Rare earth permanent magnet NdFeB and fluid magnetization

Rare earth permanent magnet NdFeB and fluid magnetization

Update Time:2019/5/30
There are many substances in the world that change under the action of a powerful magnetic field. This phenomenon is called "magnetization." Magnetization technology is widely used to magnetize various fluids. The rare earth permanent magnet material NdFeB is the most magnetic permanent magnet material in the world, and its appearance has greatly promoted the development of fluid magnetization processing technology.

Water is our most closely related fluid. It is magnetized into "magnetized water" under the action of a strong magnetic field. A strong magnetic water processor made of NdFeB permanent magnets can be effectively used for magnetization of water. The magnetic water heater is usually made of a stainless steel casing with a set of NdFeB magnets with N poles and S poles opposite to generate a strong magnetic field. The length and angle of the water molecules are changed when the water is cut by the magnetic lines in the vertical direction through the intermediate channel. Subtle changes can occur, greatly increasing the activity of the water.

In daily life, we often see the scaling of water. This is due to the dissolution of calcium and magnesium bicarbonate in water. When heated, calcium and magnesium carbonate precipitates. The harder the water, the more scale. . Scale not only seriously affects heat transfer, reduces heat transfer efficiency of various heat exchangers, increases energy consumption, and causes blockage of pipes. To this end, many industrial and domestic water needs to be softened in advance. The commonly used methods are ion exchange and dosing chemical softening, which are time consuming and labor intensive. The use of NdFeB magnetic water processor can often replace the above-mentioned softening treatment method, and can also play the role of anti-scaling and descaling.

The water cooling system of the Institute of Electronics of the Chinese Academy of Sciences (Beijing) used to use the ion exchange method, which not only consumes materials, but also has special personnel to operate and manage. Later, it was changed to NdFeB magnetic water processor (manufactured by Beijing Sanhuan New Materials Co., Ltd.), which does not consume electricity or special personnel. It only needs to change the circulating water once a year. The system can be used for cooling equipment in the whole research institute. From 1991 to today, it has maintained good anti-scaling and anti-algae effects.

Many large buildings are now equipped with central air conditioners. Due to the high operating temperature of the compressors, it is necessary to quickly remove the heat with flowing cooling water. If tap water is used for cooling, scaling will occur, resulting in reduced heat exchange efficiency and reduced cooling capacity. The use of neodymium iron boron magnetic magnetic water heater also solves the scaling problem of water cooling system. The NdFeB magnetic magnetic water heater is also used in the heating water supply system of the central air conditioner, the cold storage water supply system, and the heat exchanger for domestic hot water.

Magnetized water can also prevent "scaling" in the human body, and often drink magnetized water, which has certain effects on preventing and treating stones in the urinary system and improving digestive function. Therefore, many mineral water pots and magnetic water cups also use NdFeB permanent magnets. The water is magnetized. Due to the high activity of magnetized water, good solubility and permeability, the use of rare earth permanent magnet magnetized water for agriculture, animal husbandry, forestry, and poultry and livestock breeding also has obvious effects of increasing production and income.

NdFeB permanent magnet magnetization technology is also used in the wine industry. Inner Mongolia Wulanhaote Brewery adopts magnetization treatment in brewing liquor, which plays the role of aging and ripening, which can shorten the aging time and improve the quality of liquor. The white wine produced by magnetization has a sweet and sweet taste. It has been tested by medical experts and moderately consumed. It also has the effects of lowering blood fat and blood sugar.

NdFeB permanent magnets are also used for magnetization of oil and gas fluids. In the oil exploitation, there is also "fouling" on the wall of the oil production pipe, that is, the phenomenon of wax formation occurs, which is easy to block the oil production pipe. After the installation of the NdFeB rare earth permanent magnet anti-wax device, the wax formation can be obviously reduced, the cleaning cycle is extended, and the heavy wax washing operation is reduced, thereby greatly improving the oil recovery efficiency.

NdFeB permanent magnet magnetization technology is also used for the magnetization of fuel gas. The car is equipped with a neodymium-iron-boron permanent magnet magnetized fuel-saving device. The magnetization pretreatment of the fuel can make the fuel burn more fully, and the average fuel economy of gasoline and diesel can reach 5%-8%, and the carbon monoxide in the exhaust gas can be reduced. The content of harmful gases such as hydrocarbons is both energy efficient and environmentally friendly. Based on the same principle, an energy-saving magnetizer for rare earth permanent magnet combustion has been developed, which is used for daily cooking and cooking, and has the dual effects of energy saving and environmental protection.

The emergence of "a generation of magnetic king" NdFeB rare earth permanent magnet materials has made a quantum leap in fluid magnetization technology. Hangzhou Vector Magnets Col, Ltd. is one of the major NdFeB permanent magnet materials manufacturers in China, and is able to provide patented NdFeB magnets various specifications according to different magnetization technologies. With the continuous development of industrial and agricultural production, rare earth permanent magnet NdFeB magnetization technology will be more and more widely used.
