What shielding materials are available for electromagnetic shielding rooms?

Author:admin   AddTime:2021-05-04

There are many kinds of shielding materials used in electromagnetic shielding rooms, which provides more shielding material choices for the construction of electromagnetic shielding rooms. How much do you know about various shielding materials? Let us introduce the various shielding materials for electromagnetic shielding rooms.

1. Polymer shielding material: It is a new type of polymer material, and it must have the characteristics of light weight, easy forming, and adjustable resistivity with metals.

2. Thin metal film shielding material: usually use metal spraying, plastic electroplating, vacuum evaporation, rolling metal foil and other means to cover the surface of the material with a conductive layer. The advantage is that the shielding efficiency is better, but the processing cost is high, the construction is difficult, and the equipment requirements are high.

3. Metal plate shielding material: used in shielding room, the advantage is high and stable shielding performance, but the construction is troublesome and the comfort is poor.

4. Shielding cloth and fiber felt. It is made of metal fiber mixed with fabric, and the shielding index is low, usually below 20dB. It is mainly used for shielding clothing. Electroless metal plating mainly includes silver plating, copper plating, and nickel plating.

5. Breathable shielding materials: there are metal mesh, cut-off waveguide windows, foam metal, etc., which are mainly ventilated and breathable, but have poor shielding effectiveness against high-frequency electromagnetic waves.



6. Light-transmitting shielding material: mainly shielding glass, which is made by coating or wire clamping. The electromagnetic wave shielding index is good, but the antimagnetic performance is poor.

7. Shielding concrete or shielding mortar material: It is made of composite materials mixed with conductive fiber, metal powder, graphite and other materials.

8. Pad shielding material: mainly used for seam shielding.

9. Wave-absorbing shielding materials: non-metallic wedge, ferrite bricks, etc., mainly used for shielding darkrooms.

From the numerous shielding materials above, it can be seen that there are still many shielding materials to choose from for our electromagnetic shielding room. Here I will tell you about each different shielding material. You can choose the shielding material for the electromagnetic shielding room according to the advantages and disadvantages .
