竹胶托板是我国混凝土砌块(砖)行业中小型生产线上主要托板类型,它设计使用寿命仅3~5年,如何实现废旧竹胶托板资源化再生利用是一项重要研究课题。本研究将废旧竹胶托板加工成再生竹屑和再生竹条,通过与竹席、竹帘、增强网片等组坯,以热固型酚醛树脂为胶粘剂,通过热压固化制备再生竹胶托板。研究表明,废旧竹胶托板在再生竹胶托板中的体积利用率达到50%~70%,所制再生竹胶托板具有质轻、密实、吸水厚度膨胀率低、胶合强度高等特点。
Bamboo pallets are the main pallets of small and medium-sized production lines in China’s concrete block (brick) industry. Their design life is only 3 to 5 years. How to realize the recycling and reuse of waste bamboo pallets is an important research topic. In this study, waste bamboo bamboo pallets processed into recycled bamboo scraps and recycled bamboo, and through the bamboo mat, bamboo curtain, reinforcing mesh and other group of blank, with thermosetting phenolic resin as adhesive, Pallet. The research shows that the volume utilization ratio of waste bamboo plastic pallets in recycled bamboo plastic pallets reaches 50% ~ 70%. The recycled bamboo plastic pallets have the characteristics of light weight, denseness, low swelling rate of water absorption and high bonding strength.
