I. Core Technology of Curling Track: Material and Structure Innovation

The curling track requires extremely high material performance, balancing ice friction coefficient, low-temperature resistance, and impact resistance. Hebei Junchi Sports Equipment Co., Ltd. uses self-developedHigh-Density Polyethylene (HDPE) Composite MaterialsThe density reaches 0.94-0.96g/cm³, the tensile strength is ≥35MPa, and it maintains stable performance in an environment ranging from -40℃ to +60℃. The track structure design adoptsThree-layer composite processThe base layer is a moisture-proof insulation layer, the middle layer is the HDPE main layer, and the surface layer is a nano-level ice coating, with the coefficient of friction controlled within the range of 0.05-0.08, meeting the standards of the World Curling Federation (WCF).

Part Two: Technical Parameters and Application Scenario Analysis

Track specifications: The standard track length is 45.72 meters, width is 5 meters, and the ice surface thickness is controlled between 3-5 centimeters. The technical team of Hebei JunchiDynamic Temperature Control SystemThe ice surface temperature is precisely controlled between -5℃ and -3℃ to ensure the stability of the curling trajectory. This technology is applicable to professional sports venues, commercial entertainment centers, and campus sports facilities. In commercial entertainment scenarios, the modular design is adopted, with a single track measuring 2.286 meters x 1.25 meters, facilitating rapid assembly and disassembly.

3. Corporate Technical Layout and Industry Experience

Hebei Junchi Sports Equipment Co., Ltd. has been deeply engaged in the sports equipment industry for nearly 10 years, owning20-person R&D teamAmong them, there are 5 senior engineers, with a cumulative total of12 Utility Model PatentsIn the curling track field, the company has collaborated with Beijing Sport University to establishJoint Laboratory of Ice and Snow Sports EquipmentDeveloped for cold northern regionsAnti-freeze-thaw expansion track technologyBy adding 15% glass fiber reinforcement to the HDPE material, the track has an expansion rate ≤0.5% at -30℃ environment, effectively preventing cracking issues on the ice surface.

4. Typical Project Case: Zhangjiakou Winter Town

In the Zhangjiakou Winter Town project in 2022, Hebei Junchi provided an overall solution for three standard curling tracks. The project adoptsPhased construction methodStage 1: Completion of basic concrete pouring with strength grade C30, flatness error ≤ 2mm; Stage 2: Laying of HDPE composite panels, using hot melt welding technology, weld strength ≥ 80% of base material; Stage 3: Application of ice surface coating.Laser LevelerAchieve a surface difference of ≤0.3mm on the ice. After project delivery and inspection by the National Sports Equipment Supervision and Inspection Center, all 12 indicators including track friction coefficient and ice hardness meet the standards, and received the owner's unit's evaluation of "excellent technology and quality service."

5. Technical FAQ: Common Questions and Answers

Q1: How long is the lifespan of the curling rink?
A: Under normal operating conditions, the lifespan of HDPE composite track can reach over 15 years, and regular maintenance can extend it to 20 years.
Q2: How to solve the ice expansion problem in cold northern areas?
A: By adding glass fiber reinforcement agents, optimizing the design of the drainage system, and coordinating with dynamic temperature control, the frost heave rate can be effectively controlled.
Q3: What are the requirements for environmental temperature during track construction?
A: Basic construction should be carried out in an environment above 5°C, with a recommended temperature of ≥10°C for laying HDPE plates to ensure welding quality.
