摘要:
为提高轨道交通车辆的车内空气质量，以客车常用的阻尼涂料和腻子湿料为试样，进行吸附效应试验和脱附效应试验，实时监测并记录环境测试舱内的TVOC(总挥发性有机化合物)质量浓度，分析阻尼涂料对环境舱中TVOC的吸附效应，研究吸附后的阻尼涂料在不同通风量和温度下对TVOC的脱附效果。研究结果表明：阻尼涂料对TVOC具有较强的吸附效应；在对吸附TVOC后的阻尼涂料进行脱附时，通风量越大、脱附温度越高脱附效果越好。
Abstracts:
To improve the interior air quality of rail transit vehicle, the damping coating and acrylic wall putty commonly used on passenger compartment are taken as specimens to conduct adsorption and desorption effect tests. The TVOC (total volatile organic compounds) mass concentration in the test chamber is monitored and recorded in real time to analyze the damping coating adsorption effect of TVOC in the environmental chamber. For the damping coating that has absorbed TVOC, the desorption effects at different ventilation volumes and under different temperatures are studied. Research results show that damping coating has strong adsorption effect of TVOC; when the desorption is carried out on the damping coating that has absorbed TVOC, the higher the ventilation volume and the desorption temperature, the better the desorption effect.
