The stadium track material has a great impact on the athletes, so in the construction of the stadium track to choose good materials! Following Shanghai jiehao xiaobian look at a variety of stadium materials.
Above all, the choice of playground material should be based on the utility of playground, adjust measures to local conditions even. The venues for major sporting events should comply with the requirements of the competition rules, such as standard and on-site design
The plastic track material is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particle or PU particle, pigment, auxiliary agent and filler. The plastic track has good flatness, high compressive strength, appropriate hardness and elasticity, physical properties and other characteristics of stability, is conducive to the athletes' speed and technical play, not easy to fall injury. Plastic runway has a certain elasticity and color, with uv resistance and aging resistance, is internationally recognized as the better all-weather outdoor sports ground material. There are several kinds of plastic runway:
It is a double spray polyurethane runway. The basic layer is black environment-friendly rubber particles bonded by polyurethane resin, and the surface layer is colored EPDM rubber particles mixed with polyurethane and sprayed directly on the surface layer by SMG machinery.
The basic layer is black environment-friendly rubber particles bonded by polyurethane resin, and the surface layer is colored EPDM rubber particles cast in polyurethane resin.
(3) prefabricated type
It is a prefabricated coil track. Based on natural rubber and artificial rubber, mineral fillers, stabilizers and colors are mixed in the continuous calendering treatment in the factory, and formed by sulfur hardening at 280-300℃ with mechanical embossing and uniform double layer structure synthetic rubber.
PU and black rubber particles mixed into a certain proportion of the runway system. The material is transported to the site and mixed in a certain proportion. The catalyst is added to stir it evenly. The surface layer is vulcanized and formed at room temperature.
Sports track in gymnasium and school are mostly laid by EPDM sports ground system. EPDM sport ground system is composed of EPDM colored rubber layer and black rubber buffer layer on the surface. The test shows that it can fully improve the speed of sports and has a good cushioning effect on athletes' joints. There are many colors to match at will. It can be directly laid on the concrete foundation, and can save a lot of foundation cost compared with the traditional PU surface layer.
After reading the above stadium track material related information, is it true that everyone has a new understanding of the stadium track? If you want to know more about this area, please continue to pay attention to our website!
