【摘要】 为了提高和改善杉木积成材的物理力学性能和外观质量,促进杉木积成材的推广应用,初步探索了杉木积成材浸渍纸贴面工艺的可行性。试验采用在杉木积成材与浸渍纸之间加入一张木单板,且一次性压贴在杉木积成材基材上的方法,并测试了贴面板的物理力学性能,分析了贴面工艺,选择了较佳工艺参数。结果表明:对杉木积成材进行浸渍纸贴面切实可行。较佳贴面工艺参数为:热压压力2 5MPa,热压时间4min,热压温度160℃。表3参11更多还原

【Abstract】 The feasibility of paper impregnated thermosetting resin overlaying technology of Chinese fir orient laminated strand lumber was studied to improve its physical and mechanical properties and surface quality, and promote its application and popularization. In the experiments, a veneer was added in paper impregnated thermosetting resins and Chinese fir orient laminated strand lumber and overlaying on its surface. The physical and mechanical properties of overlaying board were tested and its overlaying technology was analyzed for the optimum technology parameters. The results show that paper impregnated thermosetting resins overlaying technology of Chinese fir orient laminated strand lumber is practical; the optimum parameters are as follows: 2.5 MPa hot pressing pressure, 4-minute hot pressing and 160℃ hot pressing temperature.更多还原
