Aluminum-plated paper recycling and eluting device

Abstract

The invention discloses an aluminized paper recycling and eluting device which comprises an eluting box and a bearing box, two sets of partition plates are arranged in the eluting box, a sealing plate is further connected between the two sets of partition plates, an inert solvent and a degumming agent are arranged in a sealing cavity and an eluting cavity respectively, a telescopic rod is arranged in the eluting box, the end of the telescopic rod is connected with a supporting plate, and the supporting plate is connected with the bearing box. According to the aluminized paper recycling and eluting device, the sealing cavity and the eluting cavity are arranged, an inert solvent is arranged in the sealing cavity to serve as a transition area between the inlet and the eluting cavity and between the outlet and the eluting cavity, the sealing cavity and the eluting cavity are separated from each other, and therefore the aluminized paper recycling and eluting device can be used for recycling aluminized paper. In the whole process, the degumming agent in the elution cavity cannot make contact with the external space, so that the degumming agent can be effectively prevented from being volatilized to the outside, meanwhile, due to the fact that the densities of the two solutions are different, the degumming agent can be separated from the bearing box in the inert reagent, and the degumming agent is further prevented from influencing operators and the environment.

Description

technical field [0001] The invention relates to the technical field of aluminized paper, in particular to a recycling and eluting device for aluminized paper. Background technique [0002] Aluminized paper is mainly composed of base paper, aluminum layer and coating. Because of its good gloss and smoothness, good flexibility, high fastness of the aluminum sprayed layer, beautiful and environmentally friendly, and good printing performance and machining performance, it can be widely used It is used for exquisite packaging of tobacco, alcohol, bottle stickers, tea, food, cosmetics, daily chemicals, department stores, gifts, handicrafts and other products, and can also be used for building decoration materials. [0003] Vacuum aluminum-coated paper can be divided into direct evaporation method and transfer evaporation method according to its production process. Among them, the transfer evaporation method is to glue the PET film after vacuum aluminum plating and compound it wit...

AI Technical Summary

Problems solved by technology

The transfer evaporation method is divided into full-format transfer and partial transfer. After the aluminized film is partially transferred and peeled off, the aluminized layer and the adhesive layer remain on the film surface, which cannot be reused and can only be treated as a waste film, causing serious environmental pollution and waste of resources

[0004] The existing reuse of the paper film in the production process of aluminized paper is eluted by a degumming agent, thereby increasing the contact between the solution and aluminum, and the degumming agent is toxic and volatile, so it needs to be removed during the elution process. Carry out the sealing operation, but no matter what the sealing is, the degumming agent or volatilized degumming agent will always be carried in the process of taking out the film, which is not good for the operator and the environment
