Application of NdFeB Magnets in Industrial Production

2023-12-18

Magnets have always been widely used, and as time progresses, the use of magnets has become more and more significant, and many products will involve magnets. Iron boron strong magnets have the characteristics of small size, light weight and strong magnetic properties, and are the magnets with the best function and price ratio so far. The main raw materials for the production of NdFeB magnets are neodymium metal, pure iron, ferroboron alloys and other additives. While magnets bring us convenience, they will also have certain hazards. For example, electronic products such as credit cards and keyboards will be magnetized by magnets.

As the latest development of rare earth permanent magnet materials, NdFeB magnets are called "Magnetic King" because of their excellent magnetic properties.

In the descaling and anti-scaling industry of NdFeB magnets, after the water is treated with NdFeB high-strength magnetization, the water molecular bonds are deformed in angle and length at the same time, and the hydrogen bond angle is reduced from 105 degrees to about 103 degrees, which makes the physical The chemical properties have undergone a series of changes, and the activity and solubility of water have been greatly improved. Calcium carbonate in the water is decomposed into a relatively soft calcium bicarbonate during the cooking process, which is not easy to accumulate on the wall and is easily taken away by water. In addition, the degree of polymerization of water increases, and the dissolved solid matter becomes finer particles. After the particles are refined, the distance between the two ions is smaller, and it is not easy to condense on the wall, and then achieve the effect of descaling.

The environmental protection and energy saving of NdFeB magnets is becoming an important factor affecting the development of manufacturing industries in various countries, and NdFeB is one of the primary raw materials for the production of environmentally friendly and energy-saving products. For example, the use of NdFeB in cars, compressors, wind turbines and other fields is just for the consideration of environmental protection and energy saving. As a functional material for environmental protection and energy saving, NdFeB will be used more and more widely.

NdFeB magnets are used in the health care profession. A large number of practice and scientific experiments have confirmed that the high-strength magnetization of NdFeB can change the physical properties of water such as surface tension, density, and solubility, and have a serious impact on chemical properties such as acid and alkali. Magnetized water can be added The activity of enzymes in water and the permeability of biofilms can be used to strengthen health, regulate the microcirculation system, digestive system, endocrine system and nervous function of the human body, improve human immunity, prevent and treat various diseases.

As the third-generation rare earth permanent magnet material, NdFeB magnets have high performance and are widely used. However, it should be noted that in order to avoid the harm of corrosion, it is necessary to maintain the surface of NdFeB magnets during use, such as using gold , zinc, etc. for electroplating, and epoxy resin spraying on the surface.
