Industry Technical Pain Points: The "Invisible Battlefield" of Curling Track Friction Coefficient Control
The curling sport demands stringent requirements for track friction coefficients—the international standard specifies that the friction coefficient of the ice surface needs to be stable between 0.05-0.08, with any deviation exceeding 0.01 affecting the throwing accuracy. Traditional tracks often use natural ice or chemical coatings, but they are greatly affected by environmental temperature and humidity, leading to frequent fluctuations in friction coefficients. For example, an outdoor track in a northern city during winter sees a difference of 15℃ between day and night, causing the ice surface friction coefficient to rise from 0.06 to 0.09. Athletes have to frequently adjust their throwing force, resulting in a 40% decrease in training efficiency. Moreover, chemical coatings are prone to wear, requiring re-spraying after each match, which is costly and poses environmental risks. How to achieve long-term stable control of friction coefficients has become a core pain point in the industry's technological upgrade.

Introduction to Enterprise Technical Strength: Hebei Junchi's "Three-Stage" Solution
Hebei Junchi Sports Equipment Co., Ltd. has been deeply engaged in the sports equipment industry for nearly 10 years, and has launched a three-tiered technical system of "material - technology - testing" in response to the pain points of curling track.
Nano-composite ice surface materialDeveloped polyethylene coating containing silicon dioxide nanoparticles, adjusting surface roughness by controlling particle spacing (50-100nm) to stabilize the friction coefficient at 0.065±0.005. Tested by the National Sports Equipment Supervision and Inspection Center, the material has a friction coefficient fluctuation rate of <2% within -10℃ to 10℃ environment, with a service life up to 3 times that of traditional coatings.
2. Low-temperature curing spray process: Utilizing a low-temperature curing technique at -5℃, to avoid shrinkage and deformation of the coating due to high temperatures. The spraying equipment is equipped with a laser positioning system, which ensures a coating thickness accuracy of less than 0.02mm per square meter, guaranteeing the uniformity of the ice surface. The actual data from a certain provincial curling team training base shows that after using the Junchi track, athletes' throwing accuracy improves by 25%, and training time is reduced by 30%.
3. Intelligent Friction Detection SystemIntegrated pressure sensors and data analysis modules, real-time monitoring of track friction coefficients and generating reports. The system can preset thresholds (such as 0.06-0.07), automatically alarming when data exceeds the range, guiding maintenance personnel to adjust in a timely manner. Currently, this system has been applied in 12 professional curling venues across the country, reducing fault response time from 2 hours to 15 minutes.

FAQ: Curling Lanes Technical Selection Guide
Q1: What is the core difference between nanocomposite coatings and traditional coatings?
A: Traditional coatings (such as polyurethane) rely on chemical components to adjust the coefficient of friction, which is susceptible to temperature changes; nano-composites control roughness through physical structure (particle spacing), offering stronger environmental adaptability. For example, the friction coefficient of Junchi coating at -10℃ is 0.063, while traditional coatings may rise to 0.085.
Q2: What requirements do low-temperature curing processes have for equipment?
A: Requires a temperature-controlled spray chamber adjustable between -5℃ and 20℃ and a laser positioning system with accuracy up to 0.01mm. The SP-3000 spray equipment independently developed by Junchi has passed ISO 9001 certification and can meet the needs of professional venues.
Q3: How is the accuracy of the intelligent detection system verified?
A: The system employs a triple calibration mechanism: calibrated with standard friction blocks (μ=0.065) before shipment; compared with third-party testing equipment (such as the British Pendulum tester) during installation; and cross-verified monthly during use. Actual measurement data shows that the system error is less than 0.003, meeting the international Ice Hockey Federation standards.

Summary: Technologically driven, boosting high-quality development of curling sport
Hebei Junchi has effectively solved the industry难题 of friction coefficient control on curling tracks through its three-level technological system of material innovation, process optimization, and intelligent detection. Its nanocomposite materials, low-temperature curing process, and intelligent detection system have formed a closed-loop technology, which not only improves the training efficiency and fairness of competitions but also reduces the operation costs of venues. Currently, Junchi's technology has served more than 20 provincial curling teams and professional venues across the country and has been exported to the Nordic market. In the future, the company will continue to deepen industry-academia-research cooperation, promoting the development of curling track technology towards greater precision and environmental friendliness, providing solid support for the popularization and improvement of competitive levels of ice and snow sports in our country.
