Abahlobo abaqhelene neemagnethi bayazi ukuba iimagnethi ze-iron boron zibonwa ngoku kwimarike yemagnethi yezixhobo zokusebenza njengempahla yemagnethi enexabiso eliphezulu.Zenzelwe ukusetyenziswa kwiindidi ezahlukeneyoishishini lobugcisa obuphezulus, kubandakanywa ukhuselo lwesizwe kunye nomkhosi, iteknoloji ye-elektroniki, kunye nezixhobo zonyango, iimoto, izixhobo zombane, izixhobo zombane, kunye nezinye iinkalo.Okukhona zisetyenziswa, kokukhona kulula ukuchonga imiba.Phakathi kwezi, i-demagnetization ye-iron-boron imagnethi eqinile kwimimiselo yobushushu obuphezulu ifumene umdla omkhulu.Okokuqala kunye nokuphambili, kufuneka siqonde ukuba kutheni i-NeFeB ikhupha imagnethi kwiindawo eziphezulu zokushisa.
Ulwakhiwo lomzimba lwe-Ne iron boron lumisela ukuba kutheni le nto ikhupha imagnethi kwindawo yobushushu obuphezulu.Ngokubanzi, umazibuthe unokuvelisa umhlaba wamagnetic kuba ii-electron ezithuthwa yi-elektroni ngokwazo zijikeleza ii-athomu zisiya kwicala elithile, okukhokelela kumandla kazibuthe onempembelelo ekhawulezileyo kwimiba edibeneyo ejikelezileyo.Nangona kunjalo, iimeko ezithile zobushushu kufuneka kuhlangatyezwane nazo ukuze ii-electron zijikeleze ii-athomu kwindawo ethile.Ukunyamezela ubushushu kuyahluka phakathi kwezixhobo zemagneti.Xa iqondo lobushushu liphakama kakhulu, ii-electron ziyalahleka kwi-orbit yazo yokuqala, nto leyo ekhokelela kwisiphithiphithi.Oku Ngeli xesha, indawo yemagnethi yasekhaya yemagnethi iya kuphazamiseka, kubangeledemagnetization.Iqondo lobushushu le-demagnetization yentsimbi ye-boron ibonwa ngokubanzi kukwakheka kwayo okukhethekileyo, amandla emagnethi, kunye nembali yonyango lobushushu.Uluhlu lweqondo lobushushu le-demagnetization kwi-boron yentsimbi yegolide luqhelekile phakathi kwe-150 kunye ne-300 degrees celcius (302 kunye ne-572 degrees Fahrenheit).Kolu luhlu lwamaqondo obushushu, iimpawu ze-ferromagnetic ziya zisiba mbi de zilahleke ngokupheleleyo.
Izisombululo ezininzi eziphumeleleyo kwi-NeFeB umazibuthe wobushushu obuphezulu be-demagnetization:
Okokuqala nokuphambili, musa ukutshisa kakhulu imveliso yemagnethi ye-NeFeB.Gcina iliso elibukhali kubushushu bayo obubalulekileyo.Ubushushu obubalulekileyo bezizibuthe ze-NeFeB buqhelekile bumalunga nama-80 degrees celcius (176 degrees Fahrenheit).Lungisa indawo yayo yokusebenza ngokukhawuleza.I-Demagnetization inokuncitshiswa ngokunyusa ubushushu.
Okwesibini, kukuqala ngetekhnoloji yokuphucula ukusebenza kweemveliso ezisebenzisa imagnethi yehairpin ukuze zibe nesakhiwo esifudumeleyo kwaye zingachaphazeleki kancinci kwiimpembelelo zokusingqongileyo.
Okwesithathu, kunye nemveliso yamandla kazibuthe efanayo, unokukhethaizinto zokunyanzeliswa okuphezulu.Ukuba oko kuyasilela, unokunikezela kuphela ixabiso elincinci lemveliso yamandla kazibuthe ukuze ufezekise ukunyanzeliswa okuphezulu.
I-PS: Isixhobo ngasinye sineempawu ezahlukeneyo, ngoko ke khetha efanelekileyo kunye neyoqoqosho, kwaye uyiqwalasele ngokucophelela xa uyila, ngaphandle koko kuya kubangela ilahleko!
Qikelela ukuba nawe unomdla koku: Unganciphisa njani okanye uthintele i-thermal demagnetization kunye ne-oxidation ye-iron boron, ekhokelela ekunciphiseni ukunyanzeliswa?
Impendulo: Le yingxaki nge-thermal demagnetization.Ngokwenene kunzima ukulawula.Nika ingqalelo kulawulo lobushushu, ixesha kunye nesidanga se-vacuum ngexesha le-demagnetization.
Kukweliphi ixesha apho umazibuthe we-iron-boron uya kungcangcazela aze angabi namagnethi?
Imagnethi yemagnethi esisigxina ayizukwenziwa demagnetic ngenxa yokungcangcazela rhoqo, kwaye i-high-speed motor ayizukwenziwa demagnetic naxa isantya sifikelela kuma-60,000 rpm.
Lo mxholo wemagnethi ungasentla uqulunqwe kwaye kwabelwana ngawo yiHangzhou Magnet Power Technology Co., Ltd. Ukuba unayo nayiphi na eminye imibuzo yemagnethi, nceda uzive ukhululekilejongana nenkonzo yabathengi kwi-intanethi!
