概要 This investigation used Japanese cedar (Cryptomeria japonica D. Don.) as a material, one of the main plantations in Taiwan. After first having been through the pressure treatment process with a commer...cial fire retardant chemical (FR), the flame-retardent panels, for indoor use, were manufactured using the hot pressing method. The objective of this research was to increase the value-added dimension of the end product, thereby increasing the utilization of Taiwan's plantations. The hope was to enable Japanese cedar plantations in Taiwan to improve upon their economic efficiency by providing information to forestry industry workers, interior decorates, and finishing material suppliers, thereby increasing the profit indirectly for the forestry workers in change of their own forest. The results obtained showed that the flame retardancy of the panels was substantially increased after being pressure treated with FR and then hot pressed. In addition, the physical properties improved as well. The results of the micrographic and soft X-ray analysis showed that FR occured inside the cell cavity or lumen of the panels, and resulted in a higher surface density of the panels, reaching up to 1.80g/cm[3]. Based on the results of this study, hot pressing for 30min with 4MPa at 120℃ was able to quality for CNS 11668, and reach the second grade of CNS 7614 as well.続きを見る
