Technical Background and Industry Position

Hebei Junchi Sports Equipment Co., Ltd. is located in Haixing County, Cangzhou City, Hebei Province. Leveraging its advantageous location near the Jinsan Expressway and the coast of the Bohai Sea, the company has formed a complete industrial chain integrating research, design, production, and sales. With a deep focus on the sports equipment industry for nearly 10 years, its curling track products are renowned for their "high precision, wear resistance, and low-temperature resistance" characteristics. They have continuously passed the certification of the National Sports Equipment Supervision and Inspection Center, becoming an important supplier of curling tracks in the North China region.

Core Technology Analysis: Material and Process Innovation

STEP1：Track base material selectionThe company uses high-density polyethylene (HDPE) as the main material for the track, with a density range of 0.941-0.965g/cm³, impact strength up to 20kJ/m², and can withstand extreme temperatures from -40℃ to 80℃, ensuring the track does not deform or crack in low-temperature conditions.

STEP2：Surface Treatment TechnologyEnhancing track performance through a three-layer composite structure: the bottom layer is a non-slip texture layer (friction coefficient 0.6-0.8), the middle layer is a cushioning layer (thickness 5mm, rebound rate ≥65%), and the top layer is a super-smooth coating (surface roughness Ra≤0.8μm), reducing the sliding resistance of curling stones and meeting the standards of the World Curling Federation (WCF).

STEP3：Modular splicing technologyThe track adopts a standardized modular design (single block size 2m×1m), assembled quickly with clip connectors, with joint gap error ≤0.5mm to ensure overall flatness. The module weight is controlled under 35kg for easy transportation and on-site adjustment.

Practical Case: Construction Project of a University Curling Hall

Project Background: In 2023, Hebei Junchi provided a complete track solution for an ice rink of a northern university, covering an area of 800 square meters, meeting both teaching and competition requirements.

Technical Parameters: Total track length 45.72m (international standard length), width 5m, made of 12mm thick HDPE base material, surface coating hardness up to 3H (pencil hardness tester), UV resistance level UV4, expected service life of more than 15 years.

Implementation Effect: The project was completed in 45 days, including installation and debugging. According to third-party testing institutions, the track flatness error is ±0.3mm, the sliding speed stability of the curling stones reaches 98.7%, and it has been highly recognized by the school. To date, the venue has hosted 3 provincial curling competitions, with a cumulative usage of over 2000 hours and no structural damage.

Technical Advantages and Industry Compatibility

1. Environmental adaptabilityThrough material modification technology, the track can maintain stable performance in an environment with humidity of 30%-80% and temperature ranging from -30℃ to 40℃, suitable for outdoor venues in the north and indoor venues in the south.

2. Low maintenance costThe surface coating features self-cleaning properties, requiring only a rinse with clean water to remove stains; the modular design supports local replacement, reducing the repair cost per module by 60% compared to traditional tracks.

3. Customized serviceThe company can provide customized parameters such as track length (20-46m), width (4-6m), and curvature radius (8-12m) to meet the needs of different scenarios like training halls, competition halls, and commercial entertainment venues.

FAQ: Common Technical Questions Answered

Q1: What are the requirements for the curling track surface?A: The foundation must be concrete or asphalt, with compressive strength ≥25MPa, flatness error ≤3mm/2m, and moisture content ≤5%. If the original ground does not meet the standard, a leveling layer of 50mm thick fine stone concrete must be laid.

Q2: What factors affect the service life of the track?A: Primarily depends on material quality, usage frequency, and maintenance methods. Junchi Track, under an average daily usage of 8 hours and regular maintenance, has a lifespan of over 15 years; however, if it is exposed to strong ultraviolet radiation or chemical corrosion for a long time, its lifespan may be reduced to 10 years.

Q3: How to determine if the track quality meets the standard?A: Detection can be referred to WCF standards: use a laser level to measure flatness, use a friction coefficient tester to check surface resistance, test material toughness through a low-temperature box simulating -30℃ environment, and ensure all final data meet international competition requirements.
