室内装饰装修材料VOC散发研究
Research on VOC emission of indoor decoration materials
摘要：
新装修建筑室内的挥发性有机化合物(VOC)严重危害人体健康,各种装饰装修材料是VOC散发的主要源头。提出了一个室内污染物预评价模型,可根据施工信息和建材信息高效拟合出室内VOC浓度曲线。设计实验对模型进行验证,通过环境舱法研究了温湿度对不同装饰装修材料的散发影响,并结合实测案例对建筑室内甲醛浓度进行预测。研究结果表明,该模型能够准确描述干湿材料的污染物散发,且通过模型计算得到的拟合曲线趋势与实测数据贴合良好,拟合值与实测值的相对误差控制在30%以内,对于预测新装修室内VOC浓度具有一定意义。
Abstract：
Volatile organic compound (VOC) in newly renovated buildings is a serious threat to human health, and various decoration materials are the main sources of VOC emission. A pre-evaluation model of indoor pollutants is proposed, which can efficiently fit the indoor VOC concentration curve according to the construction information and building material information. The model is verified by design experiments, and the influence of temperature and humidity on the emission of different decoration materials is studied by the environmental cabin method, and the indoor formaldehyde concentration of the building is predicted based on the measured cases. The results show that the model can accurately describe the pollutant emission of dry and wet materials, and the trend of the fitting curve calculated by the model is in good agreement with the measured data, and the relative error between the fitting value and the experimental value is controlled within 30%, which has certain significance for predicting the concentration of VOC in the newly renovated buildings.
