环境本底对环境测试舱测量装饰材料中游离甲醛释放量影响的研究

Study on the Impacts of Background Value of Air for the Measurement of Content of Free-Formaldehyde Released in Decorative Materials Using Environmental Test Chamber

文章对QHX-Ⅲ型1 m3环境测试舱测量装饰材料中游离甲醛时,室内外不同温度条件下,环境本底对测量材料中游离甲醛释放量的影响进行了探讨,直接引入室外空气时,本底值呈无规律变化,直接引入室内空气时,本底值随室内温度的上升,呈线性上升趋势。因此,必需对引入环境测试舱空气进行净化处理。

In this study,we are discussing the impacts of background value of indooroutdoor air in different temperature condition for the measurement of content of free formaldehyde released in decorative materials using the type of QHX-Ⅲ 1 m3 environmental test chamber.When outdoor air are directly draw into the chamber,the background value of air is irregular changing,and when indoor air are directly draw into the chamber,it trends linear ascendant as value of the indoor temperature rise.Therefore,it is necessary to purify the air of introduce the environment test chamber.
