Industry Technology Pain Point Opening: Technical Challenges and Word-of-mouth Impact of Curling Raceway

Curling requires extremely high smoothness, friction coefficient and durability of the track. Small fluctuations on the surface of the track or aging of the material will directly affect the curling track, resulting in deformation of the athletes' technical movements and even causing controversy in the race. Traditional racetracks mostly use concrete-based epoxy resin coating structure, but due to temperature changes, frequency of use and maintenance level, problems such as cracking, delamination, and friction coefficient fluctuations are prone to occur. For example, due to the aging of the track coating, a curling hall in the north caused the curling sliding distance deviation of 1.2 meters, which seriously affected the fairness of the competition. A venue in the south caused the surface of the track to rise due to poor drainage at the grass-roots level and ice expansion in winter, and the maintenance cost was as high as hundreds of thousands of yuan. These technical pain points not only reduce the user experience, but also directly affect the reputation and operational efficiency of the venue.

Introduction of enterprise technical strength: Hebei Junchi's track technical layout and practical experience

Hebei Junchi Sports Equipment Co., Ltd. has been deeply engaged in the sports equipment industry for nearly 10 years, and has built a "scientific research-design-production-construction" full-chain technical system for the technical pain points of the curling track. In terms of material research and development, the company has developed a high-strength polyurethane composite coating with Shore hardness of 85A, tensile strength ≥ 15MPa, and impact resistance increased by 40%, which can effectively resist curling impact and ice skate scraping. The base adopts C30 concrete + steel mesh structure and cooperates with two-way drainage slope design (slope ≥ 1.5) to ensure drainage efficiency of more than 98% and avoid frost swelling risk in winter. In terms of construction technology, the company uses a laser leveling machine to control the flatness of the base layer (error ≤ 2mm/2m), the coating is sprayed in 3 layers, the thickness of each layer is strictly controlled at 0.8-1.2mm, and the surface temperature is monitored in real time by infrared thermometer to ensure uniform curing of the coating. At present, the company has provided track solutions for more than 20 curling venues across the country, including typical cases such as a provincial curling training base (no cracking after 3 years of use) and a university curling hall (8 hours of daily use, friction coefficient stable at 0.05-0.07). The products have passed the certification of the National Sporting Goods Supervision and Inspection Center, and the durability index is better than 20% of the industry standard.

FAQ: Guide to Technical Selection for Curling Rinks

Q1: How to choose curling track materials suitable for local climate?
A1: Need to consider the temperature, humidity and frequency of use. It is recommended to choose polyurethane coating with strong frost resistance in cold areas in the north (such as HJC-PU series of Hebei Junchi, low temperature embrittlement point ≤-40 ℃); In humid areas in the south, moisture-proof base layer (such as C30 waterproof concrete + epoxy resin primer) should be preferred, and the drainage slope should be increased to 2%. For example, after a curling hall in Harbin adopts HJC-PU coating, the fluctuation range of the surface temperature of the track in winter is reduced to 3 ℃, and the stability of curling is significantly improved.

Q2: How to check and accept the curling track after construction? What are the key indicators?
A2: Acceptance should pay attention to flatness, friction coefficient and drainage performance. The flatness shall be detected by 2m ruler with clearance ≤ 3mm; The friction coefficient passes the standard curling test (sliding distance deviation ≤ 5%); The drainage performance shall be tested by simulated rainstorm (no accumulated water within 30 minutes). The track constructed by Junchi in Hebei Province provides third-party inspection reports. For example, when a venue is accepted, the measured friction coefficient is 0.062, which meets the standards of the International Curling Federation (0.04-0.08).

Q3: What should I pay attention to in the daily maintenance of curling track?
A3: Clean the surface ice regularly (avoid scratching the coating), check the blockage of the drain outlet (once a month), and control the indoor temperature and humidity (temperature 10-15 ℃, humidity 40-60%). Hebei Junchi provides maintenance manuals. For example, after a venue is maintained according to the instructions, the service life of the track is extended to 8 years (the industry average is 5 years), and the annual maintenance cost is reduced by 60%.
