退役汽车塑料材料NIRS识别技术及设备研究

Research on Near-infrared Spectrum Identification Technology for Plastic Materials of End-of-life Vehicles

基于近红外塑料识别技术具有操作简单、稳定性好、效率高、环保清洁、成本低等特点,开发了一套退役车用塑料近红外识别试验系统。该系统的硬件部分包括BTC261E阵列型近红外光谱仪、BIP2.0积分球、光纤探头、钨丝灯光源、测试台架等,软件部分包括样品采集单元、模型建立和校正单元、样品检测单元。系统的应用测试结果表明,车用塑料的识别准确率超过95%,满足车用塑料识别的要求,为进一步工业化开发和应用做好了铺垫,同时为开展退役汽车塑料的回收利用奠定了坚实的基础。

A near-infrared spectrum（NIRS） identification test system for plastic materials of end-of-life vehicle was developed based on NIRS identification technology for plastic materials which had some characteristics such as simple operation, good stability, high efficiency, no pollution, and low cost and so on. The hardwares of the system consist of NIRS spectrometer, integrating sphere, tungsten light source, fiber optic reflection probe, the test bench, etc. The software system is composed of the sample acquisition module, model building and calibration module, sample test module. The results show that the system recognizable rate is over 95%, which meet the requirements of the identification of automotive plastic and lays a good foundation for further development and application.
