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。
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。
The cost of the adhesive was decreased, which was estimated at by 40% in comparing with that of PF-resin.
马尾松树皮混合胶的成本与纯酚醛胶相比,可降低40%左右。
