地采暖用木质地板甲醛释放限量指标探讨
|
摘要
利用1 m3气候箱法测定地采暖用实木复合地板和浸渍纸层压木质地板在23、30、35℃条件下的甲醛释放量,结果表明:1)两种地采暖用木质地板的甲醛释放量均随着测试温度的升高而增加;2)按照GB18580-2017《室内装饰装修材料人造板及其制品中甲醛释放限量》方法,甲醛释放量检测结果不超过0.06mg/m3的样品,在30℃时的甲醛释放量也能达到标准限量要求。建议地采暖用木质地板的甲醛释放限量指标要求修订为≤0.06 mg/m3。
According to the national standard GB 18580-2017:"Indoor decorating and refurbishing materials-Limit of formaldehyde of wood-based panels and finishing products", formaldehyde emissions from samples of engineered wood flooring and laminate flooring for ground with heating systems were measured using 1 m3-chamber method at 23 ℃, 30 ℃ and 35 ℃, respectively. Results showed: 1) with temperatures rising, formaldehyde emissions from wood-based flooring increased; 2) the samples with less than 0.06 mg/m3 of formaldehyde emissions at 23 ℃ released less than 0.124 mg/m3 formaldehyde emissions at temperature 30 ℃, which met the requirements of GB 18580-2017. Therefore, it was suggested that specification of formaldehyde emission limit for wood-based flooring for ground with heating systems be revised to less than 0.06 mg/m3 at 23 ℃.
