Innovative synthesis technology : Si raw materials are vaporized as passing through a high-temperature plasma zone, and the supersaturated Si gas precipitates high-purity nano powders of desired size in a cooling zone.
Technology that implements composites with controlled properties through optimized innovative process, based on analysis of characteristics and properties of precursor.
Magnetorheological Fluid (MRF) is an advanced smart material that revolutionizes the way we control vibration, shock, and motion.
MRF is a special fluid whose viscosity (flow resistance) changes instantly when exposed to an external magnetic field. When a magnetic field is applied, the micro-sized or nano-scale magnetic particles inside the fluid align, transforming the fluid into a semi-solid state. And when the magnetic field is removed, the fluid returns to its liquid state. This transformation is completely reversible, allowing real-time control of mechanical properties such as stiffness and damping. Because of these unique properties, MRF can effectively control external shocks and vibrations in real time, and is widely used in various fields such as vehicle suspension systems, vibration control in building structures, and shock absorption in industrial machinery.
MRF operates inValve ModeandShear Mode, controlling the movement of the fluid depending on the strength of the magnetic field:
When the fluid flows through a narrow passage (orifice), applying a magnetic field increases the flow resistance of the fluid, thereby adjusting the damping force.
When the fluid experiences shear forces between two surfaces, applying a magnetic field increases its viscosity, resulting in higher shear resistance.
In conclusion, MRFs can precisely adjust viscosity based on the strength of the magnetic field, which provides MRFs with a smart technology that absorbs shock and vibration and effectively controls movement.
