Determining patterns in the formation of a polymer shell by powder paint on wood surface

An issue related to using wood and products for building structures is ensure their stability durability during operation within wide limits. Therefore, the object of this study was a change in properties polymer shell powder paint on thermal modification. It proved that process modification wood, its structure changes, accordingly, polymerization paint, degassing occurs, which affects shell. Namely, at temperature 180 °C untreated shallow bubbles craters are characteristic formed Instead, smooth surface marked sample thermally modified wood. Thermogravimetric analysis data show thermogravimetric curves characterized by loss mass original with increasing due processes dehydration, destruction hemicellulose lignin. This accompanied pyranose cycle, carbonization form carbon residue complex mixture volatile products. Due this, coating. Based obtained results adhesion treated epoxy polyester system functional additives °C, level 2.1 MPa. Reducing 130 increases 1.75 times, nature passes through For MPa, takes place increased fragility after
