Nearly all stadiums have plastic tracks. What are the advantages of plastic tracks? The following content will answer this question for everyone, you can refer to it.
Since the first plastic track was used in the 1964 Tokyo Olympics, it has not only been used by modern sports centers in various countries, but even some universities, primary and secondary schools in industrialized countries have begun to have plastic tracks. . So, what are the advantages of plastic runways?
Some people once called the plastic track an "all-weather track" because this type of track can continue racing even in heavy rain. The advantages of plastic track include good physical properties, suitable hardness, good elasticity, high friction and low energy loss. According to statistics, if you run on a cinder track, you will lose about 24% of your energy, while if you run on a plastic track, you will only lose 3-6%. Taking the 100-meter run as an example, athletes can shorten the entire distance from 53 steps to 52 steps, and the performance will increase by about 0.2 to 0.3 seconds. Its disadvantages are high cost and short life, and it needs to be updated every 10 years or so.
Plastic runway is also called tower runway or synthetic runway. According to records, the original birth of the plastic track was due to accidental reasons. At that time, industrial waste was difficult to process. Later, some people slightly processed it and made it into carpets for entertainment venues and materials for basketball, volleyball courts, and track and field tracks. The effect was very good, and it was gradually adopted by the track and field industry. With the development of science and the improvement of technology, the production process of plastic track has become very mature.
The plastic track needs a solid base, which is usually paved with asphalt, and then poured into a liquid synthetic material composed of polymer compounds and catalysts. Its thickness is generally 12-13 mm, and the track and field venue is thickened to 20 mm, and finally sprinkle with fine rubber particles. In addition, it can also penetrate different colorants into synthetic materials according to different requirements, usually crimson, which complements the football field turf, making people visually good and energetic.
