摘　　要：为了优化涂胶工艺、降低成本、提高生产实践中胶黏剂的利用率,通过对不同调胶工艺进行正交试验,对施胶效果进行施胶量的单因素试验,并利用胶黏剂扫描系统对单板施胶效果进行量化分析。结果表明:单板含水率越低,胶黏剂覆盖率越高;单板表面胶黏剂覆盖率随施胶量的增加而增加,胶滴尺寸基本恒定;加面粉后提高了胶黏剂在单板上的表面覆盖率;紧面涂胶胶黏剂覆盖率比松面高,松紧两面胶滴尺寸变化不明显;单板松紧两面施胶效果差异较小。In order to optimize the adhesive application techniques,reduce cost and improve the utilization of adhesive,we compared different mixing processes of adhesive through an orthogonal experiment and different adhesive consumption on adhesive efficiency using single-factor tests.By using GluScan,we further quantified the effect of veneer adhesive efficiency.The results showed that the adhesive coverage was higher with the lower moisture content and higher adhesive consumption.The adhesive coverage increased with the increase of adhesive consumption,and drop size retained constant.An addition of flour improved the adhesive surface coverage of veneer.The adhesive coverage on the tight side was higher than that on the loose side,and drop size on both sides did not change significantly.The variation of the adhesive consumption on both sides of the veneer is small.
