Fluid Magnetic - amanzi phezulu

fluid Magnetic - esisodwa ummangaliso eyenziwe ngumntu, ukudalwa inkqubela zobugcisa neengcinga zenzululwazi zenkulungwane yamashumi amabini. Mu kuya kwa nshita uninzi lwezinto buchopho babantu, iziyobisi kulwelo, ngempahla eyomeleleyo owahluke ngokwemvelo, akanayo analogue ngokwesimo. Ngophuhliso okukhawulezileyo kobugcisa, kukho uphawu ixesha lethu, izinto ngempahla engaqhelekanga ezinjalo izicelo ngaphezulu.

fluid Magnetic i ukunqunyanyiswa entle, ngamanye amazwi, isisombululo colloidal of material ferromagnetic kwindawo eliphakathi eqhelekileyo engamanzi banakho ukuba amanzi eziqhelekileyo, kunye hydrocarbon, kunye lesilicon okanye izinto organofluorine. Kwakukho enjalo into engaqhelekanga ixesha elide. Emva phaya kwiminyaka yee-gqira ukuba kuhlelwe eUnited States eSoviet Union phantse ngaxeshanye.

Nangona kulwelo magnethi esetyenziswa kwiinkqubo ezahlukeneyo space, apho kwamagunya amakhulu amabini kuqhutywa ngokuzimisela. Uluhlu olubanzi zoluntu lwezenzululwazi ezi izinto ezingaqhelekanga baye kufumaneka kutshanje. Ngoku fluid magnetic uye wafunda kabanzi yamazwe aphuhlileyo kunye owodwa lwezenzululwazi: Japan, France, Jamani, Great Britain kunye nabanye.

Ezi into isimanga unique indibanisela yawo ebalaseleyo amandla aphezulu isivuno kunye iimpawu ezingaqhelekanga owahluke ngokwemvelo, apho amashumi amawaka imiyalelo sezingeni ubemde ulwelo ezaziwayo. Le elifihlakeleyo magnetization kakhulu kwizinto ferromagnetic saa ukuya ubukhulu hayi ngaphezulu neenanometer ezilishumi, kunye nokuqaliswa agcina sibe lulwelo medium eqhelekileyo.

Ngoko ke, into kunye fluidity obuncamisileyo ekuqaleni lizele inani nanto ezincinane enamandla umazibuthe esisigxina imilo ukulenza. nanoparticle ngasinye isale umboniso olukhuselayo-repellant ethintela ukuba ukuhlala ndawonye. Le isindululo thermal ye iimagnethi ezincinane isasaze kuyo umthamo iziyobisi, ngaloo ndlela uphepha ukulungisa amasuntswana ukuya ezantsi. Ngenxa yoko, le ulwelo magnetic uyakwazi ukugcina umgangatho engaqhelekanga kunye nokwenziwa iminyaka emininzi.

umazibuthe nganye ezincane ngokungakhethiyo atyhutyhela kwi ulwelo phantsi kwempembelelo ubushushu. I yangaphandle zibuthe ngendlela ethile ojolise zihlandlo kazibuthe le microparticles, nto leyo ebangela utshintsho izinto zobumnini woqondo, rheological kunye kazibuthe sisombululo colloidal. Ngenxa yoko, izinga eliphezulu Uvakalelo oluludaka ukuya engaphandle ngemagnethi umthombo endle inikeza ikhono ukunyenyisa ukuziphatha kwabo. Ngoko ke, lo controllability kwaye ofumana ulwelo magnetic ngokwayo, ukusetyenziswa apho iba kunokwenzeka ukuba kubekho iintlobo ezininzi izicelo.

ukumiswa Ferromagnetic sele ezisetyenziswa xa kusenziwa disks nzima, apho isicelo kwizikhondo olujikelezayo ukuthintela ukungena nto amazwe ezivela ngaphandle. zokumiswa ezifana nazo ezisetyenziswa xa kusenziwa abathetha eliphezulu rhoqo kwi aerospace kunye nabammeli kwezoshishino, optic amayeza, elektroniki kunye noshishino isixhobo izigqibo.
