A INTELLIGENT CLASSIFICATION METHOD FOR PREPROCESSING BASED OF A BLACK PLASTIC SORTING BY RAMAN SPECTROSCOPY

摘要

The present invention relates to a pretreatment-based intelligent classification method for selecting black plastics by Raman spectroscopy. The pretreatment-based intelligent classification method comprises the steps of: obtaining spectrum data for each black plastic material (PET, PP, PS); pre-processing the spectrum data for each black plastic material; learning the chemical properties of each black plastic material; and classifying black plastics on the basis of the chemical properties for each material. It is possible to automatically classify the black plastics according to the chemical properties of each material such as PET, PP, and PS.
