温湿度对典型家具材料甲醛散发的影响研究

摘要

为了研究环境参数对室内家具中甲醛的散发影响，采用环境舱实验研究了温度和相对湿度对4种典型家具（复合地板、长条座椅、橱柜、壁柜）材料中甲醛散发的影响．给出了释放速率E的定义，通过回归分析表明释放速率的自然对数与温度的变化成强线性相关关系（相关系数r＝0.9936～0.9995）．研究结果表明：材料样品中甲醛的散发随着温度的升高和湿度的增大而散发加强；在高温高湿度环境下甲醛的散发更加强烈．研究结论对南方热湿地区和北方地板采暖房间室内甲醛污染的防治和室内装修设计提供了指导；对房间通风空调系统的热湿和污染物的处理优化设计提供参考．%In order to study the diffusion rules of formaldehyde in indoor furniture , it studies the tempera-ture and relative humidity effects for formaldehyde emission in the four typical materials ( composite floor , bench seat , cabinet , wall cabinet ) by the use of environmental chamber experiments .The release rate E was defined and the close linear correlation was found between the natural logarithm of temperature change and the release rate by regression analysis ( correlation coefficient r=0.993 6~0.999 5 ) .The results show that formaldehyde emission rate will be strengthened with the increase of temperature and hu -midity in sample materials .And the formaldehyde emission will be greater under the high-temperature and high-humidity environment .The results can be applied to prevent indoor pollution and have signifi-cance for indoor design in hot and humid southern areas and in heating northern zones .It also has refer-ence for the optimization of treating heat , moisture and contaminants of room ventilation and air condition-ing system .
