Method for separating aluminum foil and plastic film from scrap aluminum film

【Abstract】 A method for separating aluminum foil and plastic film from aluminum scrap is a method to treat industrial and domestic wastes, avoid environmental pollution, recycle aluminum foil and plastic film in waste aluminum film, and turn waste into treasure. Mainly after soaking in cold water, the solvent prepared from tetrahydroanthraquinone, tetrahydrofuran and glacial acetic acid is automatically separated in cold water after being soaked in the reaction kettle for a long period of time. At present, there are more than 10,000 tons of discarded aluminium film used for packaging tablets in pharmaceutical companies across the country. The previous treatment method was incineration or landfill. If treated by the method described in the present invention, it can create an annual profit and tax of more than 76 million yuan, which can be created. There are more than 6,000 job opportunities. No industrial wastewater or waste gas will be generated during the separation process. This will not only avoid pollution to the atmosphere after burning or landfill, but also produce good economic and social benefits. The method is simple and easy to learn, the solvent can be recycled, the processing cost is low, and it is suitable for separating various waste aluminum films.
