室内空气中甲醛浓度与人造板使用量的关系

Relationship between Formaldehyde Concentration of Indoor Air and Quantity of Wood-based Panels

研究了材料甲醛释放量及设置率、换气次数、室内温度和湿度与室内空气中甲醛浓度的关系。在现有的材料设置率和环境条件下,为了使空气中甲醛浓度≤0.10 mg/m3或≤0.08 mg/m3,材料的甲醛释放量必须≤0.5 mg/L或≤0.3 mg/L。

A series of experiments were conducted to evaluate how the formaldehyde concentration indoors could be affected by some environmental conditions. The factors to he tested included the formaldehyde emission of panel materials,panel setting coefficient（panel quantity to room volume）, times of air exchange, and indoor temperature and humidity. Results found that under the current panel setting coefficient of 0. 6 m^2/m^3 and environmental conditions, to make the indoor formaldehyde concentration of a room attain 40.10 mg/m^3 or 40.08 mg/m^3 , the formaldehyde emission of panels should be less than 0.5 mg/L and 0. 3 mg/L respectively.
