With the rapid development of electronic technology, more and more electronic products and equipment are used in people’s production and life. Computers, radios and other transmitting equipment generate electromagnetic waves of different wavelengths and frequencies. Electromagnetic pollution is a new source of pollution after air pollution, water pollution and noise pollution. Therefore, more and more attention is paid to the electromagnetic shielding of related equipment.
Electromagnetic shielding is to use electromagnetic shielding materials such as metal to make a shielding body, to seal the area that needs to be protected, and isolate the electromagnetic pulse from the shielding body. Protect. When the pulse arrives, the electromagnetic energy of the shield will be reflected, absorbed or blocked. Even if electromagnetic waves can penetrate the shield, the electromagnetic energy and electromagnetic fields are attenuated to an acceptable level.
Electromagnetic shielding is one of the important measures to prevent electronic equipment and electronic systems from being subjected to electromagnetic interference. It can effectively reduce electromagnetic interference caused by space propagation. It can reduce the radiated EMI of electronic equipment and prevent the influence of external electromagnetic interference on electronic equipment.
As a special material, the conductor itself not only has electrical conductivity, but also can shield electromagnetic waves. However, in the daily use of such materials, the shielding effect of these materials will also be affected by some interference factors, such as environmental interference, frequency, intensity, etc., and the shielding effect of electromagnetic waves will also vary during use.

1. Principles
As for the material of conductive cloth, it is a relatively complete conductive material itself; therefore, this material can be bonded to any metal surface, so as to ensure that after bonding, the electrical sealing property of the electrical sealing gap can also be improved. To shield the role of electromagnetic signals.

2. Scope of application
The system has the characteristics of shielding electromagnetic signals and has a wide range of applications. It can be widely used in some strong radiation fields that need to shield electromagnetic signals, such as making professional shielding clothing, shielding room making shielding cloth, shielding gloves, radiation-proof curtains and other products.

3. Conductive foam
In addition to being suitable for some fields that need to shield electromagnetic signals, this system can also be used for EMI/EMC control of various electronic equipment. When preparing the material of foam cotton, it is only necessary to wrap it in the high elastic part of the foam, and cut it into different shapes and sizes according to different needs in the process of use, ensuring different use needs, and can make corresponding shape, the production process is very simple. Because the material can change its shape according to needs, it not only has a wide range of applications, but also has strong adaptability.
