Yintoni iMagnet eSisigxina?Zeziphi iindidi ezikhoyo?
Iiparamitha ezimbini ezibalulekileyo-i-remanence kunye ne-coercitivity-ichaza i-magnet esisigxina, into enokuthi ivelise i-magnetic flux xa ifakwe kwi-magnetic field yangaphandle.
Ngokuqhelekileyo, i-intrinsic coercitivity yemagnethi esisigxina (Hcj) ingaphezulu kwe-300kOe (kwiyunithi yeCGS) okanye i-24kA/m (kwiyunithi ye-SI).Ukukwazi kwemagnethi esisigxina ukuxhathisa i-demagnetization, efana nokususwa kweemagnethi kubushushu obusebenzayo kwiinjini ezahlukeneyo kunye/okanye usetyenziso lomatshini wombane, kunye nombane okanye imagnethi yesekethe yendima yemagnetic demagnetization, yonyuka ngokunyanzeliswa.
Xa kuthelekiswa nozibuthe we-electromagnetic, osebenza kuphela njengomazibuthe xa umsinga wombane udlula kuwo, umazibuthe osisigxina worhwebo ufuna ukulungiswa okuphezulu kunye nokunyanzeliswa ngexabiso elifanelekileyo.
Ngawaphi aMalungu enza uMazibuthe osisigxina?Zeziphi iindidi ezikhoyo?
Iimagnethi ezisisigxina zenziwe ngezinto eziqinileyo ze-ferromagnetic, ezizezo zithi, xa sele zenziwe nguzibuthe, zigcine iimpawu zazo zemagnethi de zikhutshwe yimagnethi, into eyenzekayo xa kusetyenziswa umhlaba wemagnethi ochasene nendawo yokuqala.
Imagnethi esisigxina yenziwe ngezi zinto zilandelayo:
-- OwaziwayoNdFeB, i-NIB, kunye ne-Neo zenziwe nge-neodymium, i-iron, kunye ne-boron alloy.
Xa isixa esikhulu se-iron (III) oxide (Fe2O3, irust) zidityaniswe nezixa ezincinci zenye okanye ngaphezulu kwezinye izinto zetsimbi, ezifana ne-strontium, i-barium, i-manganese, i-nickel, kunye ne-zinc, ziyaxutywa kwaye zigxothwe ukuze zidale.ferrite, uhloboceramicimpahla.
-- Cobalt-Samarium.Iquka i-samarium kunye ne-cobalt alloy, njengoko igama layo libonisa.
-- Alnicoibhekisela kwiqela le-alloys yentsimbi, ukongeza kwintsimbi, kwakhona iqulethe ixabiso elibalulekileyo leentsimbi ze-aluminium (Al), i-nickel (Ni), kunye ne-cobalt (Co).
--Iimagnethi eziguquguqukayozizinto eziyintlanganisela enamalungu azibuthe alungelelaniswe kwimatrix ye-elastomer.
A umazibuthe neodymiumngoyena umazibuthe unamandla ehlabathini, ukanti kukho umahluko phakathi kwayo nemagnethi yesamarium.
Ziqukasintered, idityanisiwe, idityanisiwe (icinezelwe, itofwe, i-extruded, kunye ne-calendered), kunye neemagnethi ezicinezelekileyo ngokumalunga neenkqubo zemveliso.
Eyona minerali yendalo yamagnetic, imagnetite (Fe 3 O 4), yenye yezinto ezisetyenziselwa ukwenza iimagnethi ezisisigxina.Nangona imagnethi yayo iphakathi xa ithelekiswa nobukhulu bayo, uMhlaba ngokwawo unguzibuthe osisigxina.Ukusukela ekuphuhlisweni kwekhampasi kwi-China yakudala, abantu basebenzise umhlaba wemagnethi ukuze bahambe.
Nangona izicelo zabo zinyanzelwa yinyaniso yokuba kwanabona magnethi banamandla asisigxina angomelelanga njengezona magnethi zinamandla, oomazibuthe abasisigxina nangona kunjalo banoluhlu olubanzi losetyenziso, olufana nokusetyenziswa kwemagnethi ye-neodymium kwiimotor zombane.Nangona kunjalo, iimagnethi zikho yonke indawo kwaye zinokufumaneka kwiindawo ngeendawo, kubandakanya:
-- Ihadi drayivu.
-- Omabini amakhadi okuthenga ngetyala kunye nee-ATM.
-- Imakrofoni kunye nezithethi.
I-electromagnetic kunye nemagnethi esisigxina idibanisa ukuqhuba iimotor zombane.
Yintoni indlela umazibuthe osisigxina?
Njengaye nawuphi na omnye umazibuthe, umazibuthe ngamnye osisigxina uvelisa indawo yemagnethi erhintyela ngendlela eyahlukileyo ejikeleze umazibuthe.Amandla kunye nobukhulu bemagnethi banempembelelo kwindlela enkulu ngayo imagnethi.Iifayile zentsimbi ezisasazeke zijikeleze umazibuthe webar, ezithi zijongiswe ngokukhawuleza kwimigca yentsimi, yeyona ndlela ilula yokubona umhlaba wemagnethi oveliswa yimagnethi esisigxina.
Iipali ezimbini zemagnethi nganye esisigxina zaziwa njengeemantla nasezantsi, nangona kunjalo, zisenokubizwa ngokuba ngu-A no-B.Iipali ezichasayo zemagnethi kufuneka zigcinwe kunye nomsebenzi omninzi, ngelixa iipali zayo ezinomtsalane kufuneka zisuswe ngomzamo.Ezona magnethi zinamandla zitsala ngamandla kangangokuba zikwazi ukutsala ulusu endleleni yazo.
Iimagnethi ezisisigxina yayikuphela kwemagnethi efumaneka eluntwini kangangamawaka eminyaka.Kuphela ngo-1823 kwaqala ukwenziwa i-electromagnetic.Iimagnethi zazidla ngokuba zizinto ezintsha ngaphambi koko.Nayiphi na into ye-ferromagnetic, efana nekliphu yentsimbi, inokuqhuba umsinga usebenzisa i-electromagnetic.Nangona kunjalo, umphumo uphela ngokukhawuleza.
Nokuba kunjaloNeodymium Iron Boron Magnets, Iimagnethi zeFerrite, AlNiCo Magnets, Iimagnethi zeSamarium Cobalt, Iimagnethi eziguquguqukayo, Iindibano zeMagnetic, okanyeisiXhobo seMagnetic kunye nesiXhobo, singakuvuyela ukukunceda wenze isigqibo sokuba yeyiphi inketho efanelekileyo kwisicelo sakho.Sitsalele umnxeba ku-86-135-6789-1907 okanye uthumele i-imeyile kuyosales@honsenmagnetics.com.
