摘要
对以羰基铁粉、硅油和烃类油为悬浮相和悬浮介质 ,通过适当添加剂和工艺制备的磁流变体材料 ,制备方法、磁流变性能及影响因素进行了研究 ,认为是具有良好综合性能的磁流变体材料。制备的磁流变体具有较低的零场粘度 (0 .4 1.5Pas) ,较高的剪切应力 (τ =5 0 75kPa)
A relatively stable and redispersible MR fluids based on meso-scale ferromagnetic carbonyl iron (CI) powder, silicone oil or hydrocarbon oil and suitable additives by rational process is described. The MR fluid exhibited shear stresses of 75 kPa (B-0.6 T), off state viscosity of 0.41.5 Pa s, and ideal damping property.
