整车VOC的挥发规律研究

Study on VOC Volatilization Law of Vehicle

主要研究整车VOC的挥发规律,即对于同一台车,不同的下线放置时间对整车醛类、苯系物结果的影响。实验结果表明随着下线时间的增加,甲醛、乙苯和苯乙烯的浓度随着下线时间的增加而升高,苯、甲苯、二甲苯、乙醛随着下线时间的增加而降低。各VOC浓度变化速率和初始浓度呈线性正相关。

The influence of the same car on the results of aldehydes and benzene series in the vehicle at different offline placement time was studied,and the volatilization law of VOC in the vehicle was explored.The results showed that the concentration of formaldehyde,ethylbenzene and styrene increased with the increase of the off-line time,while the concentration of benzene,toluene,xylene and acetaldehyde decreased with the increase of the off-line time.The change rate of each VOC concentration was linearly positively correlated with the initial concentration.
