从3月8日至4月29日对某栋新建建筑的五个办公房间的甲醛浓度在安装地板、涂刷内墙涂料及安置家具共三个装饰装修阶段进行了现场采样分析,并对五个办公房间的环境温度和换气次数进行了测试。结果分析表明:(1)在建筑室内装饰装修设计过程中,对建筑室内甲醛浓度贡献率的大小排序依次为:家具>地板>内墙涂料,其中家具对室内甲醛浓度的贡献率为49.6%,地板对室内甲醛浓度的贡献率为36.3%,涂料对室内甲醛浓度的贡献率为14.1%;(2)同一建筑中房间局部微环境对甲醛浓度有较大的影响,在众多影响因素中,温度和房间换气量对甲醛的浓度影响较大。
From March 8 to April 29 on a new building five office space formaldehyde concentration in the installation of floor, brushing interior wall paint and a total of three phases of furniture decoration site sampling analysis, and five A test of the room temperature and ventilation. The results show that: (1) In the interior decoration design process, the order of the contribution rate of formaldehyde concentration in building interior is: furniture> floor> interior wall paint, in which furniture contributes 49.6% of indoor formaldehyde concentration, The contribution rate of floor to indoor formaldehyde concentration is 36.3%, and the contribution rate of paint to indoor formaldehyde concentration is 14.1%. (2) In the same building, the local microenvironment has a great influence on the formaldehyde concentration. Among the many influencing factors, the temperature And room ventilation on the concentration of formaldehyde greater impact.
