As the application of aluminum composite panels becomes more and more extensive, the waste aluminum composite panels generated are also increasing. Because aluminum and plastic are stuck together, they cannot be used for aluminum recycling or plastic production, but can only be used as garbage. Incineration not only increases environmental pollution but also wastes a lot of resources. Method 1. The discarded aluminum-plastic panels are mechanically pulverized and heated and melted to make flowerpots or sewage pipes. Obviously, this method has a low recovery rate of aluminum and plastics; The second method is to burn the aluminum composite panel to burn off the plastic and leave the aluminum material, but this will produce a large amount of polluting gas, which will directly pollute the environment, and will also oxidize part of the aluminum during high temperature incineration, which will bring difficulties to regeneration; Method 3. Using a thermal plasma furnace, the aluminum and plastic are uniformly vaporized at a high temperature of 15,000 to 50,000 degrees, and the aluminum component sinks and casts into an aluminum ingot. huge investment; Method 4. Soak the discarded aluminum-plastic board in a solution containing separated substances, and use the separated substances to penetrate the plastic film and dissolve the aluminum layer, thereby separating the aluminum foil from the plastic film. Strong acids and strong alkalis will pollute the environment, cause corrosion to equipment, and also cause dissolution of the aluminum layer, which is not easy to implement industrially.
