中文摘要：
中密度纤维板生产中胶料的用量直接关系到产品的生产成本和产品质量及性能。将硫酸铜溶液加入到胶料中进行胶料标记可用来测控施胶量。使用X射线荧光光谱仪来定量分析作为中密度纤维板中胶料标记的CuSO4，建立标准工作曲线，并对样品进行分析精度、灵敏度、稳定性的试验。结果表明，Cu元素含量与分析线强度之间存在良好的线性关系，方法的效果良好。
英文摘要：
In the case of CuSO4 （based on resin solids） was premixed with the resin as a labeling agent, it＇s possible to quantify resin contents in medium density fiberboard （MDF）. The method is based on the principle that a specific metallic element shows its characteristic X-ray fluorescence spectrum, the intensity of which is correlated quantitatively to its concentration. Quantification of copper ion was performed using a wavelength dispersive X- ray fluorescence spectrometer （WDXRF）. Based on calibrations with laboratory prepared standard samples with known copper quantities, the results of XRF measurements were converted to resin loading rates. Linear calibration curves between fluorescence intensity and copper content were established. Test results show that the methods were simple, rapid, precise and reliable.
