Composite electromagnetic shielding materialIt is a new type of shielding material that refers to a multi-layer structure of shielding material formed by adding electromagnetic shielding components to the material. Composite electromagnetic shielding materials have multiple application values, including protecting equipment and personnel from electromagnetic interference, reducing the harm of electromagnetic radiation to the environment, and improving equipment reliability. The following will provide a comprehensive introduction to the structural composition, performance characteristics, and application examples of composite electromagnetic shielding materials.
1、 Structural composition of composite electromagnetic shielding materials
Composite electromagnetic shielding materials are usually composed of two or more layers of materials, including conductive composite materials and barrier composite materials. Among them, conductive composite materials refer to composite electromagnetic shielding materials with added conductive particles, which can play a role in conductivity and
Electromagnetic radiation shieldingThe role; Barrier composite materials refer to composite electromagnetic shielding materials with added barrier components, which can effectively block the propagation of electromagnetic radiation.
2、 Performance characteristics of composite electromagnetic shielding materials
Composite electromagnetic shielding materials have high electromagnetic shielding and low radiation properties, which can effectively protect equipment and personnel from electromagnetic interference and radiation effects. In addition, composite electromagnetic wave shielding materials also have good heat resistance, corrosion resistance, and wear resistance, and can be used normally in special environments such as high temperature, high pressure, and humidity.
3、 Application examples of composite electromagnetic shielding materials
Composite electromagnetic wave shielding materials are widely used in fields such as electronics, communication, radar, and radiation. For example, in electronic devices,
Composite electromagnetic wave shielding materialCan be used as a protective coating to reduce the resistance between electronic devices and the environment; In communication equipment, composite electromagnetic wave shielding materials can be used as shielding layers to isolate the interference of radio waves on communication signals; In radar equipment, composite electromagnetic wave shielding materials can be used as shielding layers to resist the influence of electromagnetic waves on radar received signals.
