Are NdFeB magnets used in daily life and industry?

Neodymium iron boron magnet material, as a new result of the development of rare earth permanent magnet material, is called "magnetic king" because of its excellent magnetic properties. The iron boron strong magnet has the characteristics of small volume, light weight and strong magnetism, so far it is a magnet with good performance and price. The main raw materials for producing neodymium iron boron strong magnet are metal neodymium, pure iron, ferroboron alloy and other additives.


In the field of disease elimination and health care, a large number of practical and scientific experiments have proved that the high-strength magnetization of NdFeB can change the physical properties of water, such as surface tension, density, solubility, and has a significant impact on the chemical properties of acid and alkali. The magnetized water can increase the activity of enzyme in water and the permeability of biofilm. Regular drinking can strengthen health care, regulate the microcirculation system, digestive system, and inner part of human body Secretion system and nerve function, improve human immunity, prevent and treat various diseases.


In the descaling and antiscaling industry, after the high-strength magnetization treatment of neodymium iron boron, the angle and length of water molecular bond deform at the same time, and the hydrogen bond angle reduces from 105 ° to 103 ° or so, which makes the physical and chemical properties of water change in a series, and the activity and solubility of water increase greatly. The calcium carbonate in water decomposes in the cooking process to produce low soft calcium bicarbonate, which is not easy to be found in the cooking process It is easy to be taken away by water.


In addition, the polymerization degree of the external water is improved, and the dissolved solid matter becomes finer particles. After the particles are refined, the distance between the two ions is smaller, which is not easy to condense on the wall, so as to achieve the effect of descaling.


Environmental protection and energy saving of NdFeB magnets are becoming an important factor affecting the development of manufacturing industry in various countries, and NdFeB is one of the main raw materials for manufacturing environmental protection and energy saving products. For example, the application of NdFeB in automobile, compressor, wind turbine and other fields is just for the consideration of environmental protection and energy saving. Neodymium iron boron, as a functional material for environmental protection and energy conservation, will be widely used.


In the era of increasingly energy shortage, the transformation of wind energy into electric energy will undoubtedly be supported by government policies. At present, wind power generation has been implemented on a large scale in Europe. The former 1 megawatt units use about 1 ton of NdFeB. Thanks to the rapid growth of wind power industry, the consumption of NdFeB in wind power generation units will also increase rapidly.
