First, the characteristics of breathable plastic runway:
1, non-foaming: its bottom layer is a combination of single liquid PU and elastic rubber particles, and it is an environmentally friendly product with breathable function. At high temperature, the steam generated by the foundation will be quickly emitted. The steam pressure will not accumulate, so it will not bubble, and it meets the professional requirements and has good elasticity.
2. The surface layer is made of EPDM rubber particles, which has strong ultraviolet resistance. Practice has proved that it does not fade and has strong wear resistance.
3. No particles fall. EPDM (ethylene propylene diene monomer) rubber particles on the surface layer are mixed and stirred with polyurethane slurry and prepolymer, and then mechanically sprayed for construction.
4、? Excellent weather resistance, not easy to age.
5, the elasticity is stable, there is no difference in elasticity throughout the year, and it will not be hard in winter and soft in summer.
6. Strong power rotation and shock absorption, emphasizing the comfort and safety of athletes, help athletes to play or improve their performance.
7. Emphasize the overall performance of the runway and adapt to various events and long-term competition training.
8, drawing lines are not easy to paint off, the color is bright, does not fade, and the wear resistance is better.
9. The flatness reaches the IAAF standard and the drainage is good. There is no need to stop the game on a rainy day, and the game can be played immediately after the heavy rain, and there will be no water accumulation.
Second, the characteristics of EPDM plastic runway:
1, sun resistance and corrosion resistance: it can be used all day, will not fade due to pollution such as ultraviolet rays and acid rain, and can maintain its advanced quality for a long time.
2. Flexible collocation of multiple colors: multiple colors, soft colors, beautiful and durable, and multi-color collocation can be adopted.
3. Strong wear resistance: the wear resistance is less than 2.5%, which can meet the needs of long-term and high-frequency use in schools at all levels.
4. Anti-damage: At the starting point of 100 meters with the greatest stress and the most frequent use, it will not be damaged by spikes or starting frames.
5. Simple maintenance: easy to maintain and save management costs.
Third, the characteristics of the mixed plastic runway:
1. All-weather use: it can maintain a high quality level in any season and temperature difference, and can be used immediately after rain, increasing the utilization time and improving the utilization rate of the site.
2. Elasticity: It has moderate elasticity and toughness, which can reduce physical consumption and improve competition performance.
3, impact resistance: moderate absorption of foot impact, reduce sports injuries, long-term practice and competition are suitable.
4. Weather resistance: it will not fade, powder and soften due to the pollution of ultraviolet rays, ozone and acid rain, and can keep its bright colors for a long time.
5. Wear resistance: the wear resistance is less than 2.5%, which meets the needs of long-term and high-frequency use in schools at all levels.
6, compression: will not be unable to restore elasticity because of the weight of track and field equipment.
7. Nail resistance: it will not be damaged by nail shoes or starting frame at the starting point of 100 meters with the greatest stress and the most frequent use.
8. Impact resistance: it has a strong elastic layer and a buffer layer, which can absorb strong impact and the surface will not be damaged.
9. Smoothness: Self-leveling materials for construction have a flat surface, which can meet the requirements of a particularly flat playing field.
10, adhesion: special construction treatment, strong adhesion, can inhibit moisture rise, no foaming, peeling and other phenomena.
1 1. Safety: it can prevent sports injury caused by falling.
12, economy: easy to maintain and save management costs.
13, color: special high-elastic EPDM and PU particles, soft surface color, granular surface to prevent glare reflection, beautiful and durable, and can be used with multi-colors.
Characteristics of prefabricated plastic track: The biomechanical requirements of athletes are fully considered in the design process; the three-dimensional mesh internal structure makes the track have excellent elasticity, strength, toughness and shock absorption effect, effectively reducing muscle fatigue and minor injuries of athletes.
The molded product consists of an upper layer and a lower layer with concave-convex patterns. The upper layer is colored composite rubber, which has long-term ultraviolet resistance and changeable climatic and meteorological conditions. The concave-convex pattern surface design has excellent anti-slip, anti-nail, anti-wear and anti-reflection effects.
The lower layer is made of black composite elastic material, and the bottom layer is designed with concave-convex patterns. At the same time, the anchoring density between the runway material and the base surface is maximized, and the rebound force generated by the closed air in the hole at the moment of impact is transmitted to the athletes, thus effectively reducing the impact during sports.
1, no rubber particles, no threshing, very suitable for frequent use.
2, good shock absorption effect and excellent rebound performance; Good adhesion and strong puncture resistance.
3. Good anti-slip and wear resistance, even in rainy days.
4, with extraordinary anti-aging, anti-ultraviolet ability, durable and stable color matte surface, no reflection, no glare.
5. Prefabricated and easy to install.
6, all-weather use, long service life; Simple maintenance and low maintenance cost.
7. Good flame retardancy, insulation and sound insulation, and high fire safety.
8, non-toxic, harmless, in line with environmental requirements.
Extended data
Generally speaking, track and field usually refers to the track and field of schools and professional stadiums at all levels. There are standard tracks and non-standard tracks. The standard track is 400 meters in circumference and 36.5 meters in radius (there are also 36 meters and 37.898 meters).
Non-standard runway refers to properly adjusting the radius and perimeter of the playground according to the shape and size of the playground land area. Common perimeters are 200m and 300m.
According to the construction structure and materials, plastic runways can be divided into prefabricated plastic runways, all-plastic plastic runways, mixed plastic runways, composite plastic runways, breathable plastic runways and EPDM plastic runways.
Precast plastic track and all-plastic track are common types of professional track and field venues because of their unparalleled excellent performance, but their high prices are beyond the reach of ordinary schools.
The performance of mixed plastic runway and composite plastic runway is between full plastic runway and breathable runway, and the price is slightly lower than that of full plastic runway, but it is also much higher than that of breathable runway, which requires higher foundation.
The performance of the breathable plastic runway can completely reach the indexes of GB/ 14833-93, and it is breathable and permeable, with short construction period, easy maintenance and reconstruction, and the highest cost performance. It is also the first choice for schools and colleges.
EPDM plastic runways are mainly used for non-standard runways such as primary schools or kindergartens.
