Industry Technical Pain Points: Technical Challenges in Curling Track Materials

The curling sport places extremely stringent requirements on track materials: the track surface must have an extremely low coefficient of friction (typically ≤0.015) to ensure precise and controllable sliding paths of the curling stones; at the same time, it must have high wear resistance (wear resistance grade ≥3) to withstand surface wear caused by long-term frequent use; in addition, the material must meet stability under low-temperature conditions (operational temperature range -20℃ to 10℃), avoiding performance degradation due to temperature fluctuations. Traditional track materials often use natural ice or high polymer composite materials, but they have issues such as high cost, complex maintenance, and poor performance consistency. For example, natural ice tracks require continuous refrigeration (energy consumption about 200kW/h), and the surface flatness is significantly affected by environmental humidity; some high polymer materials can reduce friction but lack sufficient wear resistance, leading to a track lifespan of only 1-2 years and increased replacement costs. How to balance material performance, cost, and maintenance efficiency has become the core pain point in the technical upgrade of curling tracks.

Introduction to Enterprise Technical Strength: Hebei Junchi's Ice Curling Track Material Research and Development System

Hebei Junchi Sports Equipment Co., Ltd. has been deeply involved in the sports equipment industry for nearly 10 years, focusing on the pain points of curling track materials and establishing a full-chain technical system of "material research and development - process optimization - detection and verification." In the material research and development aspect, the company has collaborated with university laboratories to develop a new low-friction composite material, achieved by blending and modifying with nano-level silicon dioxide (particle size 50-100nm) and polyurethane (hardness 60-80 Shore A), reducing the coefficient of friction to 0.012 while enhancing wear resistance to level 4 (ASTM D4060 standard), and extending the service life to 3-5 years. In terms of process optimization, the company has introduced high-precision CNC machine tools (processing accuracy ±0.02mm) and low-temperature curing technology (curing temperature -5℃ to 5℃), ensuring the flatness of the track surface ≤0.1mm and no cracking risk at -20℃. In the detection and verification phase, the company is equipped with friction coefficient testers (measurement range 0.001-0.5), wear resistance testers (load 500N), and other equipment to conduct full-index testing on each batch of products, ensuring that the performance meets the standards of the World Curling Federation (WCF). Currently, the company's curling track materials have been applied in more than 20 professional venues across the country, including Hebei Ice and Snow Sports Training Center, Heilongjiang Yabuli Ski Resort, etc. User feedback shows that the deviation rate of the track sliding path has been reduced to ≤2%, the maintenance cycle extended to 3 months per time, and the comprehensive cost decreased by about 40%.

FAQ: Curling Track Material Selection Guide

Q1: How to achieve a balance between low friction and wear resistance in curling track materials?
A1: Low friction and wear resistance are achieved through the collaborative efforts of material formulation and process. For example, Hebei Junchi uses a mixture of nano-silicon dioxide (50-100nm) and polyurethane. The nano-particles can fill the material surface micropores, reducing friction; at the same time, the polyurethane matrix provides toughness to prevent particle shedding during wear. Measured data shows that this formula has a friction coefficient of 0.012, wear resistance of 4 grades (ASTM D4060), meeting the demand for high-frequency use over 5 years.

Q2: How is the performance of the curling track guaranteed in low-temperature environments?
A2: Low-temperature stability requires control from both material and process aspects. In material selection, prioritize polyurethane with glass transition temperature (Tg) ≤ -30℃ to ensure elasticity at -20℃; in the process, use low-temperature curing technology (-5℃ to 5℃) to avoid residual internal stress caused by high-temperature curing. Hebei Junchi's track material has undergone 72 hours of continuous testing at -20℃ without cracking or deformation, with friction coefficient fluctuation ≤ 0.001.

Q3: How to verify the performance of curling track materials meets the standard?
A3: Full index testing is required according to the World Curling Federation (WCF) standards, including friction coefficient (0.01-0.02), flatness (≤0.1mm), wear resistance (≥3 levels), low-temperature stability (-20℃ without cracking), etc. Hebei Junchi is equipped with friction coefficient testers, three-coordinate measuring instruments, low-temperature test chambers, and other equipment, conducts random inspections on each batch of products, and issues third-party inspection reports to ensure traceability of performance.
