Physical Recycling and Comprehensive Utilization Technology of Abandoned Printed Circuit Boards
Circuit boards are the foundation of electronic device industry. With the high speed development of information industry, the production of circuit boards is in rapid growing trend and the quantity of waste circuit boards also increases greatly. There is high recycling value for the abandoned printed circuit boards, but the original methods of recycling treatment such as burning, water washing and acid immersing caused serious pollution to the environment. Hunan Vary Sci-Tech Co., Ltd., in combination with the strength of scientific research institutes and utilizing the principle of “cyclone vortex separation, has developed “the complete physical recycling equipment for waste & old circuit boards. The separation of metal and nonmetal is effectively realized, and the nonmetal powder is further used in materialization. This text introduces the main principle, technological processes and advantages of the technology and the process of its development and industrialization application.
