摘要:

针对超薄型地膜产品生产使用和耐候性差等原因造成使用后不降解或难以回收利用的问题,将农业生产使用后的废旧地膜采用机械或人工方式回收,经过清洗、改性等工艺过程制成颗粒。将回收料与小麦、玉米秸秆粉复合加工制备了复合板材,并对板材的力学性能进行了测试。结果表明,按照10 %~50 %(质量比,下同)的废旧地膜颗粒添加量制备的复合板材,符合相关性能要求,可应用于复合板材、窨井盖等。

Abstract:

The waste plastic films used in agricultural production was recycled mechanically or manually. These recycled films were further made into particles through cleaning, modification, and other technological processes. According to the proportion of 10 wt%~50 wt%, the recycled material were used in the manufacturing of pipes and woven bags (cloth), boards with straw, the production of manhole covers or the refining of gasoline and diesel.

Key words: waste plastic film, recycling, application, process technology
