乘用车塑料饰件回收过程高压水射流除涂层技术研究*

摘要

Based on a high-pressure water jet technology,the technology on coating removal for passenger car plastics recycling was developed.The theoretical analysis,numerical simulation and experimental study about the developed technology were carried out.The results show that high-pressure water jet technology can effectively remove the coatings on the surface of passenger car plastics.Moreover,high-pressure water jets equipment for automotive plastic coating removing is developed under the research and testing.There is no polluting emission and the water can be completely recycled in working process,which meet the requirements of clean production and sustainable development.%以高压水射流技术为基础，从理论、数值模拟及试验验证三方面开展了乘用车塑料饰件回收过程涂层去除技术研究，三方面的研究结果均证实了高压水射流技术可有效去除乘用车塑料饰件上的涂层。基于研究和试验的结果开发了汽车塑料饰件高压水射流除涂层专用设备，初步试用结果表明，采用该设备可有效去除汽车塑料饰件表面的涂层。此外，该设备工作过程中无污染排放，水可完全循环利用，满足清洁生产和节能减排的要求。
