【应用】中石科技可提供导电橡胶制品、FIP产品等屏蔽解决方案,附EMC基础知识详解
近年来,随着现代科学技术的发展,各种电子、电气设备不仅为社会生产提供了很高的效率,也为人们的生活提供了很大的便利。然而,随着日益复杂的电磁环境,高度集成的电子设备及系统产生的电磁辐射和干扰又会影响人们的生产和生活。电磁干扰则是指由电磁骚扰引起的设备或传输通道性能的下降,电磁干扰的三要素即:骚扰源、耦合途径、敏感源。目前,世界各国都加大了对电磁污染问题的研究,相继制定了相关的标准与法规以控制和净化电磁环境。
国家标准GB/T4365-1995《电磁兼容术语》对电磁兼容所下的定义为“设备或系统在其电磁环境中能正常工作且不对该环境中任何事物构成不能承受的电磁骚扰的能力。” 电磁兼容设计的目的主要有三方面:第一,设备内部的电路相互不产生干扰,达到预期的功能;第二,设备产生的电磁干扰强度低于特定的限值;第三,设备对外界的电磁干扰有一定的抵抗力。JONES(中石科技)拥有齐全的电磁兼容测试环境及设备,能够诊断和整改包括IEC61000系列的各类测试,比如静电测试、浪涌测试、EFT测试、传导测试、辐射测试、变频器加载功率电磁兼容测试等一系列的诊断和整改。

解决电磁干扰耦合问题的主要措施有屏蔽、滤波、接地、PCB设计。同时,系统级控制电磁辐射污染的最有效措施是电磁屏蔽,其主要目的是阻止射频电磁波,使其辐射强度抑制在安全范围之内。
屏蔽效能(Shielding Effectiveness,简称SE)的概念:为了定量描述屏蔽体的屏蔽效果,通常采用屏蔽效能表示屏蔽体对电磁骚扰的屏蔽效能和效果。屏蔽效能的定义为:
式中,E0和H0为入射到屏蔽体前的电场强度和磁场强度,E1和H1为穿过屏蔽体后的电场强度和磁场强度。
电磁屏蔽原理
目前,常用的计算均匀屏蔽材料屏蔽效能的方法是Schelkunoff公式,该公式利用了传输线模型,具体形式为:
SE=SEA+SER+SEM(dB)
式中:SEA为屏蔽材料的吸收损耗,dB;
SER为屏蔽体表面的单次反射损耗,dB;SEM为屏蔽体内部的多次反射损耗,dB。
根据电磁屏蔽吸收损耗公式,
吸收损耗与电导率和磁导率呈正相关。因此,高电导率、高磁导率材料的选择在电磁兼容解决方案中起着重要作用。
JONES可提供的屏蔽产品主要有各类导电橡胶制品、FIP产品、吸波橡胶、导电泡棉、导电布衬垫等。根据客户的具体应用场景,JONES工程师可通过评估屏蔽性能要求、环境密封要求、安装结构要求、成本要求,制定出相应的解决方案。
1、导电橡胶
JONES导电橡胶是自主研发,通过在硅橡胶中添加导电微粒制成的一种高分子材料,具有良好的电磁屏蔽效果,同时具备优异的水汽密封性、抗腐蚀性。独立开发的配方,使JONES的导电橡胶产品具有更宽的工作温度范围和更长的使用寿命。JONES导电橡胶产品系列可以提供:模压衬垫、共模压衬垫、挤出橡胶条、共挤导电橡胶条、涂覆导电橡胶条等。

你知道常见的电磁屏蔽材料有哪些吗?
电磁屏蔽的作用原理是利用屏蔽体对电磁能流的反射、吸收和引导作用,其与屏蔽结构表面和屏蔽体内部感生的电荷、电流与极化现象密切相关。电磁屏蔽指的是对电场(E场)的屏蔽,它通常可选用的屏蔽材料种类比较多。
