswe kunye ne-nickel ukuze kuxhaswe ulwakhiwo.

Isiphumo soKhetho lokuGcoba kwiNtsebenzo
Iingubo zimisela ngokuthe ngqo uzinzo lwemagnethi—ukugqwala kunciphisa ngokusisigxina amandla eGauss kunye namandla okutsala. Ilawula ukuthembeka kwesakhiwo ngokuthintela iintanda kwiindawo zangaphakathi ezingagqunywanga. Iqinisekisa ukhuseleko ngokuthintela iziqwenga ezixineneyo ezibuthathaka. Ngokwembono yombane, iingubo zithintela iisekethe ezimfutshane (epoxy/parylene) okanye zivumele ukuhamba kombane (nickel/gold). Okubaluleke kakhulu, iingubo ezingahambelaniyo ziyasilela kwiindawo ezinzima: iimagnethi ezisemgangathweni ze-U ezifakwe i-nickel zigqwala ngokukhawuleza kwiindawo ezimanzi, ngelixa iimagnethi ezingagqunywanga zinokuphazamisana nezixhobo ze-elektroniki ezikufutshane.

Ukukhetha Eyona Ngqubuthelo Ilungileyo: Izinto Ezibalulekileyo Omele Uziqwalasele
Beka phambili imeko-bume yokusebenza kwakho: vavanya umswakama, ukuguquguquka kobushushu, ukuvezwa kweekhemikhali, kunye nokusetyenziswa ngaphakathi/ngaphandle. Chonga ubomi benkonzo obufunekayo—iimeko ezinzima zifuna ii-epoxy okanye ii-parylene coatings. Chonga iimfuno zombane: ii-insulation calls zee-epoxy/parylene coatings; i-conductivity calls zee-nickel/gold coatings. Vavanya ukusebenza koomatshini: ii-nickel coatings ziyakwazi ukumelana nokuguguleka kunee-epoxy coatings ezithambileyo. Soloko ugxininisa ukugquma kwangaphakathi—abathengisi kufuneka baqinisekise ukufana kule ndawo ngeenkqubo ezikhethekileyo. Ukulinganisela iindleko kunye nemingcipheko: Amanyathelo okukhusela angachazwanga ngokwaneleyo anokubangela ukusilela okubiza kakhulu. Kwizicelo ezibalulekileyo, yalela uvavanyo lwe-salt spray

Sebenzisa iindlela ezilungileyo
Xela ngokucacileyo uhlobo lwengubo kunye nobukhulu obuncinci kwiinkcukacha (umz., “30μm epoxy”). Funa abavelisi ukuba banike ubungqina obubhaliweyo bokugubungela okungaphakathi. Sebenzisana neengcali ezinamava kwiijiyometri zemagnethi ezimile okwe-U—iinkqubo zabo zokugquma zilinganiswa kwiimo ezintsonkothileyo. Vavanya iiprototypes phantsi kweemeko zehlabathi lokwenyani ngaphambi kokuba zivelise ngokupheleleyo; zibeke kwimijikelo yobushushu, iikhemikhali, okanye umswakama ukuqinisekisa ukusebenza.

Isiphelo: Iingubo njengabagcini bobuchule
Kwiimagnethi ze-neodymium ezimile okwe-U, ukugquma akuyonto yonyango lomphezulu, kodwa kukukhusela okusisiseko kokuthembeka. Ukukhetha ukugquma kwe-epoxy kwiindawo ezimanzi, ukugquma kwe-parylene ngokuchanekileyo kotyando, okanye ukugquma okwenziwe ngobunjineli ukuze kuqhume amandla kunokuguqula ubuthaka bube bubunzima. Ngokuthelekisa ukusebenza kokugquma neemfuno zesicelo kunye nokuqinisekisa ukhuseleko kwii-inbends ezibalulekileyo, unokuqinisekisa ukusebenza okuphezulu kwemagnethi kangangamashumi eminyaka. Ungaze uyeke ukhuseleko lokugquma: amandla akho emagnethi axhomekeke kuyo.
