Magneto Rheological

The hydrophilic-lipophilic balance (HLB) parameters of surfactants have a significant effect on properties of surfactants and determine the effects of surfactants. The magneto-rheological fluid (MRF) is prepared by using the two typical HLB parameters of surfactants including Polyethylene Glycol and oleic acid in order to improve the property of MRF. Polyethylene Glycol (PEG) whose HLB parameter is 20 has strong hydrophilic. Oleic acid whose HLB parameter is 1 has strong lipophilic. The results indicate that magnetic properties of magnetic particles and rheological properties of MRF can hardly be changed by adding surfactants. The sedimentary stability of MRF adding lipophilic surfactants is superior to that of MRF adding hydrophilic surfactants, and the stability of MRF adding two surfactants increases significantly.

Magneto Rheological

This research work is concerned with synthesis of an innovative type of magneto-rheological fluid (MRFluid) using edible low-cost soya bean oil as a carrier liquid with three different concentrations of electrolytic iron powder as a suspended medium and additives as a commercial grease. The field-dependent rheological properties of MRFluid samples were tested under different magnetic field conditions using rheometer. The results of the field-dependent-rheological properties of the prepared MRFluid samples show good agreement with commercial MRFluid. This directly indicates that the proposed innovative type of MRFluid can be used in automotive suspension systems, dampers, vibration control devices and so forth. Sedimentation test is also carried out in order to know the stability of the MRFluids.

High Temperature Environment

Nanometer calcium carbonate (nano-CaCO3) is an inorganic material that does not have the rheological properties of a magneto-rheological fluid (MRF) but has some effects on the sedimentary stability and rheological properties of MRF. The MRF was prepared by adding nano-CaCO3 to improve its comprehensive and practical properties. The results showed that, with an increase in the amount of nano-CaCO3, the sedimentary stability of MRF would be improved. The off-state viscosity of MRFs increased with an increasing amount of nano-CaCO3. The shear stress of MRF was decreased slightly by adding nano-CaCO3. To some extent, the comprehensive and practical properties can be improved by adding a certain amount of nano-CaCO3. However, there is also certain localization that properties of MRF are improved by adding Nano-Inorganic Materials in the high temperature environment.
