废旧风电叶片在工程塑料领域的应用实验OA
Application of waste fan blades in engineering plastics field:experimental study
随着玻璃钢制品市场的不断扩大,其产量逐年上升,与此同时其废弃物数量也与日增,未来废弃玻璃钢的数量将会呈爆发趋势增长.为了开发废旧玻璃钢资源化利用新途径,对破碎的废旧风电叶片粉末开展研究,首先,对废旧风电叶片粉末的形貌及结构进行测试;然后,使用液体偶联剂KH-550 和液体石蜡对废旧风电叶片粉末进行改性,并与聚乙烯(PE)进行混合;最后,对得到的材料进行力学性能分析.结果显示,改性后的复合材料与常规配方的材料相比,纵向回缩率降幅达49.85%,同时拉伸强度、断裂伸长率和简支梁冲击强度分别提升66.11%、21.58%、42.72%.
With the expansion of glass fiber-reinforced plastic(FRP)products market,its output increases year by year.At the same time,the amount of its waste also increases dramatically.The number of waste FRP will increase explosively in the next few years.To develop a new way for recycling waste FRP,the broken waste fan blade powder is investigated.Firstly,the morphology and structure of the waste fan blade powder are tested.Secondly,the waste fan blade powder is modified by liquid coupling agent KH-550 and liquid paraffin,and then mixed with polyethylene(PE).Finally,the mechanical properties of the obtained material are analyzed.The experimental results show that,the longitudinal shrinkage rate of the modified composite reduced by 49.85％compared with that of the conventional formula,and the tensile strength,elongation at break and simply supported beam impact strength increased by 66.11％,21.58％and 42.72％,respectively.
