家庭室内装修后甲醛污染现状及其变化规律探讨

Discussion on Situations and Changing Patterns of Formaldehyde Pollution in the Decorated Room

探讨家庭室内装修后空气中甲醛污染现状及其变化规律。按照室内装修后时间长短不同及温度的变化进行跟踪检测。经过装修的居室室内空气中的甲醛浓度均高出(甚至远远高出)楼房竣工验收时的浓度,说明甲醛污染主要由装修引起,装修后装饰材料(板材等)仍能释放甲醛,并造成室内甲醛超标,随着时间的推移,室内甲醛浓度逐渐降低。但是,随着夏季气温的升高,冬季装修的居室甲醛浓度会急剧升高,造成室内空气严重的"二次污染"。

The situations and the changing patterns of formaldehyde pollutions in the air of the indoor decoration are probed. The formaldehyde concentration indoor is tracked and measured according to the temperature and time. The formaldehyde concentration in the decorated rooms is much higher than that of completion acceptance, which proves the formaldehyde pollutions are caused by the indoor decoration and the material used in decoration which can continue to release formaldehyde. As time goes by, the formaldehyde concentration will decrease, but with the rise of the temperature in summer, the concentration of the decorated room in winter will have a sharp rise, which leads to a second pollution of the indoor air.
