Latex paints are widely used in residential and commercial indoor environments. The surface areas covered by the paints in these environments are relatively large. Thus, latex paints have the potential for having a major impact on indoor air quality (IAQ). A study was undertaken to develop methods for evaluating the impact of latex paint emission on IAQ. Small chamber experiments using stainless steel and painted and unpainted gypsum board substrates were conducted to determine the emission characteristics of latex paint. The emissions from the stainless steel were relatively short lived (3 to 4 days), whereas the emissions from gypsum board lasted for over 200 days. Because gypsum board is a common substrate for latex paint, all emission models were developed for the gypsum board substrates. The data from the small chamber tests led to the development of two empirical and two mass-transfer-based source emission models. Approximately 100 to 200 days of data were required to estimate the parameters required for the empirical models. Only 8 days of data were required to estimate the parameters for the mass-transfer-based models. The final models use paint formulation and mass transfer correlations to predict the emissions of the major individual volatile organic compounds emitted by latex paint.
乳胶漆广泛应用于住宅和商业室内环境。这些环境中涂料覆盖的表面积相对较大。因此，乳胶漆有可能对室内空气质量（IAQ）产生重大影响。开展了一项研究以开发评估乳胶漆排放对室内空气质量影响的方法。使用不锈钢以及涂漆和未涂漆的石膏板基材进行了小型舱室实验，以确定乳胶漆的排放特性。不锈钢的排放持续时间相对较短（3至4天），而石膏板的排放持续了200多天。由于石膏板是乳胶漆的常见基材，所有排放模型都是针对石膏板基材开发的。小型舱室测试的数据促成了两个经验模型和两个基于传质的源排放模型的开发。估计经验模型所需的参数大约需要100至200天的数据。估计基于传质的模型的参数仅需要8天的数据。最终模型使用涂料配方和传质相关性来预测乳胶漆排放的主要挥发性有机化合物的排放量。
