MICROWAVE-BASED CHEMICAL RECYCLING TECHNOLOGY RESEARCH FOR WASTE PCB
Because epoxy condensate can be completely decomposed in nitric acid solution, the glass fiber and epoxy resin in PCB can be fully recycled through this way and much more value can be obtained from the waste PCB. However, the decomposition efficiency is low, and several resultants are very toxic to human 0 . To solve this problem, this paper studied the decomposition efficiency of the non-metallic powder from PCB and the resultants by using microwave as an assistant tool. First of all, through a series of experiments, find the best reaction conditions without the assistant of microwave. Then, study the acidolysis of the non-metallic powder with the assistant of microwave through the orthogonal experiments. An analysis on the composition of reaction resultants was done, the result showed that the assistant of microwave changed the chemical reaction of degradation, and also improved the reaction efficiency.
