Standard principles: General plastics polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA) and polyethylene terephthalate (PET), the chemical composition and structure of each plastic are obviously different, and the infrared absorption spectrum has corresponding characteristic peaks. Using the characteristic peaks on the infrared absorption spectrum, we can effectively determine whether the unknown plastic contains the target component.
