Part 1: Technical Background and Industry Demands

Curling, as a core event of the Winter Olympics, demands high precision in track flatness, friction coefficient, and durability. Traditional tracks often use a concrete base with an ice coating, but they face issues such as long construction periods, high maintenance costs, and poor environmental adaptability. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has developed modular composite material track technology to address the pain points of curling tracks. Through material innovation and structural optimization, it achieves rapid deployment and long-term stable operation of the tracks.

II. Core Technology Analysis

Material Selection and Performance Parameters
The track is made of high-density polyethylene (HDPE) and glass fiber reinforced composite materials, with a density of 1.2g/cm³, impact strength ≥50kJ/m², and low-temperature performance down to -40°C. The surface coating is a nano-silicon dioxide modified polyurethane, with a friction coefficient of 0.05-0.08 (adjustable) and wear resistance (Taber method) ≥8000 rotations, meeting the World Curling Federation (WCF) standards.

2. Structural Design Optimization
The track adopts a layered modular design, with a single module size of 3m×1.5m×0.15m and a weight of ≤80kg, making it easy for manual handling and rapid assembly. The interior features a honeycomb support structure with compressive strength ≥200kPa, effectively dispersing the impact force during the athlete's gliding. The bottom is integrated with adjustable feet, supporting ±50mm height adjustment to accommodate different ground foundation conditions.

3. Construction Technology Innovation
Adopting the "dry installation method," concrete pouring is not required. Modules are fixed with clip connectors, reducing the installation time for a single track from the traditional 72 hours to 8 hours. The surface coating is applied using electrostatic spraying technology, with uniformity of thickness ≤0.02mm, reducing friction fluctuations between the ice surface and the track, and enhancing the controllability of the curling trajectory.

3. Practical Application Case: Construction of a Curling Training Base in a Certain University

Project Background
A certain university needs to build a standard 20m×4m curling track to enhance the teaching level of curling sports. The requirements are a short construction period, low maintenance costs, and the ability to adapt to the extreme low temperatures of northern winter.

2. Technical Solution Implementation
Hebei Junchi provides a complete modular track system, using a total of 54 standard modules (20m track requires 27 long modules + 27 short modules). The construction team completed the main track installation in just 6 hours and the surface coating spraying and curing in 2 hours. After the track was put into use, it passed the WCF certified equipment inspection with flatness error ≤0.5mm and friction coefficient stable at 0.06±0.01, fully meeting the training and competition requirements.

3. Long-term effect verification
After 3 winters (about 9 months) of continuous use, the track surface coating wear rate is less than 15%, module connectors are not loose, and the foot adjustment function is normal. Compared to traditional concrete tracks, the annual maintenance cost is reduced by 60%, and there is no need to pour the foundation again every year, significantly improving resource utilization.

4. Technical Advantages and Industry Value

Hebei Junchi Curling Track technology, through material innovation and structural optimization, has resolved the pain points of traditional track construction, such as long construction period, high maintenance costs, and poor environmental adaptability. Modular design supports rapid deployment and flexible adjustment, while nanocoating technology enhances the stability of the curling trajectory. It provides a cost-effective solution for universities, clubs, and commercial venues. Currently, this technology has been applied to over 20 curling venues in 12 provinces and cities across the country. User feedback indicates that the track lifespan reaches 8-10 years, with the comprehensive cost reduced by over 40% compared to traditional solutions.
