板式家俱甲醛释放与环境温度定量关系研究

目的]探讨板式家俱甲醛释放与室内温度的相关性，并建立它们的定量关系。方法]在关闭办公室所有门窗后的第2天，以室外空气测量为参比进行对照试验，并测量室内空气甲醛含量，同时测定空气的温度、湿度和大气压。结果]冬季室内空气的甲醛超标率为20％，春季室内空气的甲醛超标率为36％，夏季室内空气的甲醛超标率为84％，秋季室内空气的甲醛超标率为70％。室内甲醛释放与环境温度成正比。线性回归、对数回归、一元二次回归、指数回归的相关系数分别为0．7605、0．9624、0．9686和0．9871，甲醛浓度与环境温度的定量关系是指数回归或对数回归和一元二次回归。结论]在一定范围内，室内甲醛浓度与环境温度是一元二次方程关系。

Study on the Quantitative Relationship between Formaldehyde Released from Panel Furniture and Environmental Temperature

Objective] The study aimed to discuss the correlation between formaldehyde released from panel furniture and room temperature and set up their quantitative relationship.Method] On the 2nd day since closing all the doors and windows of office,the controlled experiment was performed with reference to measuring outdoor air.And then the formaldehyde content in room air was measured and the temperature,humidity and atmospheric pressure of air were measured at the same time.Result] The over standard rate of fo...
