竹席/竹碎料新型建筑模板制备工艺研究

Study on preparation technology of bamboo mat/bamboo particle board for new construction formwork

将小径竹及竹材加工剩余物加工成一定规格的竹碎料。以竹碎料为芯层,以竹席为表层组成板坯,通过热压制备竹席/竹碎料新型建筑模板。采用正交试验,选取热压时间、热压温度和施胶量作为工艺因素,对竹席/竹碎料复合新型建筑模板制备工艺进行了研究。研究发现,施胶量对产品的各项性能指标的影响最显著,其次是热压时间和热压温度。通过分析得出优化工艺:热压时间70 s.mm-1,热压温度为170℃,施胶量为10%。

Small diameter bamboo and bamboo processing residues were cut into particles.Bamboo particles（as the core layer） and bamboo mats（as the surface layer） were fabricated into slab,which was hot-pressed to form a bamboo mat/bamboo particle new construction formwork.Adopting the orthogonal test,taking hot-pressing time,hot-pressing temperature and glue consumption as the process variables to research preparation technology of bamboo mat/bamboo particle new construction formwork.The results show that glue consumption has the largest effect on every quality index of the product,hot-pressing time and hot-pressing temperature have less effect.Finally,through analysis optimization technology was obtained： hot-pressing time is 70 s/mm,hot-pressing temperature is 170 ℃,and glue consumption is 10%.
