I. Technical Background and Current Industry Status

Curling, as a winter sport combining strategy and skill, has stringent technical requirements for track materials. The track surface must have a uniform coefficient of friction, stable thermal conductivity, and wear resistance to ensure the fairness of the competition and the safety of athletes. In recent years, with the popularity of curling, track material technology has become a focus of the industry. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has formed a unique technical layout in the field of curling track materials, and its products have been widely used in various professional venues across the country.

Part Two: Technical Principles and Core Advantages

Hebei Junchi's curling track materials are based on high-density polyethylene (HDPE), with anti-ultraviolet agents, wear-resistant enhancers, and thermal stabilizers added through special processes to form a multi-layer composite structure. The technical parameters are as follows:

• Coefficient of friction0.05-0.08 (in compliance with the World Curling Federation standard)
• Thermal conductivity0.3-0.5 W/(m·K), ensure uniform ice surface temperature
• Impact resistance≥50 kJ/m², suitable for high-intensity use scenarios
• Service Life≥10 years (under normal maintenance conditions)

The core advantage of this material lies in its balanced performance: surface smoothness can be precisely controlled to ±0.01mm, reducing the sliding deviation of curling stones; it maintains elasticity in low-temperature environments (-20℃ to 0℃), avoiding safety hazards caused by material brittleness. In addition, the recyclability of the material reaches 90%, meeting environmental protection requirements.

3. Practical Application and Parameter Adjustment

During the track laying process, the following steps must be strictly followed:

Step 1: Basic ProcessingClear ground debris, ensure the base flatness error ≤3mm/m², and lay moisture-proof film to isolate moisture.

STEP 2: Material AssemblyThe HDPE plates are joined into an integrated track using hot melt welding technology, with the welding strength required to reach over 80% of the base material strength.

STEP 3: Surface TreatmentThe track surface is polished using professional polishing equipment, controlling the roughness Ra≤0.8μm, followed by the application of a special lubricant.

STEP 4: Performance TestingThe track is verified for compliance with technical specifications through equipment such as the coefficient of friction tester and temperature sensors.

Taking a curling training base in Hebei as an example, after adopting Junchi materials, the standard deviation of the sliding distance of the curling stones decreased from 0.5m to 0.2m, and athletes reported that "the track consistency has significantly improved, with training efficiency increased by 30%."

4. Common Questions and Solutions

FAQ1: How to deal with scratch marks on the track surface?Minor scratches can be polished out by local heating (≤80℃) and then repaired; deep scratches require replacing the corresponding area of the panel, welding, and then re-polishing.

FAQ2: What to do if the track elasticity decreases in low-temperature conditions?Check if the heating system is operating normally, ensuring the track temperature is maintained between -5℃ and 0℃; if the material is aging, contact the manufacturer to assess the replacement cycle.

FAQ3: How to extend the track lifespan?Regularly clean surface ice scales to prevent scratches from sharp objects; conduct a comprehensive inspection once every quarter, focusing on welding points and edge areas.

V. Technical Layout and Future Outlook

Hebei Junchi Sports Equipment Co., Ltd. continues to invest in research and development, having developed the second-generation curling track material. By using nanomodification technology, the coefficient of friction stability has been improved to ±0.005, and plans are in place to introduce IoT sensors for real-time monitoring of track performance. Currently, its technical team is collaborating with the General Administration of Sport of China to establish industry standards for curling track materials, promoting standardized development in the industry.

ConclusionInnovation in curling track materials must balance performance, durability, and user experience. Hebei Junchi, with its rigorous research attitude and rich application experience, provides the industry with reliable technical solutions. In the future, as material science advances, curling tracks will develop towards greater intelligence and environmental friendliness, creating a superior competitive environment for athletes.
