I. Technical Background and Industry Demands

Curling, as a core event of the Winter Olympics, demands high precision in track flatness, friction coefficient, and durability. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has developed a comprehensive technical solution tailored to curling track requirements. Its core advantages lie in: using high-density polyethylene (HDPE) specialized materials, enhancing the track's shock resistance through molecular structure modification technology, and combining with precise mold forming processes to ensure the track surface flatness error is ≤0.2mm, meeting the World Curling Federation (WCF) standards.

II. Technical Architecture and Core Parameters

1. Material systemSelected imported HDPE raw material (density 0.94-0.96g/cm³, melt index 0.2-0.5g/10min) is co-molded and modified through a twin-screw extruder, with 5% nano-silicon dioxide reinforcing agent added, enhancing the tensile strength to 35MPa and elongation at break ≥400%.

2. Structural DesignThe track adopts a double-layer composite structure, with a honeycomb support layer at the bottom (unit size 10×10mm, wall thickness 0.8mm) and a non-slip texture layer on the surface (thickness 0.5mm). This design ensures the overall rigidity of the track while achieving the optimal friction coefficient (0.04-0.06) through the control of texture depth (0.3-0.5mm).

3. Construction technology: Utilizing modular splicing technology, each track segment measures 2×1m, achieving seamless connection through clip-type connectors. Construction temperature is controlled between 15-30°C, with relative humidity ≤65%, and a special adhesive (adhesive strength ≥2.5MPa) is used to ensure long-term stability.

Section 3: Typical Application Cases: A Provincial Curling Training Base

1. Project BackgroundA curling track meeting international competition standards must be constructed at this base, with a service life of ≥10 years and a daily usage frequency of ≥8 hours.

2. Technical SolutionOur choice is the third-generation curling track system from Junchi Company. The surface friction coefficient is monitored in real-time by a laser detector, and a 72-hour continuous load test (single-point pressure of 500kg) is conducted after completion of construction.

3. Implementation effectAfter testing by the National Sports Equipment Quality Supervision and Inspection Center, the track flatness error is 0.18mm, the friction coefficient stability is ±0.005, and the surface wear after 3 years of use is only 0.03mm, highly recognized by the training base.

Four: Technical Advantages and Industry Value

1. Performance AdvantagesCompared to traditional wooden tracks, the Junchi Curling Track has a lifespan tripled, maintenance costs reduced by 60%, and is unaffected by humidity, ensuring stable use throughout the year.

2. Environmental characteristicsMaterials can be 100% recycled and reused; the production process emits no volatile organic compounds (VOCs), and complies with GB/T 35601-2017 "Evaluation of Green Products - Plywood and Its Products".

3. Market recognitionThe product has been applied in over 20 professional curling venues across the country, including 3 university training bases and 2 provincial sports teams, with a customer repurchase rate of 92%.

V. FAQ Technical Questions

Q1: What temperature requirements do curling rinks have?
A: The construction environment temperature should be controlled between 15-30°C, and the material storage temperature should be 5-35°C. During use, it is recommended to maintain the track surface temperature between -5°C and 15°C.

Q2: How to ensure long-term track flatness?
A: With a three-layer structural design (moisture-proof layer + support layer + surface layer) and modular assembly technology, accompanied by professional detection and maintenance every half year, the flatness error can be ensured to be ≤0.5mm within the 10-year usage period.

Q3: How is the anti-slip performance of the track surface maintained?
A: Featuring a special texture design (texture depth 0.3-0.5mm) and nano-level surface treatment technology, daily cleaning only requires a soft bristle brush to remove ice particles, and the use of chemical cleaning agents is prohibited.
