摘要
目的探讨装修后居室室内空气中甲醛浓度随时间的变化规律。方法于2004年3—8月选择装修材料不同的2套新装修住宅,采用盐酸副玫瑰苯胺比色法,跟踪分析呼和浩特市2套居民新装修房屋室内空气甲醛含量。结果铺复合木地板的A房空气中甲醛浓度比铺耐磨砖地板的B房空气中甲醛浓度约高17%;从装修完毕起,至少要经过6个月,室内空气中甲醛浓度才基本降至符合国家标准的水平;在连续监测过程中也发现,若室温升高,室内空气中甲醛浓度也会略有上升。结论复合木地板释放的甲醛不容忽视;装修后6个月,室内空气中甲醛浓度才能降到容许范围。
It aims to explore the timing change law of formaldehyde concentration in the air of newly decorated living room. Through compared with the two suite of newly decorated apartments with different decoration materials from Mar. to Aug. 2004, adopted with pararosaniline hydrochloride aniline colourimetry, the track analysis on formaldehyde concentration in the air of newly decorated living room are made. The results show that formaldehyde released from the compound wooden floor can not be neglected, only six months later after dec.oration, the concentration of formaldehyde in the air of room can be reduced to the permitted scope.
