Plastic runway construction processThe plastic track, also known as the all-weather track and field track, is composed of polyurethane prepolymer, mixed polyether, EPDM rubber particles or PU particles, and additives. The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which is conducive to the speed and skill of athletes, effectively improving sports performance, and reducing the rate of fall injuries. In recent years, with the development of sports and the importance of sports facilities in schools, plastic runways have become an indispensable hardware condition in sports facilities in primary and secondary schools. This article will introduce the construction process of plastic runway in detail.
1. Basic detection and processing.
Before construction, the foundation is first inspected to ensure that it meets the requirements. The foundation should have sufficient strength and stability, without obvious cracks, no water accumulation, etc. For foundations that do not meet the requirements, corresponding treatments need to be carried out, such as strengthening tamping, repairing cracks, etc.
2. Preparation of materials.
According to the design requirements, prepare the required materials, including polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber granules or PU granules, pigments, additives, fillers, etc. Pay attention to the quality and quantity of materials to ensure that they meet the design requirements and construction plan.
Third, the foundation is waterproof.
In order to prevent moisture from penetrating into the inside of the foundation, resulting in problems such as blistering and delamination of the plastic runway, it is necessary to paint waterproof materials on the surface of the foundation. Make sure that the waterproof layer is evenly applied and that nothing is missed.
Fourth, lay the primer.
According to the design requirements, the primer is laid on the surface of the foundation. The function of the primer is to increase the adhesion between the plastic runway and the foundation, and at the same time play the role of buffering. When laying, ensure that the primer is uniform and flat, and there are no bubbles and falling off.
Fifth, lay the reinforcing layer.
On top of the primer, a reinforcing layer is laid. The reinforcing layer is composed of EPDM rubber particles or PU particles, pigments, additives and other materials, and its function is to increase the hardness and anti-wear performance of the plastic runway. When laying the reinforcing layer, it is necessary to ensure that the material is evenly laid, and there is no leakage and accumulation.
Sixth, lay the surface layer.
On top of the reinforcing layer, the surface layer is laid. The top layer is composed of polyurethane paint and EPDM rubber particles, which have the characteristics of bright colors and UV resistance. When laying the surface layer, it is necessary to ensure that the coating is uniform and flat, and there is no obvious color difference and bubbles.
7. Scribing and patterning.
On top of the surface layer, mark the runway line, pattern and other signs according to the design requirements. Use a special scribing paint to ensure clear lines, bright colors, and no visible burrs and blurring.
8. Maintenance and maintenance.
After the construction of the plastic runway is completed, it needs to be maintained and maintained. Heavy pressure and heavy friction should be avoided during maintenance to avoid damage. In the process of use, regular maintenance and maintenance should be carried out to keep the plastic runway in good condition.
The above is a detailed introduction to the construction process of the plastic runway. In the construction process, it is necessary to operate in strict accordance with the process flow to ensure that the construction quality meets the requirements. At the same time, it is necessary to strengthen quality control and safety management to prevent safety accidents and quality problems. Through scientific and reasonable construction and maintenance, the plastic track can provide a good sports environment for athletes and effectively improve sports performance.
