Materials for shielding electromagnetic radiation - conductive cloth

There are many materials for shielding electromagnetic radiation, but if it is thin enough and soft enough, then conductive cloth is your best choice! Conductive cloths made of such materials are currently mainly used for shielding electromagnetic signals. Many people don't know how these materials shield electromagnetic signals. So, how exactly does this material shield from electromagnetic signals?

1. Factors and processes that affect the effect of the screen

In the process of shielding electromagnetic signals, the quality of the shielding effect mainly depends on whether the surface of the shield can continue to conduct electricity, and also depends on whether the surface of the conductor can directly penetrate the shield. In the production process of conductive cloth, it is mainly produced by vacuum galvanizing, electroplating and other processes.

2. Principle of electromagnetic signal shielding

In objects shielding electromagnetic signals, there are often many discontinuous conductive points. Therefore, to shield electromagnetic signals, these non-conductive points must be removed. Since these gaps are like fluids, in the process of eliminating these conductive discontinuities, electromagnetic signals will leak due to gaps, so for shielding, conductive elastic materials must be used to prevent the leakage of electromagnetic signals that may occur in these gaps. gaps are repaired. In the production process, the conductive cloth mainly uses a special chemical deposition method or a physical conversion method to convert metallic nickel into polyester; 5 layers of nickel are repeatedly plated, and a layer of copper with high conductivity can be used to fill these gap; so that the conductive cloth material has very good conductivity and electromagnetic shielding.

3. Functions and main application scenarios

This kind of material itself has good electromagnetic shielding properties; at the same time, it also has good metal film bonding force and curing; it is also very strong and durable, so it is often used in some places with high-intensity electromagnetic radiation.

For example, such materials can be seen on ordinary electromagnetic shielding work clothes, electromagnetic shielding work gloves, foot covers and other shielding special equipment; at the same time, this material is also widely used in some electronic products.
