Mixed plastic runway IAAF approved materials using hybrid structure, the surface layer of PU particles or EPDM weathering green color particles, the mother is a full PU blending portion of the rubber particles. Construction process is simple, in line with international competition standards, standard thickness of 13mm. Mixed plastic track features: all-weather use, any season and temperature, can maintain a high standard of quality, the rain can be used immediately, increasing the use of time and improve space utilization. Flexibility: having appropriate elasticity and rebound, can reduce physical consumption, enhance competition achievements. Impact: Moderate absorb foot impact, reduce injuries, long-term training and competition are appropriate. Weather resistance: not because of ultraviolet radiation, ozone, acid rain, pollution and bleaching powder or softened, and long-term to maintain their bright colors. Wear: wear resistance of less than 2.5%, to meet schools at all levels for a long time, high frequency of use needs. Compression resistance: not because of the weight of track and field equipment can not restore elasticity. Anti-nail forces: the maximum force most frequently used starting point by the meter, will not be spikes or starting frame damage. Impact resistance: a tough elastic layer and buffer layer can absorb the strong impact, the surface will not be damaged. Flatness: Use self-leveling construction material, flat surface, can meet the particular requirements of a flat playing field. Adhesive: special construction process, strong bonding, can suppress the water rises, no blistering, peeling phenomenon. Security: You can prevent sports injuries fall occurred. Economy: easy maintenance, saving management costs. Color: special highly elastic EPDM and PU granules, surface color and soft, granular surface, preventing reflection glare light, beautiful and durable, and multi-color matching. Laying Process Description (1) First check the flatness of the base layer, for leveling of uneven parts (such as cement concrete foundation for an acid). (2) primer laying: laying of foundation cleaned first before the end of plastic, ready for construction tools. a) in accordance with the process required to measure the position of the construction line, place construction lines. b) laying side starting from the site, according to the width of disposable plastic scraper site. c) even when the squeegee speed, timely show the bottom of the recess, the projection of the conduct glue or gelling. d) After a glue, for the audience to be checked to ensure that the surface of the rubber laid thickness. (3) surface plastic paving: try to shorten a) Squeegee every barrel interval glue, so that uniform gelation speed. b) always observe the thickness of the plastic surface. c) shave gel, in front of uncured rubber, sprinkle with red particles, wait until the fully cured, the excess rubber surface cleaned. d) spray, to ensure that particles do not fall off. (4) spray processing line plan: according to the current track and field facility standards to accurately measure the position of the processing line, and then stencilled with polyurethane paint.
