摘要/Abstract

摘要：

提出了一种新型的建筑板材内甲醛散发关键参数的处理方法，并进行了不同温度场作用下的实验研究。结果表明，温度可以明显促进板材内甲醛的散发，根据实验数据拟合得到K_m、C₀和D_m，三大参数随温度的变化规律验证了本文提出的新型处理方法；实验过程中，舱内浓度对甲醛挥发速率的抑制作用比温度对其的促进作用更加明显；本文提出的新型处理方法被证实是可行并且可靠的，可为板材内其他VOC气体散发参数的处理提供依据和参考。

Abstract:

A new method was proposed to calculate the key parameters of formaldehyde diffusion within building materials. In addition,the experimental study in different temperature was finished. The experimental results showed that temperature make obvious contribution to formaldehyde diffusion. K_m,C₀ and D_m were obtained by experimental data fitting and the relationship between three key parameters and temperature verify the new method. What's more,the inhibitory effect of formaldehyde concentration was more obvious than promoting effect of temperature on emission rate of formaldehyde. Last but not least,the new procession method proposed in this paper was proved to be feasible and reliable,providing help and reference for dealing with emission parameters of other VOCs.

Key words: temperature, processing method, diffusion, formaldehyde, porous media, mass transfer
