Pyrolysis of waste PCB circuit boards
Pyrolysis is the process of heating organic matter to a certain temperature under anoxic or anaerobic conditions to decompose it into gas, liquid (oil), solid (coke), and recycle it.
First remove the components on the circuit board, then smash the plate to a certain size and send it to the reactor for pyrolysis. Polymers such as epoxy resins are heated under inert gas to a certain temperature and undergo thermal decomposition to produce low molecular weight substances.
Pyrolysis oil has a complex composition, a large boiling point range and high calorific value, and has the properties similar to crude oil. Pyrolysis oil contains many valuable components, and if it can be rationally recycled, it will greatly improve the economy of the whole pyrolysis process.
