What are the surface treatment methods for bonding neodymium iron boron magnets?

The surface treatment of bonded neodymium iron boron magnet products mainly adopts epoxy resin [electrophoresis] method. In addition, coating and surface treatment processes such as acrylic resin electrophoresis, epoxy resin spraying, Teflon spraying, Perrin deposition, vacuum impregnation can also be carried out to meet the requirements of corrosion resistance, solvent resistance, and friction resistance for daily and long-term use in different environments. The specific coating requirements can be selected and stacked according to the environmental requirements of use.Bonded neodymium iron boron is commonly used in stepper motors, spindle motors, and various types of motors and sensors, such as stepper motors used in optical disc machines, photocopiers, and fax machines, instrument panels used in the automotive industry, electric seat adjustment motors, and airbag sensors.

What are the applications and impacts of neodymium iron boron magnets in industry?

Neodymium iron boron magnets are becoming an important factor affecting the development of manufacturing industries in various countries, and neodymium iron boron is one of the main raw materials for manufacturing environmentally friendly and energy-saving products.The application of neodymium iron boron in fields such as automobiles, compressors, and wind turbines is precisely based on environmental protection and energy conservation considerations. As an environmentally friendly and energy-saving functional material, neodymium iron boron will be more widely used by magnet manufacturers. In an era of increasing energy scarcity, the conversion of wind energy into electricity will undoubtedly be supported by government policies. Wind power generation has been implemented on a large scale in Europe. Previously, 1 megawatt units used approximately 1 ton of neodymium iron boron. Thanks to the rapid growth of the wind power industry, the use of neodymium iron boron in wind turbines will als

Basic properties of magnets

1. Properties of magnets: Magnets have magnetism and can attract iron objects.2. Magnets have magnetic poles, and every magnet manufacturer produces magnets with two types of magnetic poles: N-pole and S-pole, which exist in pairs.3. Temporary magnet and permanent magnet: When ferromagnetic materials are magnetized and easily lose their magnetic properties, they are called temporary magnets (such as iron); When ferromagnetic materials are magnetized and do not easily lose their magnetic properties, they are called permanent magnets (such as steel).4. The magnet manufacturer believes that when two magnets are close to each other, the same magnetic poles will repel each other and push apart, while different magnetic poles will attract and stick to each other. So it is said that the same poles repel each other, and the opposite poles attract each other.

Introduction to permanent magnet suction cups

In China's mechanical processing, mold manufacturing, metallurgy and other industries, some heavy steel or iron plates, precision or surface roughness requirements of steel processing products or semi-finished products, etc. were previously mostly lifted using steel wire rope bundling, or using electromagnets for lifting. However, electromagnets have a large volume, high cost, multiple faults, and maintenance difficulties. In addition, electromagnets consume a large amount of electrical energy during operation, and once power outage occurs, Accidents are prone to occur. With the emergence of high-performance neodymium iron boron rare earth materials, the development of magnetic tools using neodymium iron boron permanent magnetic materials has become a trend, and permanent magnetic suction cups have emerged.Permanent magnet suction cups, also known as magnetic suction cups or permanent magnet hoists, are essential tools for handling steel materials in machinery factories, mold facto

Magnet manufacturers introduce the composition and properties of magnets to you

Firstly, as a magnet manufacturer, we will inform you that the composition of the magnet is formed by the arrangement of atoms such as iron, cobalt, and nickel through a special internal structure. The original magnet itself has magnetic moments. In general, the arrangement of these mineral molecules is relatively chaotic. And their magnetic regions interact with each other and do not show magnetism, but under the guidance of external forces (such as magnetic fields), the arrangement direction of their molecules will tend to be consistent with the magnet, and their magnetism will show a significant difference. Magnets are divided into permanent magnets and soft magnets. Permanent magnets add a strong magnet, which causes the spin of the magnetic material and the angular momentum of the electrons to be arranged in a fixed direction. Soft magnets add current (also a method of adding magnetic force), and removing the soft iron will gradually lose its magnetism. The earliest person who dis

Common chemical reactions

At high temperatures, it easily oxidizes into iron oxide. 4Fe3O4+O2=high temperature=6Fe2O3It can react with reducing agents such as CO, Al, and C at high temperatures. 3Fe3O4+8Al=High temperature=4Al2O3+9FeFe3O4+4CO=high temperature=3Fe+4CO2Under heating conditions, it can react with reducing agent hydrogen gas. Fe3O4+4H2=△=3Fe+4H2OThe reaction between nitrogen dioxide and hot iron powder generates ferric oxide and nitrogen 3Fe+2NO2=high temperature=Fe3O4+N2Iron burns in oxygen to form ferric oxide 3Fe+2O2=ignited=Fe3O4The reaction between hot iron and water vapor generates ferric oxide, 3Fe+4H2O (g)=high temperature=Fe3O4+4H2React with acid Fe3O4+8HCl=FeCl2+2FeCl3+4H2O
