Taking modified MF and PF resin as the adhesive and using "cool-hot-cool" technology, this paper designs two groups of technological parameters of hot-pressing to press bamboo curtain plywood.
以改性三聚氰胺甲醛树脂（MF树脂）和酚醛树脂（PF树脂）为胶粘剂，设计了两组热压工艺参数，按照“冷-热-冷”工艺压制竹帘胶合板。
We have adopted the method to place a hollow rigidity axle (with hole and ridge) in the bamboo curtain reel to proceed bound drying, which can improve drying velocity and drying quality effectively.
采用竹帘卷内放置有孔棱的空心刚性轴进行束缚干燥，可以有效提高干燥速度和干燥质量；
PF resin adhesive by mid-temperature curing is made on the main condition that the "cold-in and cold-out" technique used for bamboo curtain plywood should be changed into a "hot-in and hot-out" one.
将竹帘胶合板的“冷进冷出”工艺改造成“热进热出”工艺，关键技术是降低热压温度，而一种中温固化型的酚醛树脂是实现该技术的主要条件。
