The nature and use
of regenerated EPS in the field of raw materials for chemical production
Abstract:

This paper studies the nature and use of regenerated EPS in the field of raw materials for chemical production. Through the analysis of the physical and chemical properties of recycled EPS, its application in the fields of thermal insulation materials, building materials, packaging materials, etc. is discussed, and compared with other raw materials. The results show that the regenerated EPS has excellent properties and a wide range of applications, and is an important raw material for chemical production.

1. Introduction

With the development of economy and the improvement of people's living standards, the number of waste plastics is increasing, of which EPS(Expandable Polystyrene, expandable polystyrene) is a common waste plastic. In order to realize the effective use of resources and environmental protection, recycled EPS has gradually become a research hotspot in the field of chemical production raw materials. The purpose of this paper is to explore the nature and use of recycled EPS in the field of raw materials for chemical production.

2. properties of regenerated EPS

1. physical properties: regenerated EPS has the characteristics of light weight, low density, easy processing and so on. Its surface is smooth, with good thermal insulation performance and sound insulation performance.
2. chemical properties: regenerated EPS has good acid, alkali and oil resistance, but it is easy to decompose at high temperature.

3. use of recycled EPS

1. insulation material: recycled EPS has good thermal insulation performance, can be used in building exterior wall insulation, pipeline insulation and other fields, improve energy efficiency.
2. Building materials: recycled EPS can be processed into lightweight panels for building partitions, roofs and other parts to reduce the weight of buildings and improve seismic performance.
3. Packaging materials: Recycled EPS can be used to make packaging boxes, pallets, etc., with good cushioning performance, to protect the goods from damage during transportation. Comparison between

4. and other raw materials

Compared with traditional raw materials for chemical production, recycled EPS has the following advantages:

1. Rich resources: Waste EPS has a large number, a wide range of sources, and has a high recycling value.
2. Environmental protection: The use of renewable EPS can reduce the dependence on traditional petrochemical resources and reduce the impact on the environment during the production process.
3. Economy: The price of renewable EPS is relatively low, which can reduce production costs and improve the economic efficiency of enterprises.

5. conclusion

regenerated EPS has excellent properties and a wide range of uses in the field of chemical production raw materials, and can be used as an important production raw material. Through further research and improvement, the performance and added value of recycled EPS can be improved, and a more environmentally friendly, economical and efficient raw material selection can be provided for the chemical production industry. At the same time, strengthening the recycling and reuse of waste EPS is of great significance for promoting the development of circular economy and protecting the environment.

6. Suggestions and Prospects

In order to promote the application of recycled EPS in the field of raw materials for chemical production, the following measures are recommended:

1. Strengthen technology research and development: improve the production technology and processing equipment level of recycled EPS, and improve its performance and added value.
2. Improve the recycling system: establish a sound waste EPS recycling system to improve the recovery rate and utilization rate.
3. Strengthen policy guidance: the government should give certain policy support and preferential treatment to relevant enterprises to encourage the production and application of renewable EPS.

looking to the future, with the continuous progress of technology and the improvement of environmental awareness, the application prospect of recycled EPS in the field of chemical production raw materials will be broader.
