摘　　要：对胶合板厚板作了缩短热压周期的试验，采用理论上较少采用的热压曲线与常规热压曲线进行对照，在２６２７张１５ｍｍ厚的胶合板试验中，由于采用新的热压曲线及缩短热压周期压制，试验结果表明，从板的物理力学性能及外观质量等均达到令人满意的结果．Temperature,pressure and pressing cycle are three important factors in plywood hot-press process,and they interact with each other. Hot-press cycle is a key factor affeacting product qualities under given temperature and pressure conditions. Shortening the hot-press cycle is of economic importance for plywood enterprises. Normal releasing pressure curve and broken-releasing pressure curve experiments were conducted for comparison in 15 mm thick plywood pressing. Physical and mechanical properties as well as appearances met the GB9846 1 9846 12-88 requirements.
