原竹结构复合板木质门生产工艺初探

Study on the Producing Technology of the Original Structure Bamboo Composite Board Wooden Door

本试验是以直径为2－6cm的小径竹硬头黄竹为原料，通过木质门结构设计，按照原竹结构复合板生产原理，探索原竹结构复合板木质门的生产工艺流程，为原竹结构复合板在木质门的生产应用提供理论基础。结果表明：原竹结构复合板木质门的生产采用竹段交错组坯，聚醋酸乙烯酯为胶黏剂，以冷压方法压制。其中，压力为0．5MPa，时间为12h，温度为室内常温，涂胶量为190g／m2。经检测，木质门具有较好的质量，但木质门厚度偏差较大，与竹段弯曲度和施胶量不均匀有关。

The paper has explored the production process of the original bamboo structure composite board wooden door made of Bambusa rigida Keng with diameter of 2-6 cm based on its production principle through the structural design of the wooden door, which contributes to the production and application of wooden doors theoretically. The results showed that the adoption of bamboo segments in staggered arrangement, polyvinyt acetate as adhesive, and the cold pressing method are involved in the production of the composite board wooden door with original bamboo structure, in which the selected pressure, required time and glue-spread are 0.5 MPa, 12 hours and 190 g/m2, respectively. It can be concluded after the test that the door holds merit in quality, but meanwhile sharing the drawback of significant thickness deviation, resulting from the curvature of bamboo segment curvature as well as the uneven glue-spread.
