How to separate aluminum and plastic in aluminum-plastic panels?

Separating aluminum and plastic is a task that requires specialized technology and equipment. The following are several methods to achieve separation of aluminum and plastic:
1. Physical separation method: Separate aluminum and plastic through physical methods. A common method is to use a vibrating screen to break the waste aluminum-plastic panels into small pieces, and then separate the aluminum and plastic through the vibrating screen. In addition, wind sorters can also be used to separate aluminum and plastic by wind force, taking advantage of the density difference between them.
2. Chemical separation method: Separate aluminum and plastic through chemical reaction. Put the waste aluminum-plastic panels into a high-temperature smelting furnace and add an appropriate amount of acid or alkali to cause a chemical reaction between aluminum and plastic to separate them. However, this method requires the use of a large amount of chemical reagents and can easily cause environmental pollution.
3. Thermal separation method: Aluminum and plastic are separated by heating. Put the waste aluminum-plastic panels into a hot melting furnace and heat it to the melting point of the plastic to melt the plastic and separate it from the aluminum. This method requires the use of high-temperature equipment and strict control of temperature and time to ensure complete separation of aluminum and plastic.

Regardless of the method used, the separated aluminum and plastic can be recycled and reused. Recycled aluminum can be used to make new aluminum products, and recycled plastic can be used to make new plastic products. By realizing the separation of aluminum and plastic from waste aluminum-plastic panels, it can not only reduce the consumption of natural resources, but also reduce environmental pollution and achieve sustainable development.
