合成材料跑道面层在典型亚热带环境下有害挥发物质的方法研究

Study on Hazardous Substances of Synthetic Material Runway Surface Layer in Typical Subtropical Environment

随着橡胶跑道的逐渐普及,其危害性一致成为热点话题。本文通过模拟亚热带气候环境条件对跑道面层材料进行有害物质释放量的测试,研究表明有害物质主要集中在甲醛、乙醛、丙酮三类;温度越高醛类的释放量越大;苯系物的含量都是基本符合要求。

With gradual popularization of rubber track,its harmfulness has become a hot topic.The release of harmful substances from runway surface materials is tested by simulating in subtropical climate and environment conditions in this paper.The results showed that harmful substances mainly concentrated in formaldehyde,acetaldehyde and acetone,the higher the temperature is,the more aldehydes releases.The content of benzene homologues are basically in line with requirements.
