水基磁流变液的制备及其性能研究

Preparation and properties of water-based magnetorheological fluid

以经过表面处理的微米级羰基铁粉、亚微米级四氧化三铁粉末为悬浮相,去离子水为悬浮介质,加入适当的添加剂,通过一定的工艺制备出综合性能良好的水基磁流变液。研究了几种含有不同悬浮相粒子和不同添加剂的磁流变液的剪切性能和沉降稳定性能,分析了悬浮相的组成对磁流变液磁流变性能的影响以及添加剂对改善磁流变液抗沉降团聚稳定性的作用。

The preparation of water-based magnetorheological tluld is introduced. It＇s compositions comprise surface-treated micron carbonyl iron particles, Fe3O4 particles, de-ionized （DI） water and suitable additives. It＇ s properties of dynamics shear stress and sendimentation stability is measured. The effect of particles composition and additives on the MR fluid rheological characteristics and sendimentation stability is studied too.
