Abstract

Furnishing textile materials may be a source of formaldehyde (CH2O) re-emission if this compound is present in the environment. In the examinations performed the effect of temperature (23 degrees C, 35 degrees C) and air humidity (RH: 45%, 85%) upon CH2O re-emission from curtain materials was determined. The source of CH2O emission was particle board. CH2O emission was determined in small glass chambers (13.08 dm3) in controlled conditions, one air exchange per hour at loading factor of 1 m2/m3. The results of these examinations showed that the effect of temperature and humidity upon CH2O adsorption and desorption was different. Increase of temperature from 25 degrees C to 35 degrees C caused increase of the magnitude and rate of CH2O re-emission and the phenomenon intensified at high air humidity.

摘要

如果环境中存在甲醛（CH₂O），装饰性纺织材料可能会成为甲醛再次释放的来源。在进行的检测中，测定了温度（23摄氏度、35摄氏度）和空气湿度（相对湿度：45%、85%）对窗帘材料中甲醛再次释放的影响。甲醛释放源为刨花板。在可控条件下，于小型玻璃试验箱（13.08立方分米）中测定甲醛释放量，装载系数为1平方米/立方米时每小时换气一次。这些检测结果表明，温度和湿度对甲醛吸附和解吸的影响有所不同。温度从25摄氏度升至35摄氏度会导致甲醛再次释放的量和速率增加，且在高空气湿度下该现象会加剧。
