| Outline of Final Research Achievements |
Various kinds of sheets made of PVC are used as a finishing material for buildings. These used PVC sheets are dumped volumiously as mixure waste.Therefore, we aim to develop a recycling technique for PVC building wastes.Here we report a new technique that can separate PVC recycled powders from PVC building wastes. Specifically, it targeted tile carpets, wallpapers and PVC waterproof sheet. Moreover, here we produced new recycling sheets by PVC recycled powder, and evaluated the quality of the recycled sheets. For instance, here we studied the influence for the tensile property and the durability of the recycled sheet by a waste kind and mixture rate. These observations indicate that the new recycling technique is able to reduce PVC building wastes and we intend for practical use.
