Zhixin Series Baimisheng Prefabricated Rubber Track Membrane: Performance Revolution of Professional Sports Venues
Publish Time: 2025-05-06
Under the background of the coordinated development of national fitness and competitive sports, Zhixin Series Baimisheng Prefabricated Rubber Track Membrane has redefined the construction standards of track and field venues with the dual-core drive of "professional performance + comprehensive efficiency". The product has passed the triple authoritative endorsement of the World Athletics Federation, the China Athletics Association and the new national standard GB 36246-2018, and has achieved breakthroughs in the three dimensions of weather resistance, environmental protection and sports protection, becoming the preferred solution for upgrading and renovation of universities, middle schools and professional sports venues.Its core performance advantage comes from the deep integration of material technology and structural design. The scientific ratio of EPDM rubber and SBR recycled rubber is adopted, and the molecular chain cross-linking enhancement technology is combined to make the track membrane have a folding resistance of 150,000 times without cracks, which is 3 times higher than that of traditional products. In the extreme climate test in Sanya, Hainan, after 3 years of direct ultraviolet radiation (8000MJ/m² cumulatively), the surface color retention rate is still 92%, and the anti-aging performance is certified by ASTM G154 standard. Its anti-UV layer uses nano-level zinc oxide dispersion technology to increase the reflectivity to 85%, effectively reducing the surface temperature of the venue by 10-15℃, solving the problem of heat stress in summer sports.In terms of sports protection performance, the Zhixin series has built a three-level buffer system. The bottom honeycomb structure is designed with a thickness of 6mm to achieve 35% energy feedback in the vertical direction, and with the 2mm elastic particle layer on the surface, the athlete's landing impact force dispersion efficiency reaches 78%. According to the laboratory test of Beijing Sports University, the runway membrane can reduce the fatigue of the athlete's quadriceps by 22% and the risk of Achilles tendon injury by 40%. In the spike anti-puncture test, its 1.8mm thickened bottom membrane can withstand a puncture force of 500N without damage, meeting the IAAF Class 2 event standard of the International Association of Athletics Federations.The innovation of the drainage system is another highlight of this product. The bionic lotus leaf hydrophobic structure is adopted, and the surface contact angle reaches 152°. Combined with the bottom diversion groove design, the depth of water accumulation in the field is controlled within 3mm in heavy rain weather (rain intensity of 50mm/h), and the drainage efficiency is improved by 60% compared with the traditional runway. In the application case of a middle school in Guangzhou, the renovated runway can still be used normally for 12 hours a day during the rainy season, and the utilization rate of the field is increased by 300%.In terms of environmental protection performance, the Zhixin series realizes green management and control throughout the life cycle. The production process uses water-based adhesives instead of solvent-based glues, and the VOCs emission is less than 10g/m², which meets the requirements of EU REACH regulations. Its recyclability rate reaches 95%, and the old materials can be remade into EPDM particles through cracking technology to form a closed-loop cycle. According to SGS testing, the heavy metal dissolution of the product is less than 0.5mg/kg, and phthalates are not detected, which meets the safety standards of children's activity venues.In terms of construction efficiency and cost control, the prefabricated membrane shows significant advantages. The single roll specification is 1.22m×20m. Through hot-melt welding technology, the construction period of a 2,000㎡ site can be shortened from 15 days of traditional technology to 7 days, and the labor cost is reduced by 40%. Its tensile strength reaches 4.5MPa, and its elongation at break is 320%. It can adapt to extreme temperature differences from -40℃ to 70℃, and the later maintenance cost is reduced by 65% compared with the breathable runway.From professional events to campus sports, Zhixin series baimisheng prefabricated rubber track membrane is promoting the construction and upgrading of sports venues with technological innovation. It not only solves the pain points of traditional runways such as easy aging, poor drainage, and substandard environmental protection, but also through standardized module design, primary and secondary schools can also have professional-grade sports venues at low cost. With the deepening implementation of the "sports and education integration" policy, this type of high-performance prefabricated runway membrane will surely play a greater role in the construction of national fitness infrastructure.
