| 摘要:文章综述了国内外铝塑分离技术的研究进展,分析和比较了溶剂法、高压静电分离、氩气电解等技术的基本原理和工艺过程等特点；指出铝塑高效分离再利用存在的问题及铝塑分离技术的未来研究方向。 |
| Abstract:The amount of waste aluminum-plastic composite packaging, which contains a large number of high quality fibers and aluminum-plastic materials increases year by year. In the present paper, separation technologies of aluminum-plastic composites in the world were reviewed. The principle and processes of various separation approaches, such as separation with solvent, electrical separation and Argon electrolysis were analyzed and compared. Finally the existing problem of efficient separation and recycling as well as future research directions of aluminum-plastic composite were discussed. |
