本文主要对人造木板中甲醛释放特性和活性炭对甲醛的吸收进行了初步研究。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有关。试验板材中甲醛释放速度和释放量:三夹板>高密度板。活性炭对甲醛的吸附研究表明: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。比表面积越大去除效果越好。去除效率:粉状活性炭>中颗粒活性炭>大颗粒活性炭。在100cm×50cm×40cm的培养箱内测的数据显示:在放入粉状活性炭前后24小时内最大浓度差异为0.77mg/m3(35℃,第10小时),放入中颗粒活性炭为0.15mg/m3(35℃,第2小时),放入大颗粒活性炭为0.08mg/m3(35℃,第6小时)。

The article mainly the formaldehyde release characteristic and the activated charcoal has conducted the preliminary study to the man-made plank in to the formaldehyde absorption. The man-made plank formaldehyde release characteristic research indicated that, The man-made plank formaldehyde release rate and the release quantity obviously become with the temperature is being connected, along with time lengthening, in the air formaldehyde density advances, can achieve relatively in the airtight environment . This indicated the temperature and the time are affects the formaldehyde release the important attribute; Moreover the formaldehyde release rate and the release quantity and the man-made plank characteristic concerns. In experimental plate formaldehyde release rate and release quantity: high density board. The activated charcoal indicated to the formaldehyde adsorption research that, Puts in the different activated charcoal in the identical kind of plate, the formaldehyde removes the efficiency difference to be very big. The relative surface product more greatly removes the effect to be better. Removes the efficiency: In powdery activated charcoal pellet activated charcoal big pellet activated charcoal. In 100cm×50cm×40cm the raise box measured data display that, In puts in around the powdery activated charcoal in 24 hours the greatest density difference is 0.77mg/m3 (35℃, 10 hours), puts in pellet activated charcoal 0.15mg/m35 ℃, 2 hour), puts in big pellet activated charcoal 0.08mg/m35 ℃, 6 hour).
