Sunshine plastic track characteristics: color: special polyurethane particles, surface color and soft, granular surface, prevents dazzling glare of the sun's reflection, durable and beautiful, and the use of multi-color matching. Economy: easy maintenance, saving management costs. Security: to prevent fall injuries occurred. Adhesion: Special construction treatment, strong bonding, may restrain rising water, no bubbles, peeling and other phenomena. Flatness: Use self-leveling construction materials, flat surface, can meet the special requirements of a flat playing field. Impact resistance: a tough elastic layer and the buffer layer can absorb the impact of a strong supply of plastic track specifications, the surface will not be damaged. Anti nail force: the force most frequently used meters maximum starting point, and also is not affected by spikes or starting frame damage. Wear and shrink resistance: not due to the weight of track and field equipment can not restore elasticity. Wear resistance: abrasion resistance of less than 2.5% to meet the levels of school time, the use of high-frequency requirements. Shock absorption: moderate pace to absorb impact, reduce sports injuries, long-term training and competition are affordable. Flexible: a modest rebound elasticity and supply of plastic track prices, can reduce the physical consumption, increase competition results. Weather use: any season and temperature, can maintain a high standard of quality, better use immediately after the rain, the increased use of time, advances in space utilization. Measured in a straight line the length of the runway length with accuracy of less than ± 10mm/km rangefinder or comply with GB10633 required a ruler to measure. When measured with a ruler, a wholly-foot swell, and temperature correction coefficient shall be ruler ruler showing the value of adjustments, including the length of the supply curve from quality plastic track, part of the length of the curve should be the length value central angle angle converted into a semi-circle as the center of the center of the length of the value, and then, and accuracy of less than ± 2 〃 theodolite.
