This work evaluates the feasibility of incorporating electric arc furnace dust (EAFD), as filler in a polymer matrix, to obtain a moldable heavyweight sheet, useful for acoustic insulation in automotive industry. For this purpose EAFD from a steel factory that manufactures high quality steels, was characterized and different formulations of composites were prepared. Physical and mechanical properties, as well as fire behaviour were tested and compared with a polymer composite compounded with common mineral fillers. Optimum formulation with 25% EAFD fulfils the RoHs Directive used by automotive industry to regulate heavy metals content. Leaching test was also performed on prepared composites to classify the material after use.
本工作评估了将电弧炉粉尘（EAFD）作为填料纳入聚合物基质以获得可模压的重型片材的可行性，该片材可用于汽车工业中的隔音。为此，对来自生产高质量钢的钢铁厂的 EAFD 进行了表征，并制备了不同配方的复合材料。测试了物理和机械性能以及燃烧性能，并将其与用常见矿物填料复合的聚合物复合材料进行了比较。含有 25％EAFD 的最佳配方符合汽车行业用来控制重金属含量的 RoHs 指令。还对制备的复合材料进行了浸出试验，以对使用后的材料进行分类。
