地板VOCs释放成分及浓度的实验研究

Experimental Study on Composition and Concentration of VOCs Released From Floorboard

通过液相色谱法测定实木地板、塑料地板、强化复合地板中13种醛酮类化合物的浓度,得出三类地板中各化合物含量信息。根据连续6 d化合物浓度变化,计算出13种化合物的挥发速率。分析得出,实木地板中甲醛和己醛含量最高,塑料地板中环己酮含量明显高于其他化合物,强化复合地板其初始散发速率小但增长快。实验研究为地板在使用过程中对于室内环境质量控制提供参考依据。

The concentrations of 13 aldehydes and ketones in VOCs released from wooden floor,plastic floor and reinforced composite floor were determined by liquid chromatography,and the content information of each compound in three kinds of floor was obtained.The volatilization rates of 13 compounds were calculated according to the concentration change of the compounds for 6 consecutive days.The results showed that the content of formaldehyde and hexaldehyde in VOCs released from wooded floor was the highest,and the content of cyclohexanone in VOCs released from plastic floor was obviously higher than that of other compounds.The initial emission rate of reinforced composite floor was small but the growth was fast.The experimental research provides reference basis for indoor environmental quality control in the process of floor use.
