Maginito madzimadzi - madzi oyenda oposa

Maginito madzimadzi - wopangidwa wapadera chozizwitsa, chilengedwe cha patsogolo luso ndi maganizo sayansi zaka mazana makumi awiri. Mosiyana ndi ambiri zoyambitsidwa za namatetule anthu, ngati chinthu madzi, ndi katundu amphamvu maginito, alibe analogues mu chikhalidwe. Ndi kukula mofulumira luso, khalidwe nthawi, zinthu ndi katundu ngati zachilendo ndi ntchito zambiri.

Maginito madzimadzi ndi kuyimitsidwa chabwino, mwa kulankhula kwina, njira colloidal wa zinthu ferromagnetic mu ochiritsira madzi sing'anga omwe angathenso madzi wamba, chimasanduka, ndi pakachitsulo kapena zinthu organofluorine. Panali ngati zachilendo mankhwala kwa nthawi yaitali. Back m'ma zaka zao za sikisite iwo apanga mu United States ndi Soviet Union pafupifupi imodzi.

Ngakhale madzimadzi maginito ntchito mu ntchito zosiyanasiyana malo, zomwe mayiko ankachititsa intensively. A osiyanasiyana onse a asayansi zinthu ovuta akhala akupezeka posachedwapa. Tsopano madzimadzi maginito wakhala anaphunzira kwambiri m'mayiko ambiri otukuka ndi kuthekera mkulu sayansi: Japan, France, Germany, Great Britain ndi ena.

Izi mankhwala zodabwitsa wapadera osakaniza ake chabwino cha mphamvu mkulu zokolola ndi maginito katundu imachita, limene zikwizikwi malamulo zoopsa kuposa aliyense wa madzi ndi odziwika. Chinsinsi ndi magnetization phenomenal mu zipangizo ferromagnetic omwazika ndi kukula si choposa nanometers khumi, ndi oyamba anayamba mu madzi sing'anga wamba.

Choncho, chinthu ndi fluidity kwambiri poyamba zimalimbikitsa sangaganize chiwerengero cha mphamvu kakang'ono okhazikika maginito ozungulira mawonekedwe. Aliyense nanoparticle TACHIMATA zoteteza-othawitsira filimu kuti zimawalepheretsa kusagwirizana. Chisonyezo matenthedwe a maginito yaing'ono kugawira mu buku la mankhwala, potero amapeŵa Kuthetsa particles pansi. Chifukwa, madzimadzi maginito akhoza kukhala wapadera zake khalidwe ndi ntchito kwa zaka zambiri.

Aliyense maginito tosaoneka mosintha amazungulira mu madzi mchikakamizo cha kutentha. Kunja maginito m'njira zina zochokera mphindi maginito ya microparticles, amene amachititsa kusintha mu kuwala, rheological ndi maginito katundu wa njira colloidal. Choncho, mkulu mlingo wa tilinazo wa slurry kwa akunja maginito gwero munda amapereka mphamvu kusintha makhalidwe awo. Choncho, controllability ndipo amapeza madzimadzi maginito yokha, ntchito imene imatheka chifukwa osiyanasiyana ofunsira.

Ferromagnetic kuyimitsidwa kale ntchito kupanga mbale zovuta, kumene chagwiritsidwa kutsinde onsewo kuteteza ingress wa nkhani yachilendo kunja. suspensions amenewa amagwiritsidwa ntchito mu kupanga okamba mkulu-pafupipafupi mu Azamlengalenga ndi chitetezo makampani, Optics ndi mankhwala, zamagetsi ndi makampani chida kupanga.
