| Abstract: | The content of resin in PVC edge banding is the key factor that determines its mechanical strength, flexibility and service life. In this paper, the dissolution-precipitation method is adopted to extract the resin from the PVC edge banding, and the content of resin is determined combined with the identification using infrared spectroscopy. The operation is simple and fast, and the results are accurate and reliable without using large-scale equipment. |
