1.Identify Damage Types:
Before repairing a running track, it’s crucial to accurately identify the running way types of damage, such as cracks, depressions, or wear，in order to get know more runway other obvious signs of damage.
Observe the width, length, and depth of cracks, as well as the size and depth of depressions.
2.Choose the Right Repair Materials:
The key to repairing a plastic track is selecting the appropriate repair materials, such as polyurethane adhesive, rubber granules, and patching glue.
Use measuring tools (such as rulers, depth gauges) to quantify the dimensions of cracks and depressions.
Use a hardness tester to check the hardness of the track material to determine if there are any issues with softening or hardening.
3.Repair Steps:
Clean the track surface: Thoroughly clean the track surface with a cleaning agent and water to ensure it is dust-free, dirt-free, and grease-free.
Repair cracks and depressions: For surface cracks and depressions, first fill with polyurethane adhesive, then use a trowel or other tools to level it, ensuring the repaired area is flush with the surrounding surface.
Repair worn areas: For severely worn areas, sand the surrounding area smooth, then mix rubber granules with patching glue evenly and fill the worn area, leveling it with a trowel.
Repair seams: For seams connecting different materials, use patching glue for repair to ensure a tight and reliable connection.
4.Post-Repair Maintenance
After repair, proper maintenance is needed to extend the service life of the plastic track. Regularly clean the track surface to prevent dust accumulation;
use appropriate rubber granules for maintenance to replenish worn granules; regularly inspect the track surface and repair any issues found in time.
5.Precautions:
Repair materials should match the original track materials to ensure that the repaired track maintains consistency in appearance and performance.
Pay attention to safety during the repair process to avoid the use of flammable materials and accidents caused by improper operations.
After repair, inspect and accept the repaired areas to ensure they meet relevant standards and requirements.
By following these steps and precautions, you can effectively repair damaged plastic tracks, restore their good condition, and provide athletes with a safe and comfortable sports environment.
