摘要
根据连续平压机同一框架内压力相等的实际生产情况,利用单层热压机模拟纤维板连续平压机的各框架的工作状态,通过正交试验法,研究了4种厚度(3、5、12mm和16mm)纤维板的最佳热压工艺,探究了最佳工艺条件下4种厚度板坯在成型过程中的性能变化。结果表明,3mm厚的纤维板最佳工艺参数为:热压温度210℃,热压压力0.8×P_2,钢带速度1000mm/s,;5mm厚的纤维板最佳工艺参数为:热压温度210℃,压力0.9×P_2,钢带速度800mm/s;12mm厚的的纤维板最佳工艺参数为:热压温度220℃,压力1.3×P_1,钢带速度350mm/s;16mm厚的的纤维板最佳工艺参数为:热压温度220℃,压力1.3×P_1。
Considering the each frame unit of continuous fiat press machine,in which the pressure is equal,as one hot-press stage in continuous pressing, the authors take advantage of single-opening press to simulate each frame unit and study the best hot pressing technology of 3mm, 5mm, 12mm and 16ram thickness fiberboard by orthogonal test. The results show that the hot pressing technology of 210℃,0.8 × P2 MPa and speed 1 000mm/s is best for 3mm fiberboard; the hot pressing technology of 210℃, 0.9 ×P2 MPa and speed 800mm/s is best for 5ram fiberboard; the hot pressing technology of 220℃,1.3 × PI MPa and speed 350mm/s is best for 12mm fiberboard; and the hot pressing technology of 220℃,1.3 × P1 MPa and speed 250mm/s is best for 16mm one.
