Process for treating rigid PVC articles having a coating of soft PVC for recycling purposes |
摘要 |
<p>In this method of processing UPVC sections coated with plasticised PVC for re-use, the latter is converted to a free flowing form with the aid of a fluid. The fluid contains a plasticiser suitable for further plasticising the soft PVC coating, to remove it from the UPVC. The UPVC sections and detached material are both processed separately for re-use. Also claimed is a plant to carry out the method. The washing stage (4) contacts the UPVC sections intensively with fluid. Rinsing is followed by after-cleaning (5) spraying the UPVC parts with the fluid. There is an interception and separation stage (9,10) for the plasticiser/plasticised PVC mixture, and a following filter stage (11) passing a maximum particle size.</p> |
