Ferrofluid

Ngo nineties ekuqaleni kwekhulu yeta movie "Terminator 2" kwi cinema zesikrini. Zonke izibukeli bahlatshwa umxhwele ikhono cyborg killer ductile metal, eyadlalwa Robert Patrick, thatha ezihlukahlukene guises.

Khona-ke, bencoma efanele wenza ikhompyutha izithombe, thina ungacabangi mayelana lokuthi umphumela kuhle kugucuka cyborg-killer kungenziwa eyenziwe ezimweni bomhlaba wangempela.

Ferrofluid - lena impahla esikuvumela ubone izinto eziqoshwe ngamathambo ezindlovu ezihambayo. Ngu the classic kazibuthe kungenziwa ukhangwa noma wacasulwa zonke izinto. Kodwa ukusabela iningi labo ibuthakathaka ukuze kuphela itholwe mishini ekhethekile. Bekungaba kuhle uma kungase kwandise izakhiwo magnetic izinto ngaphandle kokubhubhisa isakhiwo sabo futhi ushintsho oluphawulekayo ezakhiweni zabo kokuqala.

Konke kwashintsha lapho isixazululo sale nkinga liphazamisa osokhemisi wadala uketshezi ferromagnetic, kokuba flowability ezinhle. Bakwazi ukuthola izinhlayiya ezincane kunazo kazibuthe lapho kwangena woketshezi, lapho zihlatshwa kazibuthe musa aziphatha ibhola is hhayi ixazululwe, futhi uketshezi wenza "okuqinile".

uketshezi Ferromagnetic - a ukuhlakazwa colloidal ka ferrites, izinto ferromagnetic izinhlayiya ezincane kakhulu sisimamiswe i osebenzelana aqueous noma hydrocarbon, ngokusekelwa ngaphandle izinto asebenzayo. uketshezi ezinjalo esitebeleni iminyaka eminingi futhi kanjalo aye a flowability ezinhle kuhlangene uzibuthe izakhiwo.

uketshezi Ferromagnetic ingatholakala ngezindlela eziningi. Inqubo oluphakeme elula unezigaba ezimbili. Ekuqaleni, kwadingeka sithole ama-izinhlayiya magnetic nge Ubukhulu eduze Colloid. Futhi mina nginaso nakakhulu - ekulinganiseni nabo base ketshezi.

Kakhulu isihloko esifanele kubacwaningi ukuthi kungenzeka ukusebenza okungokoqobo kwezimiso uketshezi ezinjalo. Eminyakeni yamuva, besebenza amanzi angcolile uhlanzekile uketshezi ezifana uwoyela. Isimiso yale nqubo - the magnetization lamafutha nge-isingeniso eziwuketshezi magnetic anokungcola. Bese uwoyela uzibuthe zihlukaniswe izinhlelo ezikhethekile.

uketshezi Ferromagnetic uthola isebenza imithi. Ngokwesibonelo, izidakamizwa anticancer ukulimaza amaseli enempilo. Kodwa uma umshanguzo ketshezi futhi ogulayo egazini futhi isimila ukuletha uzibuthe, bese le ngxube bagxila endaweni efanele hhayi umzimba wonke ubuhlungu.

Futhi nakhu esinye isibonelo. Izinkampani esikhiqiza racing izimoto, amabhampa yabo wathela ferrofluid. Yehlulekile kubo electromagnet kweso kwenza uketshezi liquid noma viscous. Ngakho, ukumiswa imoto kushintshwe.

Have uketshezi okunjalo futhi izakhiwo ukwazi. Uma uphuthelwe igagasi umsindo ngokusebenzisa uketshezi uzibuthe, e Yikhoyili exhasa, elise eduze kagesi ukushayela force. Futhi omunye. Uma isixazululo Bubbles engeza uketshezi kazibuthe, uthola umbono othakazelisayo.
