How to separate aluminum materials from packaging bags?

　　In order to better contact the aluminum plastic packaging bag with the solvent and speed up the separation, the waste aluminum plastic plates were cut into 1 cm before the experiment × 1 cm small pieces; Select several wide mouth reagent bottles, add about 50mL of solvent into each of them, label them, and place them at room temperature or in a constant temperature water bath at 50 ℃, 60 ℃ and 70 ℃ respectively according to the experimental needs, then immerse 10 pieces of the prepared aluminum plastic plates into the solvent.

　　Immerse and time, and record the experimental phenomenon. If the aluminum plastic packaging board can be separated in the relevant solvent, after the aluminum foil is separated from the plastic, the plastic and aluminum foil mixture will be stirred. The plastic will float on the liquid surface due to the low density, while the aluminum foil will sink under the liquid due to the high density. Use tweezers to remove the separated plastic and aluminum foil separately and dry them naturally. As required, use the remaining solvent to conduct the separation test of new aluminum plastic plate.

　　The aluminum plastic flexible packaging separation equipment was born from this, which can realize the decomposition and separation of aluminum plastic flexible packaging.

　　The main working principle is to recycle the aluminum plastic household garbage, and then crush and electrostatic separation. The particle size requirements are met by vibrating screening, and then the plastic and aluminum are separated by double roll electrostatic separator. The whole process is physical separation, without heating combustion water and chemistry, which will not cause secondary damage to the environment. The machine is highly automated, so it does not require much manpower, and the operation and maintenance of the machine are very simple. The recycled aluminum foil can be used to smelt aluminum ingots, and it is also the raw material for some aluminum materials and building materials.
