Comparing Durability of Wood Material in Natural and Artificial Weathering Conditions

Abstract

The performance of pre-treated and non-treated wood material samples (Fagus orientalis L. and Pinus sylvestris L.) subjected to outdoor conditions were examined in this study. A thermal treatment method, impregnation with MCQ and acrylic resin containing UV absorbers were used for wood protection and coating in the preservation process. The colour change parameters and the decrease rates of the compression strength were determined for the samples exposed in the outdoor tests. The natural weathering test applied to wood samples in the Sürmene coastal in the province Trabzon in Turkey was simulated artificially in QUV test cabinet. As a result the 50-60% similarity rate between the surface degradation of wood samples exposed to natural weathering and QUV test cabinet was determined by the statistical analysis.
