I. Technical Background and Industry Positioning

Hebei Junchi Sports Equipment Co., Ltd. has been deeply involved in the sports equipment industry for nearly 10 years, leveraging the location advantage of Haixing County, Cangzhou City, to form a complete industrial chain integrating R&D, design, production, sales, and services. The company's curling track technology is centered around "material innovation + structural optimization," meeting international event standards and daily training needs through self-developed composite track materials and precise construction techniques. Its products have covered multiple provincial sports venues across the country and participated in the construction of tracks for many national events, with its technical maturity and stability widely recognized by the industry.

II. Core Technology Analysis: Material and Structure Innovation

1. Track base material formulaComposite with high-density polyethylene (HDPE) and nano-grade additives, density controlled at 0.94-0.96g/cm³, impact resistance increased by 30%, and low-temperature performance up to -40℃ without cracking. The base material surface is treated with special polishing, with the friction coefficient stable between 0.05-0.08, meeting the standards of the World Curling Federation (WCF).

2. Hierarchical structure designThe track consists of three parts: the base layer, the buffer layer, and the contact layer. The base layer is made of 15mm thick high-strength steel plate with a load-bearing capacity of ≥500kg/m²; the buffer layer is a 5mm thick rubber shock-absorbing pad with an impact absorption rate of ≥85%; the contact layer is a 2mm thick HDPE panel with a surface flatness error of ≤0.2mm, ensuring precise and controllable sliding trajectory of the curling stones.

3. Modular assembly technologyThe single track section measures 3m x 1.5m, featuring a clip-on connection design, with a joint gap error of ≤0.1mm. Installation efficiency is increased by 50% compared to traditional methods. Modules are equipped with embedded sensors for real-time monitoring of temperature and humidity, with data feedback to the central control system for dynamic adjustment of environmental parameters.

Section 3: Practical Case: Construction Project of a Provincial Curling Rink Track

1. Project BackgroundThe curling club requires the construction of a 4-lane curling rink meeting WCF standards, with a total area of approximately 1200㎡. The track surface friction coefficient uniformity should be ≤5%, and the service life should be ≥10 years.

2. Technical Implementation：

STEP1Site foundation treatment. Leveling of concrete subgrade with laser levelling instrument, controlling flatness error within ±2mm, and laying waterproof membrane to prevent groundwater penetration.

STEP2Track module installation. Assemble 3m×1.5m modules according to the design drawings, use a level to calibrate the height difference of each module's corners ≤0.5mm, and ensure the overall flatness error ≤1mm after assembly.

STEP3Environmental control system deployment. Install temperature and humidity sensors and fresh air systems around the track, regulate indoor temperature (10-15℃) and humidity (40-60%) through PLC controllers, ensuring stable track performance.

3. Effect verificationAfter project delivery, the track surface friction coefficient uniformity was tested by a third-party testing institution and reached 3.2%, with an impact resistance of 45J/m², fully meeting the WCF certification requirements. The venue has hosted 3 provincial curling competitions, with a track usage frequency of 200 events/year, without any structural damage or performance degradation.

4. Technical Advantages and Industry Applications

1. Performance stabilityThrough material formula optimization and structural layered design, the track maintains stable performance in an environment ranging from -20℃ to 40℃, adapting to the complex climate of severe cold in northern China's winters and humid summers in the south.

2. Construction EfficiencyModular assembly technology shortens the traditional 15-day construction period to 7 days, reduces labor costs by 40%, and supports local module replacement, significantly enhancing maintenance convenience.

3. Scenario adaptabilityThe technical solution can flexibly adjust track size and friction coefficient, suitable for both professional sports venues and the training needs of non-professional sites such as schools and communities. Currently, the company has provided customized track solutions for over 20 universities and 30 community sports centers.

V. Future Technology Layout

Hebei Junchi Sports Equipment Co., Ltd. will continue to invest in R&D resources, focusing on the following directions:

1. Intelligent upgradeIntegrate more sensors in the track module to achieve real-time collection and analysis of data such as gliding speed and trajectory deviation, providing scientific evidence for athletes' training.

2. Environmental protection material applicationDevelop degradable base materials to replace traditional HDPE, reduce the carbon emissions throughout the entire life cycle of the track, and respond to the national "dual carbon" strategic goal.

3. International Standard ConvergenceCollaborating with the WCF Technical Committee, participating in the formulation of the next-generation curling track standards, and promoting Chinese technology to the international market.
