摘要
为了降低聚氨酯塑胶问题跑道对人体的损害,文章剖析了聚氨酯问题跑道产生的原因,并10所小学、中学、高校的塑胶跑道为研究样本对其中的有毒物质进行鉴定,结果表明,部分学校的甲苯和二甲苯总和、游离TDI的含量测定超标,大于国标GB/T14833-2011中规定的限值,针对这些问题提出了聚氨酯塑胶问题跑道的改进措施。
In order to reduce the damage of the polyurethane plastic track to the human body,this paper analyzes the causes of the polyurethane runway,and the plastic runways of 10 primary schools,middle schools and colleges are used to identify the toxic substances in the research samples.The results show that some schools the total content of toluene and xylene and the content of free TDI exceeded the standard,which was greater than the limit specified in GB/T14833-2011.The improvement measures for the polyurethane plastic problem track were proposed for these problems.
