Manufacturing Methods
of Recycled Plastics
1. Introduction

With the increasing attention to environmental protection and resource utilization, recycled plastics are more and more widely used in the field of chemical production raw materials. The manufacture of recycled plastics can not only improve the utilization rate of waste plastics, reduce production costs, but also reduce environmental pollution. This article will detail the manufacturing methods of recycled plastics, including pretreatment, crushing, cleaning, drying, granulation and quality control steps.

2. the manufacturing steps of recycled plastics

1. Pretreatment

pretreatment is the first step in the manufacture of recycled plastics, the main purpose is to sort waste plastics and remove impurities. Different types of waste plastics require different treatment methods, so correct classification is the key. Common pretreatment methods include manual sorting and mechanical sorting.

2. Crushing

After pretreatment, the waste plastic needs to be broken into small pieces for subsequent cleaning and granulation processes. Crushing equipment can be selected according to the type and size of waste plastics. Common crushing equipment includes hammer crushers, shear crushers, etc.

3. Cleaning

cleaning is to remove oil, dust and other impurities in waste plastics. Cleaning methods and equipment can be selected according to the type of waste plastics and the degree of pollution. Common cleaning methods include mechanical cleaning and chemical cleaning.

4. Drying

The cleaned waste plastic needs to be dried to reduce its water content and facilitate the subsequent granulation process. The drying method can be selected according to the characteristics and requirements of waste plastics. Common drying methods include natural drying and hot air drying.

5. Granulation

granulation is the process of processing dried waste plastics into granules for easy storage and transportation. The method and equipment of granulation can be selected according to the type and characteristics of waste plastics. Common granulation methods include extrusion granulation, strip cutting, etc.

6. Quality control

In order to ensure the quality of recycled plastics, quality control is required. Common quality control methods include appearance testing, density testing, melting point testing, and strength testing. Only recycled plastics that meet certain standards can be used in chemical production raw materials.
Precautions in the manufacture of
3. recycled plastics

1. The source and quality of waste plastics must be stable and reliable to ensure the quality of recycled plastics and the stability of the production process.
2. In the process of crushing, cleaning, drying and granulation, it is necessary to select appropriate equipment and methods according to different types and characteristics of waste plastics.
3. Pay attention to environmental protection and safety during the production process to avoid harm to the environment and operators.
4. The production process needs to be fully monitored to ensure product quality and production efficiency.

4. conclusion The manufacture of

recycled plastics is an important environmental protection and resource utilization work, which can improve the utilization rate of waste plastics, reduce production costs and reduce environmental pollution. Through reasonable pretreatment, crushing, cleaning, drying, granulation and quality control steps, high-quality recycled plastics can be produced, providing a reliable source of raw materials for chemical production.
