Description

Plastic deco sheet peeling device < RTI ID = 0.0 >

The present invention relates to a plastic deco sheet peeling apparatus, and more particularly, to a plastic deco sheet peeling apparatus which is capable of heating a plastic decorative sheet in a rolled state in which different kinds of materials are laminated, And separating the separated sheets from each other, thereby enabling to recycle the separated sheets of different types.

In the case of plastic decorative sheet products laminated with different kinds of materials laminated, they are widely used for exterior coating of products throughout the industry.

Use of the above-mentioned plastic decor sheet can improve the appearance of the product at low cost, and can provide various designs.

However, in the case of a plastic decor sheet formed by laminating different kinds of materials such as polyethylene (PE), polypropylene (PP), polystyrene (PS), vinyl chloride (PVC), vinylidene chloride (PVDC) There are disadvantages that are impossible.

In other words, in the case of defective products or stocks in the production process, they are discarded without being reused. Since the two materials are formed together in an adhesive state, they can not be used as recycled materials, so they are buried after incineration or crushing.

However, in the case of incineration or landfilling as described above, there were problems such as waste disposal cost, invention, air pollution, soil pollution, waste of energy, and the like.

In recent years, some technologies have been proposed that can be reproduced without incineration or landfill, and a representative example thereof is a method of recycling a multilayer waste film for packaging of Korean Patent Registration No. B1-05 (1996) 15-0528646 Comprising: a) a multi-layer packaging film for wrapping comprising a ground aluminum layer, wherein the multi-layer packaging film for wrapping comprises a plastic layer comprising a polypropylene, a polyethylene and a polyester and an aluminum layer, Selectively dissolving and separating the aluminum layer by treating with a dissolving liquid; b) separating the pulverized product in which the aluminum layer is dissolved and the layer separated from the pulverized product mainly composed of the polypropylene and polyethylene layer having a small specific gravity and the polyester layer having a high specific gravity as the main component, c) drying the pulverized material having a large specific gravity mainly composed of the polyester layer separated by the difference in specific gravity, and then feeding the pulverized material to the reactor and heating the pulverized material together with the organic solvent to dissolve and separate the polypropylene and polyethylene as the subcomponents; And d) separating and recovering the aluminum component, the polypropylene-polyethylene mixture and the polyester from the separated product, respectively. This requires a reactor which is a high-priced equipment and requires a high degree of technicality, such as a process of melting and recovering the melt.

Another example is a method and an apparatus for regenerating a composite film of Korean Registered Patent Application No. B1-0-0908605 (Mar. 24, 2004). In this case, a composite film having a plurality of layers of different materials A process and means for separating the layers constituting the piece to be processed into layers for each layer by adding an impact grinding force to the individual pieces of the processed pieces to be processed, , The processed material recovered through the peeling and separation process is subjected to the wind-force separation process so that the layers recovered in the mixed state can be separately sorted and recovered.

Such a method and apparatus for regenerating a composite film has a problem in that the purity of the selected recovered product is lowered and the quality of the regenerated raw material is deteriorated although it has a large amount of processing ability.
