Description
(54) СПОС.ОБ ПОЛУЧЕНИЯ ФЕГРОМАГИИТНОЙ ЖИДКОСТИ(54) METHOD OF OBTAINING FEGOMAGIETIC LIQUID
галлий с добавлением к полученной дисперсии железа раствора органической несущей жидкости, содержащей поверхностно-актдвные вещества. Дальнейший помол ведут до полной пептизадин полу енного высокоднсперсного порошка.gallium with the addition to the resulting dispersion of iron solution of an organic carrier fluid containing surface-active substances. Further grinding is carried out to the full peptizadin of the obtained highly dispersed powder.
При этом используетс влерше oxpyiiчиаани железа под действием расплава индий-галлий, что позвол ет диспергировать с помощью механического дроблени такой пластичный материал как железо, обладающее высокой намагниченностью насыщени .In this case, a blistering of oxpy iron removal under the action of an indium-gallium melt is used, which makes it possible to disperse such plastic material as iron, which has a high saturation magnetization, by means of mechanical crushing.
Смесь из 4О г восстановленЕГого реактивного железа в порошкообразном состо нии и 3 г раствора инднй-галлий (в процентном отношеню соответствующем эвтектике) загружают в хромированную камеру коллоидной мельницы. Дробление производ т в течение 40 ч. Затем в камеру заливают 1ОО мл керосина, содержащего О;1% олеиновой кислоты и 5%A mixture of 4O g of reduced reactive iron in a powdered state and 3 g of an inn-gallium solution (as a percentage of the corresponding eutectic) are loaded into a chrome-plated chamber of a colloid mill. The crushing is carried out for 40 hours. Then, 1OO ml of kerosene containing 0; 1% oleic acid and 5% is poured into the chamber.
по весу каучука СНСМ-30, и продолжаю помол в течение ЮО ч. Полученную ФМЖ отбирают из камеры и центрифугируют 2 ч при ускорении 45ОО д.according to the weight of the SNSM-30 rubber, and continue to grind for 100 hours. The obtained FMF is taken from the chamber and centrifuged for 2 hours at an acceleration of 45 ° d.
Предлш аемый способ позвол ет значительно снизить трудоемкость процесса помола за счет сокращени длительности процесса ( 14О ч длитс процесс в предлагаемом способе, больше 1ООО часов в известном), таким образом, длительность процесса снижаетс в 7 раз.The proposed method allows to significantly reduce the laboriousness of the grinding process by reducing the duration of the process (14Oh hours the process in the proposed method, more than 1OOO hours in the known), thus, the process duration is reduced by 7 times.
Представл етс возможность в качестве исходного материала дл получени ФМЖ npj-iN-ieHHTb широко распространенное и дешевое железо с высоким значением намагниченности насыщени , вместо ферритов, намагниченность насьпцени которых ниже, а также улучшаютс параметры ФМЖ.It is possible to use widespread and cheap iron with a high saturation magnetization value, instead of ferrite, below, as well as improving the FMF parameters as a starting material for obtaining the fPG npj-iN-ieHHTb.
В таблице представлены параметры ферромагнитной жидкости.The table presents the parameters of the ferromagnetic fluid.
