双酯基磁性流体的制备及加热时间对磁性流体性能的影响

Preparation of diester magnetic fluid and effect of heating time on magnetic fluid properties

酯基磁性流体是动密封最常用的密封用磁性流体,用共沉淀法制备Fe3O4磁粉,并以双酯基合成油为制备载液磁性流体,同时研究加热时间对酯基磁性流体性能的影响。

Ester- based magnetic fluid is mostly used in motive seal. The Fe304 magnetic was prepared by coprecipitation method. The carrier liquid magnetic fluid was prepared with diester cogasin. The effects of heating time on magnetic fluid properties were studied.
