The manufacturing method
of recycled rubber
1. Introduction

With the acceleration of industrialization and the improvement of environmental awareness, the utilization of renewable resources has gradually become a research hotspot. As an important raw material for chemical production, recycled rubber has high economic value and environmental value. In this paper, the manufacturing method of recycled rubber is discussed in detail.

2. the definition and classification of recycled rubber

recycled rubber refers to a certain process, the waste rubber products are processed, so that it has the value of a class of rubber materials. According to the different sources and processing methods of waste rubber, reclaimed rubber can be divided into mechanical reclaimed rubber, thermal cracking reclaimed rubber and chemical reclaimed rubber.

3. recycled rubber manufacturing method

1. mechanical method of recycled rubber manufacturing method

mechanical method of recycled rubber is through mechanical force, the waste rubber products tearing, crushing, grinding and other physical methods, so that it becomes small granular recycled rubber. The advantages of this method are simple process, low cost, and good environmental protection, but the quality and performance of reclaimed rubber are poor, and it is mainly used for some low-demanding rubber products.

2. The manufacturing method of thermal cracking reclaimed rubber

thermal cracking reclaimed rubber is to break the macromolecular chain in waste rubber by high temperature cracking, so as to obtain reclaimed rubber. The advantage of this method is that the quality of reclaimed rubber is better, and it can be used for some rubber products with higher requirements, but the disadvantage is that the equipment investment is large, the energy consumption is high, and the environmental protection is poor.

3. Manufacturing method of chemical method recycled rubber

chemical method recycled rubber is to break the cross-linking bonds in waste rubber through chemical action to make it a plastic recycled rubber. The advantage of this method is that the quality and performance of the reclaimed rubber is better, it can be used for some high-demand rubber products, and the environmental protection is better. The disadvantage is that the process is more complex, need to add some chemical reagents, the cost is higher.

4. the application field of recycled rubber

recycled rubber is widely used in the production of rubber products such as tires, hoses, tapes, rubber shoes, seals, etc. It can be used as an important chemical production raw material to improve the utilization rate of resources, Reduce production costs, and also benefit environmental protection.
Precautions for manufacturing recycled rubber of
5.

In the manufacturing process of recycled rubber, the following issues need to be paid attention to:

1. The source and quality of waste rubber should be stable and reliable, and the use of waste rubber containing harmful substances should be avoided;
2. The manufacturing process should be reasonable to ensure the quality and performance of reclaimed rubber;
3. Pay attention to environmental protection and safety issues during the production process, avoid hazards to the environment and personnel.

6. conclusion

recycled rubber as an important raw material for chemical production has high economic value and environmental value. In the manufacturing process, it is necessary to choose the appropriate manufacturing method according to the source and processing method of waste rubber, and pay attention to environmental protection and safety issues. Through reasonable manufacturing process and stable and reliable source of raw materials, we can produce recycled rubber with high quality and reliable performance, which provides important raw material support for chemical production and contributes to environmental protection.
