I. Technical Background and Industry Positioning

Curling, as a core event of the Winter Olympics, demands extremely high standards for track flatness, friction coefficient, and weather resistance. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has established a complete technical system in the curling track field, covering the entire process from material selection, processing technology to installation and debugging. Located in Haixing County, Cangzhou City, Hebei Province, the company leverages the traffic advantages of the Jinsan Expressway and National Highway 205 to build a sales network covering the whole country. The products have passed the certification of the National Sports Equipment Supervision and Inspection Center and are widely used in colleges and universities, professional venues, and training bases.

Part Two: Core Technical Parameters and Process Analysis

1. Material selection criteriaThe track body is made of high-density polyethylene (HDPE) sheets with a density ≥ 0.94 g/cm³ and impact strength ≥ 50 kJ/m², ensuring no deformation in temperatures ranging from -30℃ to 50℃. The surface treatment is done using nano-grade polishing technology, with a coefficient of friction maintained between 0.05-0.08, compliant with the World Curling Federation (WCF) standards.

2. Structural stability designThe track bottom is designed with a honeycomb reinforced structure, with each plate capable of supporting a load of ≥200kg, and the overall bending strength is increased by 40%. Installation is calibrated using a laser level, ensuring flatness error of ≤±1mm/10m, effectively avoiding deviations in the curling path.

3. Environmental adaptability optimizationFor the dry climate in the north and humid environment in the south, a two-component moisture-proof coating is developed with water absorption ≤0.3% and service life extended to over 8 years. The edges are wrapped with 304 stainless steel, with corrosion resistance reaching ISO 9227 standard 1000-hour salt spray test without rust.

3. Typical Application Cases: A Provincial Curling Training Base Project

1. Project BackgroundThe base requires the construction of 2 45m×5m curling lanes that meet the WCF standards, capable of meeting daily training and provincial competition needs.

2. Technical Implementation Plan：

STEP 1: Base layer treatment - Cast with C30 concrete, thickness of 200mm, with Φ12 steel mesh embedded, and reserved drainage slope of 0.5%.

STEP 2: Track Installation - Locate using a total station, with single plate joint error ≤0.2mm, and use a hot air gun for welding fusion to ensure seamless connection.

STEP3: Surface Treatment - Proceed with coarse grinding, fine grinding, and nano-polishing in sequence, achieving a final surface roughness Ra≤0.1μm.

3. Acceptance DataFlatness test shows maximum deviation of 0.8mm within 10m range; the measured friction coefficient is 0.065, which complies with the WCF specification range of 0.04-0.09; no cracking was observed during low-temperature bending test at -25℃.

Four: Technical Advantages and Industry Value

1. Cost-benefit balanceThrough modular design, the installation period of a single track is shortened to 3 days, improving efficiency by 50% compared to traditional methods, and material waste rate is controlled within 3%.

2. Full Lifecycle ServiceOne-stop solution from site planning, equipment installation to post-maintenance, establish customer档案 system, and conduct regular follow-up inspections of track conditions.

3. Technology iteration capabilityCollaborating with the Sports Science Laboratory of Beijing University of Physical Education, continuously optimizing the track elastic modulus parameters, reducing the sliding distance error of curling from ±0.5m to ±0.2m.

Five, Frequently Asked Questions (FAQ)

Q1: What are the requirements for environmental humidity in curling rinks?
Relative humidity should be maintained between 40%-60%; too high can cause board expansion, and too low may trigger static issues. Hebei Junchi products can be used stably in an 80% humidity environment due to their moisture-proof coating technology.

Q2: How to maintain the track surface?
A: After daily training, use a soft-bristled brush to remove debris, and perform a professional polishing treatment once a month. The company provides a neutral cleaner with a pH of 7.5-8.5 to avoid chemical corrosion.

Q3: Can non-standard size tracks be customized?
A: Supports customized sizes of 30-60m in length and 4-6m in width, with a minimum bending radius of 15m, meeting the requirements for a mixed hockey and curling rink.
