| titleOfInvention | Method for producing magnetic fluid of ultra fine F-CIO powder |
| abstract | In the present invention, the ultra-fine Fe-Co powder having the largest saturation magnetization, which is a measure of the performance of a magnetic fluid, has a diameter of 5-15 μ, and the Si, Cr, Ti, Ca, Al, The magnetic fluid of the present invention is prepared by coating Mg and Mn oxides with a thickness of 0.01-3 μm and then coating a hydrocarbon-based surfactant and dispersing them in an oil- or non-volatile hydrophilic liquid phase to produce a new high-performance magnetic fluid. Compared with the iron oxide magnetic fluid, the saturation magnetization is increased by 2.5 times or more, there is no deterioration, there is no pollution when used, and the pressure resistance is 1,000-20,000 g / ㎠ in terms of performance, which is 10-200 times higher than the conventional magnetic fluid. From automobiles, ships, various automation machines, and automatic pumps that could not be used as magnetic fluids, the drive shaft sealing device of pressure resistance can be widely used. |
