Electromagnetic shielding conductive clothIt is a material used to protect electronic devices from electromagnetic interference, usually made of conductive fibers (such as silver paste, copper paste, etc.) and fibrous conductive materials (such as polyaniline, polythiophene, etc.). Electromagnetic shielding conductive cloth has good conductivity and thermal conductivity, which can effectively reflect and absorb electromagnetic interference, thereby reducing the impact of electromagnetic radiation on equipment and personnel.
The performance characteristics of electromagnetic shielding conductive cloth mainly include the following aspects:
Electromagnetic shielding conductive cloth has high shielding effectiveness, which can effectively interfere with the propagation of target electromagnetic waves and reduce their impact on equipment and personnel.
Electromagnetic shielding conductive cloth has good conductivity and thermal conductivity, and can maintain its performance stability over a wide temperature range.
Electromagnetic shielding conductive cloth has good anti-interference properties and can maintain its stable performance in various environments. For example, it can maintain stable performance even in harsh environments such as high temperature, high humidity, and high frequency.
Electromagnetic shielding conductive cloth is suitable for various electronic devices, including televisions, computers, mobile phones, etc. During use, it is important to avoid mixing electromagnetic shielding conductive cloth with other materials to avoid affecting its performance.
Solution polymerization is the process of connecting conductive fibers (such as silver paste, copper paste, etc.) to monomers through chemical bonds, and then adding solvents or other additives to form a solution. The conductive fiber materials prepared by this method have high conductivity and thermal conductivity.
Polymer filling is the process of filling conductive polymer materials (such as polyaniline, polythiophene, etc.) into polymer materials to form composite materials. The conductive fiber material prepared by this method has good mechanical properties and electromagnetic interference resistance.
The selection of electromagnetic shielding conductive cloth needs to consider multiple factors, and the following are some possible selection considerations:
1
Electromagnetic shielding conductive clothThe shielding effectiveness is usually an important indicator for measuring its protective effect. When choosing electromagnetic shielding conductive cloth, it is necessary to consider its shielding effectiveness, including factors such as the thickness, area, and material of the shielding layer.
2. The conductivity of electromagnetic shielding conductive cloth is also a consideration factor in the selection. Some electromagnetic shielding conductive fabrics may require the use of special catalysts and other materials, which may affect their conductivity. Therefore, when choosing electromagnetic shielding conductive cloth, it is necessary to consider whether its conductivity meets the requirements.
3. The anti electromagnetic interference performance of electromagnetic shielding conductive cloth: Electromagnetic interference usually comes from external or internal electromagnetic interference, such as mobile communication, broadcasting, radar, etc. These interferences may have an impact on electronic devices, thereby affecting their shielding effectiveness. Some electronic devices require a large amount of electromagnetic shielding conductive cloth, and the high price may cause unnecessary waste.
4. Protective occasions and usage requirements: The requirements for electromagnetic wave protection vary depending on the purpose and usage environment. Some electromagnetic waves may have an impact on electronic devices, while others may have negative effects on human health. Therefore, when selecting electromagnetic emission protection materials, it is necessary to consider whether their protection scenarios and usage requirements meet the requirements.
In addition, the electromagnetic shielding conductive cloth also has some special properties, such as good heat resistance, acid and alkali resistance, moisture resistance, and strong aging resistance, which can adapt to different environmental conditions.
