室内用品中发挥性有机物的挥发模式

选择不同形态的室内用品，包括壁纸、地板蜡、调和漆、彩喷涂料、空气清新剂和萘丸６种室内用品，在选定的温度、湿度、空气交换率等环境条件下，做测试室模拟试验。用四种挥发模式对挥发性有机物总浓度－时间关系做回归分析，同时计算出表面挥发速率。结果表明，对于像调和漆、彩呀涂料这样的液态高挥发溶剂型材料，四种挥发模式结果是一致的。而对于像壁纸、地板蜡和萘丸等固态低挥发型材料，考虑了吞吐效应的回归模式和经验模式优

Emission model of volatile organic compounds from materials used indoors]

Various materials, such as wall-paper, floor-wax, paint, multicolor wall-coat, air freshener and mothball were experimented in a simulated test chamber under constant selected temperature, humidity and air exchange rate. The relation between the total VOCs concentration and time was regressed by four emission models and the surface emission rate was calculated. The regressed results indicated the similarity among four emission models for the liquid materials with volatile-solvent such as paint and multicolor wall-coat. But for low volatile solid materials, such as wall-paper, floor-wax, mothball, the sink model and the empirical model were better than the dilution model and vapor pressure model. Only for air freshener, it was improper to the total VOCs concentration as a parameter.
