Magnetic fluid is a new type of functional material that exists in liquid form as a magnetic conductive material. It is a stable liquid formed by uniformly dispersing magnetic solid particles with a diameter of 10 nanometers into a base carrier liquid, which has both liquid fluidity and good magnetic conductivity. According to the different base carriers, they can be divided into ester based, water-based, silicone based, etc.
Magnetic fluid seal
The principle of magnetic fluid sealing:Magnetic fluid sealing technology is achieved by utilizing the excellent response characteristics of magnetic fluids to magnetic fields. When injecting magnetic fluid into the gap of the magnetic circuit composed of high-performance permanent magnets, magnetic shoes with good magnetic conductivity, and a rotating shaft, under the action of the magnetic field, the magnetic fluid forms several liquid "O" rings in the gap, thus playing a sealing role.
