摘　　要：在阐明人造板甲醛含量/释放量测定原理的基础上,系统总结以往研究成果,通过对板材甲醛释放过程的分析,从理论上推导板材甲醛含量与空气中甲醛浓度的函数关系。根据标准测试参数及板材甲醛释放规律,对该函数关系进行适当简化,得到气候箱法甲醛检测值与穿孔萃取法、干燥器法甲醛检测值的线性计算方程,为建立人造板甲醛检测方法之间的相关性提供理论支撑,亦为线性计算方程的推广应用提供理论依据。Based on the principles of evaluation of formaldehyde content and release amount from wood-based panels,this paper systematically summarizes the previous researches on the correlation of formaldehyde detection methods on wood-based panels.Through the analysis of the formaldehyde release process from the wood-based panels,the functional relationship between the formaldehyde content of the panel and the formaldehyde concentration in the air environment was theoretically derived.According to the standard test parameters and the formaldehyde emission law of the panel,the function relationship is simplified,and the linear calculation equation was obtained from the climate chamber method,the perforation extraction method and the desiccator method,which provides theoretical support for establishing the correlation of formaldehyde detection methods for wood-based boards,and theoretical basis for the development and application of linear calculation equations.
