摘要
总结了近年来国内外尼龙6物理和化学回收等方面的研究情况,首先介绍了废旧尼龙6的预处理流程,然后介绍了4种废旧尼龙6的回收技术,包括填埋处理、能量回收、物理回收及化学回收,着重介绍了化学回收中的水解、氨解、醇解和离子液体法及优缺点,并探讨了废旧尼龙6回收技术在工业中的实际应用.目前,化学回收技术所需反应条件较为苛刻,对反应设备的要求较高,未来温和、低能耗、绿色是化学回收技术发展的主要方向.
Abstract
The research on the physical and chemical recycling technology of nylon 6 at home and abroad in recent years was summarized.The pretreatment process of waste nylon 6 was introduced,followed by four recycling technologies for waste nylon 6,including landfill treatment,energy recovery,physical recycling,and chemical recycling.The advantages and disadvantages of hydrolysis,ammonolysis,alcoholysis and ionic liquid methods of chemical recycling technology were introduced,and the practical application of waste nylon 6 recycling technology in industry was discussed.At present,the reaction conditions required for chemi-cal recycling technology are relatively harsh,and the requirements for reaction equipment are higher.In the future,mild,low energy consumption and green are the main directions for the development of chemical recycling technology.
