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附进行了初步研究。人造木板甲醛释放特性研究表明:温度和时间是影响甲醛释放的重要因素。试验板材中甲醛释放速度和释放量:三夹板>高密度板。人造木板甲醛释放速度与释放量均与温度明显成正相关。做甲醛浓度与温度的相关性分析,相关系数都在0.90以上,但斜率变化与时间有明显关系,三夹板浓度与温度的线性关系曲线的斜率从1h至11h由41.86降到14.25,高密度板则从181.19降到49.45。说明板材甲醛释放率在前期受温度影响较大;也说明温度对高密度板影响较大,对三夹板影响较小。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。在培养箱内测的数据显示:放入粉状活性炭前后24小时内最大浓度差异为0.77mg/m3,放入中颗粒活性炭为0.15mg/m3,放入大颗粒活性炭为0.08mg/m3。

This article mainly the formaldehyde release characteristic and the activated charcoal has conducted the preliminary study to the man-made plank in to the formaldehyde adsorption. The man-made plank formaldehyde release characteristic research indicated that, The temperature and the time are affects the formaldehyde release the important attribute. In experimental plate formaldehyde release rate and release quantity: high density board. The man-made plank formaldehyde release rate and the release quantity obviously become with the temperature is being connected. Makes the formaldehyde density and the temperature relevant analysis, the correlation coefficient all above 0.90, but the slope deviation and the time have the obvious relations, the density and the temperature linear relations curve slope imitates 1h --41.86 to fall to 14.25, high density boards from 181.19 falls 49.45. Explained the plate formaldehyde release rate is been bigger in the earlier period the temperature influence; Also explained temperature to high density board influence bigger, is smaller to the influence. 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 raises the data display which in the box measured: Puts in around the powdery activated charcoal in 24 hours the greatest density difference is 0.77mg/m3, puts in the pellet activated charcoal 0.15mg/m3, puts in the big pellet activated charcoal 0.08mg/m3 .
