How to deal with industrial solid waste of waste printed circuit boards
With the development of the electronics industry, a large number of printed circuit boards that have reached the end of their life have begun to be scrapped. So how is the solid waste of the waste printed circuit board industry handled? Today I will take you to find out.
How to deal with industrial solid waste of waste printed circuit boards
As the most active electronic component, Huaqiu circuit board is included in almost all electronic products, especially in computers, large-scale communication equipment, and military products, where it accounts for a high proportion. Therefore, the number of discarded circuit boards is directly proportional to the increasing amount of electronic waste. So how to deal with the solid waste of the waste printed circuit board industry? What is industrial solid waste? Let’s take everyone to learn about these solid waste safety tips.
Although waste printed circuit boards are a kind of industrial solid waste. However, the metal content of the circuit board accounts for about 50%, and the content of copper alone is 20%. In addition, there are a small amount of precious metals and rare metals. The potential value of some metals of waste circuit boards with medium metal content converted according to market prices is very impressive. 1 ton of gold ore contains more than 2 grams of gold, which has mining value, and 1 ton of discarded circuit boards contains 99.999% gold of 80 to 1500 grams. Compared with the value obtained from traditional metal mining and processing, It is much easier to extract various rare metals from discarded circuit boards than to mine, so it is well-deserved to be called a “gold mine”.
In addition to a large amount of metal, waste circuit boards also contain a large amount of high molecular polymer materials directly or indirectly derived from petroleum products, which have a high calorific value. They can be used to generate energy and produce related chemical products. Some foreign scientists have applied pyrolysis to study the feasibility of recycling organic matter and inorganic fillers in resin; Zheng Zhihe of the Taiwan Industrial Technology Research Institute of my country introduced the use of non-metal and wood chips in waste circuit boards to mix in a certain proportion to produce qualified and safe The method of PVC floor tiles. Therefore, the potential value of discarded circuit boards is very high.
