The impact of natural and artificial weathering on the visual, colour and structural changes of seven tropical woods
Original language description
This study investigates the effects of wood weathering on changes in its macroscopic and colour characteristics in connection with changes in its molecular and anatomical structure. Seven hardwoods suitable for outdoor architecture-bangkirai, cumaru, cumaru rosa, ip,, jatoba, kusia, and massaranduba-were exposed to the exterior out of ground contact for 1-36 months according to EN 927-3, and for 1-12 weeks in Xenotest with water spraying according to partly modified EN 927-6. With prolonged weathering, the following changes occurred in the top surfaces of all tropical woods: (1) visual-creation of longitudinal macro-cracks, (2) spectrophotometry and CIE-L . a . b -darkening in exterior exposure mainly due to pollutants, except for ip,, and vice versa lightening in Xenotest, as well as greening and blueing in both modes of exposure, (3) FTIR-faster decrease of guaiacyl than syringyl lignin, absolute decrease of conjugated and unconjugated carbonyl groups in the newly formed lignin-polysaccharide-extra
