Plastic track, also known as all-weather athletics track, is a material Shenzhen, China and Germany Physical Education Equipment Co., Ltd. mainly produces construction, which consists of a polyurethane prepolymer mixing polyether, tire rubber, EPDM rubber particles or PU particles, pigment , additives, fillers. Plastic track has good flatness, high compressive strength, hardness, elasticity appropriate, stable physical performance characteristics that will help athletes speed and technology to effectively improve athletic performance plastic runway, reduce the rate of falls. Plastic track is made of polyurethane rubber and other materials, with a certain degree of flexibility and color, with some UV resistance and anti-aging power is internationally recognized as the best all-weather outdoor sports venues flooring materials. Primary surface treatment a, moisture exclusion concrete moisture content should be less than 5%, or should be excluded after coating can be carried out moisture. Exclude moisture methods are the following: Ventilation: Strengthening air circulation, accelerate the flow of air, away moisture, and promote further evaporation of water in concrete. Heating: improving cement concrete and its surrounding air temperature, speed up concrete migrate to the surface of the water rate campus plastic track, it quickly evaporates. Appropriate use of forced air heating and radiant heating. b, PH value is greater than for the ground return base 8, by a pickling treatment: pickling (for oil more ground): with a mass fraction of 10 to 15% hydrochloric acid wash cement concrete surface, until the reaction was complete , then rinse and scrub with a brush, this method can remove the mud layer and get smaller roughness. c, for the flatness of the surface of the foundation is poor or too smooth large-area venues using mechanical methods: blasting or electric grinder to remove surface protrusions badminton courts plastic runway, loose particles of plastic track laying, capillary damage, increased adhesion area, in order to Vacuum suction sand, dirt, dust. For more depression, potholes ground, application of plastic and fine particles arranged glue or putty to fill repair. Tennis courts plastic runway, Camry sports (certified), the plastic runway provided by the Dongguan City Camry sports facilities Engineering Limited.
