MAGNETO-RHEOLOGICAL FLUID COMPOSITION |
| 摘要 |
Disclosed is a magneto-rheological fluid composition which comprises magnetic particles, a fluid, a dispersant, a structure stabilizer and an anti-friction additive. Particularly, the magnetic particles include non-coated magnetic particles and polyvinyl butyral-coated magnetic particles at the weight ratio of about 1:1 to 4:1. Accordingly, dispersion stability and yield stress are improved substantially when magnetic field is applied to the magneto-rheological fluid. |
