摘要:
为探究胶粉改性沥青烟气释放的影响因素及影响机制,在制备不同胶粉改性沥青的基础上,利用自制烟气发生与检测装置,结合重量法、便携式气体检测仪和气相色谱质谱联用仪( GC-MS) 3 种检测手段测定沥青烟气及有害成分含量,并采用灰色关联法分析影响因素与烟气质量浓度的关联度;此外,通过四组分分析、红外光谱分析和荧光显微镜探究不同因素对烟气释放的影响机制。 结果表明:基质沥青标号和添加剂类型是影响沥青烟气释放的主要因素;四组分测试表明,胶粉改性沥青的烟气主要来自轻质组分的挥发;红外光谱测试显示,芳烃与烷烃含量是影响烟气及 VOCs 体积分数的主要因素,而沥青中的总硫含量则是控制 H2S 释放量的关键因素;荧光显微试验进一步证实,稳定的内部结构能在一定程度上抑制胶粉改性沥青的烟气释放。
Abstract:
To investigate the influencing factors and mechanisms of fume release from crumb rubber modified as-phalt,based on the preparation of different crumb rubber modified asphalts, a self-developed fume generation and detection device was utilized, combined with three detection methods including gravimetric method, portable gas detector, and gas chromatography-mass spectrometry(GC-MS) to determine the concentrations of asphalt fumes and harmful components. The grey relational analysis was performed to evaluate the relationship between various factors and fume concentrations. Further characterization using four-component analysis, infrared spectroscopy, and fluo-rescencemicroscopy was conducted to explore how different factors affect the underlying mechanisms of fume re-lease.The results showed that the base asphalt grade and additive type were the main factors affecting asphalt fume release. The four-component test showed that fumes from crumb rubber modified asphalt mainly came from the vol-atilizationof light components. The infrared spectroscopy test indicated that the contents of aromatic hydrocarbons and alkanes were the main factors affecting fume and VOCs concentrations,while the total sulfur content in asphalt was the key factor controlling H2S release. The fluorescence microscopy test further confirmed that a stable internal structure could suppress fume release from crumb rubber modified asphalt to a certain extent.
