The manufacturing method
of recycled PC
1. Introduction

With the expansion of chemical production scale and the increasing shortage of resources, recycled PC has gradually become an important raw material for production. Recycled PC has the advantages of saving resources, reducing costs and reducing environmental pollution, so it has attracted much attention. This article will introduce a common method of manufacturing recycled PC.

2. Materials and Methods

1. Material

The main raw material of recycled PC is waste PC plastic products, such as waste computer shells, CD discs, etc.

2. Equipment

recycling PC manufacturing needs to use equipment including crusher, washing machine, extruder and so on.

3. Manufacturing method

(1) Crushing: Crushing waste PC plastic products to make them small pieces or powder.

(2) cleaning: cleaning the broken PC material to remove the oil, dust and other impurities.

(3) Drying: The cleaned PC material is dried to ensure that its water content reaches a certain standard.

(4) Extrusion: The dried PC material is added to the extruder, and is melted again and a new PC material is formed by the action of high temperature and high pressure.

(5) Granulation: The extruded PC material is cooled and cut into granules of a certain length to facilitate subsequent processing.

3. Results and Discussion

1. Yield and Quality

Using the above manufacturing methods, about 0.8-0.9 tons of recycled PC materials can be produced per ton of waste PC plastic products. After testing, the physical properties and chemical indicators of recycled PC materials have reached the relevant national standards, which can meet the needs of most chemical products production.

2. Influencing factors

In the manufacturing process of recycled PC, factors such as crushing particle size, cleaning effect, drying degree, extrusion temperature and pressure will affect the quality and yield of the final product. Therefore, it is necessary to strictly control the process parameters of each link to ensure the stable and reliable quality of the recycled PC material.

4. conclusion

can successfully convert waste PC plastic products into recycled PC materials through the above manufacturing methods, which provides an important raw material source for chemical production. At the same time, the manufacturing of recycled PC also has good economic and environmental benefits, which can contribute to the development of circular economy and the conservation of resources.

5. Outlook and Suggestions

With the continuous progress of technology and the expansion of the scope of application, the manufacture of recycled PC will become more and more popular and important. In the future, we can further explore and study how to improve the output and quality of recycled PC, reduce costs, improve production efficiency, and expand its application fields. At the same time, it is also necessary to strengthen policy support and supervision, standardize the order of the recycled PC manufacturing industry, and ensure that its healthy development and environmental protection requirements are fully met.
