The manufacturing method
of plastic runway
1. Introduction

plastic runway because of its excellent performance, such as durability, simple maintenance, comfortable use, etc., has been widely used in various sports venues. This article will introduce the manufacturing method of plastic runway in detail, covering the key links such as raw material selection, mixing and molding.

2. raw material selection

manufacturing plastic runway main raw materials including rubber particles, polyurethane glue, catalyst, pigment and so on. Among them, rubber particles are the main components and need to provide good elasticity and durability; polyurethane glue is used to bond rubber particles and requires excellent weather resistance and chemical resistance; catalyst is used to accelerate the curing of glue and improve efficiency; Pigments are used to adjust the color of the runway.

3. mixing process

1 ingredients: according to a certain proportion of rubber particles, polyurethane glue, catalyst, pigment and other raw materials ready.
2. Mixing: Use special mixing equipment to fully mix the ingredients to ensure that all kinds of raw materials are fully mixed.
3. Testing: The quality of the mixed material is tested to ensure that its performance meets the preset standards.

4. molding process

1. Laying: Laying the mixed material on the basis of the predetermined runway, paying attention to controlling the thickness and flatness.
2. Compaction: Use special compaction equipment to compact the laid material to improve its compactness and durability.
3. Curing: Under appropriate temperature and humidity conditions, let the paved runway cure naturally, or use a catalyst to accelerate curing.

5. post-treatment process

1. Trimming: Trim the formed runway to ensure that its edges are neat and meet the requirements of use.
2. Cleaning: Clean the surface of the runway to remove excess impurities and stains.
3. Maintenance: Maintain the runway regularly and keep it in good condition.

6. quality control

In the manufacturing process, it is necessary to strictly control the quality of each link to ensure that the final product meets relevant standards. This includes the quality of raw materials, the control of the mixing process, the control of the molding process, and the quality of the post-processing process. At the same time, each step of the process needs to be quality checked and recorded to facilitate tracking and solving problems.

7. environmental protection and safety

in the process of manufacturing plastic runway, need to pay attention to environmental protection and safety issues. Try to choose environmentally friendly, non-toxic raw materials to avoid harm to the environment and personnel. At the same time, in the production process, it is also necessary to strictly abide by the relevant safety regulations to ensure the smooth progress of the production process.

8. Conclusion The manufacturing of

plastic runway involves multiple links and processes, and the quality of each link needs to be strictly controlled to ensure the performance and service life of the final product. At the same time, it is also necessary to pay attention to environmental protection and safety issues to ensure that the production process meets relevant regulations and standards. Through scientific manufacturing methods and strict quality control, high-quality, safe and environmentally friendly plastic runways can be manufactured, providing a good use experience for various sports venues.
