摘要/Abstract

摘要： 分别对手机基站及电视发射塔等典型环境电磁辐射源附近的电磁辐射强度进行了测量。再以羰基镍粉和水性清漆为主要原料,制备出针对射频电磁辐射的复合涂料,对该涂料制备的屏蔽材料进行现场电磁辐射屏蔽效能测试。结果表明,典型电磁辐射源附近环境电磁辐射强度未超过国家控制限值,镍基复合涂料对环境中的射频电磁辐射具有较高的屏蔽性能。在本实验所采用配方及工艺条件下,当单位面积镍含量为0.015 g/cm²时,其屏蔽效能最高。

Abstract: The environmental electromagnetic radiation intensities near a TV transmitter tower and a mobile phone base station were measured. A composite coating for shielding radiofrequency electromagnetic radiation was prepared using nickel carbonyl powder and water-borne varnish as main raw materials. Experimental results show that the environmental electromagnetic radiation intensities near typical radiation sources do not exceed the national control limits. The nickel-based composite coating has high shielding performance for radio-frequency electromagnetic radiation in environment. Using the formula and technological conditions adopted in this experiment, the shielding effectiveness of the material is found to be optimal when the nickel content per unit area is 0.015 g/cm².

Key words: environmental electromagnetic radiation, nickel-base composite coating, shielding effectiveness
