Problems solved by technology

[0002] With the substantial increase of electronic and electrical products, while bringing convenience to people, it also brings electromagnetic pollution to people, causing great harm to people's health, and also causes interference and signal to electronic equipment and instruments. Distortion, mistakes, and even major accidents, how to protect the human body from electromagnetic radiation, and electronics, instruments and equipment from interference, has become a hot research topic in the scientific and technological circles and business circles of all countries in the world. The existing shielding materials, Such as steel plate, copper mesh (braided copper wire), and electroless nickel-plated mesh can solve the shielding technical problems of general electronic equipment and shielding rooms, but they have high cost and are not easy to install, so they are not suitable for shielding parts of electronic and precision instruments.
For example, the shielding conductive mesh used in mobile phones, plasma TVs, and precision instruments is still monopolized by Japan in the domestic market. The traditional chemical plating process is not only costly, but also causes serious pollution.
The single vacuum plating not only has the technical problem of easy oxidation of the surface, but also has poor shielding performance. The surface resistance can only reach 5Ω / cm, while the conductive mesh fabric made in Japan used in mobile phones and plasma TVs has a surface resistance of about 0.014Ω / cm. In short, the traditional technology cannot meet the requirements of the rapid development of electronic instruments
