摘要

三聚氰胺浸渍纸装饰中密度纤维板(MIP-MDF)是中国木制家具材料中主要使用的板材，其板材和家具产品中释放的甲醛对人体有害，受到广泛关注。本文旨在关注MIP-MDF及其家具产品的甲醛释放量。本研究利用1 m³的气候室测量MIP-MDF和MIP-MDF床头柜的甲醛释放量与时间和负荷因素的关系。结果表明，在2 ~ 24 h阶段，MIP-MDF材料床头柜甲醛释放量变化明显，整体趋势呈现先上升后下降的变化趋势。MIP-MDF的甲醛释放量在40 h后趋于稳定，而床头柜的甲醛释放量在60 h后趋于稳定。随着时间的推移，MIP-MDF和床头柜的甲醛释放量变化几乎相同。MIP-MDF和床头柜的甲醛释放量与承载量呈显著正相关。随着承载负荷的增加，甲醛释放量有增加的趋势，但随着承载负荷的增加，影响程度逐渐降低。

Formaldehyde emission pattern of melamine impregnated paper decorated medium density fiberboard and its furniture products

Melamine-impregnated paper decorated medium-density fiberboard (MIP-MDF) is the main board used for wooden furniture materials in China, and the formaldehyde released from the board and furniture products is harmful to human beings and is a wide concern. This paper aimed to pay attention to the formaldehyde emission of MIP-MDF and its furniture products. This study utilized a 1 m³climatic chamber to measure the formaldehyde emission of MIP-MDF and nightstand made of MIP-MDF in relation to the time and load factors. According to the results, in the 2 to 24 h stage, the emission of formaldehyde in the nightstand made of MIP-MDF materials changed significantly, and the overall trend showed a changing trend of first increasing and then declining. The formaldehyde emission of MIP-MDF stabilized after 40 h, while the formaldehyde emission of the nightstand stabilized after 60 h. As time passed, the formaldehyde emission changes of MIP-MDF and nightstand were almost the same. The formaldehyde emission of MIP-MDF and nightstand has a specific positive correlation with the carrying load. With increased carrying loads, the formaldehyde emission tends to increase, but the degree of influence gradually decreases with the addition of the carrying loads.
