What is the processing of waste printed circuit boards?
Hebei Cangzhou Lida circuit board factory mainly produces single-sided circuit boards, circuit boards, aluminum circuit board, PCB circuit board, circuit boards, LED circuit board and multi-layer circuit board, and is widely used in aerospace, defense, communications, home appliances, environmental protection, medical and industrial control field.
The second aspect is the pyrolysis, pyrolysis is in heating condition and inert atmosphere of waste thermosetting epoxy resin circuit board processing substrate is decomposed into oligomers and small molecular weight compounds, gas or other organic compounds, but the recovery of gas and liquid due to heat value is low and difficult to use as fuel or for other chemical raw materials.
Non metal powder as a filler is a very good method, but need to consider the depth of grinding, cost, dosage, dust pollution and other issues, if you can find a good solution, will have broad prospects for development.
Waste circuit board processing is mainly the removal and grinding, these methods need to be non-metallic powder fully crushed, easy to produce dust and toxic gas and pollute the environment, and high cost.
