The main idea of this research is to explore the prospective of ashes accumulated during the energy production to be used as a filler for thermoplastics. The return of waste for processing into secondary raw materials is cost reducing and nature protective. In this study, low-density polyethylene filled with CaCO₃, burnt coal, and oil shale ash were produced and scrutinized. The optimal extrusion compounding and injection molding parameters are discussed. The effect of different filler load up to 30 wt% on the mechanical properties, structure, and morphology is investigated. It was found that the processing conditions for ash-filled compounds are similar to CaCO₃ filled. Mechanical properties such as tensile and impact strength of ash-filled composites are also close to CaCo₃ filled.

填充低密度聚丙烯的物理力学性能和形态：碳酸钙与油页岩和煤灰的比较研究

这项研究的主要思想是探索能源生产过程中积累的灰烬用作热塑性塑料填料的前景。将废物返回用于加工成二次原材料可以降低成本和保护自然。_{在这项研究中，生产并检查了填充有 CaCO 3}、燃煤和油页岩灰的低密度聚乙烯。讨论了最佳的挤出复合和注塑参数。研究了高达 30 wt% 的不同填料负载对机械性能、结构和形态的影响。发现填充灰的化合物的加工条件与填充的 CaCO ₃相似。灰填充复合材料的拉伸和冲击强度等力学性能也接近CaCo₃满。
