The core part of an electromagnetic shielding window is an electromagnetic wave absorbing coating. This coating has high absorption capacity

Electromagnetic shielding windowAs the name suggests, it is a device used to shield external electromagnetic signals. In the industrial field, electromagnetic shielding windows have become an essential tool due to the need to isolate electric and magnetic fields. Below, the editor will briefly introduce the relevant content of electromagnetic shielding windows.

1、 The purpose of electromagnetic shielding windows

(1) Used for the production of electronic products, such as computer motherboards, televisions, etc.

(2) Used for connecting and conducting various electronic devices, such as telephone lines, network lines, etc.

(3) Used to prevent the generation of static electricity.

(4) Used to prevent external interference, such as inside a television receiver.

(5) Can be used for computer systems.

(6) Can be used in the military field.

2、 What is electromagnetic radiation

1. From an energy perspective, electromagnetic waves with frequencies higher than 3 × 108MHz (megahertz) in the electromagnetic spectrum have energy greater than the interaction between atomic nuclei and electrons in vacuum, and can penetrate objects, causing them to generate heat.
2. Electromagnetic waves with frequencies below 300mHz (megahertz) cannot pass through any object.

3. A frequency equal to 300mHz to 30GHz (kilohertz) is called microwave. 4. Infrared radiation with a wavelength less than 1mm can cause an increase in human body temperature.

5. A wavelength greater than 1mm is called visible light, which is an invisible radiation.

6. A wavelength shorter than 0.76mm is called ultraviolet.

7. The wavelength of approximately 0.76-1000 μ m is called X-rays or gamma rays, which can penetrate living organisms and pose a threat to human health.

8. The wavelength of about 1-100 μ s is called gamma rays, which are emitted by the nuclides that make up radioactive substances.

9. A wavelength shorter than 0.1nm is called cosmic ray, which is a high-energy photon from outer space.

10. A wavelength shorter than 0.001-100nm is called the ultra short band, which is commonly referred to as the microwave band, including the meter band, centimeter band, and decimeter band.

Electromagnetic shielding windowIt is an electromagnetic shielding device commonly used in electronic equipment, communication equipment, aviation equipment and other fields, which can shield electromagnetic radiation and protect the safety of equipment and personnel.
Firstly, the core part of the electromagnetic shielding window is the electromagnetic wave absorbing coating. This coating has high absorption capacity and can absorb electromagnetic waves before they enter the device, thereby achieving shielding effect. Electromagnetic wave absorbing coatings are generally made of materials such as metal fibers, glass, or polyimide.
Secondly, the material selection of electromagnetic shielding windows is also very important. Different materials have different absorption properties and need to be selected according to specific circumstances. For example, glass has good transparency and hardness, but is not scratch resistant, fragile, and not suitable as a material for electromagnetic wave shielding windows. Different devices and scenarios require electromagnetic shielding windows of different specifications, which need to be installed according to specific situations.
For example, in electronic devices, electromagnetic shielding windows need to be tightly connected to the device casing to prevent electromagnetic wave leakage. In communication equipment, electromagnetic shielding windows need to be tightly connected to signal lines and connectors to prevent signal leakage.
When selecting electromagnetic shielding windows, it is necessary to choose according to specific circumstances to ensure that the quality and performance of the product meet the requirements. At the same time, it is also necessary to understand relevant technology and market information in order to better choose suitable materials and products.
