Sažetak
Blending is an important stage of wood-based composite production process, namely a relative small amount of adhesive is applied on a relatively large surface, especially if particles and fibres are in question. To visualize the presence of colourless adhesive appropriate dying technique should be used. The purpose of this paper is to present the possibility to determine the presence of adhesive by using FT-IR spectroscopy and to determine the surface covered with adhesive, by using dying technique and image analysis, when blending fines from different wood species. It was determined that we can determine differences between FT-IR spectra of blended and unblended particles. With image analysis we determined that surface covered with adhesive at fine particles averages between 23 and 27 %, and that adhesive is non uniformly distributed within and between particles.
