摘要:
利用单因素试验方法,研究了热压温度、热压时间、热压压力和施胶量对使用改性大豆蛋白胶黏剂制造的杨木胶合板胶合强度的影响规律。结果表明:在100~220 ℃热压温度范围内,随着热压温度的增加,胶合强度显著增大; 在35~60 s/mm热压时间范围内,胶合强度随热压时间的增加呈上升趋势,当时间从60 s/mm升至85 s/mm,胶合强度几乎保持一致; 热压压力在1.25 MPa时,胶合强度达到最大值; 施胶量在130~430 g/m2 热压时间范围内,胶合强度随施胶量的增加呈上升趋势。由此得出最优工艺参数为:热压温度180 ℃,热压压力1.25 MPa,热压时间60 s/mm,施胶量为310 g/m2
Abstract:
Using a single factor method, we investigated the influence of hot pressing parameters(temperature, time and pressure)and resin content on bonding strength of plywood glued with modified soybean protein adhesive. The results indicated that the bonding strength increased significantly when hot pressing temperature rose from 100 to 220 ℃. It also increased with prolonged hot pressing time ranging from 35 to 60 s/mm. When hot pressing time increased from 60 to 85 s/mm, the bonding strength did not change significantly. The plywood exhibited the maximum bonding strength at a pressure of 1.25 MPa. The bonding strength increased when resin content rose from 130 to 430 g/m2. The optimum process was therefore suggested as follows: The plywood is pressed at 180 ℃ with a pressure of 1.25 MPa; the pressing time is 60 s/mm and the amount of adhesives is 310 g/m2.
