小型环境试验舱的研制及性能研究

自制小型环境试验舱的体积为0．17m^3，用产生甲醛的标准气体方法检验试验舱的稳定性、准确性及精密性。结果表明，试验舱稳定，无吸附，且有95％的精确性。通过测定试验舱内木板中甲醛释放量及释放规律检验试验舱的应用性能，测得甲醛释放规律与文献研究结果一致，表明该试验舱应用性能良好，因此该实验舱可用于检测室内装饰装修材料中污染物质释放量及释放规律的研究。

Development of Small Environmental Chamber and Its Function

The authors made the small environmental chamber by oneselves,and its volume was 0.17m3,used quantitative formaldehyde to test the stability and accuracy and precision of the cabin.It could see that the chamber had good function and it got 95% of accu-racy.The authors also tested the formaldehyde emission quantities of artificial woodbased boards,the results reflected that the release rule of formaldehyde was right and the chamber was good forapplying.Therefore it could be use the small environmental chamber to study on the emissionquantities of pollutions from fitment materials.
