AI Technical Summary
Technical Problem
The prior art is difficult to achieve uniform distribution and quantitative measurement of powdered adhesives in the wood particle mixture, resulting in unnecessary raw material consumption and cost increase in production.
Method used
The NIR spectrum of the mixture of powdered binder and wood particles was compared with the reference sample to determine the quantitative share of the binder by recording the NIR spectrum of the powdered binder and wood particles.
Benefits of technology
The continuous and non-destructive determination of the amount of powdered adhesive in production is achieved, which improves the accuracy and efficiency of the production process, and reduces raw material consumption and cost.

Abstract
The invention relates to a method for determining the amount of at least one biodegradable powdery binder in a mixture with wood particles / wherein the at least one powdery binder is present in a mixture with wood particles, the method comprises the following steps: providing a mixture of at least one powdered binder and wood particles as a reference sample, wherein the at least one powdered binder and wood particles in the mixture are present in a respective quantitatively defined mixing ratio; recording at least one NIR spectrum of the reference sample in a wavelength range between 900 nm and 1700 nm with at least one NIR measuring head; providing a mixture of at least one powdered binder and wood particles to be measured; recording at least one NIR spectrum of a mixture of at least one powdered binder and wood particles in a wavelength range between 900 nm and 1700 nm by means of at least one NIR measuring head; and determining the quantitative portion of the powdered binder in the mixture of the powdered binder and the wood particles by comparing with the NIR spectrum recorded for the reference sample.
