摘要
目的了解兰州市售人造板材甲醛释放量。方法于2004年5月采集兰州市售的42种不同品牌的人造板材,其中细木工板16种,胶合板15种,装饰单板贴面胶合板11种,采用GB/T17657-19994.12《人造板及饰面人造板理化性能试验方法》中甲醛释放量干燥器法进行甲醛释放量的测定。结果符合E1级(干燥器值≤1.5mg/L,可直接用于室内装修)的人造板材有9种,占样品总数的21.4%,E2级(干燥器值≤5.0mg/L,饰面处理后允许用于室内装修)的有20种,占总数的47.6%,其余均为不合格产品。甲醛释放量排序为胶合板(7.58mg/L)>细木工板(4.88mg/L)>装饰单板贴面胶合板(2.85mg/L),差异有统计学意义(F=4.193,P<0.05)。结论兰州市售人造板材甲醛释放量有超标情况,应引起有关部门关注。
Objective To investigate the quantity of formaldehyde released by artificial wood-based boards sold in Lanzhou. Methods Formaldehyde quantity released by three kinds of artificial wood-based boards （42 samples） were determined with desiccator method. Results Among 42 samples, 9 artificial wood-based boards were E1-level （21.4%）, 20 E2-1evel （47.6%）, the others disqualification （31%）. A significant difference （0.01 〈P〈0.05） was seen among the quantity of formaldehyde released by the three kinds of artificial wood-based boards and the plywood ranked the first. Conclusion In some of three kinds of artificial wood- based boards sold in Lanzhou, the formaldehyde emission quantity exceeded the national standards of China. More attention should be paid to the status by related administration.
