Magnetic door curtain is a very common commodity door curtain in home textile products. It has a wide range of applications in supermarkets, banks, shopping malls and other occasions, and has good practicability.
I believe that when you go shopping in a bank or a large supermarket, you will encounter the magnetic suction door curtain at the door. After you push the door curtain and go in, the door curtain that is put down will be automatically magnetically attracted together to isolate the inside and outside.
The door curtains are automatically magnetically attracted together because the edges of the door curtains are wrapped with magnetic materials, which have a certain residual magnetism and a certain strength of the magnetic field. When the door curtain A is close to the door curtain B, the iron of the door curtain B will be magnetized, and the opposite polarity to the door curtain A will be induced, and the opposite sex will attract.
It is not difficult to see that magnetic materials exist in every corner of our lives. Magnetic materials belong to the new material industry and are an important branch of metal functional materials. This material has the characteristics of conversion, transfer, processing and storage, so it is an important basic functional material with a wide range of applications, which can be used in automobiles, Consumer electronics, automatic control, mineral processing and other fields. In recent years, with the country's promotion of energy conservation, environmental protection, and green development, it is being popularized and widely used in the fields of energy conservation and environmental protection, new energy, electric vehicles, smart cities, smart earth, robots, aerospace, and satellite remote sensing. The mass production of magnetic materials has maintained a growth rate of 8-10% every year. Among them, the application of NdFeB magnetic materials is the most prominent. NdFeB magnetic materials have many excellent properties and low prices, and are widely used in many fields. used and quickly realized industrial production. Most of the magnetic materials used to achieve the purpose of magnetic attraction of door curtains are NdFeB.
It can be seen that the self-absorption of the magnetic door curtain is actually the function of the magnetic material contained in the door curtain. The magnetic materials attract each other and can be summed up in one sentence: the same sex repels each other, and the opposite sex attracts each other. Another example: the process of attracting iron of a magnet is the process of magnetizing the iron block. The magnetized iron block and the magnet of different polarities have an attractive force, and the iron block is firmly "sticked" to the magnet.
