influence of artificial weathering on acetylated beech solid wood and particleboard by spectroscopy and electron microscopy
this research was conducted to investigate the effect of acetylation on weathering resistance of solid wood and particleboard produced from acetylated particles of fagus orientalis. after 12 hours soaking in acetic unhydride, in order to achieve three levels of weight gain, 5, 9 and 16%, acetylated particles of bech wood were heated in oven at 120oc for 30, 90 and 240 minutes, respectively. als...
متن کاملComparative Study of Wood Flour Photodegradation of Two Wood Species Submitted to Artificial Weathering
In this work Eucalyptus grandis and Dipteryx odorata were submitted to photodegradation by ultraviolet radiation. The effect of ultraviolet radiation irradiation on the color change and chemical composition of each wood flour were evaluated. The samples were submitted to a total of 500h of artificial weathering using condensation stages and ultraviolet radiation B irradiation cycles. The change...
متن کاملWood formation in Abies balsamea seedlings subjected to artificial defoliation.
We determined the cambial sensitivity and quantified the anatomical differences in xylem of Abies balsamea (L.) Mill. seedlings subjected to artificial defoliation to simulate spruce budworm feeding. Defoliation was performed by removing two-thirds of needles of all current-year shoots for up to four consecutive growth cycles to account for inter- and intra-annual xylem formation. In Experiment...
متن کاملCoating Acetylated Wood
Wood exposed to the outdoor environment is susceptible to weathering due to a series of chemical, biological and physical processes. Acetylation of wood is known to reduce cell wall moisture content, improve dimensional stability and durability against fungal decay. As a result of these improvements, less stress is created between the coating and the wood surface improving the performance of th...
متن کاملVisual Simulation of Wood Weathering
The aging process of material is an unavoidable natural phenomenon. Thus, several CG techniques for representing aging phenomena, such as metal corrosion and stone weathering, have been studied. In this paper, we propose a visual simulation method of wood weathering. First, we present the wood model in consideration of branching. Then, we give the algorithm for representing the weathering of th...
