The manufacturing method
of recycled PE
1. Introduction

With the rapid development of the plastics industry, polyethylene (PE) has become a widely used raw material for the production of chemical products. However, waste PE products cause serious pollution to the environment. Therefore, it is of great practical significance to study the manufacturing method of recycled PE. This article will introduce the manufacturing method of recycled PE in detail, aiming to provide an environmentally friendly, economical and efficient production method.

2. the raw material source of recycled PE

The raw material of recycled PE mainly comes from waste PE products, such as plastic bags, packaging films, containers, etc. These waste products can be used as raw materials for recycled PE after pretreatment such as classification, cleaning and crushing.

3. recycled PE manufacturing steps

1. pretreatment
will collect waste PE products classification, remove the metal, paper and other impurities. Then, clean the waste PE products with clean water to remove the oil and dust on the surface. Finally, the cleaned waste PE products are broken into small pieces to facilitate subsequent processing.
2. Melt granulation
The pre-treated waste PE fragments are added to the extruder, and the waste PE fragments are melted by heating and screw extrusion. Then, the molten PE is extruded into strips through a die, and after water cooling, it is cut into pellets of a certain length. This process can convert waste PE fragments into reusable PE particles.
3. Sieving and packaging
Sieve the granulated PE particles to remove impurities and unqualified particles. The sieved regenerated PE particles are then packaged for storage and transport.

4. recycled PE manufacturing precautions

1. Control temperature
In the process of melting granulation, it is necessary to control the appropriate temperature to ensure that the waste PE fragments can be fully melted, while avoiding the degradation of PE at high temperature.
2. Regular maintenance of equipment
extruders and other equipment need regular maintenance to ensure the normal operation of the equipment and the quality of the product.
3. Comply with environmental protection requirements. During the production process,
need to comply with environmental protection requirements and treat the waste gas and waste water generated to reduce the impact on the environment.

5. the application field of recycled PE

recycled PE can be widely used in various fields, such as plastic bags, packaging films, pipes, profiles, etc. Compared with native PE, recycled PE has a price advantage, and can improve the utilization of resources and reduce environmental pollution. Therefore, recycled PE has broad application prospects in the field of chemical production raw materials.

6. conclusion

the manufacturing method of recycled PE is of great significance for improving resource utilization, reducing environmental pollution and reducing production costs. In the actual production process, it is necessary to optimize according to the source and quality of raw materials, equipment performance and other factors to improve the quality and output of recycled PE. At the same time, strengthening the R & D and application of recycled PE will help improve the sustainable development level of the plastics industry.
