Pilot scale PCB recycling system request
With the popularity of electronic equipment and the acceleration of replacement, discarded printed circuit boards have become a serious environmental pollution problem. In order to solve this problem, SUNY GROUP's PCB recycling system came into being. This article will introduce the relevant technical processes of this system in order to effectively recycle and process discarded PCBs and reduce the negative impact on the environment.
Collection and classification of waste PCBs
The Pilot scale PCB recycling system first needs to establish an efficient waste PCB collection system. The system should include waste PCB collection points, classification equipment, and transportation tools. Waste PCBs should be classified according to different types, such as single-sided boards, double-sided boards, and multi-layer boards, for subsequent processing.
PCB disassembly and cleaning
In the recycling system, PCB disassembly is a key link. First, the components on the PCB, including chips, capacitors, resistors, etc., are disassembled through a fully automatic circuit board disassembly machine. Next, the removed components need to be cleaned to remove dust and contaminants from the surface. Cleaning can use physical methods (such as water washing) or chemical methods (such as solvent cleaning).
Physical handling of PCB
The next step in the recycling system is the physical processing of the PCB. This step is designed to separate the various components of the PCB, such as the substrate, wires, and pads. Common physical treatment methods include mechanical crushing, mechanical separation, etc. Mechanical crushing and sorting equipment can crush PCB into small particles, and sort and recycle the materials through air flow sorting screens, electrostatic separators, etc.
Chemical treatment of PCB
After physical treatment, the electronic components after the PCB has been removed need to undergo chemical treatment to separate and recover the useful metals. For example, chemical processing in precious metal refining equipment includes steps such as soaking, dissolution and electrolysis. First, the PCB particles are soaked in a chemical solution that separates the useful metals from other materials. The useful metals in the solution can then be electrolytically deposited on the electrodes for recycling.
Reuse and resource recovery
After the above-mentioned treatment process, the recovery system can obtain high-purity metals such as copper, silver and gold. These metals can be used to produce new electronic devices or other industrial applications. In addition, the recycling system can also recover other usable resources in discarded PCBs, such as plastics and fiberglass.
The Pilot scale PCB recycling system achieves efficient recycling and processing of discarded PCBs through a series of technical processes. This not only helps reduce environmental pollution, but also recycles valuable metals and other resources, promoting sustainable development. The PCB recycling system developed by SUNY GROUP uses a series of technical processes to effectively recycle and process discarded PCBs, and can be customized according to customer needs while reducing negative impact on the environment.
