Plastic track is a common ground material in modern track and field stadiums, which not only provides a display platform for athletes to compete, but also an important symbol to measure the quality of a field. With the continuous coverage of major sports venues by plastic runways, the competition in market demand has intensified, and there have been many cases of shoddy, inferior and toxic plastic runways, which have brought great hidden dangers to the safety and quality of sports venues. As a non-professional, how to distinguish the worst of the plastic runway?
Observe the appearance
1.Color consistency: a good runway has bright and uniform color, and there is no color difference. If you find different shades of color, it may be because the raw material ratio is unreasonable or there is a problem with the production process.
2.No bubbles: The plastic runway is a polymer material, and the surface should be smooth and free of bubbles. If there are bubbling and depressions, it means that the compressive strength of the material is not enough, which may affect the use effect and life.
3.No cracks: Inspect the runway surface for visible cracks, especially at the joints. Cracks may cause problems such as deformation and cracking of the runway during use.
Smell the smell
A good quality plastic runway should have a light plastic smell without any pungent or unpleasant odors. If you smell pungent or musty, it is likely that the quality of the material is not up to par and there is a safety hazard.
Hardness is tested
Track hardness has a direct impact on athletes' sports safety and comfort. It can be measured by professional hardness testing equipment, and the hardness is generally required to be between 85-90. In addition, you can also touch the runway surface with your hands, and the plastic runway surface with moderate hardness should be smooth and elastic.
Abrasion resistance test
Long-term use will lead to runway wear, and abrasion resistance is an important indicator to measure the quality of rubber runway. It can be detected by scratch testing, where a metal block under a certain pressure is placed on the surface of the runway to observe the depth of the scratch. Rubber runways with good abrasion resistance have shallow scratches, and vice versa is poor.
Slip resistance
The anti-slip performance of the plastic track is related to the safety factor of athletes during sports. It can be detected by the slippery test, where water is sprayed on the surface of the track to observe the slippery conditions of the athlete while running. The plastic track with good anti-slip performance is not easy to slip and can effectively ensure the safety of athletes.
Environmental performance
A high-quality runway should have good environmental performance, contain no harmful substances, and be harmless to the environment and human health. You can check the relevant reports of raw materials and runway-related test and certification reports to understand whether they meet the requirements of national environmental protection standards.
