How to prevent strong neodymium magnets from absorbing moisture
Strong neodymium magnets, also called neodymium iron boron magnets, are tetragonal crystal structure crystals produced by neodymium, iron, and boron (Nd2Fe14B). Today, I will discuss with you how to prevent strong neodymium magnets from absorbing moisture.
How to prevent strong neodymium magnets from absorbing moisture? Strong neodymium magnets, also called neodymium iron boron magnets, are tetragonal crystal structure crystals produced by neodymium, iron, and boron (Nd2Fe14B). Today, I will discuss with you how to prevent strong neodymium magnets from absorbing moisture.
1. Electroplating principle: The electroplating process of nickel (Ni), zinc (Zn), gold (Au), chromium (Cr), epoxy resin (Epoxy), etc. can be used for strong neodymium magnets. NdFeB surface passivation agent, blocking rust and causing spots, main ingredients: metal material surface passivation agent, deposition agent, surface active agent, buffering agent, polymerization agent, etc.` The samarium cobalt magnet and neodymium iron boron are electroplated with nickel. The surface is shiny when viewed macroscopically, but it is fragmented when observed with a microscope. Therefore, moisture can still penetrate into the interior, oxidizing the air of the strong neodymium magnets, and reducing the magnetic energy of the strong neodymium magnets.
2. Coating method: Generally, strong neodymium magnets are coated with some organic chemical epoxy resin, thermal grease or some insulating layer waterproof board. Because the coating material must be equipped with an organic solvent to be coated, the organic solvent has to evaporate, leaving many holes in the coating layer. Some coating materials are inherently water-absorbent. After a long period of time, water penetrates in, causing the strong neodymium magnets to absorb moisture and oxidize in the damp air, reducing its function.
3. The common problems of storing strong neodymium magnets do not need to be close to the electronic equipment. If it is close enough, it will harm the electronic products and the control circuit and directly affect the application.
4. It is not necessary to store it in damp and cold conditions to prevent air oxidation of strong neodymium magnets, which may cause changes in appearance, physical properties and magnetic energy.
5. It is not necessary to bring strong neodymium magnets close to hard disks, disk drives, overdraft cards, audio tapes, savings cards, television picture tubes, etc. If you get close to components such as magnetic monitoring software, it will harm or even destroy the recorded data information.
6. If a person who has a sensitive reaction to alloy objects approaches strong neodymium magnets, the skin will not be smooth and red. If the above reaction occurs, please do not touch the strong neodymium magnets.
