摘要
为研究室内建材有机挥发物(VOCs)的散发情况,本文给出开放小室测定刨花板VOCs散发特性参数(刨花板内初始VOCs平均浓度、分离系数)和对流传质系数的模型及计算方法,并以黑龙江省某两厂生产的刨花板P1和P2为例,给出其释放参数的估计,讨论温度对该种板材释放参数的影响。本文可为建材筛选、VOCs散发性能评价、室内空气质量评定与预测提供一种方法。
Volatile organic compounds（VOCs）emitted from building materials can influence indoor air quality.Based on small ventilated chamber,a method for measuring the VOCs emission characteristic parameters（including the mean initial concentration,the partition coefficient）of particle board and the convective mass transfer coefficient was presented.In this paper,parameters estimation of particle board P1 and P2 from Heilongjiang were calculated,and the relationships between the VOCs parameters of the board and temperature were discussed.The testing methods and measurements of the model can be used to guide the selection of building materials and for evaluating the emission characteristics of building materials,evaluating and forecasting indoor air quality.
