How to keep the magnetic stability of Countersunk Cylinder Ring Block NdFeB Magnets in long-term use?

As a high-performance permanent magnetic material, the long-term magnetic stability of Countersunk Cylinder Ring Block NdFeB Magnets is the key to ensure the normal operation of the equipment and extend its service life. In the working and storage environment of the magnet, a high degree of cleanliness should be maintained to avoid the presence of tiny particles such as iron filings and metal powder. These particles may be adsorbed on the surface of the magnet, affecting the uniformity and stability of the magnetic field. Clean the environment regularly to ensure that there is no interference from impurities around the magnet.
Magnets are sensitive to humidity. A humid environment may cause rust on the surface of the magnet, which in turn affects its magnetism. Therefore, ensure that the magnets are stored in a dry and well-ventilated environment. Use dehumidification equipment or desiccant to keep the humidity of the storage environment within a controllable range.
The magnetism of the magnet is greatly affected by temperature. Too high or too low temperature may cause changes in the internal lattice structure of the magnet, thereby affecting its magnetic performance. Store the magnet in a temperature-stable environment to avoid adverse effects of sudden temperature changes on the magnet. Magnets should be stored in special packaging materials to prevent impact and extrusion during transportation and storage. For unplated magnets, a layer of anti-rust oil can be applied on their surface to prevent oxidation and corrosion.
Magnets are brittle materials, and impact and friction may cause changes in their internal lattice structure, which in turn affects magnetism. During installation and use, they should be placed with care and avoid violent impact and friction. Magnetic products should be stored away from items that are sensitive to magnetic fields, such as electronic devices, magnetic recording media, etc. Avoid placing magnets in a strong magnetic field environment to prevent magnetic field interference from causing magnetic instability.
Check the magnets regularly to observe whether there are abnormal conditions such as rust spots and cracks on their surfaces. For problems found, they should be dealt with in a timely manner, such as replacing damaged magnets and cleaning surface dirt. Establish a maintenance file for each magnet, recording its purchase date, use environment, inspection records and other information. According to the use and maintenance records of the magnets, formulate a targeted maintenance plan.
Clean and maintain the magnets regularly to remove dirt and dust on the surface. For magnets used for a long time, magnetic tests should be carried out regularly to ensure that their magnetism is stable. For magnets with weakened or damaged magnetism, they should be replaced in a timely manner. For magnets that cannot be repaired, they should be scrapped in accordance with relevant regulations.
