The manufacturing method
of polyethylene recycled materials
1. Introduction

With the continuous expansion of chemical production scale and the increasing shortage of resources, the manufacture of polyethylene recycled materials has gradually become a research hotspot in the industry. Polyethylene recycled materials can not only effectively use waste polyethylene materials, reduce production costs, but also improve the utilization of resources and reduce environmental pollution. This paper will discuss the manufacturing method of polyethylene recycled material.

2. Polyethylene Recycled Materials Manufacturing Methods

1. Cleaning and Classification

First of all, the collected waste polyethylene materials need to be cleaned and classified. Cleaning is to remove oil and impurities on the surface of the material, and classification is to distinguish different types of polyethylene materials for subsequent processing.

2. Crushing and mixing

The cleaned and classified polyethylene material needs to be crushed and mixed. Crushing is to decompose large pieces of material into small pieces to facilitate subsequent processing; mixing is to fully mix different types of polyethylene materials to ensure uniform quality of recycled materials.

3. Plasticizing and Extrusion

The crushed and mixed polyethylene material needs to enter the plasticizing extruder for plasticization and extrusion. In the process of plasticizing extrusion, the polyethylene material is plasticized into a molten state by the action of high temperature and high pressure, and then the recycled material is extruded through the extruder head.

4. Cooling and pelletizing
Polyethylene regenerants
extruded from the extruder head need to be cooled and pelletized. Cooling is to make the recycled material solidify quickly and maintain its shape and structure; cutting is to facilitate subsequent storage and transportation.

3. manufacturing process need to pay attention to the problem of

1. control temperature and pressure

in the plasticizing extrusion process, the need to control the temperature and pressure, to ensure that the polyethylene material can be fully plasticized, while avoiding excessive temperature and pressure on the equipment damage.

2. Keep the equipment clean

During the manufacturing process, it is necessary to keep the equipment clean, and regularly clean up the debris and scale inside the equipment to ensure the normal operation of the equipment and the quality of the product.

3. Strictly control the quality of raw materials

the quality of raw materials for the manufacture of polyethylene recycled materials has a vital impact on the quality of the final product. Therefore, when collecting raw materials, it is necessary to strictly control the quality of raw materials to avoid mixing impurities and unqualified raw materials.

4. Conclusion

In short, the manufacturing method of polyethylene recycled materials requires the steps of cleaning and sorting, crushing and mixing, plasticizing and extruding, and cooling and pelletizing. In the manufacturing process, it is necessary to pay attention to controlling temperature and pressure, keeping equipment clean, and strictly controlling the quality of raw materials. Through reasonable manufacturing methods and strict control measures, high-quality polyethylene recycled materials can be manufactured to provide sustainable solutions for the production of chemical products.
