Can waste ACP aluminum composite panels be recycled?

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. Although aluminum and plastic are materials that can be reused through processing, aluminum and plastic are mixed together in aluminum-plastic panels, which brings great difficulties to recycling. There are several ways to recycle aluminum and plastics in aluminum composite panels:

Method 1. The discarded aluminum composite 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 away the plastic and leave the aluminum material, but this will generate 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.

Method 5. The recycling process of environmentally friendly waste aluminum-plastic panels. The waste aluminum-plastic panels are sent to the crushing equipment for crushing, and the crushed particle size is less than 12mm, and then sent to the grinding device for grinding; sent to the vibration screening equipment for screening, from the vibration screening equipment The separated materials with a particle size of not more than 3mm are separated into aluminum powder and plastic by electrical separation equipment, and the materials with a particle size of more than 3mm separated from the vibration screening equipment are the plastic protective film part;

SUNY GROUP environmental protection aluminum-plastic separator The main steps of the process of environmentally friendly recycling of waste aluminum-plastic panels are waste aluminum-plastic panels → crushing → grinding → screening → electric separation, which can separate plastic and aluminum powder; the technology does not use strong acid and aluminum powder in the entire separation process. There is no incineration process for strong alkali and highly polluting substances. The whole process adopts automatic control, which saves labor and improves work efficiency. The separated plastic part can be directly used to make plastic products, and the separated aluminum powder part can be directly used for preparation Industrial aluminum powder makes waste aluminum-plastic panels re-utilized as resources, avoids environmental pollution caused by direct disposal of waste aluminum-plastic panels, conforms to sustainable development strategies, has outstanding economic and social benefits, and can also be used for other waste aluminum-plastic panels Separation of products and copper-plastic products.
