本文主要对人造木板中甲醛释放特性和甲醛的去除方法(美国INTERSCAN公司生产的4160型甲醛分析仪测定法)进行了研究。人造木板甲醛释放特性研究表明:人造木板甲醛释放速度与释放量均与温度明显成正相关,随着时间的延长,空气中的甲醛浓度增高,在密闭环境中会达到一个相对稳定值。这说明温度和时间是影响甲醛释放的重要因素;另外甲醛释放速度和释放量与人造木板的特性(如密度、粘合剂的类型及含量等)有关。试验板材中甲醛释放速度和释放量:三夹板>高密度板。对甲醛的去除方法研究表明:在同一种板材内放入不同的活性炭,甲醛的去除效率差别很大。去除效率:粉状活性炭>中颗粒活性炭>大颗粒活性炭。

The main characteristics of artificial wood, formaldehyde and formaldehyde released by the removal method (4160 - U.S. InterScan production companies formaldehyde analyser measurement) conducted research. Studies show that artificial wood formaldehyde release characteristics : speed and artificial wood formaldehyde emissions are released into the temperature is clearly related, with the extension, the formaldehyde concentrations of the air rising in a confined environment will reach a relatively stable value. This shows temperature and time is an important factor affecting the release of formaldehyde; Also formaldehyde emissions and the release of speed and the artificial nature of wood (such as density, the type of adhesive and content, etc.). Test plate, and speed the release of formaldehyde emissions : three things "high Miduban. The study shows that the removal method to formaldehyde : a plate of them at the same different activated charcoal, the removal efficiency varies greatly formaldehyde. Removal efficiency : powder activated charcoal "particles activated charcoal" big particles activated charcoal.
