摘要
利用环境测试舱模拟不同试验条件,采用跟踪监测环境测试舱内空气中污染物浓度的方法,对细木工板中甲醛释放特征进行研究,并结合试验数据及相关标准引入模糊综合评价方法对细木工板中甲醛释放进行评价,建立室内甲醛散发模型。结果表明:细木工板中甲醛释放在很短的时间内迅速上升达到峰值,然后相对缓慢的逐渐衰退,最后趋于稳定,总体呈现非简单线性相关性;模糊评价模型可以有效反映出细木工板的结构、温度、相对湿度和空气交换率对细木工板中甲醛释放浓度的影响,从而实现综合分析量化;改善通风条件,增加空气交换率,是有效的降低细木工板中甲醛释放对室内空气的不良影响的方法;同时得出室内无净化装置时室内甲醛散发模型d Cidt=(1-Fb)u C0+SCVmu C1。
Formaldehyde emissions from block board were studied by measuring their concentration consecutively in an environmental testing chamber which to simulate different test conditions. At the same time a fuzzy evaluation was built to evaluate the effect of formaldehyde from block board based on the experimental data and national standards,establishment of indoor formaldehyde emission model. The results showed that formaldehyde emissions from block board in a very short period of time rised rapidly to the peak,and then relatively slow declined gradually,finally tended to be stable,overall presented a simple linear correlation. Fuzzy evaluation model could effectively reflect the block board structure,temperature,relative humidity and air exchange rate on the emission of formaldehyde concentration,thus realizing the comprehensive analysis to quantify. To improve the ventilation conditions,increasing the rate of air exchange were effective in reducing the emission of formaldehyde in indoor air of the adverse effects of the method. At the same time no indoor purification device of indoor formaldehyde emission model wasd Cidt=( 1- Fb) u C0+SCV- mu C1.
