摘要
随着现代信息技术的发展以及人为电磁能量逐年增长,有限空间内的电磁环境逐渐恶化,对人们日常的通讯、计算机、运输业和其他电子系统造成危害,研究电磁屏蔽与吸波砂浆非常有必要。采用石墨剂为主要吸收材料,电磁屏蔽效能达到了25 dB以上。用粉煤灰与膨胀珍珠岩进行对比试验,电磁波吸附效果相比石墨填料较差。
With the development of modern information technology and the increase of man-made electromagnetic energy year by year,the electromagnetic environment in the limited space is gradually deteriorating,causing harm to people's daily communication,computer,transportation and other electronic systems.The electromagnetic shielding and absorbing mortar studied in this paper is very necessary.When graphite agent is used as the main absorption material,the electromagnetic shielding efficiency reaches more than 25 dB.When using fly ash and expanded perlite,the electromagnetic wave adsorption effect is worse than that of graphite filler.
