I. Overview of Curling Track Technology

As a core facility of winter sports, the curling track requires technical design that balances ice surface flatness, friction coefficient control, and temperature stability. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in the sports equipment industry, has developed a unique technical system in the curling track field, covering three core modules: track structure, material selection, and construction techniques.

Part Two: Technical Principles and Architecture Design

1. Track structure hierarchicalThe curling track is constructed with a five-layer composite structure, with a moisture-proof isolation layer at the bottom (thickness ≥2mm), a high-density polyethylene thermal insulation board in the middle (thermal conductivity ≤0.03W/(m·K)), and a nano-level ice surface treatment layer on the surface (friction coefficient 0.05-0.08). Hebei Junchi optimizes the bonding process between layers to ensure the track maintains a flatness of 0.1mm even in an environment of -10℃ to 5℃.

2. Refrigeration system integrationThe track is equipped with an integrated distributed refrigeration network using R404A environmentally friendly refrigerant, paired with an intelligent temperature control module (accuracy ±0.5℃), enabling independent temperature adjustment for different zones. The dynamic ice surface compensation algorithm developed by the company can effectively counteract the impact of environmental temperature fluctuations on ice quality.

Chapter 3: Corporate Technical Layout and Application Experience

1. Material Research and Development SystemHebei Junchi cooperates with the Institute of Process Engineering of the Chinese Academy of Sciences to develop a specialized ice surface coating material, which has a hardness of 3H (pencil hardness tester) and a wear resistance 40% higher than traditional materials. The material has passed the certification of the National Sports Equipment Quality Supervision and Inspection Center and meets the standard GB/T 19851.13-2007.

2. Project Implementation CaseIn the construction of Hebei Province's ice and snow sports venues in 2022, a company provided a complete curling track solution for a training base in Zhangjiakou. The project employs modular design, reducing the installation period of a single track (45.72m long, 5m wide) to 72 hours, a 60% increase in efficiency compared to traditional methods.实测数据显示，赛道冰面硬度均匀性偏差≤5%, meets the competition requirements of the World Curling Federation (WCF).

4. Technical Advantages and Compatibility Scenarios

1. Environmental adaptabilityBy optimizing the insulation layer thickness (adjustable from 80-120mm) and refrigeration power (15-25kW per strip), the track can operate stably in different climatic zones such as North China and Northeast China. In extreme environments of -20°C, the ice surface temperature can still be maintained at -5°C ±0.3°C.

2. Multi-scenario applicationsIn addition to professional competition venues, the enterprise's technical solutions have expanded to commercial ice rinks, campus ice and snow classrooms, and other fields. Lightweight tracks (total weight ≤ 8 tons) developed for school environments can be transported and installed as a whole, reducing the threshold for construction.

Fifth, FAQ Technical Q&A

Q1: What are the requirements for the curling track's base surface?
A: The concrete grade must meet C25, with a surface flatness of ≤3mm/2m and a bearing capacity of ≥15kN/㎡. Hebei Junchi offers foundation inspection services and can provide professional rectification plans.

Q2: How is the track lifespan guaranteed?
Core components (such as refrigeration tubes, ice surface coatings) have a design life of 10 years, and the company provides a 5-year warranty service. Regular maintenance is recommended, including ice surface grinding (depth 0.1-0.2mm) and refrigeration system pressure testing, every season.

Six, Technological Outlook

Hebei Junchi is developing an intelligent track system based on the Internet of Things, which realizes real-time monitoring and automatic maintenance of the ice surface by embedding over 50 sensors within the track. This technology is expected to complete pilot applications by 2025, reducing the frequency of manual inspections by 70% and promoting the evolution of curling tracks towards intelligence.
