Abstract:
In this research, the effect of ammonia chemical vapors on the quality of surface wood species of common species in the furniture industry was evaluated. For this purpose, species of Platanus oriantalis, Fagus orientalis, Quercus castaneifolia, Betula pendula, betulus carpinus, Populus nigra, Morus alba l, Abies alba, and Cupressus arizonica were cut accordance to 5-927 EN standard (15 × 10 × 2 mm) and all samples were then transferred to conditioning room (EMC 12%) for 2 weeks. Then, all samples were stored in the test chamber for 30 days, and then the amount of color changes and roughness were evaluated after 5, 8, 15 and 30 days. The results of colorimetric studies showed that the highest and the lowest color variations were related to Quercus castaneifolia and Populus nigra species, which can be considered as one of the most effective factors in extracting materials. By increasing the storage time of wooden samples in ammonia vapor, color changes increased, but the highest color variation was observed in the first 15 days. Also, after ammonia Fuming, roughness was reduced in samples, with the greatest reduction in roughness observed in species of Quercus castaneifolia, Morus alba l and Platanus oriantalis currant.
