NIR SPECTROSCOPIC MONITORING OF RESIN-LOADING DURING ASSEMBLY OF ENGINEERED WOOD PRODUCT |
摘要 |
Calibrating near infra red (NIR) spectroscopic instrumentation for quantitative measurement of resin-loading of prepared wood materials, as moving in an assembly-forming line, for subsequent pressing under heat and pressure for manufacture of engineered-composite wood product. Feedback of measured data of resin-loading, during in-line assembly operations, enables maintaining consistent resin-loading and optimizes resin usage. Calibration of NIR spectroscopic instrumentation can be carried out on equipment simulating in-line movement of pre-established reference-source test-samples; or, can be carried out during on-line movement of wood-material test samples. The developed calibration method removes absorptive effects at wavelengths for constituents other than resin, such as the moisture content of the wood-materials and of the resin, while maintaining accurate and prompt NIR spectroscopic measurements of resin-loading in a continuous assembly line. |
