Slabejová, Gabriela, 1975- Vplyv vybraných faktorov na zmenu farby transparentných povrchových úprav bukového dreva = Influence of selected factors on colour change of the transparent finishes at beech wood / Gabriela Slabejová, Jozef Fekiač, Miloš Pánek. -- Obr., tab. -- This article is focused on the influence of coating thickness on colour changes of beech surface with transparent coating. The influence of following factors has been also observed: treatment of wood surfaces before coatings application, and the type of coating. The influence of thickness of the coating on the colour changes during artificial weathering in the Xenotest Q-SUN was also researched on selected specimens. The colour of the surface (the values L*a*b*) was measured by spectrum photometer BYK-Gardner GmbH in CIELAB system. The colour change ΔE* was evaluated. Two different transparent coatings were applied on specimens at three various thicknesses. In the next step, the colour changes were observed after artificial weathering. The specimens with coatings were compared with references without coatings. The evaluation of the experiments has shown that technology of the surface treatment, type of the coating, and also its thickness much influenced the colour changes of beech wood treated with coatings. The influence of the thickness of the coating has been shown also by photo-stability measurements during artificial weathering; as the paint thickness was increased the colour changes also slightly increased. - Cieľom tejto práce bolo sledovať vplyv hrúbky náterového filmu na zmenu farby transparentných povrchových úprav bukového dreva, pri pôsobení ďalších sledovaných faktorov, ako je spôsob mechanického opracovania povrchu dreva a druh náterovej látky. Následne sa hodnotila zmena farby po pôsobení xenónového svetla v Q-SUN teste na dvoch povrchových úpravách (ekologickej – vodou riediteľnej a dvojzložkovej polyuretánovej s UV filtrom) s tromi hrúbkami náterového filmu a na povrchoch bez náterového filmu.
