建材中挥发性有机物的快速评价

Rapid Determination of Volatile Organic Compounds in Building Materials

介绍了简便快速地对建筑室内装修材料中挥发性有机化合物的测定方法。使用纯木材,利用热分析和气相色谱法(GC)进行了实验研究。结果表明,该方法能迅速地测定木材中的挥发性有机化合物,木材中产生的挥发性有机化合物组分的量从40℃到120℃,从3分钟到22分钟没有变化。对壁纸中挥发性有机化合物总量进行了测定,该方法也是快速有效的。

A rapid measuring method for VOCs in decorative building materials was developed using pure wood, 0thermogravimetry and gas chromatography . Tesitng results showed that this method could rapidly determine VOCs in wood and found the amount of VOCs emitted from wood did not vary at 40℃ to 120℃ in 3 min to 22 min. It was also quick and effective for determination of the total amount of VOCs in wallpapers.
