Shielding material: a protective scheme that isolates interference outside of enclosed spaces

Introduction: With the continuous advancement of technology and the popularization of electronic devices, electromagnetic radiation poses a certain threat to people's lives and health. (取决于上下文，如"but"Shielding materialThe application becomes the key to solving this problem. This article will introduce the application and selection guide of shielding materials, providing readers with a better understanding and basis for selecting shielding materials.

1. Hazards and Requirements of Electromagnetic Radiation

Electromagnetic radiation refers to the energy generated by the propagation of electromagnetic waves through air, solids, or liquids. During the use of electronic devices, the propagation of electromagnetic waves cannot be avoided, and prolonged exposure to electromagnetic radiation can have certain effects on human health, such as muscle fatigue, difficulty falling asleep, and weakened immunity. Therefore, protecting oneself from electromagnetic radiation has become an important requirement.

2. Definition and classification of shielding materials

Shielding material is a special material that can effectively absorb, reflect, or scatter electromagnetic radiation and block it outside of enclosed spaces. According to their ability to absorb and reflect electromagnetic radiation, shielding materials can be divided into absorption type and reflection type. Among them, absorbing materials can convert electromagnetic wave energy into micro thermal energy and release it into the air; Reflective materials achieve the purpose of blocking by reflecting electromagnetic waves.

3. Application areas of shielding materials

Shielding materials have a wide range of applications, such as telecommunications, medical equipment, aerospace, etc. In the field of telecommunications,Shielding materialMainly used in the casing, display screen, power module, etc. of electronic products to prevent the generation and propagation of interference signals. In medical equipment, shielding materials are used to isolate electromagnetic radiation between different devices, ensuring the stable operation of medical equipment. In the aerospace field, shielding materials can reduce electromagnetic interference between internal equipment of aircraft and improve flight safety.

4. Selection guide for shielding materials

(1) Material properties: When selecting, the absorption and reflection capabilities of the shielding material should be considered. Materials with good absorption ability can convert electromagnetic waves into micro thermal energy, while materials with good reflection ability can reflect electromagnetic waves back in their original direction.

(2) Transparency: Transparency refers to the ability of shielding materials to penetrate visible light. In certain application scenarios, shielding materials are required to prevent electromagnetic radiation without affecting the normal observation or operation of the equipment.

(3) High temperature resistance: Equipment in certain industries can generate high temperatures, so shielding materials with good high temperature resistance are chosen to ensure their stable and effective shielding of electromagnetic radiation.

(4) Cost and flexibility: Choose shielding materials with high cost-effectiveness based on actual needs and budget. In addition, plasticity is also one of the factors to consider, as certain scenarios have special requirements for the shape, size, and adaptability of shielding materials.

(5) Compliant with environmental standards: Shielding materials should comply with relevant environmental standards to ensure that they do not pose potential threats and risks to the environment and human health during use.

Conclusion:Shielding materialThe application and selection guidelines are becoming increasingly important in today's technological environment. By understanding the hazards and requirements of electromagnetic radiation and selecting suitable shielding materials, it is possible to effectively protect people's health and ensure the stable operation of equipment. Practical selection of shielding materials, so that electromagnetic radiation no longer troubles our lives and work.
