【摘要】 完善木质复合材料中甲醛释放量的检测方法对我国人造板行业的发展具有重要意义。本研究采用气候箱法、40L干燥器法、9—11L干燥器法和穿孔萃取法测定细木工板、刨花板、中密度纤维板、强化木地板和实木复合地板中甲醛释放量，对比分析实验结果，确定最佳检测方法。通过对所选材料的测试结果进行分析，本研究得出以下结论：(1)对细木工板而言，9-11L干燥器法的测试结果较其它方法的测试结果好。(2)对刨花板和中密度纤维板而言，穿孔萃取法和9-11L干燥器法的实验结果较其它方法的测试结果好。(3)对强化地板而言，9-11L干燥器法和40L干燥器法的测试结果较其它方法的测试结果好。(4)对实木复合地板而言，9-11L干燥器法的实验结果较其它方法的测试结果好。更多还原

【Abstract】 It is over important for the development of wood-based panel industry in China to improve testing methods which are used to measure formaldehyde emission of wood-based composite. Measurement of formaldehyde emission with different wood-based composites such as blockboard, particleboard, MDF, laminate floor and layer parquet through 40L desiccator method, 9-11L desiccator method, perforator method and chamber method were studied in this paper. The optimum testing method is acquired through comparatively analyzing the experimental results. The researching results are listed as follow:(1) Comparatively analyzing four testing methods that are used in the research, it can come to conclusion that the experimental results of 9-11L desiccator method is best for measuring formaldehyde emission of blockboard.(2) As far as particleboard and MDF are concerned, the experimental results of 9-11L desiccator method and perforator method are better than that of others methods.(3) The conclusion of laminate floor is that 9-11L desiccator method and 40L desiccator method whose experimental results are better than that of other methods is suggested to measure formaldehyde emission of laminate floor.(4) According to the experimental data of MDF, it can draw a conclusion that the experimental results of 9-11L desiccator method are the best.更多还原
