As the Recycling of wood waste becomes more important each year, wood products that contain urea-formaldehyde resins gained more attention due to the release of formaldehyde and other chemicals which have a critical impact on humans health and the environment. In this study, the hydrolysis of wood wastes from a French furniture industry was studied under different controlled conditions (temperature/pressure, steam ratio). An original on-line method to measure the emission of formaldehyde and ammonia using a FTIR spectrometer and a dilution system was applied successfully in this study. The effect of operatory conditions on formaldehyde and ammonia released is discussed. A mathematical model was also introduced to model the behavior of the ammonia and formaldehyde emission in the hydrolysis of wood waste.
随着每年对木材废料的回收再利用变得越来越重要，含脲醛树脂的木制品因其释放的甲醛和其他化学物质而受到更多关注，这些物质对人类健康和环境有重大影响。在这项研究中，在不同的控制条件（温度/压力、蒸汽比）下研究了法国家具工业的木材废料的水解。本研究成功地应用了一种使用傅里叶变换红外光谱仪和稀释系统在线测量甲醛和氨排放的原始方法。讨论了操作条件对甲醛和氨释放的影响。还引入了一个数学模型来模拟木材废料水解过程中氨和甲醛排放的行为。
