摘要：通过对干燥器法甲醛释放模型的分析 ,探讨并验证影响木制品甲醛释放量的因素 ,分析比较 10L与 4 0L干燥器法测定值的关系。结果表明 :该甲醛释放模型较好地表述了干燥器法中影响甲醛释放的因素 ,甲醛浓度与水体积成反比 ;随水表面积增加 ,甲醛浓度逐渐增加。对于边部面积与表面面积之比相同的试样 ,4 0L与 10L干燥器法甲醛测定值之间存在很好的一元线性关系 ,4 0L干燥器值约为 10L的 3 5～ 3 9倍 ;但对于表面甲醛释放速率不同的试样 ,如果不封边或边部面积与表面积之比不同 ,则 10L与 4 0L干燥器法没有可比性。试样边部释放甲醛的速率明显高于试样表面。对于刨花板和中密度纤维板 (MDF) ,边部释放速率约为表面的 2倍 ;对饰面MDF ,87%以上的甲醛从边部释放 ;对于胶合板 ,约 4 0
Through analyzing formaldehyde release equation in desiccator, factors influencing formaldehyde release from wood products were discussed and checked. The relationship of the values was also compared determined by 10 L glass desiccator and 40 L acrylic desiccator method. The results showed that the formaldehyde release equation accurately represented the behavior of formaldehyde release in desiccator. The formaldehyde concentration was inverse ratio to the water volume and formaldehyde concentration gradually increased while the surface area of water increasing. For samples with same ratio of edge area to surface area, a good linear relationship was existed between the two desiccator methods, and the desiccator values determined by 40 L desiccator method was 3.5～3.9 times of that determined by 10 L desiccator method. But for samples with different ratio of edge area to surface area, there was no comparability between 10 L and 40 L desiccator values. The formaldehyde emission rate from the edge was much faster than the surface of the panel. For particleboard and MDF, the formaldehyde emission rate from the edge was about double of that from the surface of panel. For DMDF, more than 87% formaldehyde emitted from the edge of the panel. For plywood, about 40% formaldehyde emitted from the edge of the panel.
