The working principle of descaling and anti-scaling of neodymium disc magnets
After the water passes through the neodymium disc magnets high-strength magnetization treatment, the water molecular bond deforms both in angle and length. The hydrogen bond angle is reduced from 105 degrees to about 103 degrees, which causes a series of changes in the physical and chemical properties of water
After the water passes through the neodymium disc magnets high-strength magnetization treatment, the water molecular bond deforms both in angle and length. The hydrogen bond angle is reduced from 105 degrees to about 103 degrees, which causes a series of changes in the physical and chemical properties of water, and the activity of neodymium disc magnets. And the solubility is greatly improved, the calcium carbonate in the water is decomposed during the cooking process to produce lower soft calcium bicarbonate, the neodymium iron boron magnet is not easy to accumulate on the wall, and it is easy to be taken away by the water. In addition, the degree of polymerization of water increases, and the dissolved solid matter becomes finer particles. After the particles are refined, the distance between the two ions is small, and it is not easy to condense on the wall, thereby achieving the effect of descaling.
1. According to the company's requirements for manufacturing high-end or mid-range or low-end sintered neodymium disc magnets, the raw materials are selected according to the raw material composition specified by the national standard.
2. Whether the production process is advanced or not directly determines the performance and quality of the magnet. The current advanced technologies are scale ingot (SC) technology, hydrogen crushing (HD) technology and jet mill (JM) technology. Small-capacity vacuum induction smelting furnaces (10kg, 25kg, 50kg) have been replaced by large-capacity (100kg, 200kg, 600kg, 800kg) vacuum induction furnaces. SC (StripCasting) rapid-setting cast sheet technology has gradually replaced large ingots (ingots with a thickness greater than 20-40mm in the cooling direction), and hydrogen crushing (HD) technology and jet mill (JM) have replaced jaw crushers and disc mills. The machine and ball mill (wet milling) ensure the uniformity of the powder and are beneficial to liquid phase sintering and grain refinement.
3. In terms of magnetic field orientation, my country is a country that adopts two-step compression molding. It uses small pressure vertical compression molding during orientation, and then adopts quasi-isostatic compression molding. This is one of the characteristics of my country's neodymium disc magnets industry.
