After the high-magnetization treatment of water by NdFeB, the water molecules are simultaneously deformed by angle and length, and the hydrogen bond angle is reduced from 105 degrees to 103 degrees, so that the nature of the water in physical and chemistry is changed , the water activity and solubility are greatly improved, the calcium carbonate in the water decomposes during the cooking process to form a lower soft calcium bicarbonate, which is not easy to accumulate on the wall and is easily taken away by the water. In addition, the degree of polymerizat.ion of water is increased, and the dissolved solid matter becomes finer particles. After the particles are refined, the distance between the two ions is small, and it is difficult to condense on the wall, thereby achieving the effect of descaling. Pine cleaner is a kind of application for the application of neodymium magnet. Others, such as Permanent magnet magnetization anti-scaler.
