| titleOfInvention | Separation and Recovery Method of Waste Polyester Magnetic Film |
| abstract | The present invention relates to a method for separating and recovering components of a waste polyester magnetic film, and more particularly, to a waste polyester magnetic film into a high-pressure reactor and to 20 to 300 parts by weight of alcohol and 0.01 to 10 parts by weight of a catalyst. After the conversion to nitrogen atmosphere, the high pressure reactor was sealed and the reaction temperature was raised to 120 to 300 ° C. while the reaction mixture was mixed. The present invention relates to a method of chemically decomposing polyester, polyurethane resin, and PVC of waste polyester magnetic film by transesterification and pyrolysis, and then separating and recovering them into pure raw materials through a multi-step separation operation process. Separation and recovery method of waste polyester magnetic film as described above Not only through substantial number of incineration to reuse treated waste polyester magnetic films that were very effectively, but also solve the problem of the imposition of the incineration process. |
