| Abstract | The study of influence artificial weathering on color changes of selected wood species from Africa The work deals with the change in color selected tropical wood species from Africa during artificial weathering: doussie (Afzelia sp.), iroko (Milicia excelsa (Welw.) C.C. Berg.) and opepe (Nauclea diderrichii (De Wild. & Th.Dur.) Merr.). The accelerated weathering method was used to determine the influence of ageing on color stability of wood. This methods consisted of alternating: soaking wood in water, drying at a temperature of 70 °C and UV radiation exposure The result of wood discoloration was evaluated using CIE Lch system to the value of the total color change ΔE. Changes of particular color parameters (lightness, chroma, hue) were also observed during exposure. The results showed that tested species of wood change their color similarly under the influence of the artificial weathering and the changes in the tested wood appearance occur in different scope. Afzelia sp. showed the greatest range of the total color change. The largest changes in intensity of the color of wood took place at the beginning of artificial weathering process. |
