How to apply low permeability absorbing materials to electromagnetic pollution prevention to improve environmental quality?

With the rapid development of modern technology, the application of electromagnetic devices in our daily lives is becoming increasingly widespread. However, the accompanying electromagnetic pollution problem is becoming increasingly serious, posing a potential threat to human health and the living environment.Low permeability absorbing materialAs a special electromagnetic functional material, it has significant electromagnetic wave absorption ability, which can effectively reduce electromagnetic interference and leakage, thus playing an important role in electromagnetic pollution prevention. This article will explore how to apply low permeability absorbing materials in electromagnetic pollution prevention to improve environmental quality.

Characteristics of low permeability absorbing materials

Low permeability absorbing materials have lower magnetic permeability and significant electromagnetic wave absorption ability. These materials convert electromagnetic wave energy into other forms of energy (such as thermal energy) through specific mechanisms (such as resistive loss, dielectric loss, and magnetic loss), thereby achieving absorption of electromagnetic waves. Its main characteristics include:

1. Broadband absorption: exhibiting good absorption characteristics over a wide frequency range, suitable for electromagnetic wave interference at various frequencies.
2. Lightweight and Durable: Lightweight, easy to carry and install, and resistant to temperature, moisture, and corrosion, maintaining stable performance in harsh environmental conditions.
3. Low magnetic permeability: The degree of magnetization under the action of a magnetic field is relatively low, making it difficult to magnetize and possessing specific electromagnetic properties.

   • In electronic devices such as laptops, mobile phones, and communication cabinets, low magnetic permeability absorbing materials can be used to reduce electromagnetic interference and improve the stability and reliability of the equipment. By coating or pasting absorbing materials on key parts inside or outside the device, the interference of electromagnetic waves on the internal circuit of the device can be effectively reduced.

2. Military and Defense

   • Coating on weapons and equipment such as airplanes, missiles, tanks, etcLow permeability absorbing materialIt can absorb reconnaissance radio waves, attenuate reflected signals, and achieve stealth effect. This stealth technology has extremely important strategic significance in the military field, as it can reduce the risk of equipment being detected by the enemy and improve combat effectiveness.

3. Communication equipment

   • Low permeability absorbing materials can be used to reduce electromagnetic radiation interference and improve antenna efficiency. In radar systems, it can be used to reduce the interference of sidelobes on the main lobe, increase the range of the transmitting antenna, and improve the sensitivity of the receiving antenna. In satellite communication systems, it helps to avoid interference between communication lines and improve communication quality.

4. Electromagnetic protection

   • Using low magnetic permeability absorbing materials near high-power radar, communication equipment, microwave heating and other devices can prevent electromagnetic radiation or leakage, and protect the health of operators. At the same time, they can also be used to conceal military facilities, such as airport navigation equipment, ship masts, etc.

Practical operation and case analysis

Taking a certain communication base station as an example, there is a serious electromagnetic radiation pollution problem around the base station. To solve this problem, engineers installed shielding devices made of low magnetic permeability absorbing materials around the base station. After a period of use, the electromagnetic radiation level around the base station has significantly decreased, effectively protecting the health of surrounding residents.
