What Are The PCB Recycling Technologies?

In today’s highly digitalised era. Circuit board (PCB) as the core component of electronic equipment. Its importance must be understood by everyone. In the daily life of computers, television sets, watches, collection, electrical equipment, automation equipment, medical equipment, etc. PCB circuit boards play a key role in connecting and supporting. With the continuous progress of science and technology and the rapid iteration of products. The problem of recycling and disposal of waste circuit boards is becoming more and more prominent. Became a pending environmental and resource challenges.

Waste circuit board disposal has become a difficult problem. Its complex composition structure and potential risk of pollution. pcb boards are distributed with sophisticated circuit patterns. It contains many valuable metals: copper, gold, silver, tin and so on. Non-metals: plastic fibres, welcome resins, glass fibres, etc. Of course there are also harmful substances: lead, mercury and other heavy metals. If these treatment components are not properly handled. Casually discarded and landfill. It will cause serious pollution to the soil, water the whole ecosystem. The metal resources in the waste PCB have a high recycling value. If effectively recycled and reused. It can link the problem of resource shortage. Promotes the development of circular economy.

Waste PCB circuit board recycling and processing technology

1. Physical sorting method: circuit board recycling machine will be used circuit boards through crushing, screening, gravity sorting, magnetic separation, electrostatic sorting and other steps. Thus, the metal and non-metal components in the waste PCB are separated. This recycling method is convenient to operate and has low processing cost. But its separation efficiency is greatly affected according to the difference of different Pcb composition. Otherwise, it is difficult to deal with the removal of metal residues in non-metal.

2. Chemical dissolution method: through a specific chemical solvent or acid, alkali solution. Dissolve the metal components in the waste PCB. Then through electrolysis, precipitation and other processes to achieve recovery. This process has a high recovery rate. Can be effectively recycled. Realise the complete separation of metal and non-metal. If the waste liquid is not properly treated in the process. It is easy to cause secondary pollution.

3. Biological method: in recent years. This method is more concerned. The use of microorganisms and enzymes and other biocatalysts. Selective adsorption and transformation of metal metal ions in the waste PCB. Realise the recovery of metals. Biological method is environmentally friendly, low energy consumption and other advantageous features. However, such process is still in the research stage. It is still relatively immature.

Through the above steps, you can effectively recycle and dispose of PCB circuit boards. You can contribute to the cause of environmental protection. Circuit board recycling not only helps to reduce the environmental pollution of electronic waste. It can promote the sustainable use of resources. With the metal of technology and environmental awareness. Circuit board PCB recycling methods and technology will continue to optimise and improve. Achieve a more efficient and environmentally friendly recycling process.
