水泥基电磁生态环境材料的工程应用

Research on Application of Electro-Magnetic Ecotypic Environmental Cementitious Material

通过对水泥电磁生态环境材料应用的分析,选择具有较好电损耗和磁损耗性能的多晶系纳米掺杂铁氧体为吸波剂,按一定掺量配制建筑吸波砂浆,进行现场工程应用试验.结果表明,建筑吸波砂浆施工性能良好,可有效吸收、衰减由配电设备工作时产生的几十兆赫的电磁辐射,改善周边的电磁环境.

By analyzing application of electro-magnetic ecotypic environmental material, multicrystalloid ferrite powder were chosen as electro-magnetic wave absorber, which possesses good properties of electro-magnetic loss. A site experiment has been carried out in a power switch room by plastering the wave absorbing mortar in one residential project. The wave absorbing mortar has a good workability with satisfied finish, and has an notable attenuation of electromagnetic energy within the testing space at the range of 1-50 MHz.
