Magnetic Urume - mvura mudenga inoyerera

Magnetic Urume - rakasiyana chishamiso nevanhu, zvisikwa unyanzvi mberi uye pfungwa yesayenzi remakore rechimakumi maviri. Kusiyana vakawanda zvigadzirwa ose shasha kwevanhu, akadaro mvura fuma, pamwe simba rinonzi magnetic ehupfumi, haana analogues ari mamiriro. With kukurumidza kukura zvigadzirwa, anozivikanwa nguva yedu, zvinhu kujairwa ehupfumi zvakadaro zvakawanda mafomu.

Magnetic Urume iri kuturika yakaisvonaka, mune mamwe mazwi, munhu colloidal mhinduro ine ferromagnetic zvinhu nenzira kwakajairika mvura svikiro ringaita dzinoshandiswawo misi mvura, uye Mahydrocarbon, nesilicon kana organofluorine zvinhu. Paiva fuma kujairika zvakadaro kwenguva refu. Kare nemakore sixties vakanga synthesized muUnited States uye Soviet Union anenge panguva imwe chete.

Nepo rinobva mvura inoshandiswa nzvimbo dzakasiyana-siyana zvirongwa, iyo nyika mbiri dzine inoitwa kuzviita. A rakasiyana-siyana munharaunda yesayenzi izvi kujairika zvinhu vava kuwanika ichangopfuura. Zvino rinobva mvura kwave akadzidza zvikuru kupfuura dzakabudirira dzakakwirira nesayenzi zvinogona: Japan, France, Germany, Great Britain nevamwe.

Izvi zvinoshamisa fuma rakasiyana yaro kunoshamisa wemishonga yakakwirira goho simba pamwe aakatipa rinobva ehupfumi, iro makumi ezviuru mirairo unokosha kupfuura chero anozivikanwa zvinwiwa. Chakavanzika chinhu tisaone magnetization mu ferromagnetic zvinhu vakapararira kune imwe saizi isingadariki nanometers gumi, uye unozotevera sumo yavo ive munhuwo zvokunwa svikiro.

Saka, imwe pfuma yakanaka fluidity iri pakutanga yakazara sanzwisisika uwandu simba vakasiyana zvachose magineti idenderedzwa chimiro. Mumwe nanoparticle zvinenge zvakazara anodzivirira-repellant firimu kuti kunotadzisa kubva akanamatira pamwe chete. The chafariz inofamba pakati magnets a duku anovapavhurira yose Vhoriyamu fuma, nokudaro angasafa nyaya zvacho kusvikira pasi. Somugumisiro, mashoko rinobva mvura anokwanisa kuramba rakasiyana unhu yayo uye waivako kwemakore akawanda.

Mumwe nemaziso magineti randomly circulates iri mvura pasi pokudzora nokupisa. The kwokunze remagineti mune imwe nzira nezvatinovavarira rinobva nguva yacho microparticles, izvo chinoita kuchinja Manyiminya, rheological uye rinobva zvivako zviri colloidal zvichachipedza. Somugumisiro, mumwe mukuru azvipire nehanya of slurry kuchivanze remagineti panobva chinopa kukwanisa kuchinja maitiro avo. Nokudaro, controllability uye anowana kuti rinobva mvura pacharo, kushandiswa izvo zvinova zvinoita kuti munhu-siyana mafomu.

Ferromagnetic kuturika atoshandisa ari zvaAtemisi dzakaoma disks, apo vari kureva kutenderera mugodhi kudzivisa ingress vemamwe nyaya kubva kunze. suspensions kwakadaro dziri kushandiswa kugadzirwa mukuru-kakawanda vakurukuri ari Aerospace uye kuzvidzivirira maindasitiri, optics uye mishonga, zvemagetsi uye mudziyo rokuita indasitiri.
