摘要
目的对杭州市市场上销售的木质板材的甲醛释放量进行调查并对其释放规律进行研究。方法选取刨花板、三夹板、细木工板、强化地板4种木质板材采用小型环境测试舱平衡浓度法进行甲醛释放量的测定。结果A级木质板材占40%,B级占50%,C级占10%,并且对不同品种木质板材的甲醛释放量进行比较,甲醛释放量由低到高依次为强化地板<刨花板<细木工板<三夹板,结果经统计分析,差异具有显著性(P<0.05)。结论木质板材甲醛释放量的调查结果不容乐观,并且不同品种的木质板材的甲醛释放量是不同的。
Objective To investigate the formaldehyde emission rate of wood-based materials sold in Hangzhou and to ana-lyze its emission characteristics.Methods Four kinds of wood-based materials were selected and the formaldehyde emission rates were determined by applying the balancing concentration method of small environmental test chamber and the emission rates of different kinds of the materials were compared.Results A-level wood-based materials were of40%,B-level50%and C-level10%of the whole.The formaldehyde emission rates of these different kind of wood-based materials were significantly different (0.01<P<0.05).Conclusion The result of the investigation showed that the formaldehyde emission rates of wood-based materials were not satisfactory,and the formaldehyde emission rates of various kinds of wood-based materials were different.
