铝厂提炼铝后所余下的废品红泥,既不能回收再用,又不能经济地当作其他工业原料,长期做废料堆放,既占地又污染环境,成为炼铝工业的一大难题。台湾工业技术研究院联合工业研究所多年来致力于废品红泥的分析与开发利用,曾利用红泥与不饱和聚酯树脂相结合,经钴60伽玛射线照射,制成人行道面砖,但因制造成本过高而难予推广应 The waste red mud left by the aluminum plant after refining aluminum can neither be recycled nor used economically as other industrial raw materials. It has long been used as waste dumping, which not only covers land but also pollutes the environment, and has become a major problem for the aluminum smelting industry. The Institute of Industrial Technology of the Institute of Industrial Technology of Taiwan has been devoting itself to the analysis and development of waste red mud for many years. It used red mud combined with unsaturated polyester resin to form a sidewalk tile by irradiation with cobalt 60 gamma rays. The manufacturing cost is too high and it is difficult to promote
