PREMABLE TO THE DESCRIPTION
The following specification particularly describes the nature of the invention and the manner in which it is to be performed.

NOVEL PROCESS TO RECYCLE XLPE [Cross linked Polyethylene]

Field of the Invention
This invention relates to a novel process to recycle this xlpe. The recycled material which further useful for making the products like frame, enclosures, pipes, different sections, tires for various applications are developed using innovated process.

Background of the invention
Cross-linked polyethylene material, also known as XLPE, is prepared by chemical crosslinking (crosslinking by oxide or silane) or irradiation cross-linking (irradiation plus irradiation line), which has high mechanical strength, high and low temperature resistance. Excellent creep resistance, widely used in communications, power cable sheathing materials, XLPE hot water pipes, automotive and electrical components and cross-linked foam materials. However, since XLPE is a thermosetting material, its properties are completely different from those of thermoplastic materials. The material is insoluble and infusible. Due to the lack of processing fluidity, it is difficult to directly form the reprocessing, whether it is chemical crosslinking or irradiation crosslinking. It is difficult to recycle and reuse. Cable replacement process and XLPE pipe production and installation process will produce a large number of cross-linked polyethylene wastes that are difficult to recycle. At present, landfill or incineration is mainly used, resulting in environmental pollution and waste of resources. Therefore, the development of new recycling technology for XLPE waste is an important research topic for resource recycling, energy conservation, recycling, recycling and environmental management.

The difficult recycling of cross-linked polyethylene is due to the cross-linking of its molecular chain, forming a three-dimensional network structure. Naturally, the recovery of cross-linked polyethylene can be achieved by recycling the cross-linked polyethylene, destroying its three-dimensional network structure, and depolymerizing the cross-linking structure between the molecular chains.

There are two methods for the destruction of chemical bonds, namely chemical methods and physical methods. The chemical method is to use chemical auxiliaries, such as organic disulfides, mercaptans, alkali metals, etc., at high temperatures, through these additives to attack and break the cross-linking bonds, so that the cross-linking bonds are broken, and these substances can also The broken active chain end is inertly sealed to avoid cross-linking of the broken cross-linking bonds, so that the cross-linked polyethylene is depolymerized into non-cross-linked polyethylene, which has flowability and processability, and can be recycled like thermoplastic polyethylene. . Chemical methods require the addition of chemical auxiliaries, the cost is increased, and a large amount of corrosive or toxic gases are generated during the depolymerization process, which is liable to cause secondary pollution. Therefore, chemical methods are not an environmentally effective method.

The physical method is to add no chemical substances, but use the applied energy to destroy the three-dimensional network structure of the cross-linked polyethylene, and form a linear linear or branched low-molecular-weight two-dimensional structure. The material has high temperature fluidity and can be processed. At present, microwave or ultrasonic methods are commonly used. Although physical methods do not cause secondary pollution due to the absence of chemical substances, and are relatively environmentally friendly, the equipment investment of these methods is large, and it is difficult to achieve continuous production, so the efficiency is very low. It is difficult to achieve in the field of large-scale industrial production, and most of them stay in the laboratory stage.

In view of the problems faced by existing methods for recycling XLPE waste, it is necessary to study new recycling methods that are efficient and have no secondary pollution.

Object of the invention
The main object of the present invention is to recover the xlpe waste, which is more provide more strength to the products prepared form the recycled material.

The method which is use to recycled has not use any chemical substance to recover so, the process is environment friendly.

BRIEF DESCRIPTION OF THE DRAWINGS
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings,
Fig. 1 represents the flow diagram of present invented method.
Fig.2 represents the Example of Xlpe Product I,e, Filter Press Plate

Detailed description of the invention
Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the construction and arrangement of parts illustrated in the accompanying drawings. The invention is capable of other embodiments, as depicted in different figures as described above and of being practiced or carried out in a variety of ways. It is to be understood that the phraseology and terminology employed herein is for the purpose of description and not of limitation.

As shown in Fig.1 , the present invention first to recycled xlpe, from the cables , in the present invention Cables are recycled to recover copper / aluminum metal [ cupper & aluminum are good conductor of electricity and easy to use and recycle]. While recycling of cables, the cinsulating material Xlpe is stripped off and collected separately by the present invented method and the cupper / aluminum is sent for further refining and melting. Since Polyethylene is cross linked, it is not possible to recycle.

The innovators have established a process / system to recycle this Xlpe and various useful products like frame, enclosures, pipes, different sections, tires for various applications are developed using innovated process.

In the present invented method different molds and tools are used to make useful products from Xlpe. The process is of compression molding. Compressive pressure and temperature is set as per the product to be manufacture. Mold filling, heating with pressure, cooling and de-moulding are the stapes followed with temperature range from -5 to 150 degree centigrade. Pressure is in the rage of 10 to 200 Kg/cm2 of pressing hydraulic cylinder. This pressure is also can be achieved by mechanical toggle clamps.

As shown in Fig.2, one example of Xlpe Waste product is shown which is Filter Press Plates.

In the Existence method Filter press is used as separating machine to physically separate liquid and solid from slurry since long time.
The filter press is of two main parts. Namely 1. Filter cloth and 2. Filter press plates. These plates hold filter cloth in position. These plates are also used to bear the clamping pressure while assembled to stop leakage of liquid between these plates and also to with stands the pumping pressure of slurry.

The plates used in filter presses were made originally form wood. Later on since last few years, these plates are made out of Polypropylene [PP] and other plastics. PP is an inert plastic to many of the chemicals and liquids for corrosion. PP is easily available at low price. There are other plastics being used for special applications,
In the present invention method waste of Cross linked Polyethylene [Xlpe] , is use to manufacture the “Filter press Plates”, where the Filter press plates made from Waste of Xlpe has following features.

• Xlpe plates will perform quell to PP plates
• Xlpe plates can be made of any size and shape as it is done with PP plates.
• Xlpe plates can be machined to achieve flatness and dimensional tolerance as compared to PP plates
• Xlpe plates costs much less.
• Xlpe waste dumping in environment will be reduced.
• Virgin resource of PP can be saved

While, the invention has been described with respect to the given embodiment, it will be appreciated that many variations, modifications and other applications of the invention may be made. However, it is to be expressly understood that such modifications and adaptations are within the scope of the present invention, as set forth in the following claims.
