摘要
针对目前室内装修常用的高密度人造木地板,采用大环境舱模拟实际室内空气环境研究了甲醛的散发,并对处于稳定散发期的木地板研究了环境因素对其甲醛及VOCs散发的影响,同时作了VOCs化学成分的检测。研究结果发现:高密度人造木地板的甲醛散发具有规律性,甲醛散发在几小时内达到最大值后逐渐衰减直到趋于稳定值;环境因素对稳定散发期的木地板的甲醛及VOCs的散发有较大影响;受试木地板除散发甲醛外还散发多种VOCs,它们主要是芳香族挥发性有机化合物。
Formaldehyde and VOCs emissions from a type of 12 mm high density wood-based floorboard, used commonly, were studied in full-scale environment chamber which could model realistic indoor environment. It was found that formaldehyde emission presented law： formaldehyde concentration reached its maximum within several hours and began to fall till steady value; it was notable that impacts of environmental factors on emissions from formaldehyde and VOCs in steady release phase; formaldehyde and manifold VOCs were found in the volatile from the high density wood-based floorboard tested and they were manly volatile aromatic hydrocarbons.
