The aluminum-plastic composite panel is composed of a polyethylene (PE) core material and two-sided aluminum panels. It is mainly used on the external walls of buildings. The thickness of the panel is usually 5mm. It has excellent rigidity, lighter weight, and is very easy to install. Architecturally.
Aluminum-plastic composite panels can be normally used in buildings for several decades. Therefore, the recycling of aluminum-plastic composite panels is more of a waste in the production and processing of new panels.
Recycling of materials A problem faced by manufacturers of aluminum-plastic composite boards is the recovery of waste boards produced during production, and the main problem is how to economically separate the aluminum panels from the PE cores. One method is to separate the aluminum-plastic composite board into small pieces first after separating the aluminum-plastic composite board into a small piece; another method for effectively recovering the large-size board is to separate the aluminum from the plastic by rolling. The aluminum part can be recycled as a single material and re-rolled. The PE part can be used for the production of the composite board after simple finishing. The scrap plates produced during the assembly and installation of composite boards can be recycled by the manufacturer.
The plastic part heat recovery method is because the waste product market is a free market, and some companies use Other methods to recycle aluminum plastic boards. The aluminum-plastic composite board is first shredded, and then the fragment is heated in a closed hot furnace until it is melted and finally evaporated. The energy generated during the evaporation process is used for the new melting evaporation process, and the aluminum material is further recycled. This recycling can produce benefits, so scrap aluminum composite panels can be sold for a certain price, there is no need to throw away.
Recycling of old scrap: In general, aluminum-plastic composite panels are used in large buildings. When the building is demolished, tons of discarded panels with significant economic use value will appear. That is to say, even if there is no regulatory requirement, the resulting scrap board will be recycled by the above method without being left behind, causing environmental pollution.
Under sunlight, the molecular structure of plastics will change over time and the quality will be reduced, but this situation is not suitable for aluminum-plastic composite panels because polyethylene is completely covered by the surface aluminum plate and can be protected from sunlight.
When using different recovery methods, the environmental indicators of products and their curtain wall systems are evaluated in accordance with the requirements of EN ISO 14040. A life assessment system (LCA) is used to compare the environmental impact indicators of aluminum-plastic composite panels and pure aluminum panel curtain walls. The aluminum-plastic composite panel curtain wall takes into consideration five different recycling methods, including the recovery and incineration of polyethylene cores (with or without the use of combustion heat). Due to its high recovery rate and reuse of aluminum materials, its environmental indicators are very high. of.
