摘要
为有效回收废旧聚酰胺材料并制造再生锦纶,避免环境污染和资源浪费,通过文献查阅和实地调研,总结废旧锦纶6材料的回收并再生为锦纶6的方法,重点阐述再生锦纶原料的化学回收方法,着重分析化学法再生锦纶生产技术存在的问题以及未来的发展方向。研究表明:目前废旧锦纶6材料回收率低,再生锦纶原料来源不足,设备要求高且回收过程存在污染,而离子液体解聚技术凭借其节能环保的优势或将成为废旧锦纶6材料化学回收的发展方向。化学再生锦纶6或将成为未来聚酰胺废料处理的主要途径。
In order to effectively recycle polyamide waste materials and manufacture regenerated nylon to avoid environmental pollution and waste of resources, the method of recycling and regenerating nylon 6 waste materials into nylon 6 fiber was summarized through literature review and field research. The chemical recovery methods of recycled nylon raw materials were emphasized. The problems existing in the production technology of chemical regenerated nylon and its future development direction were analyzed. The study showed that the current recovery rate of nylon 6 waste material was low, and the source of recycled nylon raw materials was insufficient, equipment requirements was high, and there was still pollution in the recycling process. The ionic liquid depolymerization technology may become the development direction of chemical recycling of nylon 6 waste materials due to its advantages of energy saving and environmental protection. Chemical regenerated nylon 6 fiber may become the main way to treat polyamide waste in the future.
