Abstract_Chinese:家具和装修建材是室内挥发性有机物(VOC)的主要污染源，会造成室内空气质量低劣，对人体健康、室内舒适性和工作效率产生严重影响．研究干建材VOC散发特性对控制室内污染物浓度、提高空气品质具有重要意义．干建材中VOC的散发过程可分为：VOC在干建材内部的扩散传质过程和干建材表面的对流传质过程．从传质理论的角度来看，干建材VOC的散发特性可由3个关键参数表征，即初始可散发浓度C_m,0、干建材内VOC的扩散系数D_m和分离系数K．简要总结了干建材VOC散发关键参数经典测试方法(如流化床脱附法、常温萃取法、湿杯法及双舱法等)，并分析了各方法的局限性，其中详细介绍了直流舱浓度轨迹法(直流舱C-history法)．详细介绍并评价了循环密闭/通风散发法与连续升温-多气固比(CTR-VVL)法．总结了采用不同测试方法(直流舱C-history法、CTR-VVL法、多次散发回归法等)所测得的干建材VOC散发关键参数的实验数据．总结了不同关键参数受温度、湿度影响的理论模型，并对比分析了前人数据与不同模型的拟合结果．最后，还分析了干建材VOC散发研究方面存在的不足及进一步研究的相关建议．
Abstract_English:Furniture and decorative materials are the main sources of indoor volatile organic compounds (VOC), which cause poor indoor air quality and have a serious impact on human health, indoor comfort, and work efficiency. It is important to study the VOC emission characteristics of dry building materials for controlling indoor pollutant concentration and improving air quality. With regard to dry building materials, the VOC emission process involves the diffusion mass transfer process of VOC inside the materials and the convective mass transfer process on the surface of materials. Based on the mass transfer theory, the characteristics of VOC emission from dry building materials can be reproduced by three key parameters: initial emission concentration C_m,0, diffusion coefficient D_m, and partition coefficient K of VOC in dry building materials. We briefly summarize the classical testing methods for the key parameters of such VOC emission (such as fluidized bed desorption method, ambient temperature extraction method, wet cup method, and twin-chamber method), and analyzed the limitations of these methods. We also introduce and describe the ventilated chamber concentration history (ventilated chamber C-history) method in detail. Further, we introduce and evaluate the alternately airtight/ventilated emission method and continuous temperature rising-variable volume loading (CTR-VVL) method in detail. The key parameters of VOC emission from dry building materials measured by different test methods (e.g., ventilated chamber C-history, CTR-VVL, and multi-emission/flush regression method) were analyzed and summarized. The theoretical models of different key parameters affected by temperature and humidity were summarized and fitted with previous data. Finally, the shortcomings in the research of VOC emission from dry building materials and suggestions for further research are proposed.
