释放面积对三聚氰胺浸渍胶膜纸饰面中密度纤维板家具甲醛释放量的影响

Effect of Paper Impregnated Resin Overlaying Exposure Area on Formaldehyde Emission of Melamine Medium Density Fiberboard

随着生活水平的提高,人们对室内甲醛污染关注度越来越高,三聚氰胺浸渍胶膜纸饰面中密度纤维板作为最常用的家具材料之一,在室内空间的过量使用会造成甲醛污染。为了研究不同释放表面积对三聚氰胺浸渍胶膜纸饰面中密度纤维板家具甲醛释放量的影响,为其在室内使用提供参考,利用1 m^(3)气候箱,根据GB/T 17657—2013标准测定三聚氰胺浸渍胶膜纸饰面中密度纤维板及其家具的甲醛释放规律,并根据不同释放面积建立单位面积甲醛释放量的关系,进行线性拟合,研究发现单板及家具的甲醛释放量均呈现先上升后下降最后趋于稳定的变化趋势,且单位面积甲醛释放量与释放表面积的关系为y=0.0036 x^(2)-0.0204 x+0.0541,R^(2)=0.9287。该公式在一定程度反映了甲醛释放量受释放面积的影响,对家具在实际使用中的使用具有一定参考价值。

With the improvement of living standards,people are paying more and more attention to indoor formaldehyde pollution.Melamine medium density fiberboard,as one of the most commonly used furniture materials,can cause formaldehyde pollution in indoor spaces when excessively used.In order to study the effect of different release surface areas on the formaldehyde emission of melamine medium density fiberboard furniture and provide reference for its indoor use,this paper used a 1 m^(3) climate chamber to determine the formaldehyde emission characteristics of melamine medium density fiberboard and its furniture according to the GB T17657-2013 standard.The relationship between the unit area formaldehyde emission and different release areas was established through linear fitting.It was found that the form‐aldehyde emissions of veneer and furniture showed a trend of initially increasing,then decreasing,and finally stabilizing.The relationship between unit area formaldehyde emission and release surface area was y=0.0036 x^(2)-0.0204 x+0.0541,R^(2)=0.9287.The formula to some extent reflects the influence of release area on formaldehyde emission,and has certain reference value for the practical use of furniture.
