Polyvinyl chloride overlaid veneered plywood (PVC-VP), melamine-impregnated paper overlaid veneered plywood (MI-VP) and unfinished plywood (UF-P) were used as the experimental materials to explore the emission characteristics of volatile organic compounds (VOCs) and different VOC components from plywood under different loading factors. A 15L small chamber and gas chromatography-mass spectrometer were used as equipment. Under the conditions of a temperature of 23.5 °C ± 1 °C, relative humidity of 50% ± 5%, gas exchange rate of 1 h⁻¹, and loading factors of 1m²m⁻³, 1.5m²m⁻³, 2m²m⁻³, 2.5m²m⁻³, VOCs were collected from plywood on days 1, 3, 7, 14, 21 and 28 for analysis. The results showed that the loading factors had a greater impact on VOCs released from veneered plywood in the early stage, but a smaller impact in the later stage. However, loading factors influenced the middle and late stages of VOCs release from UF-P. Aromatic hydrocarbons account for the largest proportion in VOC components in plywood, and their decreasing rate increased with the loading factors. Polyvinyl chloride (PVC) and melamine-impregnated paper contain olefins and esters, which were released rapidly before the balanced period. The relationship between VOCs released from plywood and loading factors was nonlinear and affected by the use of decorative materials. Therefore, the fitting curves of PVC-VP, MI-VP and UF-P had different functional relationships due to the different surface decorations.

聚氯乙烯覆膜胶合板（PVC-VP），三聚氰胺浸渍纸覆膜胶合板（MI-VP）和未加工胶合板（UF-P）被用作实验材料，以探索挥发性有机化合物（VOC）的排放特性。胶合板在不同的加载因子下会产生不同的VOC成分。使用15L小室和气相色谱-质谱仪作为设备。下23.5℃±1℃，相对的50湿度的温度的条件下％±5％，在1个小时的气体交换率^-1，和1M的负载系数²米^-3，1.5M ²米^-3， 2米²米^-3，2.5米²米^-3在第1、3、7、14、21和28天从胶合板上收集VOC进行分析。结果表明，加载因子在早期对贴面胶合板释放的挥发性有机化合物影响较大，而在后期则影响较小。但是，负载因素影响了UF-P释放VOC的中后期。芳烃在胶合板中VOC成分中所占比例最大，并且其降低速率随负载因子的增加而增加。聚氯乙烯（PVC）和三聚氰胺浸渍纸包含烯烃和酯，它们在平衡期之前迅速释放。胶合板释放的挥发性有机化合物与载荷因子之间的关系是非线性的，并受到装饰材料的使用的影响。因此，PVC-VP的拟合曲线
