Abstract

This research work determined the emission characteristics and elemental composition of selected PVC ceiling materials common in Nigerian markets especially during service. This research work determined the emission characteristics and elemental composition of selected PVC ceiling materials common in Nigerian markets. The emission data and elemental structure gave insight to appraise their suitability as ceiling materials. Three PVC ceiling materials were used for this analysis: Nigerian made PVC, layered Composite PVC and white PVC. Rutherford Backscattering Spectrometry (RBS) was performed to obtain the elemental structure of the ceiling materials using Ion Beam Analysis facility. 0.05 kg of the samples were combusted in a controlled fire chamber and the gasses emitted; CO, SO2, NO, and volatile organic compounds (VOC) were identified using four gas analyzers. Elements were detected in total and data collected from the experiment were analyzed. Results showed that Nigerian made PVC has the highest total noxious gas among the three samples with value of 3732.5 ppm while layered composite PVC has the lowest among the PVCs with the value of 1477.5 ppm. The elemental make-ups of the samples influence their emission characteristics. The study established that PVC samples were noxious in terms of their emission characteristics due to the effects of their elemental basis.

辐射特性对选定PVC天花板材料元素组成的影响

这项研究工作确定了尼日利亚市场上常见的PVC天花板材料的排放特性和元素组成，特别是在使用期间。这项研究工作确定了尼日利亚市场上常见的PVC天花板材料的排放特性和元素组成。排放数据和元素结构为评估其作为天花板材料的适用性提供了见解。该分析使用了三种PVC天花板材料:尼日利亚制造的PVC，分层复合PVC和白色PVC。利用离子束分析设备进行卢瑟福后向散射光谱(RBS)分析，获得天花板材料的元素结构。0.05 kg的样品在受控的火室中燃烧并释放出气体;CO, SO2, NO和挥发性有机化合物(VOC)使用四个气体分析仪进行鉴定。对实验中收集到的数据进行了分析。结果表明，尼日利亚产PVC的总有害气体含量最高，为3732.5 ppm;层状复合PVC的总有害气体含量最低，为1477.5 ppm。样品的元素组成影响其发射特性。该研究确定PVC样品由于其元素基的影响，在其排放特性方面是有害的。
