NdFeB descaling anti-scaling work

- Nov 22, 2017 -

According to the characteristics of the magnet if the atomic current is explained by the magnetic field generated by the current magnetization of other objects, the magnetic field generated by the electric field, the interaction between the electric field force. Substance mostly composed of molecules, atoms are composed of atoms, atoms It is composed of nuclei and electrons. Inside the atom, the electron keeps spinning and rotates around the nucleus. Both types of movement of electrons produce magnetism. However, in most materials, the direction of electron movement is different and disorganized, and the magnetic effects cancel each other out. Therefore, most substances do not show magnetism under normal conditions.


Because magnetism is one of the basic properties of matter, all matter is a magnetic medium. Divided into three types:

1. Paramagnetic material, this material under the action of a magnetic field to produce the same with the external magnetic field, most of the material belong to this category,


2. Anti-magnetic material, this material in the magnetic field and the external magnetic field generated by the opposite magnetic field, such as copper and inert gases


3. Ferromagnetic material, this material under the action of a magnetic field to produce the same strong external magnetic field, such as iron cobalt cobalt.

Iron, cobalt, nickel or ferrite and other ferromagnetic substances are different, its internal electronic spin can spontaneously arranged within a small area to form a spontaneous magnetization zone, this spontaneous magnetization zone called magnetic domain. Ferromagnetic material after magnetization, the internal magnetic domain neat, aligned in the same direction, so that the magnetic reinforcement to form a magnet. Magnet iron absorption process is the magnetization process of iron, magnetized iron and magnet attraction between the different polarities, the iron firmly with the magnet "stick" together. We say the magnet is magnetic.


First, NdFeB descaling anti-scaling work

Water through the NdFeB high-strength magnetization, the water molecules at the same time the angle and length of the bond deformation, hydrogen bond angle decreased from 105 degrees to about 103 degrees, a series of changes in the physical and chemical properties of water, water activity and solubility greatly Improve the calcium carbonate in the water decomposition in the cooking process to generate lower soft calcium bicarbonate, easy to accumulate in the wall, easily removed by water. In addition the degree of polymerization of water increases, the dissolved solid matter becomes finer particles, the particle refinement, the distance between the two ions is small, not easy to condense on the wall, so as to achieve the effect of descaling.


Second, the history of magnetized water

Magnetism is one of the four basic forces in nature. One of the four great inventions in ancient China is an example of the clever application of magnetism. Ming Dynasty physician Li Shizhen as early as five hundred years ago has found that the magnetically treated water to physical fitness, treatment of various diseases. However, the ancients used the magnetic material is a naturally occurring natural magnet - magnetite, its magnetic properties and modern synthetic magnetic material is very low.


Third, high-strength magnetic king - NdFeB

In 1983, the third generation of neodymium iron boron come out, the magnetic field strength is ten times the ordinary magnet, the service life of up to ten years or so, is by far the highest in human society found the highest magnetic energy permanent magnet material, known as " Magnetic king. " Widely used in national defense, electronics, aerospace technology, microwave, communications, health care and other high-tech fields.


Fourth, NdFeB health cure principle

Due to the difference of the geographical environment and the different mineral content in the water, harmful substances in the water greatly affect our life and health. Calcium and magnesium salts in water have poor solubility and affect the absorption and photosynthesis of animals and plants. NdFeB high-intensity magnetization can change the physical properties such as surface tension, density and solubility of water and have a significant impact on the chemical properties of acids and bases Effect, magnetized water can increase the activity of enzymes in water and biofilm permeability, regular consumption can enhance health, conditioning the body's microcirculation system, digestive system, endocrine system and neural function, improve human immunity, prevention and treatment of a variety of disease. After high-strength magnetized water, water molecules are activated, high oxygen content. 1. Regular drinking can enhance physical fitness, improve human immunity, anti-aging, prevention and treatment of a variety of diseases, accelerate and promote the metabolism of the human epidermis, commonly used to make your skin becomes smooth and delicate, beauty photo; 2 often Drink can increase the permeability of biofilm, reduce blood viscosity, maintain blood vessel elasticity, prevent thrombosis, prevent and resolve stones.

    

At present, the global production of magnet magnetic materials is mainly concentrated in Asia and Japan with high-grade magnets as the mainstay. China takes low-middle-grade magnets as the main part and splits up some high-end product markets; other Southeast Asian countries split some middle and low-end product markets.


As China has a good machine configuration market and investment environment, accelerated the ferrite magnet manufacturing in Japan, Europe and the United States to China's transfer. It is estimated that the output of China's ferrite magnets will account for more than 60% of the global output by 2010, and NdFeB will occupy 80% of the world's total. China now has 1,096 magnetic material manufacturers, including 359 ferrite producers, 226 rare earth magnet and metal magnet manufacturers, and the rest are auxiliary equipment manufacturers and auxiliary raw material manufacturers. There are 197 permanent magnet ferrite producers with output of 410,000 tons (360,000 tons of sintered magnets and 50,000 tons of bonded magnets) and 162 soft ferrite producers with output of 300,000 tons (260,000 tons of manganese and zinc, Nickel-zinc and magnesium-zinc 40,000 tons), 40,000 tons of NdFeB magnets, and 0.35 tons of AlNiCo magnets.


China's ferrite industry basically maintained its growth rate of more than 20% with an average of doubling its output every five years. In recent years, China's ferrite magnet production quality and grade has greatly improved, basically able to produce various brands of Japanese TDK standard products. At present, permanent magnet ferrite products occupy 42% of high-tech applications, such as household appliances (microwave ovens, air conditioners, small appliances), office supplies (copiers and fax machines), automobiles, motorcycles, hi-fi and instrument sensors. 58% of the traditional application of low-end products, such as speakers, magnets, toys, motors, magnetic devices. Overall, the performance of ferrite magnets in China is still the majority of middle and low, although the output ranks first in the world, but the output value is not satisfactory. Now China's total output value of magnetic materials 26.5 billion yuan, output 6.2 billion permanent magnet ferrite, soft ferrite production 9.3 billion, the remaining samarium cobalt magnets, NdFeB magnetic and metal magnets account for 11 billion yuan market.


With the development of digital products and high-performance consumer products, magnetic materials products put forward higher requirements, such as high-definition color TV, digital, soft ferrite power loss, permeability, the use of frequency than the simulation requirements Machine high. Other digital camcorder, audio equipment, inverter air conditioner also put forward higher requirements for high-grade magnetic materials. In addition, the development of automobile, communication and computer industry has also led to the development of high-grade magnetic materials.
