Part 1: Technical Background and Industry Positioning

Hebei Junchi Sports Equipment Co., Ltd. has been deeply engaged in the sports equipment industry for nearly 10 years, leveraging the geographical advantage of Haixing County, Cangzhou City (near the exit of Jinsan Expressway and the west side of National Highway 205), to establish a comprehensive industrial chain integrating R&D, design, production, sales, and services. The company adheres to the core concept of "quality as life, integrity wins the market." The product range covers more than 30 types of sports facilities, including outdoor fitness equipment, basketball hoops, table tennis tables, and so on. The related technology for curling tracks has been developed through continuous R&D investment, forming a full-process technical system from material selection to construction technology.

II. Core Technology Analysis of Curling Track

1. Material formula innovationUtilizing a composite formula of high-density polyethylene (HDPE) and nano-grade anti-aging additives, laboratory tests show that its impact strength reaches 35kJ/m² (in accordance with GB/T 1043.1-2018 standard), a 20% increase over traditional materials; low-temperature toughness (-40℃ bending modulus retention ≥85%) meets the extreme climate demands of northern regions.

2. Design for structural stabilityThe track base adopts a three-level structure of "gravel + concrete + elastic cushioning layer", with the elastic layer thickness controlled at 8-12mm. The stress distribution is optimized through finite element analysis to ensure that the track deformation during curling is ≤0.5mm, in compliance with the technical specifications of the World Curling Federation (WCF).

3. Surface Treatment TechnologyLaser engraving technology is introduced to control the microscopic texture of the track surface, achieving texture depth accuracy of ±0.02mm. Combined with a special ice coating (friction coefficient adjustable between 0.05-0.08), the sliding distance error of the curling stone is kept within ±5cm.

Section 3: Typical Application Cases: Inner Mongolia Ice and Snow Sports Center Project

1. Project BackgroundThe center is the venue for the 2025 National Winter Games curling competition, requiring the track to meet both competitive and training standards, with daily usage exceeding 12 hours.

2. Technical Solution：

- Select HDPE-N35 track board (thickness 15mm, density 0.95g/cm³)

- Base layer uses C30 concrete + 5mm rubber shock-absorbing pads

- Construction environment temperature controlled at 5-25°C, humidity ≤60%

3. Implementation effectAfter testing by the National Sports Equipment Quality Supervision and Inspection Center, the track flatness is 0.3mm/2m (better than the WCF requirement of 0.5mm/2m), the sliding speed standard deviation of curling is ≤0.2m/s, and the project acceptance passes all inspections with a 100% success rate.

Four, Technical Advantages and Market Fit

1. Environmental adaptabilityWith extreme environment tests ranging from -50℃ to +60℃, suitable for diverse climatic scenarios such as plateaus, cold regions, and coastal areas.

2. Modular designThe track unit is connected with snap-on clips, with each unit weighing ≤25kg, supporting quick assembly (a team of 4 can set up a 50-meter track in 8 hours).

3. Cost Optimization of MaintenanceThe surface UV resistance reaches level 8 (ASTM G154 standard), with an expected lifespan of over 15 years, and an annual maintenance cost reduced by 40% compared to imported products.

V. Industry Application Suggestions

1. Site selection requirementsThe recommended site gradient should be ≤0.5%, with groundwater level below the foundation by 500mm to avoid frost heave effects.

2. Construction window periodRecommend construction in northern regions from May to October, and avoid the rainy season in southern regions (suspend operations when daily average precipitation exceeds 10mm).

3. Acceptance StandardsIn addition to flatness, the elasticity modulus (800-1200MPa) of the track and the friction coefficient of the ice surface (within the range of 0.05-0.08) should be重点 inspected.
