Abstract

This research aims to optimize densified laminated veneer lumber production parameters of compression ratio, press temperature, press time, and adhesive spread rate to maximize their mechanical properties. In the manufacturing process of densified laminated veneer lumber, I-77/51 American poplar clone (Populus deltoides) veneers and urea formaldehyde adhesive are used. The results showed that the compression rate and press time had the most significant impact on the mechanical properties of densified laminated veneer lumber. The optimal production conditions were determined as follows: 38 % compression, press temperature of 170 °C, press time of (10±3) minutes, and spread rate of 150 g/m2. Modulus of rupture, modulus of elasticity, tensile shear strength, and tensile strength perpendicular to panels surface of densified laminated veneer lumbers produced under these conditions increased by 49 %, 8 %, 71 %, and 23 %, respectively, compared to the control group of laminated veneer lumber. So, it can be said that the production parameters of densified laminated veneer lumbers can be optimized safely and effectively using Taguchi method-based grey relational analysis.

优化使用脲醛树脂生产的层压单板的生产参数

本研究旨在优化压缩比、压制温度、压制时间、胶粘剂涂布率等致密单板复合材的生产参数，使其力学性能最大化。在致密层压单板木材的制造过程中，使用I-77/51美国杨树无性系(Populus deltoides)单板和脲醛胶粘剂。结果表明，压缩率和压缩时间对密实单板的力学性能影响最为显著。确定了最佳生产条件:压缩率为38%，压制温度为170℃，压制时间为10±3分钟，散布率为150 g/m2。在这些条件下生产的致密单板的断裂模量、弹性模量、抗拉剪切强度和垂直于面板表面的抗拉强度分别比对照组的单板增加了49%、8%、71%和23%。因此，利用基于田口方法的灰色关联分析可以安全有效地优化密实单板木材的生产参数。
