【产品】派克固美丽为现代军事应用提供全面的电磁屏蔽材料和产品
军工技术,一直是先进技术和高标准应用的代名词,现代军用电子技术更是如此。各种军用电子设备,在海陆空三军应用中的配置数量不断增加,同时其功能和复杂程度也在不断增加。在军用设备的设计过程中,EMI电磁屏蔽是必须要考虑的一个重点,因为无论是来自敌方的无线电干扰信号或是己方设备间的互相干扰,这在战场上都会造成严重后果,带来血的教训。美国PARKER CHOMERICS(派克固美丽)公司作为屏蔽行业的领先者,为各种军用设备和军事应用提供了多种多样的屏蔽材料和产品,本文对各种可用的产品类型做一下简单介绍。
图1 军事航空应用中适用的EMI屏蔽产品
首先说一下军事航空应用,在现代军用飞机的应用中,为了确保飞行员的人身安全,以及确保军事任务的完成,配置了大量先进的空中电子辅助系统和设备。同时这种多系统多设备的密集集成应用,也带来了复杂的EMI屏蔽需求和散热需求,如果不能得到妥善解决,极有可能造成设备故障或者性能下降,严重的会危及飞行安全和飞行员的生命。派克固美丽为此推荐了一些适合航空应用的屏蔽产品,包括POLA® SOLID系列导电橡胶,可制成屏蔽垫圈,具有优秀的电磁屏蔽和水汽密封效果,性能和结构稳定性都特别好;POLA® SPONGE系列导电泡棉,可以制成各种平面垫片,压缩应力小且具有天气密封效果,可以防风雨;STREAMSHIELD™系列屏蔽通风面板,屏蔽效能高、空气流量大,散热和屏蔽效果都不错;WIN-SHIELD™系列屏蔽保护窗,屏蔽和透光效果好,耐冲击、耐刮擦、耐腐蚀;CHO-SHIELD®系列导电涂料,用于机身和各种结构法兰,能够提供额外的EMI屏蔽和导电接地性能,等等。
图2 军用单兵设备中适用的EMI屏蔽产品
现代军用单兵设备的电子化程度也是越来越高,士兵随身配置的电子设备可能有通信系统、GPS、侦察设备、视觉系统和控制面板,等等。在单兵设备的应用中,除了性能保障以外,最重要的要求就是小型化便携式,以及适合人体应用。派克固美丽为此也推荐了大量适用产品,除了通用的垫圈、垫片之外,重点介绍几个特别的产品类型。PREMIERTM系列导电塑料,可用于制作各种电子设备的屏蔽外壳,替代传统金属铸件方案,优点是性能好、重量轻、材料强度高,符合轻型化、便携式的要求,目前该种塑料已经作为军用无线电设备的屏蔽外壳正在使用中。CHOFORM®系列原位成型导电垫圈,优点是结构设计简单,能够轻松实现整体垫圈的解决方案,而不占用太多的法兰空间,正是小型化设备需要的产品特点。WIN-SHIELD™系列屏蔽保护窗,可用作各种设备显示器的屏蔽应用,同时起到一定的保护作用,而且可以提供防反光、防眩光、防窥屏等多种特殊特性,符合人体应用的特点。
图3 武器系统中适用的EMI屏蔽产品
武器系统是战场上能够直接决定生死的关键部分,因此各种武器导航系统和导弹弹头部分的EMI屏蔽应用,是十分重要的。目前派克固美丽的各种屏蔽垫圈产品,已经在大量的武器系统中投入使用,例如车载导航系统,能够帮助系统安全精确的引导导弹轨迹。可用的垫圈类型包括导电橡胶垫圈(CHO-SEAL®)、金属指形簧片(SPRING-LINE®)、原位成型垫圈(CHOFORM®)、金属化塑料垫片(Metalastic™)、定向金属丝垫圈(POLA®)、压缩金属网垫圈(SHIELDMESH™)和导电泡棉垫圈(SOFT-SHIELD®),等。另外,CHO-SHIELD®系列导电涂料也用在各种导弹弹头外壳和车辆壳体上,起到额外增强电磁屏蔽效果和导电接地性能。

【选型】适用于EMP防护应用的屏蔽材料类型:金属指形簧片、金属编织网、金属箔胶带、导电塑料
本文谈到的是以防EMP破坏应用为重点的产品,先简单讲一下什么是EMP,以及防EMP产品的特点。从EMP的特性出发,显然需要的就是能够在短时间内快速导出大量电磁能量的产品,并且屏蔽效能要足够高,能够衰减绝大部分的电磁能量。因此,这种EMP应用通常选择的是金属材料制品,同时保证大载流量、高屏蔽效能和高导电性能。笔者从派克固美丽产品库中,筛选了几个适用于EMP防护应用的产品类型。
