Separation device for resin and glass fiber in non-metallic powder of waste circuit board

technical field

The invention relates to the technical field of industrial waste treatment and recycling in the technical field of environmental protection. Specifically, it relates to a sorting device for resin and glass fiber in non-metal powder of waste circuit boards, which realizes recycling and reuse of non-metal powder of waste circuit boards.

Background technique

As an indispensable and important part of various electronic products, printed circuit boards are widely used in household appliances, electronic entertainment equipment, computers and other electronic products. As a large-scale and high-capacity industry in the electronic component industry, the average annual growth rate of my country's printed circuit board industry has reached 14.4% in recent years, and its output has ranked first in the world. According to statistics, more than 500,000 tons of waste printed circuit boards (WPCBs) need to be recycled in China every year. Today, seeking a quick and environmentally friendly method to deal with a huge amount of WPCBs is a common problem and research direction faced by China, the United States and other major countries in the electronic information industry. At present, the resource utilization of waste printed circuit boards (WPCBs) is mainly the recycling of metal parts. As for non-metallic materials that account for more than 60% of the overall mass, but have lower economic benefits and are more difficult to handle, there are relatively few resources and safe disposal.

At present, the method of crushing is mostly used to separate metal and non-metal materials in printed circuit boards, mainly to recycle the metals, while the substrate material particles of waste printed circuit boards are thrown away as garbage. Due to the substrate material of the printed circuit board (PCB), it is difficult to melt and dissolve as a thermosetting composite material (SMC). method to deal with. Landfilling is currently the main method for large-scale disposal of waste printed circuit board substrates, but discarding the substrates as garbage will cause a lot of waste of resources and environmental pollution. Literature "Pyrolysis of printed circuit board waste and its product analysis)) (Sun Lushi, Lu Jidong, etc., "Journal of Fuel Chemistry" 2002 No. 3) and literature "Pyrolysis Experimental Research of Printed Circuit Board Substrate" (Peng Ke etc., "Environmental Pollution Control Technology and Equipment", No. 5, 2004) introduced the use of pyrolysis to treat waste printed circuit boards. This method is mainly to crack the polymer material in the printed circuit board into small molecular alkanes, which can be used as fuel and chemical raw materials after reasonable recovery; at the same time, most of the inorganic substances such as glass fiber in the printed circuit board do not change, and are still used as solid waste form exists. Since the printed circuit board contains a small amount of polymeric organic materials, and a lot of harmful gases are produced during the pyrolysis process (such as polybrominated diphenyl ethers can generate polybrominated dibenzodioxanes and polybrominated dibenzodioxanes) furan). Therefore, this method has problems such as high cost, complex process, and secondary environmental pollution, and is not the most ideal method for processing the substrate material of waste printed circuit boards.

Chinese invention patent "Manufacturing method of waste printed circuit board substrate material particles recycled board" (Xu Zhenming et al., patent number 200510023786.X), Chinese invention patent "Using waste circuit board non-metallic powder to prepare modified asphalt method" (Xu Zhenming et al. Zhenming et al., 200810042789.1) and Chinese invention patent "Using waste printed circuit boards to prepare wood-plastic composite materials" (Xu Zhenming et al., 200910054313.4) select non-metallic particles with a certain particle size through multi-stage crushing and high-voltage electrostatic separation, and A variety of additives are mixed and molded to produce a variety of recycled materials such as recycled boards, phenolic molding compounds and wood-plastic composites. Glass fiber in non-metallic powder can improve the mechanical properties of the material, but when the content is too much, it will hinder the fluidity of various raw materials such as polyethylene, thereby reducing the interface adhesion and resulting in a decline in mechanical properties. This places a requirement on controlling the content of glass fibers in the mixture. Being able to separate the glass fiber and resin in the mixture can greatly improve its performance for making recycled boards. At the same time, if the glass fiber and resin powder in the non-metallic powder are effectively separated, the comprehensive recycling value of the non-metallic powder can be greatly improved.
