MRF
MRF (Magnetorheological Fluid) for short, is a suspension composed of micron, submicron and nano-sized soft magnetic particles dispersed in a mother liquid. It is a smart material whose rheological properties will change significantly under the action of an external magnetic field. . Under the condition that no magnetic field is applied, the MRF exhibits characteristics similar to Newtonian fluid; under the condition that the external magnetic field is applied, the magnetic particles in the MRF are arranged in order in the direction of the magnetic field lines in the base carrier liquid, hindering the flow of the liquid, showing Herschel /Buckley Fluid Properties. Using the rheological properties of MRF, it is combined with machinery and control systems to make magnetorheological shock absorbers, which can be widely used in the vibration and impact control of vehicles, aircraft, buildings and bridges. MRF can also be used in vehicle clutches, brakes, material surface polishing and other fields. |
SmartFluid ® Product Features
-
Low zero field viscosity
It has a very low viscosity under the condition of zero magnetic field, which is beneficial for the actuator to obtain the lower limit of the regulating force value as low as possible.
-
High yield strength
Under the action of an external magnetic field, it has a high yield strength, which is beneficial to the actuator to obtain the upper limit of the adjustment force value as high as possible.
-
Good wide temperature
It can be used normally for a long time in the range of -45℃-130℃.
-
Good settlement resistance
The settling rate is low after standing for a long time, and no hard settling occurs.
-
Good redispersibility:
It is very easy to redisperse uniformly after prolonged standing and settling.
-
Good thickening resistance
No IUT (use thickening) phenomenon occurs after long-term use.
-
Good anti-aging properties
Long-term use is not easy to cause aging due to factors such as oxidation, temperature, light, and mechanical force.
-
Good liquidity
It has excellent fluidity after the external magnetic field is removed.
-
Good sealing compatibility
Using special materials and formulas, it has good compatibility with sealing materials, which is beneficial to ensure the reliability of sealing.
-
Good friction reduction
The friction coefficient with the contact surface is low, which is beneficial to improve the mechanical performance of the actuator.
-
Good abrasion resistance
Long-term use has little effect on contact surface wear, which is beneficial to improve the durability of the actuator.
-
Green:
It is prepared with environmentally friendly materials and environmentally friendly processes, and is environmentally friendly.
Instructions
It is normal for MR fluids to delaminate to some extent after standing for a period of time. It should be fully stirred before use to make the magnetorheological fluid return to a uniform state before use.
Storage method
Store tightly closed at room temperature.
