Neodymium magnetic materials, as the latest result of the development of rare earth permanent magnets, are known as the “King of Magnets” because of their excellent magnetic properties. Neodymium high-strength magnet has the characteristics of small size, lightweight and strong magnetism. It is the best magnet with the best performance-price ratio so far. The main materials for producing NdFeB high-strength magnets are neodymium metal, pure iron, ferroboron alloy, and other additives.
NdFeB magnet has been proved by many practices and scientific experiments in the field of disease elimination and health care that Nd-Fe-B magnetization can change the physical properties of water such as surface tension, density, and solubility, and has a significant impact on the chemical properties such as acid and alkali. Magnetized water can increase the activity of enzymes and permeability of biofilm in water, strengthen health care by drinking regularly, and regulate the micro-circulatory system, digestive system and internal system of the human body. Secretory system and nerve function, improve human immunity, prevent and treat a variety of diseases.
Neodymium arc magnet is used in scale removal and scale prevention industry. When water is treated by Nd-Fe-B high-intensity magnetization, the angle and length of water molecular bond deform simultaneously. The hydrogen bond angle decreases from 105 degrees to 103 degrees, resulting in a series of changes in the physical and chemical properties of water. The activity and solubility of water are greatly improved.
Calcium carbonate in water is decomposed into lower soft calcium bicarbonate during cooking, which is not easy to be found. It is easy to be carried away by water when it accumulates on the wall. In addition, with the increase of the degree of polymerization of water, the dissolved solid material becomes finer particles. When the particles are refined, the distance between the two ions is smaller, and it is not easy to condense on the wall, thus achieving the effect of scale removal.
Environmental protection and energy saving of Nd-Fe-B magnets are becoming an important factor affecting the development of manufacturing industries in various countries, and neodymium magnets are one of the main raw materials for manufacturing environmental protection and energy saving products. For example, the application of NdFeB in automobiles, compressors, wind turbines and other fields is due to the consideration of environmental protection and energy saving.
Nd-Fe-B, as a functional material for environmental protection and energy saving, will be more widely used. In an era of an increasing energy shortage, the conversion of wind energy into electricity will undoubtedly be supported by government policies. Wind power generation has been implemented on a large scale in Europe. The previous 1 MW units used about 1-ton rare earth magnets. Thanks to the rapid growth of the wind power industry, the consumption of NdFeB in wind power generating units will also increase rapidly.
