Magnitnye Kolloidy

Magnitnye kolloidy (magnitnye zhidkosti (MZh)), yavlyayushchiesya kolloidami ferri- i ferromagnetikov, do nastoyashchego vremeni privlekayut dostatochno bol'shoe vnimanie kak otechestvennykh, tak i zarubezhnykh uchenykh. Eto svyazano s tem, chto takie namagnichivayushchiesya sredy obladayut tselym ryadom interesnykh svoystv, proyavlyayushchikhsya pri vzaimodeystvii MZh s elektricheskim i magnitnym polyami. Blagodarya etomu, poyavilas' vozmozhnost' ikh primeneniya v mashinostroenii, tekhnike i meditsine. Vzaimodeystvie vysokodispersnykh magnitnykh chastits i proiskhodyashchie v rezul'tate etogo (a takzhe pri vzaimodeystvii s vneshnimi polyami) strukturnye prevrashcheniya vo mnogom opredelyayut fizicheskie svoystva magnitnykh zhidkostey. Osobenno eto aktual'no dlya primenyayushchikhsya na praktike magnitnykh zhidkostey na vyazkikh osnovakh (mineral'nykh maslakh, kremniyorganicheskikh sredakh i dr.). Vliyanie ikh strukturnogo sostoyaniya, obuslovlennogo deystviem vneshnikh poley (elektricheskogo i magnitnogo), na magnitnye svoystva mozhet znachitel'no izmenyat'sya pri dopolnitel'nom deystvii sdvigovykh deformatsiy i techeniy. Eto neobkhodimo uchityvat' pri proektirovanii i prognozirovanii rabotosposobnosti tekhnicheskikh ustroystv.
