Povrchové úprava dřevěného obložení dřevostavby
Šindler, Miroslav
This diploma thesis shall address the surface treatment of wood paneling of log homes. Samples representing wooden paneling were painted and exposed at two different locations in different climate conditions. The first set of samples was exposed on the premises of the Mendel University in Brno and the other one in Berkhamsted in UK. The placement of individual samples sample took place on the premises of the university where we were provided with iron racks on which samples remained for two years. Over the years, the above-mentioned measurement was performed on the roughness, lightfastness and gloss of coating material using respective devices. Samples, which were exposed in the UK, were inserted into the pre-formed racks made of oak wood and they were measured at the start of their exposure and after the completion of the experiment. That experiment shall show the changes of aesthetic and physical and mechanical properties which can be observed in individual plank lining. In our work we deal primarily with the change of the color and roughness of thematerial. As we know that wood exposed to external weather conditions is stressed by various factors, biotic as well as abiotic factors, the structure and appearance under these conditions are changing over time. These changes are also affected by the exposure of a product or the place where the test set of samples is exposed. Consequently, we will discuss the changes in color and surface roughness before and after the exposure.
