What Are The Requirements For Magnetic Powder Used In Magnetic Powder Clutches?

Magnetic powder is applied to magnetic powder clutch and magnetic powder brake. It has high magnetic induction, high magnetic permeability, low remanence, low coercive force, high Curie point and large transmission torque. And has good heat resistance, wear resistance, thermal conductivity and chemical stability. It can be well matched with magnetic powder clutch and magnetic powder brake. It can still maintain smooth and non-corrosive points after use, without damaging the magnetic powder clutch and magnetic powder brake. Commonly used magnetic powders are oxide magnetic powder and metal magnetic powder.

       Magnetic powder clutch is mainly used in the fields of printing and papermaking machinery, food machinery, packaging industry and textile industry in the fields of military industry and civil use. Magnetic powder has great influence on the properties of magnetic recording materials.

Therefore, there are certain requirements for magnetic powder:

1 is larger than the saturation magnetization σs and the coercive force Hc;
2 the particles are finely needled and uniform;
3 has high dispersibility and filling in the magnetic slurry;
4 magnetic stability.

        It is difficult for the magnetic powder to satisfy the above requirements at the same time. It can be seen that in daily work, it is necessary to select high-quality products with the performance standards of regular manufacturers to make our magnetic powder clutch use better!
