醇酸调和漆中甲醛释放规律研究

Study on Formaldehyde Emissions from Alkyd Ready Mixed Paint

以目前国内市场上广泛使用的醇酸调和漆为研究对象,利用按照ASTME1333-1996标准自行设计的环境测试舱,采用酚试剂比色法,检测醇酸调和漆样品涂刷后空气中甲醛浓度值随时间的变化规律,计算出相应的甲醛释放率,分析甲醛释放特征,并考察环境温度、空气置换率、环境相对湿度等主要环境因子对其影响,同时,建立了甲醛释放率的实测曲线,为建立预测装饰装修材料对室内空气质量影响的评价体系提供可靠数据依据。

Formaldehyde emission from alkyd ready mixed paint is studied in this paper. We measured the formaldehyde concentration consecutively in an environmental testing chamber that is designed by ourselves according to ASTM E1333- 1996 standards. The test uses the phenol reagent method, detects the change regularity of formaldehyde concentration in the air with the time after painting alkyd ready mixed paint, computes the corresponding Formaldehyde emission rate and analyzes the characteristics of formaldehyde emission. Then, the test studies the effect of some environment factors on it, including environmental temperature, rate of air conversion and environmental relative humidity. In this paper, we base on the curse of formaldehyde emission rate to perfect the evaluate system of indoor decorating and refurbishing materials.
