Povrchová úprava nábytku do chráneného exteriéru a jej priepustnosť voči vode
Machunková, Andrea
The diploma thesis deals with the influence of of water absorption, together with accelerated ageing on the specific properties of the surface treatment of black locust (Robinia pseudoacacia) and spruce (Picea sp.) wood intended for furniture in a covered exterior. And also was monitored the influence of the repeated sorption on the physical-mechanical properties of the surface treatments. The samples were made of solid wood and finished by transparent polyurethane and lasuring coating, which is intended for surface treatment of wood intended for exterior conditions. In the laboratory the coatings were tested for water permeability according to ČSN EN 927-5 and at the same time the samples were tested in model accelerated ageing in Xenoteste according to ČSN EN 927-6. The samples were examined by standardized tests for determine the properties of surface treatments in terms of changes in surface morphology.

This bachelor thesis deals with the influence of artificial UV radiation on plywood samples made of chosen woods - oak (Quercus), alder (Almus) and ash (Fraxinus) and examines the influence of surface conditioning on light permanency of wood surface. Samples were stained by water-soluble and solvent stains and finished by water-soluble and solvent lacquers. Samples were examined by standardized tests in the laboratory. We have determined the influence of type of stains on the speed of drying times and hardness and roughness of the coatings and evaluated changes in color depending on the surface conditioning.
