The objective of this project is to recycle wasted metal-plated plastics.The release of bonding between the coated metal and plastic substrate is accelerated by the aid of microwave and supersonic wave ( MSW ) in acid or basic solution . It takes very short time to debond coated metal with the aid of MSW , so that plastic substrate is only slightly altered . The recycled plastic substrate is modified by polymer blend compounding formulations and process to develop new polymer alloys or composites , which can be extruded to make sheets or injected to make computer outer covers . The technology to recycle the Al-plated lamp cover and Ni-plated injected part has been developed . 10 patents related to this technology have been finished and applied to the National Patent Office . The project team has also developed the technique to recycle the polymer film-coated plastic glasses . 8 patents have been accomplished to debond the polymer film from transparent plastic glass . Besides , 2 more patents enhance the homogeneous mixing of additives in plastics during polymer blending. This technology provides a good opportunity to separate the plated metal or coated film from plastic substrates . The recycled substrates are then blended to deueloped polymer alloys／composites . This project deserves intensive research and development with high renewability . The technology outputs generated by this project have been transferred to four companies and used in mass-production processes. It’s obvious that the patents and technologies of this project are of great commercial values.
